Product Description:

The MSK100C-0450-NN-S1-BP2-NNNN synchronous servomotor is manufactured by Bosch Rexroth Indramat and belongs to the MSK IndraDyn S Synchronous Motors series. It is an electronically commutated AC machine built to deliver precise torque and velocity control in automated machinery, assembly cells, and packaging stations. By pairing with IndraDrive controllers, the motor forms a closed-loop axis that positions loads accurately and maintains repeatable motion profiles essential for industrial automation.

Its cooling method is natural convection, so heat is dissipated through the housing without forced airflow, simplifying cabinet design and preventing dust-laden fan streams. Position feedback is delivered through a Hiperface interface that carries both absolute position and motor identification data to the drive. Inside the encoder, an optical scanning disc generates 128 signal periods per revolution, providing fine angular resolution for tight position loops. An electrically released holding brake produces 70 Nm of static torque, allowing vertical axes to remain locked when power is removed. The standard housing design, combined with a shaft that includes a keyway, matches common couplings while keeping run-out within series limits.

A single-turn encoder limits absolute position data to one mechanical revolution, which is sufficient for many rotary axes that home at startup. Stack length code C indicates the overall body depth and corresponds to the rated torque class, while frame size 100 sets the flange pilot diameter used for mounting in this motor platform. Power and feedback cables are routed on the B-side, enabling parallel mounting when drives are arranged in line. Electrical characteristics follow winding code 0450, so resistance and inductance are matched to IndraDrive inverter current limits.
