Product Description:

The MSK075E-0300-NN-S1-UG1-NNNN is a synchronous servo motor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It is used in automated assembly lines, packaging machines, and gantry systems where precise torque delivery and fast position control are required to keep mechanical movement aligned with controller commands. When paired with a compatible drive, the motor supports accurate axis motion during indexing, positioning, and repeatable cycle changes. Its compact construction also suits machine layouts where responsive motion and consistent feedback are required in the same unit.

This model uses natural convection for cooling, so heat is removed without forced-air ducting. The motor includes a holding brake with 23 Nm of static torque, and the brake is electrically released when power is applied to the brake coil. The housing is sealed to IP65, which helps keep out dust and low-pressure water jets during normal operation. A plain shaft transfers torque without keyways, which helps reduce backlash in precision couplings. Motor feedback is carried through a Hiperface interface that transmits position data and electronic nameplate information over a single cable. The encoder uses an optical scanning method with 128 signal periods, and the connector can be rotated by 240° to suit tight cable routing.

The feedback system uses a single-turn code track, so it provides absolute position within one mechanical revolution without multi-turn gearing. Continuous operation is permitted at ambient temperatures from 0 to 40 °C, which fits typical plant-floor conditions. The winding insulation is class 155, allowing the motor to tolerate winding temperatures up to 155 °C before insulation damage occurs. Winding code 0300 identifies the electrical setup used in this 075-frame motor, while the 075 mm stack diameter balances torque density with inertia for fast indexing tasks. The E-length frame also provides the surface area needed to dissipate normal operating losses during continuous use.
