Product Description:

The MSK075D-0300-NN-M1-UG0-NNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. In industrial automation, this motor couples to an electronic drive to supply precise rotary motion and fast position-control loops for equipment such as feeders, indexing tables, and conveyor axes. Its compact electromechanical layout supports use in enclosed machines where installation space is limited and consistent motion response is required during repeated acceleration and stopping cycles.

Heat generated by the stator windings is dissipated through natural convection, so no external fan or liquid circuit is required, which helps keep the installation simple in closed machine spaces. The 0300 winding code indicates the electrical constants matched to IndraDrive power modules, and motor length D corresponds to the active iron stack used for continuous torque capacity. Position feedback is provided by an optical encoder that offers 128 signal periods per revolution and communicates through the Hiperface interface, enabling accurate commutation and position evaluation. Electrical interfaces are protected by an IP65 housing, and reliable operation is maintained within an ambient range of 0–40 °C. A plain shaft simplifies coupling to gearboxes or belt pulleys, and the motor is supplied without a holding brake, so any required holding force must be provided by the drive or external mechanics.

For installation flexibility, the encoder connector can be rotated through 240°, allowing cable runs to clear adjacent components and tight panel boundaries. The feedback device uses a multi-turn absolute encoder, so it records up to 4096 mechanical turns without battery support and allows position information to remain available after power cycles. The motor is built in size 075 with a standard housing that uses insulation class 155, permitting winding temperatures up to 155 °C before thermal derating begins. This combination supports compact servo applications that need dependable feedback retention and straightforward cable routing.
