Product Description:

The MSK100B-0400-NN-M1-AG1-NNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. The unit operates as the rotary actuator in a drive system, converting controlled stator currents into precise shaft torque and velocity. By delivering high dynamic response and repeatable positioning, it supports automated packaging equipment, metal-cutting centers, and material-handling stations where coordinated multi-axis movement is required.

Its thermal management relies on natural convection cooling, so ambient airflow alone carries heat away from the stator without external fans or liquid circuits. Feedback information is transmitted through a Hiperface interface, allowing connection to a compatible drive through a combined power and feedback cable. The built-in optical encoder generates 128 signal periods per mechanical revolution, and the optical scanning principle supports fine position detection without relying on magnetic pole spacing. In addition, the encoder is a multiturn absolute type, so the motor can report shaft position over several turns after power loss without a homing cycle. Electrical characteristics follow winding code 0400, which sets the rated voltage, current, and torque constants used when sizing the inverter.

The integrated holding brake is electrically released and can clamp the rotor with 32 Nm of static torque to secure vertical loads or maintain position during emergency stops. Power conductors enter on the motor’s A-side, simplifying cable routing when the housing is rotated so the connectors face the drive cabinet. A plain shaft without a keyway transfers torque through friction couplings or shrink discs, reducing backlash and allowing quick assembly of pulleys or couplings matched to the application. The motor has size 100 with a B length and a standard construction style.
