Product Description:

The MSK050C-0300-NN-M3-UP0-NNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. In automated assembly cells, it converts controlled electrical energy into repeatable rotary motion for conveyor axes, pick-and-place gantries, and indexing tables. When paired with a compatible drive, it supports closed-loop torque and speed control so the machine can carry out fast starts, stops, and position changes with consistent accuracy.

This model relies on natural convection cooling, so heat leaves the frame without fans, which simplifies maintenance and eliminates additional airflow channels inside the cabinet. Frame size 050 and length code C set the stator dimensions, while winding code 0300 matches the coil arrangement used with medium-current drives on 400 V-class inverters. The housing has an IP65 protection rating, which blocks dust entry and resists low-pressure water jets that may be present during wash-down cycles in food or pharmaceutical plants. Safe operation is permitted within an ambient temperature range of 0–40 °C, and insulation class 155 supports winding temperatures up to 155 °C. Power is transferred through a shaft with a keyway, allowing pulleys, timing gears, or couplings to be mounted without custom machining.

Position feedback is handled by a rotatable 240° connector that carries the Hiperface serial interface to the controller, allowing the cable exit to be aligned after installation. Inside the encoder, a capacitive sensing element generates 16 signal periods per mechanical turn and records position across 4,096 revolutions through its multiturn absolute structure, so the machine starts with a valid position reference. The motor is supplied without a holding brake, so any vertical load must be secured by an external locking device when power is removed.
