Nessmuk1 Report post Posted December 29, 2018 I want to run a DC servo motor on my 12 inch lathe. I need a 1hp motor with a knob speed control and a simple off on switch. Quote Share this post Link to post Share on other sites
DonInReno Report post Posted December 29, 2018 Surpluscenter.com usually has good deals on large non-servo dc motors and speed controls that might work, but 1 hp isn’t much for a 12” lathe. If you really are sold on a big servo they are readily available on eBay, but finding a stand alone controller set up as you described will be difficult - industrial servos are typically not a plug and play application - even a controller that can drive the servo on its own needs a lot of setup. its a better question for one of the home machinist forums.

dikman Report post Posted December 29, 2018 Are you talking about 12" between centres or 12" swing? Quote Share this post Link to post Share on other sites
Nessmuk1 Report post Posted December 29, 2018 It's a 12 x 36 lathe. I'm looking for something with torque at all speeds. It had a huge 1hp Japanese motor from the 80's on it. I'd like something lighter and quieter. Quote Share this post Link to post Share on other sites
dikman Report post Posted December 29, 2018 I agree with Don, you'd be better off finding a machinery/lathe forum. From what I've read the most common solution appears to be a 3-phase motor with a VFD. Quote Share this post Link to post Share on other sites
katit Report post Posted December 30, 2018 Yep. Thats what I did with my 9x20 HF lathe. VFD and motor. There is DYI out there how to do it and I got all controls for speed, on/off and reverse right on front of the lathe Quote Share this post Link to post Share on other sites
