Product Description:

The MSK040C-0450-NN-M1-UG0-NSNN synchronous servo motor is manufactured by Bosch Rexroth Indramat and belongs to the MSK IndraDyn S Synchronous Motors series. It is intended for use in automated machinery where a compact rotary actuator must follow precise position and velocity commands from a compatible drive controller. In service, it provides the mechanical output stage for pick-and-place modules, packaging axes, and similar motion tasks where repeatable rotary movement is required. Its C-length housing provides an intermediate motor length that supports continuous torque without requiring a large installation envelope.

Heat is dissipated by natural convection, so airflow around the frame must remain unobstructed to keep winding temperature within limits during continuous duty. Inside the housing, an optical measuring system tracks rotor position with light-based scanning that is not affected by magnetic fields. Position data are exchanged through the Hiperface serial interface, which allows the feedback channel to work directly with compatible drive electronics. The encoder generates 128 signal periods per mechanical revolution, supporting fine electronic commutation and smooth low-speed operation. Output torque is delivered through a plain shaft, which simplifies coupling to gearboxes or timing pulleys when a keyed connection is not required.

The motor is supplied without a holding brake, so static load retention must be handled by the drive or by external mechanics when the axis is stopped. Power and feedback lines exit through a rotatable 240° connector that can be turned to reduce cable stress in tight cabinets or crowded machine frames. Frame size 040 indicates the stator diameter used for this motor. Winding code 0450 indicates the electrical winding arrangement selected for medium-speed applications. This layout helps route cables away from moving parts and keeps the connection point easier to position during installation.
