Product Description:

The MSK075C-0300-NN-M1-UP2-NNNN is a synchronous servomotor from Bosch Rexroth Indramat in the MSK IndraDyn S Synchronous Motors series. It supplies closed-loop rotary motion for positioning tables, pick-and-place heads, and other CNC or PLC-driven axes used in general automation. The winding code 0300 indicates the stator turns and resistance used by the motor.

The motor body is classified as size 075 with a length code C, giving a power-to-weight ratio suited for medium-frame machinery. A shaft with a keyway simplifies torque transfer to standard couplings, and the housing carries a protection rating of IP65, so dust and low-pressure water jets do not reach internal components. An electrically released brake supplies 30 Nm of static holding torque to secure vertical or suspended loads when mains power is removed. Feedback is handled by an optical encoder that communicates through the Hiperface interface; its scale produces 128 signal periods per mechanical revolution, supporting fine velocity and position loops. The design is marked as Standard, so no special shaft seals or flange variants are added.

The motor uses natural convection cooling, and operation is approved within a 0–40 °C ambient window, so forced ventilation is unnecessary as long as surrounding air can circulate freely. The encoder is Multiturn Absolute, so it stores position across revolutions and eliminates the need for homing after power-up. Its connection plug can be rotated through 240°, aiding cable routing in confined cabinets. Insulated windings conform to class 155, allowing a winding temperature rise compatible with typical servodrive overload profiles. A general Requires Cooling FN note indicates that the drive monitor must enforce temperature limits during prolonged high-load duty.
