Product Description:
The MSK100B-0400-NN-S1-BG1-NNNN servomotor is produced by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. It is an IndraDyn S synchronous servomotor that supplies commanded torque and velocity to automated machinery. The unit pairs its 100-frame stator with winding code 0400 and is typically driven by Rexroth IndraDrive amplifiers to position packaging axes, material-handling gantries, and tooling spindles.
The motor uses natural convection for heat dissipation, so the housing transfers losses directly to surrounding air without forced airflow. A protection rating of IP65 shields the stator and connector set against dust ingress and low-pressure water jets, enabling cabinet-external installation. It sustains continuous operation within an ambient envelope of 0–40 °C; beyond that range, derating is required. The frame code indicates a 100 stator and a B-length stack, giving continuous torque while preserving compact depth. Power conductors exit on the B-side connector, simplifying cable routing when the motor is bolted to the machine frame. A plain shaft is supplied for backlash-free coupling. The insulation system is rated to Class 155, and the motor uses the standard design version.
Position feedback relies on the Hiperface serial interface. An optical scanning head reads a coded disk that produces 128 signal periods per revolution and stores single-turn absolute angle data for rapid startup. Rotor locking at rest is achieved by an electrically released brake that supplies 32 Nm of holding torque to secure vertical or suspended loads when drive power is removed. The brake coil wiring is integrated into the same B-side connector used for the stator phases, reducing installation points. The feedback system and brake support controlled startup and secure load holding when the axis is at rest.
