Nema 23 Stepper Motor 3Nm(425oz.in) 4.2A 113mm 10mm Shaft for CNC Router Mill

About this item

This is a NEMA 23 bipolar stepper motor (model 23HE45-4204S) built for CNC routers, mills and other precision motion projects. It delivers 3.0Nm (425oz.in) of holding torque at 4.2A per phase, with a 1.8° step angle for smooth, accurate positioning. The motor has a 10mm shaft with a 20mm D-cut flat, a 113mm body length, and runs on 24V or 48V DC through a 4-wire bipolar setup. Class B insulation keeps it stable under continuous use up to 130°C (266°F).
