Price: $36.00 USD

See Product
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 A good coupling for the motor from Amazon with the 8mm shaft are these: 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-. Datasheet for wiring and electrical specifications Note: Datasheet contains a discrepancy: the diameter of the shaft is 1/4" or 6.35mm

  • I ordered two NEMA 23 steppers with 1/4" shafts, I received motors with 8mm shafts. I also ordered two 1/4" x 1/2" couplers, which I have not received. I have no problems with the motors, but I will need couplers to match the 8mm shaft to 1/2" lead screw.

    I will send two 8mm to 1/2" couplings to you ASAP. Please send an email to customerservice@buildyourcnc.com so I can determine to whom to send the couings. Thanks. Additional Information: Please notice, I followed up with several emails abut this situation. In one, I corrected the motor shaft sizes to 10mm. I understand that, as a result of my emails, the original 1/4" x 1/2" couplers were sent and apparently received by someone at the wrong address. As of this time, I have received no couplers of any size and have gotten no reponses to my emails. Can you enlighten me? Additional Information: I looked all throughout my email and I cannot find an email from you. Please send an email to phooddaniel@gmail.com so I can determine who this is and to whom I need to send the new couplings. Thanks

  • There are 8 wires on this motor. How do you connect to the driver?

    If the motor has 8 wires, you will need to wire the stepper motor in bipolar parallel. This motor (425 oz-in) is wired as follows: Red and Blue wires to A+ on driver Yellow and Black wires to A- on driver White and Brown wires to B+ on driver Orange and Green wires to B- on driver

  • I have two of these motors, both purchased recently as part of the heavy gantry 3-axis combo. They are warm to the touch when not doing anything. Is this normal? They work when jogged w/mach4

    It is normal for stepper motors to get hot to the touch while not moving. There is a setting on the driver that you can set to half current. This is an idle current while the motor is just in a holding position.
