Product Description:

The MSK050C-0450-NN-M1-UG0-NNNN servomotor is produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It serves as a rotary actuator for closed-loop motion axes in industrial automation, where the drive regulates torque, speed, and position to keep machine movement consistent from cycle to cycle. Its C-length housing and size 050 stator frame give it a compact form that suits handling equipment, packaging machinery, and assembly stations. This layout makes it appropriate for medium-duty axes that need responsive motion without requiring the larger footprint of higher-frame motors.

The housing has an IP65 rating, which helps protect internal components from dust and low-pressure water jets. Rated ambient operation is 0 to 40 °C, making the motor suitable for standard industrial spaces when surrounding air can circulate normally. Rotor position is measured by an optical encoder with 128 signal periods per revolution, and the feedback signal is transmitted through the Hiperface interface so a compatible drive can process speed and position data during motion. Cooling is provided by natural convection, so heat leaves the housing without a separate fan. This cooling method keeps the motor package simple and avoids additional airflow hardware around the frame.

The output uses a plain shaft, which supports clamp-style couplings and other friction-based connections without a keyway. The encoder is a multi-turn absolute type, so the motor can retain position information after power returns instead of requiring a homing cycle on restart. A rotatable connector with a range of 240° helps route the cable in tight installations where exit direction matters. Insulation class 155 permits continuous winding temperatures up to 155 °C, and the motor is supplied without a holding brake for applications that use external load holding or other mechanical retention.
