Hi, Mr.Majumdar, the dimmer circuit simply does not work, I did 3 times, the load works always at the grid's voltage (220V), no matter the potentiometer setting. i unable to found magnet wires. Article from microcontrollerslab.com. the negative from the rectifier will connect with the negative of the circuit. please advise if there is anything else in the auto door control circuit I must change for it to work with my 250w 110v dc motor. You think do i need anything more to control the 180VDC, 5.5A motor? Can you give some circuit similar to the above one, but for 220V AC, please? My motor has the following spec. I hope it will work much better than the previous one. Thank you again for your time. kindly specify the suitable type. Have a nice time. 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? I plan on using 120vac(line voltage) and a bridge rectifier to power the motor. The reed switch for determining RPM appears to be functioning correctly, so I think the issue lies with the motor … According to the documentation provided, the circuit can handle currents up to 160A thanks to the IRF1405 mosfet in use. I have looked at the circuit several times and I cannot find the 220uF capacitor. You can upgrade it by adding another NPN/PNP to convert it into a Darlington. If the circuit is too complicated and the people who will try to build do not have even the slightest idea of how it works and how to be checked for troubleshooting, then what is this all about? . Hi Mr. Ivan, The first circuit has been tested by me not once but many number of times for different applications. 3. Please let me know how to run a 180v dc 5400 rpm 1.5 hp motor from a threadmill with 220v ac current here in India. Hi Rookie, to which diagram are you referring to?? can i use MOSFET or any other for instead above sir? How to fix your NordicTrack treadmill when it won't power up. . 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. … Hey guys, I was wondering if you could help me out with what I believe to be a faulty motor control board on my treadmill (Proform 565 Crosstrainer). Figure 3 shows a four-point starter circuit diagram. Hi, yes that’s possible..you can try the modifications as presented in the following circuit, https://www.homemade-circuits.com/wp-content/uploads/2019/11/90-V-treadmill-motor-driver.jpg, I have a motor to treadmill 180 volt 5.5 amper , how I can made circuit to control a motor in one direction and the input of the circuit 220 volt a.c. For the transistor you can simply use a single high voltage Darligton transistor such as ST901T with pin3 of IC2 for the required implementation. . I have checked their spec. To simulate the engine I used an incandescent lamp. Kindly correct me about the mentioned circuit about these concerns; 1) I need to convert 220Ac to 180VDc and connect the positive to place indicated as +12VDc in the Circuit ! The ic4049 data sheet says the 4049 can take up to 18v and 10ma max input so i would assume my small 12v power adapter would do the job of powering the ic circuit. 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. 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. yes 13/14V will cause no harm to the circuit although a fixed 12V is the recommended value….initially you can go ahead with your available set up, and see how it responds. thanks in advanced, so i have this information, cc motor 2.0hpm 180v. Here's a simple PWM based motor speed controller circuit which can be used for controlling a treadmill speed right from zero to maximum. voltage/ current? The speed cannot be adjusted from zero (at least not in my case) and is unstable. Would there need to be any programming done to make this work or does the hardware do all that automatically? Secondly, as per the spec, could I use SC5200 /SA1943 pair instead of MJ1102/ MJ11022? 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. 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. the PWM pot can be appropriately set such that the maximum output never exceeds the 110V DC for the motor. Treadmill motors can be purchased at exercise equipment outlets both online and in physical stores. How about just changing the gate voltage in order to control the drain current? I have all part of the circuit (without reverse) stuff only IRF840PBF Instead of irf540. When I turn the 10K potentiometer from zero to the maximum value, the voltage drop between the negative leg of the led and the leg of the resistor connected to the positive reaches 12V when the potentiometer reaches 1.2K. And which circuit do you recommend to build, I just am sick of moving the drive belt to change speeds, that explains the DC motor as am looking for variable speed on a single pulley. Could you show us what this circuit would look like without the components necessary for the reverse feature and how I could make this work using 110vac i.e. Treadmill Doctor is your source for treadmill and elliptical parts. any other replacement or combination sir? Hello again Sir, I have a general question regarding dimmer circuit. That’s equal to around 8 amp current, and the MOSFET is rated to handle 20 amp, so its fine. However, practically you will find that simpler circuits have one serious drawback – they are not able to control the motor speed smoothly at lower levels, and as the desired speed is decreased, the torque of the motor also decreases proportionately. the BC547 should be actually BC557, please note this. IRF540 mosfet is only 100v, I think. Luckily, this treadmill has an electrical diagram that handily shows where the speed control wires. The motor can be connected across positive 110V and the transistor collector. With details on pinout diagram, examples, applications and download datasheet. Thank you so much. To control the speed of a 120VDC 2.5 HP motor, should I use the second circuit? Diagram Part # 42. I thought the thyristor will work like half-wave rectifier together with the phase cut-off process. Once again thanks for your patience and time. VFD Start Stop Wiring Diagram: I am here with giving you a VFD start stop wiring diagram for running a VFD through panel board push button and keypad of the VFD (It is called HMI).. Vfd is a short form of variable frequency drive or variable voltage variable frequency drive.The VFDs are working based on changing the input frequency and input voltage of the motor, we can change the speed of the motor. DPDT can be used for reversing the motor manually instead of the bridge network. Or should I be looking at a different approach to driving that big D.C. Why?! The circuit should be supplied with a separate 12V DC, whose ground must be made common with the 180V DC ground. The idea was requested by Mr. Samuel. Are 100V enough for Q1 in my case?How about C3 (the reservoir capacitor) from the link? must feed 180v treadmill motor. Horacio from Argentina. 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 … The parameters are:– 220V AC power grid– 180V permanent magnet DC motor 7Amps motor– main control element a SCR (thyristor) simultaneously acting like rectifier and control element with phase controlling circuit– a capacitor in parallel after the thyristor acting simultaneously like smoothing element for the phase-cutted sine and voltage-raising capacitor (just like in the last circuit you offered me).– a SCR control circuit that uses phase-cut method – cutting the sine at different angles in order to get different voltage values above the motor. Hey Mah, it is a tested design so it should work. This seem lot better? I want to ask you if I am connecting the circuit wrongly? I'll do some more search and let you know soon if I happen to find one….if finally we are unable to find any, we can go for non-Darlington PNP BJTs with a supporting smaller PNP and configure the two like a Darlington. How abot slowing the on threshold of the second circuit, it's the main disadvantage of it? yes you can use a MOC3043 IC for driving your motor and I think it would make things much safer, however for driving the MOC you'll need a PWM feed. Hello Jems, you can remove the entire sensor opto stage to remove the feedback. Thanks! Jayanath, I could not find any BJTs rated at 400 V 10 amps, so I think you should try the last concept instead. Can you name a proper model for T1~T4? Is the capacitor too big/small? best moments! IC2 responds and starts oscillating at this frequency, forcing equivalent triangle wave frequency at its pin2/6. is it getting hot?….you can first test the circuit with a 200 watt bulb and make sure the bulb dims across the entire pot rotation uniformly…. ok so just connect the 130dc on the plus where the motor is connected and the – to 0 rail : I don't understand how the motor would get the pluses. I have been planning to use Arduino UNO, the problem is finding the relevant H-bridge driver since the PWM from the arduino is about 5V. There were much more tricky circuits I created at once. The follow-up question of how we may make the motor stop running is a very important one. Thanks I am not sure what is starting voltage in your specifications, I think 110V should be the recommended voltage in any circumstances. Sorry Linus, that may not be possible because I have not seen the board practically so have no idea regarding the various stages. Thanks for paying attention to me and my problems, will find the solution with the first circuit!Best regards, Ivan! Glad you liked my site! Explore. I have read all those post and many picture of schematic I have Permanent Magnet DC Motor with specs of Volts 130 , AMP 10.0 . Your timely help would be highly appreciated, Thanks & Regards Linus Fernandez. Last Updated on April 25, 2020 by Swagatam 269 Comments. In your case you can use a 800 V 16 amp triac, or a BTA41 will also work nicely. 3) Which IC’s should be selected for the circuit ; LM555J, LMC555, BCR555, ICM555CD, NE555P, NE555DR, or ICM7555CD? I think is possible to use a controller for an Ac motor made with triac and diac and then to use a rectifier bridge to feed the motor. Also what you think about tl494 in this case? 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. I've checked the voltage and its varied while turning at the pot only the voltage varies between the 0.8 and 11 volts. i feel more comfortable interacting through my blog…, does cap on schemetic what voltage should they be on? ... wiring diagram for treadmill motor control, trojan treamill motor dive board wiring diagram, treadmill schematic diagram, wiring diagram a tread mill motor and controller diagram, treadmill/triump rti 8 … Power & Electrical Supplies .. The motor voltage is 180V and the grid's voltage is 230V AC. The bulb gets brighter and dimmer and the voltage across it varies nicely from 0V to 220V, but the motor is not moving at all.Do you think the bulb is providing too much resistance? 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. Hi Kakooza, if it's a DC motor then you can definitely use the first design which is explained in the above article. I really don’t know if that is possible and even more I don’t know how to handle the high starting current of the motor. The above triangle waves is instantly compared by the set potential at pin#5 of IC2 creating an equivalent level of chopped PWM at its pin#3. I mean like mosfets. I finished my tests with dimmer driving of PMDC motor 8 months ago and I rate them as danger and unreliable with regard to safety and stability. Then the bulb got bright like it was in wall socket without any circuit. It's been very helpful. you can try the first diagram for your application but you should have an access to 130V Dc for supplying the motor via the transistor bridge, an ordinary SPDT switch will be enough for the reversal, couple question base on the image here the link i.imgur.com/IxaxT14.png, N1—N6 are the gates from the IC 4049, refer its datasheet for a clearer view. The speed of the motor will equalize with the speed set by the user, but slowly which prewents this rapid change of the voltage/current. Let me know if there's something wrong with the circuit . here a link of my half work so far. Stay blessed now and forever! Treadmill Motor Speed Controller Circuit | Homemade Circuit … Which of your diagram should I use to power this motor and use 10k pot to control from 0 to max and I would like a reverse on motor can DPDT switch will do? Many thanks Swagatam.New high voltage transistors just been ordered. Excuse me for the late reply. Hence the question for the torque. Thank you again for your help and sorry for lack of information. I have a treadmill which controller chip has failed and now i would like to build independent control of the motor. I mentioned that the treadmill has opto-tachometer originally. Motor controller. Also, the circuit has an HIP4081A mosfet driver, please can you briefly explain how a mosfet driver works and whether this particular mosfet driver will be appropriate based on the ratings below. Hello Swagatam, thanks for all the information you give us. Jems, you can use the second last circuit, it will work perfectly as per your required specifications. Would 1N4007 would do it?
