Product Description:

The MSK075E-0300-NN-M1-UG2-NNNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat and part of the MSK IndraDyn S Synchronous Motors series. The 075 frame size provides a mid-range mechanical envelope, and the E length balances rotor inertia with thermal capacity. A 0300 winding set is installed to match drive voltage and current ratings. Within industrial automation, the unit converts commanded stator currents into rotation so that linear slides, indexing tables, or rotary actuators achieve accurate positioning and repeatable cycle times.

Environmental and electrical limits shape how the motor is integrated. The housing carries an IP65 protection rating, sealing the stator and encoder against dust and low-pressure water jets. Continuous operation is allowed between 0–40 °C. An internally mounted, electrically released brake supplies 30 Nm of static holding torque for vertical or safety-critical axes. Feedback is transmitted through the Hiperface serial interface, and its optical scale provides 128 signal periods per mechanical revolution, allowing high-resolution interpolation inside the drive controller. A rotatable 240° connector eases cable routing, and the standard design classification indicates that no special coatings or mechanical deviations are present.

Thermal behavior follows the FN cooling requirement; this variant relies on natural convection, so heat dissipates across the ribbed housing without fans or liquid jackets. The integrated encoder uses multi-turn absolute counting to track shaft position over multiple revolutions even after power loss, and its optical sensing principle minimizes quantization error at high speeds. A plain shaft interface simplifies coupling to gearboxes or direct-drive loads while reducing radial seal wear. The motor carries class 155 insulation to withstand elevated copper temperatures during overloads, and the rotatable connector helps maintain strain relief as conductors exit the machine frame.
