Product Description:

The MSK071C-0300-NN-S3-UG0-NNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. This standard-design unit delivers closed-loop rotary motion for positioning tasks in industrial automation where precise velocity and torque control are required. When paired with a compatible drive, it supports accurate positioning, stable speed regulation, and repeatable axis movement in automated equipment. This makes the motor suitable for indexing axes, feed mechanisms, and other motion systems that require controlled acceleration and steady low-speed operation.

This motor relies on natural convection to remove heat from the stator, so additional fans or liquid channels are not needed in typical installations. The motor has an IP65 rating, which helps protect the housing against dust ingress and low-pressure water jets in packaging lines or machine tools. The winding code 0300 identifies the electrical layout used for this motor version within the MSK family. Thermal endurance is supported by insulation class 155, and operation is specified for ambient temperatures from 0 to 40 °C. The encoder delivers 16 signal periods per mechanical revolution, providing feedback that supports smooth speed regulation even at very low shaft velocities.

The feedback system connects through a rotatable 240° plug, uses the Hiperface protocol, and is based on a capacitive scanning method that resists magnetic interference while supplying single-turn position data. Power is transmitted through a plain shaft, which simplifies coupling to gearboxes or belt pulleys when zero-backlash clamping hubs are used. The feedback connection can be oriented to match the available cable path, which helps reduce strain where space around the motor is limited. For applications that hold load position mechanically or through drive torque, the motor is supplied without a holding brake, which removes brake control wiring and shortens the overall assembly. Motor size 071 and length code C indicate the frame dimensions.
