Wanting to power a lead screw

did you build that belt grinder?
Yeah, it would be nice to get it at that price. (Not that I think thats going to happen)
They say that KBIC 120 is a good board.

EDIT
Do you guys know if I can weld a bracket onto the motor case or maybe more so on to the bracket that is already
welded to the motor housing?
Will I do anything to the windings or the magnets, or should I just try to bolt something to the brackets.
It is still in the thought process, I am not sure if I have to weld onto it or not.

Look at the KK6039T
And look at the KBIC above.
Looks like a lot more components on the KBIC board.
Like I said, "They" say that KBIC 120 is a good little board.

On those little PWM boards we got, and you guys have mounted in a box, did you mount it (the board) on some type of plastic or rubber mounts?
Looks like I am going to need something to keep the solder joints from shorting to the metal box.
(unless l use a plastic box)
This is the little board for the wiper/leadscrew motor I am talking about now.
Also, do you think I need to run a fuse in the Hot wire feeding into my power supply.
I was fooling with it tonight, but I am going to have to get some different pulleys.
I had the lead screw geared down too much. I need a smaller pulley on the lead screw, or a bigger pulley on the motor.

Now that's awesome! Like "they" always say, it never hurts to ask... good on ya for doing so and nabbing the discount. Can't wait to see it/them in action... :)
 
I think the first question is: What is the HP or Amp rating on the controller that you have? If you have a 21 amp motor and are trying to run it with a 15 amp controller, it's probably not going to like it. Based only on that chart, it looks like the max is 15 amps, or 3 HP at 180 volts. If that is a 90 volt motor, you may have the wrong controller for it.

If you want to try it, then I would get the 0.006 ohm resistor. The controller will probably current limit anyway to protect it's self, so the motor may not develop it's full rated power.
 
When I first got the KBMD-240D I asked the seller what they recommended, and as your motor is similar to the one I used at the time... oughta be close. They said that the treadmill motors were not to be trusted, rated HP-wise, so went with a 1 HP resistor. Never had a problem, always ran fine if not up to its full potential if a higher rated resistor were used. If you have an empty 20A circuit available you might try the 1.5 HP resistor, but use the 1 HP resistor if on a shared or 15A circuit.

Hopefully, someone with practical experience/training will chime in and lead you in the straight and narrow if I'm off course here... :)
