Product Description:

The MSK075E-0300-FN-M1-UP1-NNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat in the MSK IndraDyn S Synchronous Motors series. It provides tightly regulated torque and position control for automated axes, packaging machinery, and material-handling stations where fast, precise response is required. As a synchronous servo motor, it works with a matching drive to convert controlled electrical input into rotary motion with stable speed and accurate positioning. A rotatable 240° encoder connector also simplifies cable routing in compact machine layouts.

This model uses liquid cooling, so circulating coolant removes heat directly from the stator and allows higher continuous load than comparable air-cooled units. Feedback is transferred through the Hiperface interface, enabling position data and electronic nameplate data to travel on one pair of wires. The optical encoder resolves motion into 128 signal periods, supporting fine interpolation by the drive during closed-loop control. An electrically released brake supplies 23 Nm of static holding torque to secure vertical or loaded axes during power loss. The housing is rated IP65, which helps keep out dust and water jets when the motor is mounted directly on the machine. Standard design construction, winding code 0300, motor size 075, and length code E set the electrical values used by compatible Rexroth drives for current limits and commutation.

Operation is specified within an ambient range of 0-40 °C, so additional cabinet cooling is not needed when the surrounding air stays inside this window. Thermal class 155 insulation permits winding temperatures up to 155 °C during operation and supports repeated high-load cycles. Power is delivered through a shaft with keyway, which provides positive torque transfer to couplings or pulleys without relying only on friction. Position information is retained after power is removed because the encoder is a multiturn absolute type that tracks revolutions mechanically. This encoder arrangement helps the control system restore axis position after restart without requiring a new reference move on every cycle.
