Product Description:

The MSK075E-0450-FN-M2-UG0-RNNN is a synchronous servomotor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It is intended to deliver precise rotary motion for axes that require high positioning accuracy and fast speed changes in automated machinery and production cells. When paired with a compatible Rexroth drive, the motor converts digital commands into controlled mechanical rotation for conveyor, pick-and-place, and tooling functions. Its design suits applications that need repeatable motion and stable closed-loop control during frequent starts, stops, and direction changes.

Thermal management is handled by liquid cooling, which circulates coolant through the stator jacket and helps keep winding temperatures within limits during continuous duty. The feedback assembly uses an EnDat2.1 serial interface, enabling position data and parameter transmission to the drive. Inside the encoder, an optical scanning head generates 2048 signal periods, and the system stores position as a multiturn absolute value so the controller can retain shaft position information after power cycling. A rotatable 240° encoder connector simplifies cable routing, and the motor is supplied without a holding brake, so position must be maintained by external clamping or drive-controlled torque when power is removed.

The housing is rated IP65, which helps protect the motor against dust ingress and water jets during machine operation. The approved ambient operating range is 0 to 40 °C, making the unit suitable for typical industrial environments, and the windings use class 155 insulation for dependable thermal endurance. Winding code 0450 identifies the electrical characteristics used with the matching drive settings. Size 075 with length code E gives the motor a compact form for medium-torque axes, and the plain shaft supports precise couplings without key-related backlash.
