WHEELTEC MS42DDCR Integrated Driver Stepper Motor

The WHEELTEC MS42DDCR is an integrated driver and controller stepper motor featuring a high-precision 1:13.8 reduction gearbox. Designed for students, educators, and makers, this compact unit simplifies wiring and delivers high torque for advanced robotics and automation projects.

Integrated drive and control

The MS42DDCR consolidates a two-phase hybrid stepper motor, a driver, a control circuit, and a high-precision encoder into a single compact unit. It supports serial, CAN, and RS485 control interfaces, significantly reducing wiring complexity in your builds.

Robust industrial design

Built on a standard NEMA 17 footprint, this motor features an industrial-grade 4-layer PCB for reliable routing and compliance. It operates on a wide 10V to 26V power supply and includes input power reverse polarity protection to safeguard your electronics.

High torque geared performance

Equipped with a 1:13.8 reduction gearbox, the MS42DDCR model delivers a rated torque of 1180 mN.m at 21 RPM and a stall torque of 3200 mN.m. It weighs 0.53 kg, features a step angle of 0.129 degrees, and achieves a control accuracy of 0.03 degrees.

Advanced feedback and cascading

The integrated 14-bit encoder is self-powered internally, requiring no extra external power supply. The board also features reserved input and parallel output interfaces, allowing multiple motors to be easily cascaded in complex multi-axis systems.
