Product Description:

The MSK071E-0300-NN-S3-UG0-NPNN servomotor is produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It is intended for closed-loop drive systems where accurate speed and position control are needed in assembly cells, feeders, and gantry modules. The motor’s 071 frame and E-length stator give a balanced ratio between continuous torque and overall size, making it suitable for medium-duty axes that mount directly to a machine wall or gearhead without extra adapters. Its synchronous design also supports repeatable motion during frequent starts, stops, and position changes.

This model is cooled by natural convection, so thermal losses are dissipated through the housing rather than by forced airflow. Mechanical attachment is handled through a B5 flange assembly that keeps the rotor concentric with coupled loads. Position data travels over the Hiperface protocol, and the integrated encoder resolves motion into 16 signal periods, allowing the controller to command fine incremental moves. The housing is sealed to IP65, which helps keep dust and low-pressure water jets away from internal parts. The encoder connector can be rotated 240 degrees for cable exit flexibility, and its capacitive scanning principle resists magnetic interference. Because the encoder is single-turn, absolute position is retained for one full revolution before the controller continues with incremental tracking.

Electrical behavior is tied to winding code 0300, which indicates the coil resistance and inductance combination used with compatible IndraDrive inverters for current control. Continuous operation is permitted within an ambient range of 0–40 °C; staying within this window helps maintain the insulation system at class 155 limits. Motion is delivered through a plain shaft that mates with clamp or keyless couplings, and the design omits a holding brake, so external locking devices are needed on vertical axes when power is off. This arrangement suits installations where braking is handled elsewhere in the drive system. The shaft end can also be paired with clamping hubs that benefit from accurate concentric rotation and low backlash.
