Size 57mm NEMA 23 Stepper Motor 0.7 N-m/1.2 N-m/1.8 N-m/2.5 N-m/3.0 N-m/3.5 N-m with Magnet Hole

This NEMA 23 stepper motor series (57mm frame) is available in holding torque options from 0.7 N·m (99 oz·in) up to 3.5 N·m (496 oz·in), all in a compact 57 × 57 mm frame with body lengths ranging from approximately 41 mm to 112 mm depending on the torque model. They feature a standard 1.8° step angle, 4-wire bipolar wiring, and a rated current typically between 1.0 A and 4.2 A per phase. The integrated magnet hole on the rear shaft allows for easy mounting of a magnetic encoder or provides a convenient access point for shaft adjustments. This versatile series is well suited to a wide range of precision motion control applications, including 3D printers, CNC routers and engravers, automated robotics, textile machinery, and general industrial automation systems requiring reliable, high-torque positioning. The matched drive is M542C.
