Product Description:

The MSK075D-0450-NN-M2-UP0-RNNN is a servo motor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. As an IndraDyn S synchronous servomotor, it delivers closed-loop torque and position control to automated axes in packaging machines, pick-and-place gantries, and other motion systems. The motor converts drive current into rotational movement, allowing precise speed regulation and coordinated interpolation in industrial automation cells. Its compact format makes it suitable for machine layouts that need accurate motion without adding unnecessary mechanical complexity.

For thermal management, the unit relies on natural convection, so cabinet airflow or external fans are unnecessary as long as ambient limits are respected. Frame size 075 indicates the stator diameter, while length code D gives the motor a longer active stack for higher continuous torque within the same mounting pattern. Winding code 0450 matches the electrical characteristics expected by compatible IndraDrive amplifiers. A shaft with a keyway transmits torque through positive mechanical engagement, and the increased concentricity design helps reduce runout at the coupling. The motor is supplied without a holding brake, so standstill holding must be provided by the drive or by an external clamp when the axis is stopped.

The feedback package uses the EnDat2.1 encoder interface for bidirectional communication that carries position data and stored motor data over a single twisted pair. An optical scanning system generates 2048 signal periods per revolution, and the encoder also provides a multiturn absolute position value so the axis can retain position information after power loss. To simplify wiring in tight cabinets, the encoder plug is rotatable, 240°, which allows the cable exit to be aligned after installation. This arrangement supports neat cable routing in compact machine spaces and helps reduce strain on the feedback connection during assembly and operation.
