Product Description:

The MSK050B-0300-NN-M1-UG1-NNNN is a servo motor produced by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. Designed for precision motion tasks in industrial automation, the unit combines a compact 050 frame with a B-length stator to deliver accurate torque and velocity control to packaging machinery, assembly robots, and material-handling axes. Its electromechanical layout works with IndraDrive controllers to support closed-loop control with quick correction of load changes during acceleration, deceleration, and positioning. The passive cooling concept also suits sealed machine enclosures where forced ventilation is impractical.

The motor relies on natural convection to remove heat from its windings, so cabinet airflow must remain unobstructed during installation. Position data are transferred over the Hiperface interface, and the feedback plug is rotatable through 240°, which helps with cable routing in confined spaces. The sensing element uses an optical principle and resolves 128 signal periods, allowing the drive to interpolate fine incremental counts for smooth speed regulation and stable low-speed motion. A standard housing geometry supports consistent mounting while providing enough exterior surface area for passive heat dissipation.

Long-term accuracy is supported by the multi-turn absolute encoder function, which stores absolute position across power cycles without auxiliary batteries. During power-off states, an electrically released brake supplies 6 Nm of holding torque to secure suspended or vertical loads. Output torque is transmitted through a plain shaft, allowing direct coupling to precision gearheads, pulleys, or clamp-style hubs without keyway play. Electrical characteristics are set by winding code 0300, which matches the motor to compatible IndraDrive power modules and sets its nominal voltage, current, and torque constants.
