Product Description:

The MSK071D-0300-NN-S1-UG0-NSNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. The unit converts drive controller output into precise rotary motion for indexing tables, gantry axes, and other tightly regulated positions found in automated production. Its integrated feedback system allows the connected drive to maintain accurate speed and position control during repeated machine cycles.

Heat is removed by natural convection, so the motor relies on ambient airflow rather than a forced-air blower. The enclosure carries an IP65 rating that blocks dust ingress and low-pressure water jets, supporting deployment on open machine frames. Reliable operation is specified between 0–40 °C, and class 155 insulation allows winding temperatures up to 155 °C without premature insulation breakdown. With a motor size 071 frame and length code D, the stator provides the torque density expected of medium-torque axes, while winding code 0300 aligns the electrical constants with IndraDrive supply modules. The design is approved for standard and explosion-protected zones. It uses a plain shaft for coupling versatility and is supplied without a holding brake, so external locking devices must secure vertical loads when power is removed.

Position and velocity feedback are generated by an optical encoder that offers 128 signal periods per revolution. Communication with the drive occurs over the Hiperface protocol, and the feedback connector can be rotated through a 240° range to orient cabling toward the control cabinet. Because the encoder is of single-turn construction, it retains absolute position within one mechanical turn, ensuring immediate commutation after power-up while still requiring a reference move after multi-turn travel.
