Product Description:

The MSK075D-0450-NN-M2-UG0-RNNN synchronous motor is produced by Bosch Rexroth Indramat and belongs to the MSK IndraDyn S Synchronous Motors series. It functions as a torque and position actuator in CNC machinery, packaging lines, and automated handling stations where rapid acceleration and closed-loop feedback are required. The motor couples directly to gear stages or load shafts, converting drive output from an IndraDrive controller into rotational motion for precise axis control within an automation cell. Its operating role suits applications that need responsive speed changes and repeatable positioning during continuous machine cycles.

Cooling is provided by natural convection, so heat leaves the housing without external blowers. Adequate surrounding airflow is required to keep winding temperatures within limits. The motor has a frame size of 075, which sets the flange diameter, and a motor length of D, which adds active copper for higher continuous torque. Winding code 0450 sets the resistance and inductance used with compatible medium-voltage, medium-current drives. A plain shaft allows connection through a shrink disk, keyless hub, or collet, and the internal geometry uses increased concentricity to reduce runout and support bearing life.

Position feedback uses the EnDat2.1 serial interface, which carries position and diagnostic data over a shielded pair to simplify cabling. The optical scanner provides 2048 signal periods, and the multiturn absolute feature retains shaft position across multiple revolutions when power is off, which reduces the need for homing after restart. The encoder connector can rotate 240° to help with cable routing, and the optical system offers strong noise immunity in high-response servo loops. The motor is supplied without a holding brake, so any static load that must remain fixed during power loss requires external holding.
