Product Description:
Bosch Rexroth Indramat supplies the MSK100B-0400-NN-S1-BP1-NNNN as part of the MSK IndraDyn S Synchronous Motors series. The unit is an AC servomotor intended for closed-loop positioning and velocity tasks in automated machinery. Its compact dimensions and accurate feedback support use on machine axes where precise motion control is required. It is suited for servo applications that require repeatable acceleration, controlled speed changes, and stable positioning during cyclic machine operation.
The motor relies on natural convection to remove heat, so no external blower or liquid circuit is needed when it is mounted in free air. A housing sealed to IP65 prevents dust ingress and water-jet penetration, permitting direct installation on production equipment without a separate cabinet. Position feedback is transferred through a Hiperface interface, and this digital channel carries signals from the optical sensor head with 128 signal periods per mechanical revolution. Because the encoder is single-turn, one electrical revolution of data is available after every power cycle, which is suitable for axes that perform homing at startup. The motor has a standard mechanical design with a size 100 frame and B-length stator that match winding code 0400. A keyed shaft mates with common couplings, and the power connector is located on the B-side of the stator housing to simplify cable routing along the machine frame.
An electrically released brake supplies 32 Nm of static holding torque, allowing vertical or suspended loads to remain motionless when the drive is de-energized. The encoder uses optical scanning, giving high signal fidelity while maintaining immunity to magnetic fields that can disturb resolver systems. Continuous operation is specified within an ambient range of 0 to 40 °C, matching typical plant environments without the need for active cooling inside the cabinet. Thermal insulation class 155 (F class) allows the winding to withstand prolonged duty cycles without degrading varnish or insulation resistance.
