Product Description:

The MSK071C-0300-NN-M1-UG0-NNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. This standard-design unit uses motor size 071 and length code C, making it suitable for medium-torque duties in packaging, handling, and forming machines. As a synchronous servo motor, it converts drive commands into precise rotary motion for axes that require repeatable speed and position control. A rotatable 240° encoder connector helps route the feedback plug in tight cabinet spaces, and the motor is supplied without a holding brake so static load retention must be provided by the drive or by an external locking device.

The motor dissipates heat through natural convection, eliminating the need for forced fans and supporting installation where simple cooling is preferred. Feedback data are transferred over the Hiperface protocol, which carries position information and electronic nameplate data between the encoder and the drive. Position sampling is based on an optical system that yields 128 signal periods per mechanical revolution, and the feedback device uses multi-turn absolute feedback so the drive can recover absolute position after power interruptions. The housing meets IP65, preventing dust ingress and resisting low-pressure water jets during normal operation.

Winding code 0300 sets the voltage constant and torque profile expected by the drive controller. The motor uses a plain shaft, allowing coupling elements to be mounted directly on the cylindrical journal without keys. Insulation class 155 supports continuous winding temperatures suited to passive cooling during normal operation. Operation is permitted at ambient temperatures from 0 to 40 °C, allowing full-duty use within that range when the motor is installed in a protected machine environment.
