Product Description:

The MSK100C-0300-NN-M1-LP0-NNNN is a synchronous servo motor produced by Bosch Rexroth Indramat and part of the MSK IndraDyn S Synchronous Motors series. As an IndraDyn S servo motor, it converts drive-controller current into precise rotary motion for positioning tasks in automated machinery, packaging lines, and material-handling axes. The unit follows the 100 frame sizing and the C length code, placing it near the middle of the family’s torque spectrum while keeping mounting dimensions compatible with standard industrial frames.

Heat generated in the windings is released through natural convection, allowing installation without auxiliary fans when ambient airflow is sufficient. Position feedback is transmitted via the Hiperface interface, which pairs initialization data with continuous high-resolution angle values. The optical encoder resolves rotor position into 128 signal periods; in multi-turn mode it tracks up to 4096 revolutions, and its multi-turn absolute design removes the need for homing after power cycles. The motor is shipped without a holding brake, so external locking or sustained drive torque must secure the load when power is removed. Winding code 0300 identifies the stator’s resistance and inductance values, allowing matched Rexroth drives to deliver rated current without saturation.

The cast housing provides an IP65 protection rating, shielding internal parts from dust and low-pressure water jets on factory floors. Continuous duty is permitted within an ambient span of 0 to 40 °C; outside this range, derating or additional cooling is required. Mechanical power exits through a shaft with a keyway, which is compatible with standard couplings, pulleys, and gearboxes. A left-side power connector simplifies cable routing, and the standard design variant shares mounting holes with earlier Rexroth models. The insulation system meets thermal class 155, allowing winding temperatures up to 155 °C before accelerated aging occurs.
