Thanks, mr. Majumdar, one more question, what diameter should the iron core of L1 have? Hi Swag, Your site is awesome. Alternatively you can also try Mosfets in place of BJTs and that would work equally good, according to me. Yes, you are right the NOT gates won't be required in the referred diagram. The capacitors can be rated at 25V or above. Thank you so much. and the transistor must be changed with suitable ones which can handle the applied volatge and current such as this one, https://homemade-circuits.com/2013/12/high-voltage-high-current-transistor.html, Hi Majumdar.How are you?I'm having a 2.5HP 180v DC Treadmill motor. How about 2 or even 3 ST901T's in parallel? . here a link of my half work so far. Thanks, Swagatam. The shown pot could be used for the required speed control. everything is clearly shown in the diagram if you are unable to read the symbols you need to study the basics first and proceed gradually. I don't know only what should be those Darlingtons? I got it off a treadmill and the ratings for it are; D.C. 120 Volts Permanent Magnet, 2.7 Horsepower, 19 Amperes. also the design calls for ICMM74C14 can ic4049 be used intead? You can insert the coil afterwards once all the testing is completed. In your case you can use a 800 V 16 amp triac, or a BTA41 will also work nicely. The circuit looks like it is for a 12v motor. I need few answers:1. Many thanks Sir. the dimmer chopper circuit above can be used as is it, or some components should be changed. Thank you very much for the quick answer. Tell him to design a transformer which would be able to supply 150V/6amp from 220V….this output can be then bridge rectified and filtered to acquire the required 180v for your motor. The circuit of a simple speed controller for a mini DC motor, such as that used in tape recorders and toys, is shown in Fig. I don't intend to use MOSFETs anymore.

I want to build this diagram for my bench lathe. This seem lot better? Hi Majudar,I want to construct a motor controller based on the open source design here, https://www.dropbox.com/s/if915wxhl8ninua/osmc3-2%20sch.pdf?dl=0. It was BTA41/600 already. I have a treadmill which controller chip has failed and now i would like to build independent control of the motor. Would there need to be any programming done to make this work or does the hardware do all that automatically? It indicates the (0) volt line or the negative volt line. So, what are the difference between those pairs? Refer to your original order to verify the warranty period purchased. Replace the circuit with new transistors and try operating the treadmill without any load, check the response, the other reason could be wrongly configured BJTs. When the pot is at min. Hi sir, I have a DC motor which uses electromanets where Armature Voltage is 70VDC and Field voltage is 90 VDC.Just help with a circuit diagram to power & regulate the speed, thanx. Why are the BJTs better here, as I understand BJTs are preferred for low current applications, while MOSFETs are for high power functions. make sure to use a 100K resistor in series with the pot. 300ma AC and output: 12v 1a DC.. make sure to use 12V for the circuit and 90V for the transistor bridge section. ... Nordictrack C900i parts and Nordictrack T6.5s parts. An exercise treadmill having a direct drive AC induction motor controlled by an AC motor driver/controller. I can't see anything marked as 100 in the first circuit IC2 (pin3) above……. 1st of all thank you very much mr.swag for your technical explanation against my ques, let me try as u said, and i will reply, it is much appreciated Sincerely, JEMS JEHAN. I have a 2000W AC dimmer, a 50A 1000V bridge rectifier and a 400V 4.7uF capacitor across the DC output. But motor sounds like wizzz.

For 3 HP just make sure to replace the triac with a BTA41/600 so that it is able handle the rated current comfortably, Swag the new motor for the drill press is a D.C. dear sir i have one clarification, that i have few treadmill dc motor controller, i wanted to use these dc motor controller to some other dc motor same voltage speed variable operation purpose, but there is a speed feedback sensor, but in my project motor there is no speed sensor and also i no need to use it, so how can i deactivate the speed sensor circuit in the treadmill motor drive board, please? Home Decor. It came with a flywheel that weighed half a ton, so I removed it as it is going to replace an old AC 3/4 HP single phase, capacitor start. starting voltage/ current= 130vdc/16.2A cont. in the second circuit, remove the motor, the bridge diodes network..verify the circuit using an AC lamp as shown in the following lamp, if this doesn't work will mean your circuit is faulty somewhere, 1.bp.blogspot.com/-s2Fe-xTv4YA/T4V-Z597HLI/AAAAAAAABFk/mafeMQ6JYm4/s1600/How+to+Control+AC+Motor+or+a+Ceiling+Fan.jpg, connect a 100 watt bulb in place of the "AC motor" in the above link. have a question about the schematic with dimmer. I will recommend that you build the first diagram in the above article. P1 will need to be connected with an appropriately dimensioned series resistor so that the max voltage to the motor is restricted at 220V, because the rectified voltage could be well above 300V. Excuse me for the late reply. MC-2100/MC-2100E Motor Controller The MC-2100 combines a PWM motor controller with a power board. …please make sure the negative of 110V DC joins with the 12v negative of the circuit…. I have all part of the circuit (without reverse) stuff only IRF840PBF Instead of irf540. Required fields are marked *, on Treadmill Dcmd57 Control Board Wiring Diagram, Treadmill dcmd57 control board wiring diagram. Building an electronic circuit for achieving DC motor speed control may seem quite simple, and you should be able to find many such ordinary circuits dealing with speed regulation. It is designed to replace the combination of ... One difference between the MC-2100 and earlier controllers is that the on/off circuit breaker has its own connection directly on the board. 1). And how about a buck converter with flywheel circuit, just like in the link below? I am sending you an image of the wiring diagram for the treadmill. I am not sure about the torque issue, the dmmer will vary the average voltage level across the motor for the speed control, as per the pot operations. any pointer would help. It would be interesting to check the second circuit also, first by confirming it with an AC bulb and then reverting with the shown bridge network, a tachometer can be avoided by simply adding a resistor/capacitor network at pin5 of IC2 which will slow down the change regardless how fast the pot or the voltage is varied. Please clear this to me. I want to use the circuit to power a 180V 15A d.c motor but i don't know how to go about modifying the original circuit for this purpose. You can upgrade it by adding another NPN/PNP to convert it into a Darlington. I think that it's because of the high breakdown voltage of the BD3 diac. That why i'm asking the property value and which you used for the project that work and from there I cant experiment. Hello Swagatam, thanks for all the information you give us. The better! Then it’s fine Mah, you can use the last circuit which has a bridge rectifier with the dimmer input. As for the second one, I tried alll the things you said – removing the engine and the bridge and using a 100W lamp as AC load. I ran my 220 and 180 vdc motor by using a 4kw dimmer with bridge rectifier feeding the pwm circuit and worked very well. which triac did you use? Kindly help me out in this matter. Alright I have become more knowledgeable with symbol. In other words the upper transistors should be NPN and the lower ones PNP. I've checked the voltage and its varied while turning at the pot only the voltage varies between the 0.8 and 11 volts. 220VAC Motor Speed Controller Schematic. Thank you very much. does a triac always get hot in such circuits ? I used a light bulb as a load, because the motor is a very risky try. I do not have a knowledge about electronics and am desperate in powering up my treadmill. The idea with putting a powerful light bulb as a voltage divider is groundless because of the power it dissipates in the small area of the treadmills motor bay. Also how do you suggest I isolate the dpdt switch? Thanks Ivan, The diameter of the core could be such that it accommodates the 200 turns comfortably, it could be done over an iron bolt or screw…but the diameter of the wire should be more than the indicated 0.6 mm since the motor is rated to carry high currents…a 1.5 mm could be tried initially. Hi Jayanath, yes NPN is available but PNP is not available. There are many different kinds of Proform models. I never imagined that controlling the speed of a DC motor can be so difficult!!! In the main image L1 on the left is connected with C2 and R1 in the small image is connected with C3 and C4, am I … Sorry Michael, I guess I misread it, no problems, you can try the following diagram, this should work perfectly: Please make sure to Add a 1K resistor between pin5 of IC2 and the ground line, I forgot to show it in the diagram. MOTOR COMPARTMENT. So you will have to attach a large heatsink to the mosfet to control its heating, or add two mosfets in parallel, or use a 300 V 70 amp mosfet or similar which may have a much lower RDson resistance. it's clearly shown in the diagram, the point indicated "motor voltage" should be applied with the 130V positive, and the negative to the lower rail of the bridge….all the negative or the earth symbols must be made into a common line. a preamp stage is not required, the power device can be directly linked with pin3 of the IC….as shown in this example design: 1.bp.blogspot.com/-jONLYQ8Ehro/UkD_gzAjA-I/AAAAAAAAFSk/nt6vxMDF9RU/s1600/ELC+circuit.png, no matter how 220 v is rectified the result will be always dangerous for the lower rated motor….one solution would be to use a 50 V lamp in series with the motor in order to absorb the extra 50V, the ampere rating of the lamp should be identical to the motor…. I ran my motor on a paid 4kw dimmer with 8A bridge rectifier. Diagram Part # 42. Thanks Swagatam, I mean to use bridge rectifier after dimmer and not for low voltages. Connect a MOSFET with pin3. Ok thanks. Embedding it into the main circuit will give it a finished look. https://homemade-circuits.com/2014/09/automatic-pwm-door-openclose-controller.html. Is there an easy way to tell?Thanks again for your help. i unable to found magnet wires. Hello, mr Majumdar, I have something much simplier in view with respect to 180V DC treadmill motor control powered from 220V AC grid. Variac Circuit for Controlling Large DC Shunt Motors, Operating a DC Motor Clockwise/Anticlockwise with a Single Switch, Automatic Torque Optimizer Circuit in Electric Motors, Toy Motor Circuit with Timed Reverse Forward Action, https://www.homemade-circuits.com/0-300v-variable-voltage-current/, Small Signal Transistor(BJT) and Diode Quick Datasheet. the source of the mosfet will connect with the circuit negative. Healthier Living. The 220k should be adjusted such that transistor in the above link just begins conducting at 190V, an additional 22k preset could be used in series with the 220 k on the input side and used as a fine control preset, in the link above a bridge can be seen, which could be replaced with a single diode from the 220k preset upper lead to the 220V DC. Thanks for the example but . ... DIY Wiring Diagrams • - collection proform treadmill wiring diagram pictures wire mc rh b2networks co Treadmill … I thought the thyristor will work like half-wave rectifier together with the phase cut-off process. when I turn on and after 5 seconds I turn off the source because the mosfet gets hot. the transistor you mentioned in the part list is "Q1 = ANY 100V, 20AMP P-channel MOSFET". If the auto modes work and the manual does not, you probably need to replace the console. If the riac is appropriately ated it will be able to handle the initial surge. Also I’ve used 1N4744 as a D1.What do you think Sir. ….1N4744 are zener diodes and will never work here, you'll have to use rectifier diodes such as 6A4 etc. yes the existing mosfet will need to be replaced with a different mosfet having 200V/5 amp or nearby specs. FIGURE 2: Three-point manual DC motor starter circuit diagram. Now it looks very promising. Home Maintenance. From shoulders down with! Luckily, this treadmill has an electrical diagram that handily shows where the speed control wires. the uF rating has no relation to motor voltage. ". Then I can do it with a different setup. the zener can be a 2.7 V, 3 V or a 3.3 V zener, any minimum watt. But I have been looking for a circuit to build a speed controller, because of the high amps and horsepower the commercial/industrial controllers are in the $400-500 dollar U.S, range. I want to use a PWM module to control the motor. Thank you Michael for contacting me! You can add a optocoupler if you want, but it is not necessary. Thanks I am not sure what is starting voltage in your specifications, I think 110V should be the recommended voltage in any circumstances. . The other way is to use half-wave rectifier (single diode) and a capacitor behind it in order to get smoothed voltage with the value motor needs. The motor can be connected across positive 110V and the transistor collector. Dear Swagatam, many thanks for your fast replies.I’ve managed to put everything together and pluged in. The heating may be due to high resistance RDSon value of the MOSFET which is around 0.27 ohms. Like is 1 actually 1 and not some other pin? You're right. Hi, Could you explain how a constant torque at low speeds is achieved? Hey Swag, My first attempt to make the circuit as you suggest, was not successful but I am sure I will find a way to fix it ofcourse with your help. in the above article 555 IC are shown but if you wish you can use a single 556 instead of the shown two 555. voltage is not indicated because different users may have different voltage requirements as per their motor specs. 2. No it won’t, the design does not include a torque compensation feature. Treadmill motors can be purchased at exercise equipment outlets both online and in physical stores. I’m controlling a 180Vdc, 0.25kW PMDC motor using bluetooth, thus I can’t use 555 timer. The replacement motor control board is an MC and the original is an MC The wiring appears to be different and I want to know if I can use the MC and how to wire it. lastly do the uf ratings of the capcitors change with the higher vaoltage needed in my circuit? The NOT gates which act as inverters provide the feature of instant toggling of the motors rotational direction by a mere flick of the SPDT switch. Thanks for all your time. Now, i know i have to change to a mosfet with a current rating of about 15A based on my motor specification but i dont know how to make the system operate at up to 180V. Swagatam, thank you for your input. MODELS: F**** . And I just need a forward motion, so I am going to get rid of the whole H-bridge network. any advice is welcome. I mentioned that the treadmill has opto-tachometer originally. Once again thanks for your patience and time. Page 41: … Yes, but the original board was also powered by 220V without any lamps or otger resisting elements. HelloMy treadmill motor is rated for 130VDC and 15a. Once the triac blowed up and the motor raised its RPM's to the space before the fuse interrupted the mains circuit. I was intrigued by this circuit design because of “its capability of sustaining and balancing optimal torque even at lower speeds ensuring a continuous working of the motor without stalling it during extreme low speeds.” This is necessary for milling operations. Should I use some bigger capacitor (the original board had a 470uF/400V one). Murry Widebody Lt Model # 40508x92d Wiring Diagram, 2013 Dodge Dart Interior Fuse Box Diagram, Waterway Executive 56 Pump Wiring Diagram. Hello Njabulo, you can use the H-bridge section from the above design and use it with your Arduino, a pair of anti-phase signals will be required for triggering the bJT H-bridge and the PWM could be injected at the bases of the low side BJTs. IC1 works as a frequency generator and is rigged at around 80Hz, any other value would also do and is not anyway critical. you can try the first circuit from the above article, you can eliminate the S1 and N1—N6 stage completely, and join the R6/R7 ends together with pin#3 of IC2 for the required control. (No need for reverse direction)Please guide me through simpler circuit as I'm beginner. Hi Mr. Majumdar, is it possible for me to reach you through mail please? Does that work? Have three wires, red, white and green. Hi Mr. Mazumdar. https://www.homemade-circuits.com/wp-content/uploads/2020/02/treadmill-motor-speed-controller-circuit.jpg. Hi Ivan, you can try the following simple design, Just make sure that the circuit supply is acquired from a 12V AC/DC adapter while the motor terminal from a 180V Dc (+) source, The (-) of the 180V must be made common with the (-) of the 12V supply or the (-) of the circuit. That is already done. ""no matter how 220 v is rectified the result will be always dangerous for the lower rated motor…."". Will a single MJ11022 be enough as a power stage.I am about to use a ST901T as a preamp stage and two MJ11022 as power stage. Price: $19.99 # 058 Transportation Wheel(B) Diagram Part # 58. Stay blessed now and forever! a circuit is not about just building it exactly as shown, it's about knowing precisely how it's designed to function and troubleshoot the problems if anything goes wrong. The LED brightness must vary from 0 to max in response to the pot variations. I want to control it's speed from zero to max by powering it from 220V AC power grid. The circuit from the link you posted is with MOSFET, there's no problem to drive it directly from the IC, but in the first circuit above power Darlington BJT's are used. The circuit should be supplied with a separate 12V DC, whose ground must be made common with the 180V DC ground. It seems that the circuit must be without those NOT gates because of the single way rotation and I'll need only 2 power transistors (in parallel oor in sequence). or should replace it with a m11021 transistor instead? the mosfet upper lead which is drain needs to be connected with the motor negative, while the positive of the motor will connect with the 110V DC or whatever may be the motor operational voltage spec. With other words, there is not any stepless driving of the load – just on or off. The PWMs are fed across two sets of NOT gates via an SPDT toggle switch. These transistors should be rated as per the motor specifications, and the voltage across this bridge should also be as per the motor requirements. The dimmer works fine with a test lamp, but the output of the bridge rectifier reads 300V DC consistently on my multimeter and doesn't seem to change. That’s way too much money, but as far as building the speed controller, I would be fine as am experienced in fabricating my own circuit boards, and probably have all the components as well. BJTs are easier to handle than mosfets, so it's better to use BJTs here. I am also the founder of the website: https://www.homemade-circuits.com/, where I love sharing my innovative circuit ideas and tutorials. And what's so hard in the first circuit so I must be an expert in order to run it? Now I found another circuit in one of our old elctronic magazines (I'm from Bulgaria). example 10uf should it be 100v or 220v or 400v? As expected, it doesn't work. the 180V can be derived from either a step down transformer or from an smps adapter, which may be specially designed and procured for your application. Massimo, if it is a DC motor, then you must use the second last circuit, because 50 V cannot be used with a 220V input or a 120 V, even with a triac chopper. I plan on using 120vac(line voltage) and a bridge rectifier to power the motor. Here's a simple PWM based motor speed controller circuit which can be used for controlling a treadmill speed right from zero to maximum. Do you think I’m making a mistake? I replaced magnetic sensor still same issue. can i use MOSFET or any other for instead above sir? 2) The negetive line of 180VDc goes to common which indicated “0 in circle” in the circuit ! I am expecting your response regarding the MOSFET driver. the negative from the rectifier will connect with the negative of the circuit. 3). thanks again for early replies. Also you may have to change the transistor with 400 V transistors. Hello sir thank you for your time and the courtesy of putting these circut designs online. Hi Kakooza, if it's a DC motor then you can definitely use the first design which is explained in the above article. I have also some differences – I need one direction and have 180V DC motor at 2.2HP (that's 1640W of power). The list of elements is in bulgarian, that's why I'm not posting it here. please advise me how to deactivate the sensor circuit & optocoupler circuit? Ok great.. And that reminds me i forgot to mention for the 12v circuit i recall you mentioning an smps power supply however i dont know how to tell if it is a smps powersupply or not… im using a small ac to dc (wall dart) power adapter which belonged to a wireless router enclosure. Then the bulb got bright like it was in wall socket without any circuit. you can rather try the following circuit which is relatively simpler and will be suitable for your application: But the other diagram also includes a 12 volts dc motor and on my lathe is a 220 volt dc motor. Any advice or suggestions? . Hi Mah, I referred you the second last design, meaning the second circuit from bottom. i.imgur.com/VP0JdCE.png. If possible I'll try to update the design in the above article soon. TREADMILL WIRING DIAGRAM. I made the dimmer circuit as you shown here on assembly board(i mean not using soldering tools). ... Wiring Diagram. Dear sir can i buy from u dc motor controller ? I should say that C1,C2,C3 rated voltage are 100V. I don't recognize the symbol you used. Increasing the 220uF value increases the soft start effect and vice versa. ?thank you, please do exactly as shown in the first diagram, you will succeed in getting the intended results. Unlike your second circuit it uses thyristor (SCR), not triac. thanks in advanced, so i have this information, cc motor 2.0hpm 180v. I have a Sears treadmill model and ordered a replacement motor control board. Question The VCC is 15v but wasn't sure if it's DC or AC on your schematic. Hi Kamaal, you can try the second circuit from the above article. I don't have a heater coil, but I connected up a 100W bulb (40 ohms) in series with the motor to avoid drawing too much current. When the treadmill is started, it races at full speed for a few seconds then shuts off, while the console is still displaying that it's running. the diode polarities inside the bridge is incorrect, it should be exactly as given in my diagram. Even Mr.Samuel, the man who gave the request, did he run the circuit? Thanks for the great design! the 220k variable resistor controls the frequency of the soft start PWMs. MAIN CONTROLLER a) Contains power supply and control circuits. Does the C4 (10nF) stay at it's place in that case? Yes that's right! . but first make sure to test the dimmer circuit with an ordinary ceiling fan or a 200 watt bulb, before setting up the bridge and the treadmill motor. If you want the H bridge, then Darlington may not be required. Yes it should work properly for any load below 4000 watts 220V. Thanks for the reply, Mr. Majumdar, but the circuit you offer uses PWM. Description: Treadmills How To Read Wiring Diagrams Treadmill Circuit Diagram intended for Treadmill Wiring Diagram, image size 800 X 565 px, and to view image details please click the image. the word "simple" was mentioned in context to the subject….compared the complexity of the PWM concept this circuit looks easy that's was I meant to say in the article.. Glad you liked my site! Exactly that was my second question. Thanks again for all your help. .however for driving the MOC you'll need a PWM feed.". dear sir i also have 2 HP 180vdc treadmill motor. I saw some circuit like this with heat sink. My motor is rated at 130VDC 15A, i was going to power the motor with 110VAC thru a bridge rectifier, any ideas on what transistors to buy? Please remove the two BC547 transistors from pin5 of IC2, remove the associated parts like R9, C5, 10k pot. Use any 200V NPN transistor, connect its base with pin#3 of IC2 directly. 3. The driver/controller is itself controlled through programmable circuitry having a display and keyboard with user input options. make sure the triac is rated at 40 amps….use a BTA41600 type triac. The image that you ahve provided will controll speeds upti 50% only and will create lot of jerk at lower speeds….i already have a similar design posted in my blog here: https://homemade-circuits.com/2012/01/how-to-make-versatile-closed-loop.html. For some reason I was under the impression that connecting ground together from both circuits would allow high volts/current surge from the motor circuit to the controller circuit. Thirdly, could I use two NPN wired in parallel instead of a PNP / NPN combinations? 2). Just a single ST901T?! Hello Horacio, the 220uF can be seen at the base of the BC547 pair towards the extreme bottom right of the first diagram.
