Product Description:

The MSK050C-0300-NN-S1-UP0-NSNN is a synchronous motor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It serves as a compact rotary actuator that pairs with IndraDrive controllers to move axes that require accurate torque and speed regulation in industrial automation. This makes it suitable for compact servo applications such as indexing units, transfer axes, and handling equipment where stable motion control is needed. The motor has a 050 frame and a C-length housing, which fit machines where installation depth is limited. It is supplied in a standard build and is suitable for designated explosion protection zones.

The motor dissipates heat through natural convection, so airflow around the housing must be maintained instead of using forced fans or liquid cooling. Electrical connections use a single power and feedback plug with a rotatable 240° connector, which eases cable routing in crowded cabinets. This arrangement helps reduce cable strain when the motor is mounted close to machine panels or protective covers. Position data are generated through a Hiperface interface, and the internal scale provides 128 signal periods per mechanical revolution. Because the measuring system is an optical encoder, the motor supports stable repeatability during repetitive pick-and-place or indexing cycles.

Encoder tracking is limited to one revolution, so the feedback is single-turn and is suited to applications that do not require multi-turn position retention. This arrangement is common on axes where the machine establishes a reference point during normal operation. The unit is supplied without a holding brake, so position retention during power loss must be provided by drive torque or an external clamping device. Mechanical power is transferred through a shaft with keyway, providing positive engagement to pulleys or couplings. That combination is useful where a secure mechanical connection is preferred over a plain shaft. The motor uses winding code 0300, which matches its resistance and inductance values to compatible IndraDrive amplifiers for moderate continuous current and short peak-torque bursts.
