Product Description:

The MSK101C-0450-NN-M1-BG0-NNNN is a synchronous servomotor produced by Bosch Rexroth Indramat and assigned to the MSK IndraDyn S Synchronous Motors series. Within an automation cell, this motor pairs with a compatible drive controller to deliver accurate speed and torque regulation for indexing tables, gantry axes, and other motion tasks that demand repeatable positioning. Its electromagnetic layout supports rapid acceleration and deceleration typical of high-cycle packaging lines. The motor is suited to closed-loop applications where stable response and consistent rotor control are needed throughout changing load conditions. That operating profile makes it appropriate for transfer systems and servo-driven handling equipment that repeatedly reverse direction during short motion cycles.

This model uses natural convection cooling, so heat is released directly through the aluminum frame without fans or coolant circuits. The housing carries an IP65 rating that helps protect internal laminations from dust and low-pressure water jets in production areas. Feedback is provided by an optical encoder that transmits over the Hiperface interface, and the signal resolution of 128 signal periods per mechanical revolution gives the drive precise incremental data for commutation. Because the device uses a multi-turn absolute system, it also stores the revolution count and can return position data after power is restored without a separate homing cycle.

The rotor ends in a plain shaft, allowing torque transfer through clamp-style or other keyless hubs. Power conductors are routed on the B-side to keep motor power wiring separated from the feedback connection. This arrangement helps maintain compact cable routing on machines where connector clearance is limited. Electrical characteristics are set by winding code 0450, which matches the current and voltage values expected by compatible Rexroth drive settings. Insulation class 155 supports continuous operation at elevated winding temperatures, provided the ambient range remains within 0 to 40 °C. The frame uses size 101 with length C, and the motor is supplied without a holding brake, so external locking is required when the load must remain fixed during shutdown.
