Product Description:

The MSK101D-0450-NN-S3-AG0-NNNN servo motor is produced by Bosch Rexroth Indramat and belongs to the MSK IndraDyn S Synchronous Motors series. This IndraDyn S synchronous servo motor has motor size 101 and length code D, placing it in the upper-middle portion of the family’s torque and inertia range. Within an automated station, it supplies closed-loop rotary drive power to gantries, indexing tables, and forming equipment where precise velocity and position control are required. Its standard mechanical design and a power connector on the A-side simplify cabinet wiring. That role suits production equipment that must repeat short moves and maintain stable motion under changing loads.

Cooling is provided by natural convection, so the motor dissipates heat through its housing without external fans or liquid circuits. Position feedback uses a Hiperface interface that exchanges absolute position and motor data with the drive over two bidirectional conductors. The integrated encoder generates 16 signal periods per mechanical revolution, and internal interpolation supports fine commutation and stable low-speed operation. Because the sensing element employs capacitive technology, it maintains accuracy in environments where oil mist or magnetic debris could disturb optical or magnetic systems. The feedback is single-turn, giving an absolute reference within one revolution while relying on drive counting for motion beyond that angle.

The actuator is supplied without a holding brake, so stationary loads must be secured by the drive or an external locking mechanism. A protection rating of IP65 seals the housing against dust and directed water, letting the motor operate on open machine frames within the permitted ambient range of 0 to 40 °C. A plain shaft transfers torque directly to couplings or belt pulleys without keyways or serrations, which helps reduce runout at the shaft connection. Thermal endurance follows insulation class 155, and winding code 0450 indicates the stator resistance and inductance values used by the controller for current limiting and field-oriented control.
