Product Description:

The MSK071E-0300-NN-S1-UP2-NNNN is an IndraDyn S synchronous servo motor built by Bosch Rexroth Indramat and part of the MSK IndraDyn S Synchronous Motors series. It is intended for automation axes that need closed-loop torque and velocity control, especially where repeatable motion is important. The motor fits compact machine layouts because its housing supports a small installation envelope without sacrificing the controlled response expected from a servo axis. When used with a compatible drive, it helps maintain stable speed and accurate response during repeated cycles.

This model uses natural convection for cooling, but the FN code indicates that an external airflow path is required when ambient temperature rises. The housing uses the standard design, while the 071 frame size and E length balance torque density with a moderate footprint. An integrated holding brake resists back-driving when power is removed, and its static capacity is 30 Nm. That brake supports axes where the load must not drift at standstill. Winding code 0300 identifies the electrical characteristics assigned to this motor size. For feedback, the built-in encoder provides 128 signal periods, giving the drive fine incremental information during small-angle motion and low-speed correction.

The feedback system communicates through the Hiperface interface and uses an optical scanning method to read rotor position. Because the encoder is a single-turn device, it reports absolute position within one revolution without battery support. The connector can be rotated through 240°, which helps route cables in confined cabinets and reduces strain from tight bend directions. The motor uses a shaft with keyway for secure torque transmission to couplings or other driven components. A rotatable connector can simplify mounting when the motor is installed near guards, panels, or neighboring axes.
