Product Description:

The MSK070E-0450-NN-M1-UP0-NNNN synchronous servomotor is produced by Bosch Rexroth Indramat and belongs to the MSK IndraDyn S Synchronous Motors series. Within industrial automation systems, it supplies controlled torque and precise angular positioning for axes used in machining centers, packaging equipment, and material-handling modules. When paired with a compatible servo drive, the motor supports closed-loop motion control for accurate speed regulation and repeatable positioning during dynamic machine cycles.

This motor uses Natural convection to dissipate heat, so its housing relies on ambient airflow and surface area instead of an internal fan or liquid circuit. Frame designation 070 sets the external diameter and mounting pitch, while length code E extends the active stack to support higher continuous torque in the same basic frame family. Electrical behavior follows winding code 0450, which matches the stator winding to drive voltage and current requirements. Position feedback is transferred through a Hiperface interface, allowing communication between the encoder and the servo drive over a compact signal connection. Inside the encoder, a base resolution of 128 signal periods per mechanical revolution provides fine commutation data, and the connector can be rotated by 240° to help with cable routing.

Encoder sensing is based on Optical scanning, which provides low-jitter feedback signals even when operating temperatures change. Its Multiturn Absolute encoder design retains position information across multiple revolutions, so the control system can identify shaft position immediately after startup. Because the motor is supplied without a holding brake, vertical or suspended loads require holding force from the drive or an external mechanical device when power is removed. A shaft with keyway provides positive torque transmission to couplings, pulleys, or gear inputs and helps maintain secure mechanical engagement under reversing loads.
