Product Description:

The MSK071D-0450-NN-S2-UG1-RNNN is an IndraDyn S synchronous servo motor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. In an automation cell, it converts drive-controller current into accurately timed rotary motion for positioning tables, feed axes, and packaging stations that require rapid acceleration and repeatable accuracy. Its permanent-magnet design supports precise speed and position control, helping the axis maintain stable motion during indexing, feeding, and short-cycle positioning tasks. The motor is intended for closed-loop operation with a compatible drive, where commanded torque and rotor feedback are continuously matched during machine movement.

Heat is removed by natural convection, so the motor can be mounted in closed machines without auxiliary blowers. A housing rating of IP65 protects the stator against dust and water jets commonly encountered on machining and food-processing lines. For feedback, an optical encoder with EnDat 2.1 communication provides 2048 signal periods, supporting high-resolution commutation and position control, and the encoder connector can be turned to ease cable routing in tight spaces. The motor uses winding code 0450, and its class 155 insulation system allows the windings to tolerate elevated temperatures during cyclic duty.

An electrically released holding brake supplies 23 Nm of static torque to secure vertical or suspended loads when power is removed. This brake is intended for holding at standstill rather than for dynamic stopping during motion. The motor operates in ambient temperatures from 0 to 40 °C without derating under normal installation conditions. Feedback is limited to single-turn operation, which suits axes that reference at startup while still providing absolute position within one mechanical revolution. The motor has a plain output shaft and frame size 071 with length D geometry, allowing direct connection to couplings or timing belts without requiring a keyed shaft.
