Leadshine IP65-Rated Waterproof Stepper Motor 86CM120-FS 12 N-m

This Leadshine 86CM120-FS IP65-rated waterproof stepper motor delivers 12 N·m of holding torque in a NEMA 34 frame measuring 86 × 86 mm with a 157 mm body length, featuring a 14 mm shaft diameter and weighing 5.1 kg. It operates with a 1.8° step angle, 6.0 A rated current per phase, and a 24–110 VDC/AC 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 M860D.
