Product Description:

The MSK076C-0300-NN-S1-UG0-NSNN is a synchronous servo motor produced by Bosch Rexroth Indramat in the MSK IndraDyn S Synchronous Motors series. It operates as an electromechanical actuator for closed-loop motion axes in packaging, printing, and general factory automation, where accurate torque and velocity regulation are required during synchronized machine movement. The motor integrates with IndraDrive converters and serves as a compact drive element that can couple directly to loads where low backlash and responsive motion are important.

Cooled by natural convection, the unit removes heat through its housing surface and therefore requires no external fan or liquid circuit. Position feedback is provided by an integrated encoder, and a rotatable 240° connector helps route cables in confined panels. The encoder uses the Hiperface interface, provides 128 signal periods of base resolution, uses optical scanning, and is built in a single-turn format, enabling precise absolute position data within one mechanical revolution. This arrangement supports accurate startup positioning and stable closed-loop operation. An enclosure rating of IP65 seals the frame against dust ingress and low-pressure water jets, supporting installation on open machine frames.

The drive side uses a plain shaft, so couplings or pulleys can mount without a keyway and vibration can be reduced at high speed. The motor operates in ambient temperatures from 0 to 40 °C and uses insulation class 155, allowing continuous current without conductor breakdown under normal operating conditions. The stator uses winding code 0300, and the C motor length with size 076 gives power density suited to medium-torque axes. The motor is supplied without a holding brake, so vertical loads must be secured externally when the axis is at a standstill.
