Product Description:

The MSK100B-0400-NN-M2-BG0-RNNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. In industrial automation, it supplies closed-loop rotary motion that can be coordinated with digital drives for positioning, contouring, or constant-speed duties. The motor fits directly on mechanical loads such as gear stages or belt pulleys, providing a compact torque source for packaging, metal-cutting, and material-handling equipment where accurate velocity and repeatability are critical.

Heat is removed by natural convection, so the installation must allow free airflow around the housing instead of forced cooling hardware. The housing is sealed to IP65, which keeps dust and water jets away from the internal windings and bearings. A plain shaft is supplied for use with zero-backlash clamping hubs or shrink discs. The motor has motor size 100, which gives the stator and rotor cross-section used across the MSK range. The winding system uses thermal class 155 insulation, so it can tolerate temperatures up to 155 °C during intermittent overloads. The rotor is built with increased concentricity, which reduces radial runout and supports smooth operation at higher speeds.

For position feedback, the motor carries an EnDat2.1 optical encoder that outputs 2048 signal periods per revolution and uses a multiturn absolute counting mechanism. This interface allows drive controllers to read position, diagnostic, and motor data over the same cable, while 5 V sensor power is routed through the B-side power connector. The winding code 0400 and the B-length housing suit axes that rely on external clamping devices when power is removed because the motor is supplied without a holding brake. Operation is permitted at ambient temperatures from 0 °C to 40 °C without derating.
