Our 420 oz-in, 3/8" shaft, bipolar NEMA 23 motors are 4.2A/phase to take full advantage of most discrete and all-in-one NEMA 23 motor drivers.
They are also designed specifically with lower inductance for CNC applications to maintain higher torque throughout the RPM range, providing much better overall CNC machine performance when compared with many other common motors with higher torque ratings.
Our NEMA 23 motors are configured with DB9 connectors; no soldering or crimping is required, just plug them right into the drive, or if you need additional cable length, use one of our 20 AWG NEMA 23 CNC Motor Cables.
We've seen machine rapids over 1200 IPM with these motors when used with our Standard CNC machine kits and PRO CNC machine kits.
