Product Description:

The MSK075E-0200-NN-M1-UG1-NNNN is a servo actuator produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. As an IndraDyn S synchronous servomotor, it converts controlled electrical energy from a Rexroth drive into rotational motion used to position tooling, conveyor segments, or gantry axes with high repeatability. The plain shaft configuration and standard mechanical design make the unit suitable for direct coupling to gearboxes or timing pulleys in industrial automation lines that demand consistent torque delivery and smooth low-speed operation.

Thermal management relies on natural convection, so heat dissipates through the housing without external fans; this influences cabinet layout because vertical airflow paths must stay clear. Feedback is carried through a rotatable 240° encoder connector that uses the Hiperface interface, allowing simultaneous position data and parameter storage between the motor and drive. The integrated encoder resolves 128 signal periods per mechanical revolution, providing fine granularity for interpolation in high-precision loops. A spring-applied, electrically released brake supplies 23 Nm of holding torque to secure vertical loads whenever power is removed. Internally, winding code 0200 tailors impedance to compatible drives, and the E length in the 075 frame increases active material for higher continuous output.

The motor body carries a protection rating of IP65, preventing dust ingress and resisting low-pressure water jets, so it can be mounted on exposed machine frames. Continuous operation is specified for ambient ranges of 0–40 °C; beyond this window, derating or forced cooling is required. The encoder’s Optical scanning principle in its Multiturn Absolute format delivers absolute position data over 4096 mechanical turns, eliminating homing routines after power cycles. Insulation system class 155 permits winding temperatures up to 155 °C, extending thermal life under cyclic loading.
