Product Description:

The MSK076C-0450-NN-S3-UP0-NNNN is a synchronous servomotor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. This C-length, size 076 unit converts electrical power into precisely controlled mechanical torque for axes that require accurate speed and position regulation in automated machinery. It belongs to the standard design group and pairs with IndraDrive amplifiers through a rotatable 240° encoder connector, which helps support compact machine layouts. The motor is suited for servo applications where repeatable motion and responsive control are required during continuous machine operation.

Heat is removed exclusively through natural convection, so the motor can be mounted without external fans if airflow around the housing is adequate. Feedback is transmitted over the Hiperface interface, and the encoder uses a capacitive scanning element with a resolution of 16 signal periods for commutation and stable low-speed control. The enclosure carries a protection rating of IP65, which resists dust ingress and low-pressure water jets when all mating connectors are properly sealed. With winding code 0450, the stator is matched for medium-torque operation, and the longer stator stack provides more active iron volume than shorter motors in the same series.

The encoder operates in a single-turn configuration, supplying absolute shaft position within one revolution for axes that reference at power-up. Torque is delivered through a shaft with keyway, which allows direct coupling to pulleys or gearboxes. Continuous service is supported in ambient temperatures from 0 to 40 °C, and the class 155 insulation system helps the winding withstand thermal stress during cyclic duty. The motor is supplied without a holding brake, so inactive loads must be secured by mechanical locking or drive-generated torque.
