Please move this ti a better thread if you want.
I have a Smithy 3 in 1 and I want variable speed.
Treadmills are often found in the FREE section of Craigslist and, well, now I have the motor from a treadmill.
It's a pretty common 130V 2.5HP motor.
I tested the motor with a variable power supply I have that only goes up to 24V. The motor is fine. I need to remove the balancer "pulley" to get a V-belt pulley on it. No problem there. I also need to find a way to mount the side-mount motor in the face-mount machine. I'll figure it out.
Here's where I'm less confident.
I'm a cheap bastard with too much free time, knowledge, and skill, to pay $100 for a speed controller. I don't want to use the speed controller from the treadmill because of it's slow start "feature". I do like that the treadmill motor controller will adjust the voltage to accommodate for load. The motor has a built in tachometer.
I watched this video (and a couple others that have the same components)
and it looks pretty easy.
There's talk about adding a capacitor to handle sparking but don't know what value to add.
Does anyone have any input? Better ideas? Any other advice that will help?
The motor is basically this: zdy082-mnt-075
