Product Description:

The MSK075D-0450-NN-M1-UP0-NNNN is a synchronous servo motor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. Designed for closed-loop drive systems, the motor supplies precise torque and velocity control to conveyor sections, packaging actuators, and CNC feed axes. It integrates into IndraDrive power stages through a single-cable feedback and power concept, providing a compact solution where rapid dynamic response and repeatable positioning are required in industrial automation cells. This arrangement keeps the motor suitable for installations where routing space around the axis is limited and dependable position feedback is required during continuous operation.

Heat is removed purely by natural convection, meaning the housing surface alone dissipates losses without forced airflow or liquid circuits. The encoder connector can be oriented through 240° to simplify cable routing in tight cabinets. Position data are transferred via the Hiperface interface, and the built-in optical sensor delivers 128 signal periods per mechanical revolution, giving fine incremental interpolation for servo loops. Because the scanning principle is optical, magnetic debris from adjacent machinery does not influence measurement accuracy. Standard design geometry and the D length variant provide the stator mass and winding space used for this torque class.

Beyond single-turn resolution, the encoder records up to 4,096 revolutions thanks to its multi-turn absolute capability, allowing the controller to recover position after a power cycle without a homing sequence. Mechanical coupling is handled by a shaft with a keyway, which supports secure torque transmission with rigid couplings or clamping hubs. The frame code 075 sets the flange dimensions for standard IEC mounting, while winding code 0450 indicates the turn count and conductor cross section used for the motor's electrical match with compatible drives. The unit is supplied without a holding brake, so external locking devices must secure vertical axes during shutdown.
