Product Description:

The MSK070E-0450-NN-M3-UG1-NNNN synchronous servomotor is produced by Bosch Rexroth Indramat and belongs to the MSK IndraDyn S Synchronous Motors series. As an IndraDyn S servomotor, it converts electrical energy into precise rotary motion for positioning, velocity, and torque control tasks within automated machinery and production cells. Its compact frame, coupled with the series' standardized mechanical interface, allows direct mounting to gear stages or load shafts without additional adapters inside compact industrial equipment. The compact housing also supports installation in tightly spaced machine layouts.

Thermal management relies on natural convection, so heat leaves the housing through ambient airflow instead of forced cooling devices. An electrically released holding brake supplies 23 Nm of static torque to secure the axis during power-off states. The motor housing is sealed to IP65 to block dust ingress and low-pressure water jets, permitting installation on open machine frames. Motion feedback is handled through a rotatable 240° connector that links to a Hiperface interface. Inside the encoder module, a capacitive scanning system generates 16 signal periods per revolution, supporting high-resolution position loops in the drive controller.

The encoder uses multiturn absolute feedback, letting controllers recover position after emergency stops without homing cycles. The mechanical interface uses a plain shaft for backlash-free coupling when matched with clamping hubs. Rated operation is specified for 0–40 °C, aligning with factory environments that include electrical cabinets or overhead gantries. Size 070 mechanics, motor length code E, and the standard design simplify interchange across the family, while winding code 0450 assigns electrical constants for compatible drives. A thermal class 155 (F) insulation system permits continuous duty without coil degradation during normal operation.
