Leadshine IP65-Rated Waterproof Stepper Motor 57CM23-FS 2.3 N-m

This Leadshine 57CM23-FS IP65-rated waterproof stepper motor delivers 2.3 N·m of holding torque in a NEMA 23 frame measuring 57 × 57 mm with a 90 mm body length, featuring a 8 mm shaft diameter and weighing 1.0 kg. It operates with a 1.8° step angle, 3.0 A rated current per phase, and a 24–48 VDC driving voltage, wired 4-lead bipolar with color-coded leads (Yellow/Green for Phase A, Red/Black for Phase B). The IP65 protection rating—achieved through sealed end caps, waterproof connectors, and a shaft oil seal—makes it suitable for wet, outdoor, and splash-prone environments. Its high torque, low heat generation, and smooth, low-vibration operation make it well suited to CNC routers and engravers, laser processing machines, medical equipment, electronic manufacturing equipment, automated production lines, lithium battery production equipment, and textile machinery, as well as general industrial motion control applications requiring reliable positioning under demanding or humid conditions. The matched drive is M542C.
