Leadshine High Torque NEMA 23, 34 Stepper Motors For CNC, 3D Printers, Robotics & Automation Systems
Leadshine CM series 57 86 stepper motors can be implemented in many industrial motion control applications. Built with premium quality materials including bearings and shaft made by famous manufacturers, they can move the attached load at high precision and High Torque NEMA 23 & 34 Stepper Motors with very low motor heating & vibration.
Leadshine 57CM 86CM Stepper Motors is a high-performance, cost-effective stepper motor developed by Leadrive Intelligent Control using new designs, advanced processes, and imported core materials from Japan. Compared to common stepper motors on the market, it offers greater torque, lower heat generation, and improved stability during operation. Thanks to large-scale automated production lines and a strict quality management system, this series provides exceptional stability, reliability, and superior performance consistency in mass production. The 57 frame size (including D57 frame) offers a range of standard stepper motors with holding torques from 0.6 to 3.1 N•m, allowing selection based on specific application needs.
