Closed-Loop Stepper Motors

CS-M Series Features

  • Frame size: NEMA11 (28mm) - NEMA34 (86mm)
  • Max. holding torque up to 12Nm
  • High-precision closed-loop control with 1,000- or 5,000-line incremental encoders
  • Strong torque performance across all speed ranges with reduced heat and vibration
  • Optional integrated brake and IP65-rated models for demanding industrial environments
  • UL-certified motors and drives ensuring global compliance and long-term reliability

As the official distributor for the UK and Ireland, Motion Control Products is proud to present the Leadshine CS-M Series closed-loop stepper motors, a cost-effective yet high-performance solution for demanding motion control applications. Designed for engineers who require accuracy, stability and operational reliability, the CS-M range delivers the benefits of servo-like performance without the complexity or cost typically associated with servo systems.

The CS-M Series is available in a wide selection of NEMA frame sizes, from compact NEMA 11 (28 mm) and NEMA 14 (35mm), through the popular NEMA 17 (42mm) and NEMA 23 (57mm/60mm) ranges, up to the powerful NEMA 34 (86 mm) with a maximum holding torque of up to 12Nm. Each motor integrates either a 1,000-line (4,000 counts/turn) or 5,000-line (20,000 counts/turn) incremental encoder, providing stable, closed-loop positional feedback and ensuring accurate and repeatable motion control.

The ES-M easy servo motors are being replaced with the CS-M motors. These CS series closed loop stepper motors are perfect match with CS series closed loop stepper drives.

 

Unlike conventional open-loop stepper systems, the CS-M Series eliminates common issues such as missed steps, motor hunting, or the need for gain tuning. This allows the motors to maintain high torque across a wide speed range, operate with significantly reduced heat, and deliver low vibration, making them ideal for precision machinery, automation equipment, 3D printing, packaging systems, and other industrial applications requiring dependable positioning control.

Optional features include integrated holding brakes and IP65 protection on selected models for enhanced environmental resistance. These additions make the CS-M Series suitable for applications exposed to dust, moisture or frequent stop-and-hold requirements.

Certified Quality for Global Markets

Both the CS-M closed-loop stepper motors and their matching drives are UL certified, providing machine builders and OEMs with the compliance and confidence needed to supply equipment to international markets. Leadshine’s large-scale automated manufacturing and stringent quality management ensure each motor offers high stability, long service life, and consistent performance, all while delivering excellent value.

The Leadshine CS-M Series represents a robust, reliable and economical solution for engineers seeking servo-like precision with the simplicity of a stepper motor system.
