Product Description:

The MSK071D-0450-NN-S1-UG1-NNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. In industrial automation, the unit supplies precisely metered torque and speed so that packaging stations, handling gantries, and processing spindles follow programmed motion profiles with minimal position error. Its compact servo design supports accurate closed-loop motion in applications that require stable speed control, repeatable positioning, and dependable response to changing loads. That operating profile suits transfer axes, indexing units, and other machines where consistent motion quality is more important than simple open-loop rotation.

The motor relies on natural convection for heat removal, eliminating the need for external blowers or liquid circuits when adequate airflow is available. A rotatable encoder connector that swivels through 240° makes routing more flexible inside cramped enclosures, and the sensor block communicates through the Hiperface protocol for simultaneous position data and parameter storage. Feedback resolution reaches 128 signal periods per mechanical revolution, and its optical scanning method provides clean edge transitions to the drive. Because the encoder is single-turn, it reports absolute position within one shaft rotation and resets after each 360° cycle. The shaft end is plain to accept clamp or collet couplings without keyways, and the motor uses a standard housing layout that matches normal MSK flange geometry.

An electrically released holding brake supplies 23 Nm of static torque so vertical or suspended loads can remain secure when power is removed. The motor uses frame size 071, which corresponds to the mounting pitch and pilot diameter used on Rexroth servo flanges. Length class D extends the active stack to increase continuous power output. The winding code 0450 sets the electrical data used by the drive for current limits and voltage scaling without exceeding thermal thresholds. This arrangement lets the drive match the motor's electrical behavior to the application while maintaining stable servo response.
