Product Description:

The MSK075C-0300-NN-M2-UG0-RNNN is a synchronous servo motor built by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It is designed for closed-loop industrial positioning and velocity control. The unit converts drive current into precise rotary motion for packaging lines, material-handling gantries, and automated tooling.

The motor relies on natural convection to remove heat, so cabinet layouts must permit free airflow around the housing. A sealed IP65 enclosure blocks dust and water jets, allowing installation adjacent to process equipment. The permissible ambient range of 0–40 °C matches typical factory climates, and outside this span current derating is required. Position feedback travels through the EnDat2.1 interface, and the optical sensor delivers 2048 signal periods per revolution, yielding fine incremental values once interpolated by the drive. Class 155 insulation permits winding temperatures up to 155 °C without loss of dielectric strength. A plain shaft couples the rotor to gearboxes or pulleys without keyways, and the thermal load is balanced by the stator’s 075 frame diameter.

For mechanical precision, the stator and rotor are machined with increased concentricity, minimizing radial runout when high-speed cycles are executed. The feedback plug is rotatable through 240°, so cable exits can be aligned to cabinet walls or drag chains. Coil geometry follows the 0300 winding code, and the active section corresponds to motor length C inside the 075 size envelope. The optical transducer stores position across power loss by means of a Multiturn Absolute track, eliminating homing routines at startup. Because the unit is supplied without a holding brake, external locking is required or the drive must remain energized when static torque is necessary.
