Product Description:

The MSK071C-0450-NN-M1-UP2-NNNN is a synchronous servo motor from Bosch Rexroth Indramat in the MSK IndraDyn S Synchronous Motors series. Designed for closed-loop control of rotary axes, it converts drive current into torque and speed for positioning tables, pick-and-place heads, and packaging machinery. Its integrated feedback and mechanical interface allow direct connection to IndraDrive amplifiers. This arrangement lets the drive regulate speed and position directly from motor feedback, which supports accurate axis response during repeated cycles.

The motor uses natural convection for cooling, so free airflow around the housing should be maintained during operation. A protection rating of IP65 helps keep dust and low-pressure water jets away from the stator and connection areas. Signal exchange with the drive takes place over the Hiperface protocol through an optical encoder that provides 128 signal periods per revolution. The encoder has multi-turn absolute feedback, so the controller retains shaft position information after a power interruption. A rotatable 240° encoder connector helps with cable routing in tight spaces. An electrically released holding brake provides 30 Nm of static torque to help prevent unwanted movement when power is removed.

Thermal endurance is supported by insulation class 155. Continuous operation is permitted in ambient temperatures from 0 to 40 °C without derating. The motor uses winding code 0450, which matches the electrical layout for the 071 frame with length C and supports the intended drive pairing. It also has a keyed shaft for positive torque transmission, and the connector can be rotated to the required cable direction before it is clamped in place. The keyed shaft is useful where couplings or transmission elements require a fixed mechanical lock instead of a smooth shaft interface.
