Product Description:

The MSK071E-0450-NN-S1-UP2-NNNN is an IndraDyn S synchronous servomotor from Bosch Rexroth Indramat in the MSK IndraDyn S Synchronous Motors series. In automated handling stations and packaging lines, it converts drive controller current into precise mechanical rotation so axes can be positioned quickly and repeatably. The motor is intended for servo-controlled motion where short moves, rapid direction changes, and stable positioning are required during continuous machine operation. Its standard housing geometry and winding code 0450 support use in compact servo-axis layouts.

Thermal management is based on natural convection, so the frame releases heat to the surrounding air without built-in fans. Because cooling is passive, the motor depends on surrounding airflow and unobstructed installation space rather than integrated ventilation hardware. Motion feedback uses a rotatable 240° connector and a Hiperface interface that carries commutation and position data to the drive, which helps cable routing in confined machine frames. Inside the encoder, an optical sensing system resolves the code disc into 128 signal periods for position capture. The feedback system is a singleturn design, so it reports position within one mechanical revolution.

An electromechanically released holding brake provides 30 Nm of torque to secure static loads when power is removed. This brake is useful on vertical or suspended axes where the load must remain in place at standstill. Torque is transmitted through a shaft with keyway, which supports positive coupling to pulleys, belts, and rigid hubs. The motor uses size 071 with the elongated E length, giving more winding space for higher continuous power while keeping the same frame diameter. That format can help when machine space is limited radially but more axial length is acceptable.
