Product Description:

The MSK075C-0300-NN-S1-UG0-NNNN is an IndraDyn S synchronous servomotor built by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It converts drive commands into accurately regulated rotary motion for positioning, feeding, and indexing axes in automated equipment. Size 075, length code C, and winding code 0300 identify the motor configuration, while the plain output shaft supports direct coupling to the driven load. The motor uses a standard mechanical design, so it can be mounted on common machine structures without special adapters and cooled by ambient air around the housing.

Heat generated in operation is removed by natural convection, eliminating fans or liquid circuits. The housing carries an IP65 protection rating, so dust and low-pressure water jets are kept away from internal components. Position feedback is provided through a Hiperface encoder with 128 signal periods per revolution, which the drive can interpolate for precise motion control. The encoder connection is rotatable through 240°, making cable routing easier when space around the motor is limited. The motor is supplied without a holding brake, so any static holding function must come from the drive or from external mechanical equipment.

The permitted ambient temperature range is 0–40 °C, which allows continuous operation without derating when the surrounding air remains within that band. Inside that range, the encoder uses an optical sensing principle in a single-turn format, so absolute position is available within one mechanical revolution after power-up. The motor uses insulation class 155, which corresponds to Class F winding materials and supports elevated winding temperatures during cyclic motion. Typical applications include packaging machines, handling systems, and other servo axes that require accurate speed and position control.
