Product Description:

The MSK075D-0450-NN-M1-UG1-NNNN synchronous motor is manufactured by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. It functions as a closed-loop drive element for positioning tables, packaging lines, and coordinated multi-axis systems where precise velocity and torque control are required. This type of motor is commonly used where repeatable starts, stops, and synchronized motion must remain stable under changing load conditions. Its mid-frame geometry suits medium-power tasks, and its standard mechanical outline supports straightforward installation in new systems and retrofit applications.

This model is cooled by natural convection, so heat is dissipated through the housing without external fans or liquid circuits. Size code 075 indicates the stator diameter and flange pattern, while length code D extends the active stack to increase continuous torque. Winding code 0450 identifies the copper fill and electrical resistance selected for 400 V class drive outputs. A plain shaft transmits torque directly into couplings or gear stages, and an electrically released holding brake provides 23 Nm of static torque when power is removed. A rotatable 240° motor-side connector allows flexible cable routing inside crowded cabinets, and the motor has a standard design for compatibility with common mounting accessories.

Feedback is provided by a Hiperface encoder that communicates absolute position data to the drive. Its sensing head uses an Optical scanning principle and resolves motor rotation into 128 signal periods per mechanical turn. As a Multiturn Absolute unit, it also tracks up to 4096 revolutions without battery backup, which removes the need for homing after power cycles. The encoder connector can be rotated during wiring, which helps reduce cable strain and keeps the assembly compact once the motor is mounted in the machine frame.
