Product Description:

Bosch Rexroth Indramat manufactures the MSK071D-0450-NN-M1-UP0-NNNN, an AC servomotor in the MSK IndraDyn S Synchronous Motors series. The unit converts commanded drive currents into precise rotary motion for indexing tables, gantry axes, and other high-performance automation stations. As part of a closed-loop drive system, it pairs with IndraDrive amplifiers to provide continuous torque and position feedback for accurate motion control.

Its cooling method relies on natural convection, so heat is removed through the housing fins rather than forced airflow. The design is standard, so the mounting dimensions and electrical interface follow the common MSK profile. For feedback, the motor uses a connector that is rotatable through 240°, so the plug can be turned to reduce cable stress in confined spaces. Inside the housing, rotor position is sensed by a Hiperface encoder. This encoder generates 128 signal periods per mechanical revolution, and after internal interpolation the drive achieves high resolution for contouring applications. Because the sensing path is optical, signal quality remains stable across temperature and vibration ranges.

The feedback module has multi-turn absolute capability, so the controller recovers position after power loss without a homing move. Mechanical power exits through a shaft with keyway, providing positive drive engagement with couplings or pulleys. The stator stack uses motor length code D, which increases continuous torque compared with shorter variants while keeping the frame diameter at size 071. The motor uses winding code 0450, which sets the resistance and inductance values expected by the matching drive. The model is supplied without a holding brake, so external locking devices are required for vertical loads, and its standard construction simplifies integration into sealed machine enclosures.
