MS42DDCR Integrated Driver & Control Stepper Motor
Built-in driver and high-precision encoder
Product Details

Product Overview
MS42DDCR adopts the national standard 42 stepper motor dimensions, integrating the driver, controller, and high-precision encoder into the motor body. This eliminates the need for an external driver, simplifying wiring.
Supports 10-26V wide-voltage power supply and three control methods: serial port, CAN, and 485. Includes reserved input/output parallel interfaces for cascading multiple units. The version with 1:13.8 gear reducer is designed for joints and lifting mechanisms requiring high torque.
