Product Description:
Bosch Rexroth Indramat manufactures the MSK071E-0202-NN-S1-UG0-NPNN within its MSK IndraDyn S Synchronous Motors series. Classified as an IndraDyn S synchronous servo motor, this unit delivers closed-loop torque and velocity control for positioning axes in machine tools, packaging stations, and general factory automation cells. By combining permanent-magnet excitation with precise feedback electronics, the motor converts drive power into repeatable rotary motion required for interpolated moves and coordinated multi-axis processes.
The motor dissipates heat by natural convection, eliminating fans and allowing sealed installation without external airflow. It mounts through a B5 flange assembly, so the stator housing bolts directly to a machine wall and keeps the shaft aligned with driven mechanics. Feedback signals are exchanged over the Hiperface serial interface, enabling the controller to read absolute position data through a single cable. Inside the feedback device, an optical scale with 128 signal periods per mechanical revolution supplies fine incremental data that blends with absolute information for smooth servo regulation. Rated performance is maintained in ambient temperatures from 0–40 °C, allowing operation under standard shop-floor conditions without derating.
For ingress protection, the housing carries an IP65 rating, keeping internal parts free from dust and low-pressure water jets encountered during routine washdowns. A shaft without keys or splines, specified as a plain shaft, supports backlash-free clamping couplings. The windings use insulation system class 155 to withstand elevated copper temperatures during cyclic loading, while winding code 0202 identifies electrical values matched to IndraDrive power modules. Additional features include a rotatable 240° encoder connector that eases cable routing, optical single-turn scanning, and the absence of a holding brake for applications where mechanical stiction or drive torque secures position. The 071 motor size and E length place the unit in a mid-frame envelope suited to compact machine layouts that still need steady continuous torque.
