Product Description:

Bosch Rexroth Indramat manufactures the MSK075E-0300-FN-S2-BG3-RNBN within its MSK IndraDyn S Synchronous Motors series. The unit is a synchronous servomotor designed to convert electrical power from a drive into accurate mechanical rotation for production lines, pick-and-place gantries, and coordinated multi-axis systems in industrial automation. Its compact footprint and enclosed housing allow installation close to tooling while preserving the fast response needed for repetitive motion. This layout also supports use in machines where available mounting space is limited and direct motor coupling is preferred.

This model employs liquid cooling to remove heat directly from the stator, so continuous torque can be delivered without thermal derating. For position feedback, it integrates an optical encoder that communicates over EnDat2.1 and produces 2048 signal periods per revolution, which supports precise position control when used with drive interpolation. Because the encoder is single-turn, one electrical revolution represents one mechanical angle position, which suits short-stroke machines and other applications that do not require multi-turn position storage. Thermal stability in the winding system uses Class 155 insulation, allowing elevated conductor temperature within the permitted operating range.

The housing meets the IP65 protection rating, so the motor is protected against dust ingress and low-pressure water exposure when the plain cable glands are installed correctly. A plain shaft without a keyway helps reduce runout and is suited for clamp-type couplings. The motor can operate continuously in ambient temperatures from 0 to 40 °C without external heaters, and its electrical characteristics correspond to winding code 0300, which indicates the inductance and resistance values used by the matching drive. An electrically released holding brake is included, and the brake, encoder, and stator power are routed through a B-side connector. Physical proportions match motor size 075 and length E for consistent frame layout in machine assemblies.
