Product Description:

Bosch Rexroth Indramat's MSK050C-0300-NN-M1-UG0-NSNN is part of the MSK IndraDyn S Synchronous Motors series and serves as a servomotor for precise torque and position control on packaging, printing, and handling axes. It is intended for applications that require repeatable motion, accurate response during changing load conditions, and stable servo behavior through frequent start-stop cycles. Size 050 with length code C keeps the frame compact, and the design supports both standard and explosion-protected installations. The housing format helps the motor fit machinery where installation space is limited but controlled motion is still required.

Its thermal behavior is managed by natural convection, eliminating the need for forced-air devices and allowing the housing to dissipate heat directly into the surrounding air. The enclosure is rated IP65, so dust ingress is prevented and low-pressure water jets are tolerated when the cable and encoder connections are properly sealed. Position feedback is provided through a rotatable 240° connector that carries the Hiperface interface. This feedback path supplies commutation data and diagnostic information to the drive during operation. Inside the encoder, an optical scanning system produces 128 signal periods per mechanical turn, which supports fine interpolation and smooth speed control. Continuous duty is supported within an ambient range of 0 to 40 °C, matching typical control cabinet conditions.

The encoder is a multi-turn absolute device, so the controller receives shaft position over multiple revolutions without a battery-backed reference run. The mechanical output end is a plain shaft, which simplifies coupling to gearheads or pulleys without keys. The model is supplied without a holding brake, so any static load must be held by external means or continuous torque from the drive. This arrangement is common on axes where an external brake or mechanical restraint is already provided by the machine. Winding code 0300 matches the stator to compatible IndraDrive amplifiers for the correct current and voltage scaling. Thermal endurance corresponds to insulation class 155, so the varnish and winding materials can tolerate winding temperatures up to 155 °C during intermittent overloads.
