Product Description:
The MSK075E-0450-FN-S2-UG0-RNNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat and positioned within the MSK IndraDyn S Synchronous Motors series. Designed for precision positioning and velocity control in industrial automation, this motor combines a 075 frame with an E-length stator to provide a compact, high-torque solution for multi-axis machinery where dynamic response and accuracy are required. Its synchronous design supports repeatable acceleration, stable speed regulation, and precise coordination with closed-loop servo drives. That makes it suitable for packaging systems, transfer axes, and other machines that rely on controlled rotary motion.
The winding code 0450 identifies the electrical layout used with the matching drive family, while increased concentricity in the mechanical design helps minimize runout during rotation. Process heat is removed by liquid cooling, allowing continuous operation inside a sealed IP65 housing. Service conditions are limited to an ambient range of 0 to 40 °C, and the motor is supplied without a holding brake, so external holding force is needed when power is removed. A rotatable encoder connector eases cable routing, and the optical feedback system uses the EnDat 2.1 interface with 2048 signal periods to provide fine position feedback to the drive controller. The encoder also stores electronic motor data, which allows the drive to access feedback-related information directly from the motor.
The motor uses a plain shaft, which avoids keyway-related imbalance and supports accurate coupling alignment. The encoder uses a single-turn counting method suited to axes that return to a reference position during the machine cycle. The connector can rotate through 240°, which helps when cable entry space is limited or when the motor must be mounted in tight equipment layouts. Thermal endurance is supported by insulation class 155, which helps protect the windings during sustained operation with coolant flowing through the housing.
