NEMA 23 Stepper Motor (425 oz-in 1/4" dual shaft) 2.8 Amps

This is one of the highest torque NEMA 23 stepper motors for this frame size at 425 oz-in torque. This is perfect for small to medium size CNC Routers. The best driver for this motor is the 4.2A modular Driver. A good coupling for the motor from BuildYourCNC with the 1/4" shaft are these: 1/4" to 1/2" Flexible Clamp-on 1/4" to 1/2" Rigid Clamp-on 1/4" to 1/4" Rigid Clamp-on If you have an 8mm-shaft version of this motor, a good coupling is: 8mm to 1/2" Rigid Clamp-on This CNC motor is actually considered a NEMA 24 frame size, but the size is not much difference to the two frame sizes.. This stepping motor has the highest torque that we could find in the NEMA 23 size range. Wiring: Red and Blue to A+, Yellow and Black to A-, White and Brown to B+ and Orange and Green to B-.
