Product Description:

The MSK101E-0300-NN-S1-BG2-NNNN is a synchronous servomotor produced by Bosch Rexroth Indramat in the MSK IndraDyn S Synchronous Motors series. The device converts drive current into rotational motion for linear actuators, rotary tables, and other precision axes used throughout automated assembly and processing equipment. Its role in these systems is to supply accurately regulated torque so that motion profiles generated by the controller are reproduced at the mechanical shaft without overshoot or drift. It does this by pairing a permanent-magnet rotor with high-density stator windings and an integrated feedback interface that helps save installation space while supporting closed-loop positioning.

The E-length housing uses natural convection for heat dissipation, but documentation indicates that external forced airflow is required during continuous high-load operation. Position data are returned through a Hiperface interface, and the embedded optical scanner delivers 128 signal periods per mechanical revolution. Because the sensing principle is optical and the track is single-turn, the controller receives absolute position feedback within one turn, eliminating index moves after power-up. A factory-installed brake is electrically released and provides 70 Nm of static torque to secure vertical or inertial axes whenever power is removed. Mechanical coupling is handled by a plain shaft, and the power connector is positioned on the B-side so cable routing can follow rearward or lateral cabinet layouts, while winding code 0300 matches the stator to compatible IndraDrive inverter current ranges.

The sealed design carries an IP65 protection rating, so dust ingress and water-jet exposure do not affect internal bearings or windings when the motor is mounted outside the control cabinet. Continuous operation is specified within an ambient range of 0 to 40 °C, permitting installation in typical plant environments without auxiliary heaters or chillers. Class 155 insulation supports elevated winding temperatures before thermal aging accelerates, giving the drive system additional headroom during intermittent overloads. The standard housing uses the size-101 frame, which fits medium-duty servo axes that need substantial torque in a compact footprint.
