Product Description:

The MSK071E-0200-FN-S1-UG0-NNNN is a synchronous servomotor from Bosch Rexroth Indramat and belongs to the MSK IndraDyn S Synchronous Motors series. It is intended for positioning and speed-controlled axes in industrial automation cells, machining centers, and transfer systems. The motor converts electrical energy into controlled rotary motion, allowing a matched drive to regulate torque, speed, and position with high accuracy. This operating role suits servo applications that need repeatable motion during frequent start-stop cycles.

This motor uses liquid cooling, so heat from the stator is removed through an internal coolant circuit and continuous torque can be sustained without external airflow. The housing has an IP65 rating, which keeps out dust and resists water jets during normal industrial use. A plain shaft supports direct coupling to gearboxes or machine loads, and the mechanical end is supplied without a holding brake to keep mass and inertia low when static holding is not required. Parked load retention must therefore be provided by the drive or by external mechanics. Electrical terminations follow the standard design, and the feedback plug is 240° rotatable to support cable routing in confined cabinets. Drive electronics read position data over the Hiperface serial interface, allowing high-resolution feedback with digital parameter storage.

Within the encoder, the optical scale provides 128 signal periods per revolution and operates in single-turn mode, so absolute position is tracked over one mechanical turn. The stator winding uses code 0200, and the laminated core corresponds to motor size 071 with length E to balance torque density and overall weight. This longer housing within the frame helps support higher torque than shorter versions in the same motor size. Safe operation is specified for ambient temperatures from 0–40 °C, and the insulation system is certified to Class 155, allowing winding temperatures up to 155 °C before thermal aging accelerates. A liquid channel molded into the stator jacket connects directly to plant chillers for steady heat removal across changing duty cycles.
