I found it very hard in the beginning to find a pwm module because the reviews were very mixed, this helped clear it up a lot! Thanks!

I watch your every video, nice information in each video.

Still hoping the PWM control hack is coming soon. This seems to be the only motor controller that might work in my project for less than $150...but arduino control is critical. Thank you VERY much for all the info and your efforts!

Hello Ahmad, I bought this unit a couple weeks a go and tested it at 20 amps on resistive load. It is warming up around same area than yours. I was questioning it the heat was generated by the relay or copper traces underneath. Your tests are confirming I should not rely on it for the sawmill I'm working on unless a fan makes all the difference. BTW, mine shows about 3 sec ramp up time (soft start) when I turn it on with the pot. I would not recommend to change motor direction without first turning the pot to 0 or off on a bigger motor. Tks for the video

Hello, Thank you for sharing your experience. Thanks for the tip on speed to be turned down before changing the direction. very important.

60A is a no go without active cooling. Some of these do come with an enclosure. For trolling motors that does a full draw at 30A I guess it's fine.

thank you for this interesting test/review. i was planning to get one of these but now i see why it will not work for me. Is there a driver for the FET when you disconnect 555?

Nice review video 👏

I bought such a driver for an 1162W on 24v (48A) outboard. Hope I didn't make a mistake. It's nice that you shared your test - I think you should, however, load the controller with a more powerful motor to check the actual strength of the system. (google translate)

What's about 24vdc motor work on this product . Please reply me

Hey Ahmad, I'm using one of these controllers for a kid's power wheels toy vehicle. The problem I'm having is that the throttle pedal is just an on/off switch and I'm using the knob for speed control. In this case once the throttle pedal is released the car brakes violently because the controller shorts the motor windings at rest. I believe I could use a power resistor between the 2 pins normally shorted at rest on the relay to soften this? With there being 2 relays on this controller due to the forward/reverse selector do you know how/where to put the resistor so that it would brake softly in both directions? Thanks!

Hello, good evening, friend, this module does work with a 1000w 11A 15khz motor, and I have seen that it is installed on a small electric vote

Thanks for the video, this was very helpful. Did you manage to control it with arduino?

I want to know that when i connect motor of 24vdc 90w . And at full load can i change switch position, relay will damage after how much time i switch from 1-0-2 respite ( cycle test of relay ) . from my experience it will work for 1000 to 2000 time at full load .

Thanks Ahmed Very Good job man very good 👍 Waiting for the Arduino

спасибо большое за исчерпывающий видеообзор.

Would it be possible to run two or even three of these paralleled at the outputs? Also the speed control wire in parallel to always run them all at the same speed

I have blown up two of these units using them fot HHO gas Generation max 25 amp 12v I was Trying to fix them. on one the three number led gets very hot were you able to identify the driver chip. I looked at a Tm1637 but this is for a 4 number led any help would be appreciated.

Hi Ahmad. Did you ever get a chance to make the video about using this controller with PWM from arduino? It would be much appreciated! Thanks.

Nice video. What’s your conclusion? I ask this before finishing to the end. Sorry. How can I tell if this will work for my treadmill motor? I’m using a Lieli 4.25 hp, 130 VDC model number 116ZY1-1. It has four wires. 2 for power and 2 blue ones for thermal cutoff. This looks like a simple speed controller but I don’t know if it will work with my motor. Thanks, Paul

I haven't tried this particular model yet but I have used a bunch of similar PWM controllers. I keep ordering bigger ones as I blow them up pushing too much current in my wild quest for speed. I have made an electric wheelbarrow, bike and canoe motor so far. Biggest problem is that the ground trace heats up so much on the bottom that the smaller traces on the top delaminate, killing the circuit. Ones without fuses can be taken out by stall current and back EMF. I really wish there was a properly robust and well designed option available. The combination of high current and heat in close proximity to tiny SMD parts is bad design that is perpetuated through all of these devices, IMHO. Modern manufacturing styles. The higher current versions simply add parallel mosfets and then a fan, which is a "cludge" attempt to keep the PCB from melting down. That being said, when I used them more conservatively I had more luck. Just a normal electronics tech making motorized things for my own enjoyment, waffling on to nobody!

@robojax

thanks for sharing your thoughts. I agree with you. this is just putting multiple mosfets in parallel. The proper design probably would need only 1 or 2 of these mosfets with proper heatsink. Good luck with your projects.
