DC motor for my lathe has low torque

<< < (5/5)

vtsteam:
Thanks mc, the new controller is rated at 130V, and 18 amps I believe. It's an M60.

vtsteam:
The M60 DC controller board arrived today, along with a choke that was part of the original installation in a treadmill. The choke goes in series with the motor.

I installed the new parts temporarily using jumpers on the new lathe, and then finished a project I had already started: turning the hot piston iron casting for the engine I'm building. That gave me an immediate and direct comparison between to old controller and the new.

The difference was gratifying!  :ddb:   The motor was much smoother and quieter, it it was able to run at an even slower minimum speed than it had with the other controller. And it had much better torque at low turning speeds. I may not need a countershaft, after all, though I'll know better after I've done a variety of work with the new controller. All around a great result, and I'm very glad it was worth the purchase! I was worried it wasn't going to make much of a difference.
