A perfect smooth driving is not really necessary to me, it is used to drive a diy small flour mill. Do you have any idea what to do? 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. Please remove the two BC547 transistors from pin5 of IC2, remove the associated parts like R9, C5, 10k pot. The PWMs are fed across two sets of NOT gates via an SPDT toggle switch. It was BTA41/600 already. I have also connected the mosfet again and at its output I have placed a led with a 1K resistor with 12VdC power. If your treadmill won't run at the speed you set, the motor controller could be to blame. That's why I will try with the PWM concept, no matter of his complexity, not to mention that the original development used the same technology. Free shipping. as mentioned in above comments i should make first circuit and to be eliminated N1 to N6 and S1 joining R6&7 to 2nd ic pin 3. sir. Reliable Electric DC-2 Variable Speed Motor Controller. I suggested an SMPS since most smps have regulated output using zener controlled feedback. Almost like your circuit with a BTA41-600E triac. 1) my motor max 180VDC 300watts, i need speed controller from ZERO to 160VDC 2) another motor max 130VDC 300watts, i need speed controller from ZERO to 120VDC. I'm absolutely (120%) that it was correctly assembled. Very easy installation. You have a good day. It is PMDC (Permanent-magnet DC) motor, 180V, 6.8A. I want to use a PWM module to control the motor. But I have a question.

Proform Treadmill Motor Controller MC2100LTS-30 MC2100LS-30 REV 232196. Also what you think about tl494 in this case? I will take photos of the motor but it is a 160VDC and power in AU is 240VAC. Last Updated on April 25, 2020 by Swagatam 269 Comments. Hi, what is the wattage or current rating of your motor. I think it's time to show you my circuit under which I created the board. Mr. Majumdar, I didn't say anything about your first circuit, at least my was with MOSFET stage unlike yours. 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. 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. Pinout matching of the two ICs is not important, you just have to use the 4049 gates in the appropriate locations as indicated in the diagram, you can refer to the datasheet of the 4049 IC for learning the details. If you did, then I would suggest you to first confirm the IC2 pin3 output response with an LED. Are 100V enough for Q1 in my case?How about C3 (the reservoir capacitor) from the link? 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. Thirdly, could I use two NPN wired in parallel instead of a PNP / NPN combinations? Hi Swagatam, I have been working on the second circuit to control the speed of a 120VDC 2.5HP treadmill motor without reversing. I mistakenly thought that you had used the zener in the motor bridge circuit,….surely it will do in place of the shown 2.7V zener. Yes it should work properly for any load below 4000 watts 220V. Below the circuit you indicate “The 10K pot can be used for the speed control, while the 220uF determines the soft start feature. 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. Hello Swagatam, I am thinking of building the circuit without reverse to control a 120DC treadmill motor with 2.5 HP for which I will use the IRFP250 mosfet. On the nameplate of the lathe it says 220 Volt 800 Watt and i know that it is a DC motor. And is 100uF capacity enough? ….1N4744 are zener diodes and will never work here, you'll have to use rectifier diodes such as 6A4 etc. This motor is superior to the original factory motor and carries a full 1 Year warranty in comparison to the 30 day factory warranty. IRF540 mosfet is only 100v, I think. Dimmer circuits are voltage regulator and as you know it can support high currents consumer by using high amp triacs or thyrestors.
