Leadshine Size 57mm Stepper Motor 57CM06 57CM13 57CM23 57CM26

This Leadshine 57 mm (NEMA 23) 2-phase hybrid stepper motor series includes the 57CM06, 57CM13, 57CM23, and 57CM26 models, offering holding torque options of 0.6 N·m (85 oz·in), 1.3 N·m (184 oz·in), 2.3 N·m (326 oz·in), and 2.6 N·m (368 oz·in) respectively within a standard 57 × 57 mm frame. Body lengths scale with torque at 41 mm, 55 mm, 76 mm, and 85 mm, while all models share a precise 1.8° step angle, 4-wire bipolar wiring, Class B insulation, IP54 protection, and rated phase currents of 3.0 A (57CM06) up to 5.0 A (57CM23/57CM26), with shaft diameters of Φ6.35 mm for the lower-torque models and Φ8 mm for the higher-torque versions. Designed for smooth, low-vibration operation and typically driven by a 20–50 VDC digital driver such as the matched M556C, this scalable series is well suited to precision motion axes in CNC routers and engraving machines, laser processing equipment, automated production lines, packaging machinery, and general industrial automation requiring reliable open-loop positioning under varying load demands. The matched drive is M556C. Please specify the model number in the order note.
