Product Description:

The MSK071E-0450-NN-M1-UG1-NSNN is a synchronous servo motor built by Bosch Rexroth Indramat and assigned to the MSK IndraDyn S Synchronous Motors series. It operates as a torque and speed actuator in CNC machines, packaging lines, and other automation equipment where closed-loop motion control is required. The motor integrates with IndraDrive controllers and relies on its internal encoder feedback to maintain precise position during rapid cycles. Because the feedback system is built into the motor, the drive can monitor rotor angle directly and correct for load changes without separate external feedback hardware. That arrangement supports repeatable motion on indexing, transfer, and handling axes where quick acceleration and deceleration are common.

Heat generated in operation is removed by natural convection, so the unit can be mounted without external fans. A cast housing with a protection rating of IP65 blocks dust and low-pressure water jets, permitting installation close to the work zone. The motor has a plain shaft, allowing direct coupling with gearboxes or belt pulleys. A rated insulation class of 155 supports winding temperatures typical of continuous duty, and the motor maintains full performance in ambient air from 0–40°C. Size code 071, length code E, and winding code 0450 identify the motor's frame and winding combination for use with compatible drive systems. This cooling method keeps the enclosure simple and avoids the extra parts required for forced-air accessories. It also reduces noise by eliminating separate blower hardware.

Position feedback is delivered by an optical encoder that combines multi-turn absolute functionality with a resolution of 128 signal periods. The data stream follows the Hiperface protocol and exits through a rotatable 240° connector, simplifying cable routing in confined cabinets. An electrically released holding brake supplies 23 Nm of static torque to secure vertical loads when power is off. This encoder arrangement lets the control system retain position information across multiple revolutions and resume operation with accurate reference data after a restart. The brake also helps keep the axis stationary during standstill periods when external motion must be prevented.
