Product Description:
The MSK076C-0450-NN-M1-UP1-NSNN is an IndraDyn S synchronous servomotor from Bosch Rexroth Indramat and belongs to the MSK IndraDyn S Synchronous Motors series. As an electromechanical actuator, the motor supplies controlled torque and speed to automated axes, enabling coordinated movement in packaging, printing, and material-handling cells. Integrated feedback and a spring-applied, electrically released holding brake allow the unit to maintain position during power loss while providing precise rotor data to the drive controller for closed-loop operation. This combination supports accurate starts, stops, and holding functions on servo-driven machine axes.
Thermal management relies on natural convection, so installation must allow free airflow around the housing. The enclosure carries a protection rating of IP65, which prevents dust ingress and resists low-pressure water jets on open machine frames. Continuous service is specified between 0–40 °C, matching standard shop-floor climates and supporting the motor’s Class 155 insulation system. A spring-applied brake supplies 11 Nm of static holding torque and is released electrically to prevent shaft drift when power is removed. Position sampling is performed by an optical encoder that delivers 128 signal periods per revolution, giving the drive stable feedback for closed-loop control. The C length, 076 frame size, and 0450 winding code determine the motor’s electrical behavior and inertia profile. The unit also has a standard and explosion-protection design for use in designated hazardous areas.
The feedback hardware communicates through the Hiperface interface, allowing one cable path to carry power and digital position data. Service access is aided by a rotatable connector that can turn through 240°, which helps with cable routing in compact cabinets and machine frames. Absolute rotor position is retained across 4096 turns through the encoder’s multiturn absolute capability, so the axis can recover position data after power is restored. Mechanical coupling to the load is provided by a shaft with keyway, a common profile that helps prevent slip under reversing torque. This shaft style also matches many standard hubs and couplings used in servo-driven machinery.
