Product Description:

The MSK100D-0300-NN-S1-RP0-NNNN is a servomotor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. As a rotary actuator, it converts drive current from IndraDrive controllers into precise shaft motion for indexing tables, packaging lines, and other closed-loop automation axes. Its embedded feedback and standardized power connection support integration into multi-axis machines.

The motor rejects heat to ambient air through natural convection, so installation must provide unobstructed airflow rather than forced cooling ducts. Position feedback travels over the Hiperface interface, allowing differential RS-485 signals from the optical reader to the drive. The code disc provides 128 signal periods, which the drive multiplies electronically for high-resolution control at any speed. Because the scanning method is optical, there is no magnet aging that could shift the zero reference over time. The measuring system is single-turn, reporting absolute position within one revolution, which is adequate for axes that recalibrate homing each cycle. Power and brake conductors exit on the right side, simplifying cable routing in cabinets that line up multiple MSK frames with identical terminal orientation.

The motor uses frame size 100, which gives a stator outer diameter suited to mid-range torque. It also has length D, which increases stack height for additional continuous power without changing the mounting footprint. The rotor transmits torque through a shaft with keyway, a form that mates to standard pulleys and couplings without custom hubs. The winding selection marked 0300 sets the voltage constant so the motor reaches rated speed on 400 V class drives. Because the model ships without a holding brake, any static load must be secured by the drive’s torque or an external clamp when power is removed.
