Product Description:

The MSK071C-0450-NN-M1-UP0-NSNN is a synchronous servo motor produced by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. The unit is intended for closed-loop motion axes where precise torque and speed control are required. It allows machine builders to place high-density rotary power on compact mechanical stages used in automated assembly, packaging, and material-handling lines.

Heat generated by the stator windings is removed through natural convection, so the motor housing serves as the thermal path and no forced-air or liquid cooling auxiliaries are needed. Position feedback is delivered through a Hiperface interface that transmits absolute data and incremental tracks to the drive. Inside the optical sensor, scale subdivision reaches 128 signal periods, which supports fine commutation angle calculation. The encoder stores mechanical revolution information in a multiturn absolute format, eliminating homing cycles after power loss. Mechanical output is provided through a shaft with a keyway, which supports positive torque transmission and simplifies coupling alignment with gears, pulleys, or direct-drive load elements.

The motor carries the Standard and Explosion Protection design code. Electrical and feedback plugs are mounted on a rotatable, 240° connection block, allowing the cabling direction to be adjusted for tight installation spaces without sharp bending. With frame designation 071 and length code C, the device provides a balance between peak torque capability and inertia for mid-range axes. Its electromagnetic profile is identified by winding code 0450, which sets the voltage constant and rated current used to match the motor with a suitable drive controller. The unit is supplied without a holding brake, so external load-holding methods may be required when power is removed.
