Product Description:

The MSK075C-0300-NN-M2-UG1-RNNN belongs to the MSK IndraDyn S Synchronous Motors series produced by Bosch Rexroth Indramat. It is a permanent-magnet servomotor intended for closed-loop position and velocity control on packaging lines, handling robots, and machining centers where quick acceleration and precise repeatability are required. Its synchronous design supports responsive motion on axes that need stable torque and accurate positioning during changing operating speeds.

The motor relies on natural convection to remove heat from the stator, so no auxiliary blower or liquid circuit is necessary. A housing sealed to IP65 prevents dust ingress and protects the windings from low-pressure water jets during washdown. Feedback data are transmitted through the EnDat2.1 serial interface, and the optical system supplies 2048 signal periods per revolution for fine angular resolution during interpolated drive control. Because the scanning module is a multiturn absolute design, the controller can read shaft position across several mechanical revolutions without a homing routine after power-up. The internal rotor and stator geometry use tight concentricity tolerances, which reduce cogging torque at low speed and support smoother interpolation on high-precision axes.

The shielded encoder connector is rotatable, 240°, allowing the cable outlet to be aligned inside tight machine frames while maintaining strain relief. An electrically released holding brake supplies 23 Nm of static torque to secure vertical loads when drive power is removed. Continuous operation is permitted within an ambient range of 0-40 °C, which matches most control cabinet climate ranges. Thermal class 155 insulation allows the copper to reach 155 °C before degradation, providing margin for intermittent overloads. The motor has a plain shaft for direct coupling and uses winding code 0300 with motor length C and size 075.
