Works, but may need adjusting
This controller works great with the 1/2 HP DC motor I bought to run my wood lathe. I did need to open it up to adjust the voltage pot as it originally did not deliver the full 90V as others have mentioned. But after that it has been working perfectly for a year now. I also bought a polarity reversing switch so the motor can run in both directions, which is nice for sanding turned items.

    No circuit diagram,. It would be useful to have a range adjustment pot. I use it on a 1 hp. motor, and the speed range is all in only a quarter turn of the control.

    Needed to be calibrated was easy to increase voltage to 90V but could not control minimum voltage. It would have been good if it came with instructions, wiring diagram etc.

    I bought this to pair with a 90vdc 1/4HP 2.5 amp 1725rpm motor for my mini lathe.
    It took about two minutes to hook up and it seems to work well, it has good torque at low rpm.
    I am measuring 81vdc out of the box and with the pulleys I have it is scary fast.
    I ran it for about 20 minutes and so far have had no issues.
    Good product, fast delivery and a fair price.
    What more could you ask for.
    Thanks!
