Product Description:

The MSK061B-0300-NN-S1-UP0-NNNN servomotor is produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It is an AC permanent-magnet motor intended to act as the drive element on precision axes in industrial automation, where tight position and speed regulation are required. The unit combines a compact 061 frame with length code B, giving machine builders a moderate torque envelope without enlarging the installation footprint. Integrated optical single-turn feedback communicates shaft position to the drive so coordinated motion, interpolated moves, and rapid cycling can be executed repeatably across multi-axis systems.

Heat generated in operation is carried away by natural convection, eliminating the need for external blowers or liquid circuits and allowing installation in sealed cabinets. The housing is sealed to IP65, which prevents dust ingress and resists low-pressure water jets during equipment washdown. Position data are supplied by an optical encoder that delivers 128 signal periods per mechanical revolution; this resolution supports smooth velocity loops and fine incremental moves. The encoder communicates through the Hiperface interface, enabling digital parameter storage and electronic identification functions with Rexroth drive controllers. A rotatable 240° connector lets the feedback cable exit in different directions, simplifying cable routing in cramped enclosures.

The steel shaft is manufactured as a shaft with keyway, providing positive mechanical coupling to timing pulleys or rigid couplings without relying on friction alone. This motor can be deployed in environments between 0–40 °C without derating, aligning with typical shop-floor ambient ranges. Because it is supplied without a holding brake, external clamping or maintained drive torque is required when vertical loads need to be secured. Thermal insulation class 155 supports sustained winding temperatures associated with high-duty cycles, while winding code 0300 corresponds to the electrical constants matched to MSK drives that share the standard housing design.
