Re: [CAD_CAM_EDM_DRO] nema 34 motors on BP series 1 conversion

Jon,

Someone said they are rated @ 2 amps continuous making them like 176 oz-in. The 10 amps is stall. But they can't be expected to perform at stall torque. Not for very long anyway.

Quoting from the ad :

Torque Constant, kt = 5.5 lb-In/Amp WOW!

_That's PER Amp of motor current._

At just 10 amps, that's 55 Lb-In = 880 Oz-In.

So, the question is what the peak current limit is, 10A or 20!
