Leadshine Size 86mm Stepper Motor 86CM35 86CM45 86CM80 86CM85 86CM120

This Leadshine 86mm (NEMA 34) hybrid stepper motor series includes models 86CM35, 86CM45, 86CM80, 86CM85, and 86CM120, with holding torque ranging from 3.5 N·m up to 12 N·m in a standard 86 × 86 mm frame. All models share a precise 1.8° step angle, rated currents of 4–6 A per phase, and shaft diameters of 12.7–14 mm, with IP40 protection and Class B insulation for reliable industrial operation. Featuring low heat generation, low vibration, and stable performance, this series is well suited to demanding motion axes in CNC routers and engraving machines, laser processing equipment, automated production lines, robotics, and general industrial automation requiring high torque and precise open-loop positioning. The matched drive is M860D. Please specify the model number in the order note.
