Product Description:

The MSK075D-0300-NN-S1-UP1-NNNN is a synchronous servomotor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It is intended for closed-loop industrial automation where compact rotary axes must accelerate precisely and hold position under load. The motor interfaces directly with IndraDrive servo amplifiers, translating drive current into controlled torque for packaging machines, pick-and-place robots, and metal-cutting spindles. Its compact format also suits machine layouts where responsive motion and accurate positioning are required without adding unnecessary bulk.

Thermal management is handled by natural convection, so no external blower or liquid circuit is required, and enclosure fins dissipate heat generated by the stator. A winding code of 0300 identifies the electrical winding used with standard IndraDrive controllers. Position feedback comes from an optical encoder that delivers 128 signal periods per revolution and communicates through the Hiperface serial interface for absolute position reporting. Because the encoder is single-turn, it reports position within one mechanical revolution before rollover. An electrically released holding brake provides 23 Nm of static torque, helping keep the shaft locked during power-off conditions or emergency stops.

The motor size of 075 gives a stator diameter that balances torque density with installation space, while the length code D uses a longer active stack for higher continuous output. A shaft with keyway provides positive torque transmission to pulleys or gearboxes without relying only on friction at the coupling. Cabling flexibility is improved by an encoder connector that is rotatable 240°, allowing the cable outlet to be positioned around nearby components. This arrangement can simplify routing in crowded machine frames and helps reduce cable strain where adjacent axes or guards limit available space.
