Product Description:
The MSK075E-0450-NN-S1-UG0-NNNN is a synchronous servo motor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. Within a closed-loop drive system, this motor converts electrical power from an IndraDrive controller into precise mechanical rotation, allowing conveyor heads, pick-and-place robots, and packaging seal bars to follow exact motion profiles. Its compact design supports direct coupling to gearboxes or load shafts, making it suitable for multi-axis automation while maintaining consistent feedback through an integrated optical encoder.
The frame code 075 gives the motor a stator outside diameter suited for medium power ranges and allows mounting with standard MSK flanges. The length code E indicates an extended axial stack that increases iron volume for higher continuous torque without substantially enlarging the overall footprint. Winding code 0450 sets the electrical characteristics so resistance, inductance, and voltage constant match compatible IndraDrive inverter stages. Heat from the windings is removed by natural convection, so the motor relies on ambient airflow rather than forced cooling hardware. The aluminum housing has an IP65 enclosure rating that blocks dust ingress and resists low-pressure water jets during washdown.
Position feedback is provided by a single-turn optical encoder that communicates through the Hiperface serial protocol, allowing the drive to read the absolute rotor angle immediately after power-up. The encoder provides 128 signal periods per mechanical revolution, so the controller can interpolate fine position increments for smooth velocity control. Installation flexibility is improved because the feedback connector can rotate 240°, which helps with cable routing in tight spaces. The servo motor operates in ambient temperatures from 0 to 40 °C, and it has a plain output shaft, Class 155 winding insulation, a standard mechanical design, and no holding brake, so load holding must be handled by an external clamp or drive-based torque.
