Product Description:

The MSK075D-0450-NN-M2-UG1-RNNN belongs to the MSK IndraDyn S Synchronous Motors series from Bosch Rexroth Indramat. As a synchronous servomotor, it provides closed-loop torque and position control for axes that require repeatable accuracy in packaging lines, pick-and-place gantries, and CNC feed drives. The motor combines a size 075 stator with a length D iron stack to deliver continuous output in a compact housing. This format fits transfer units, indexing tables, and robotic handling axes where installation space is limited. It is intended for motion systems that need stable torque response and repeatable positioning over frequent cycles.

The unit is cooled by natural convection, so heat is dissipated through the housing fins without forced airflow. Feedback is provided through an EnDat 2.1 digital interface that sends absolute position data to compatible drives over a single high-speed pair. Inside the encoder, an optical disk delivers 2048 signal periods per mechanical revolution, which supports fine interpolation and smooth velocity control. The feedback connector is rotatable 240°, allowing the cable exit to be adjusted after mounting to reduce strain in tight panels. Position reference is retained over multiple revolutions through a multi-turn absolute scanning principle, so the axis can report position again after power is restored.

An electrically released brake supplies 23 Nm of static holding torque, which helps keep vertical axes in place when drive power is removed. Torque is transferred through a plain shaft that mates with common clamp or coupling hubs and avoids keyway stress concentrations. The rotor and flange are machined for increased concentricity, reducing radial runout and supporting stable alignment during reversing motion. Stator winding code 0450 indicates the electrical and thermal characteristics used with matching IndraDrive controllers. It is suitable for positioning tasks with repeated starts, stops, and direction changes.
