Product Description:

The MSK103B-0300-NN-M1-UG0-NNNN synchronous servomotor is produced by Bosch Rexroth Indramat and belongs to the MSK IndraDyn S Synchronous Motors series. Within an automation cell, this motor converts drive controller power into controlled torque and speed so that indexing tables, gantry axes, and conveyor sections can follow programmed motion profiles with minimal error. Its synchronous design supports precise axis movement during positioning, transfer, and feed tasks where the drive must maintain stable speed under changing load conditions.

This model uses natural convection, so heat leaves the frame without fans or liquid circuits, which helps in sealed cabinets and other low-maintenance installations. The housing has an IP65 rating that blocks dust ingress and low-pressure water jets during washdown cycles. Continuous service is allowed between 0–40 °C, which suits common indoor machine environments. Position feedback travels over the Hiperface interface, and this bidirectional channel carries encoder data and stored motor data through a rotatable 240° connector that helps simplify cable routing. Inside the housing, an optical sensor generates 128 signal periods per mechanical revolution for smooth speed regulation and accurate commutation.

The encoder also records position with a multi-turn absolute measuring method, so the control system can recover shaft position after power returns without a homing cycle. A plain shaft simplifies coupling to pulleys or precision gearboxes when a keyed connection is not required. The stator uses winding code 0300, which matches the motor’s electrical behavior to compatible IndraDrive power sections in the intended current range. Thermal insulation class 155 allows winding hot-spot temperatures up to 155 °C while preserving insulation performance during continuous operation.
