Product Description:
The MSK050C-0300-NN-M1-UP0-NNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat in the MSK IndraDyn S Synchronous Motors series. Designed for closed-loop axis duties in packaging machines, printing modules, and general motion platforms, this motor converts drive inverter commands into precise rotary motion while maintaining position feedback for the controller. Its compact frame supports integration in cabinets or on-machine assemblies where servo accuracy, quick acceleration, and low maintenance are required. In a matched servo system, the motor helps the drive regulate speed, torque, and position as load conditions change during continuous machine operation.
Cooling relies on natural convection, so airflow around the housing must remain unobstructed during operation. The frame size is 050 with C length, giving an intermediate stator stack that balances torque output with compact dimensions. Torque is transmitted through a shaft with a keyway, which allows direct coupling to pulleys or gearboxes without extra shaft adapters. The winding code 0300 identifies the electrical winding used with compatible MSK drive inverters. Because the motor is supplied without a holding brake, any static load must be secured by external clamping or by the drive’s holding torque. All electrical terminations provide IP54 sealing when the mating connectors are installed.
Position reporting is handled by an optical encoder that delivers 128 signal periods per revolution and stores travel history in a multi-turn counter. Communication to the drive controller occurs through the Hiperface protocol, and the feedback lines are routed through a 240° rotatable connector that simplifies cable exit direction inside tight enclosures. The encoder is a multi-turn absolute type, so the axis can power up with immediate position knowledge instead of running a reference move. This arrangement helps the controller track shaft angle and revolution count during repeated indexing, positioning, and speed-controlled movement.
