Product Description:

The MSK075E-0300-NN-M3-UG1-NNNN is an IndraDyn S synchronous servo motor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. The unit is intended for closed-loop motion axes where accurate speed and position control are required, allowing a drive controller to move loads with repeatable precision in automated assembly cells, material-handling gantries, and packaging equipment. A compact mechanical frame combines the active stator, feedback electronics, and an electrically released brake to simplify installation.

The motor frame follows a 075 size code and is built in the E length variant, giving additional active iron for higher power density without changing the mounting interface. Its winding uses code 0300, so the electrical parameters match drive inverters in the correct current and voltage class. A plain shaft transmits torque directly to couplings or belts, and the motor uses a standard design with no optional liquid jacket or special coating. For static load retention, the internally mounted brake delivers 23 Nm of holding torque once the release coil is de-energized. The housing has an IP65 protection rating, which seals the internal laminations, windings, and bearing seats against dust ingress and low-pressure water jets encountered on factory floors.

Signal integrity is maintained by a rotatable 240° encoder connector that eases cable routing in tight panels, while the feedback itself uses the Hiperface interface. Position data come from a capacitive sensing system with 16 signal periods of resolution and a multi-turn absolute count, so mechanical homing routines are unnecessary after power cycles. Heat is removed solely through natural convection, allowing the motor to operate within an ambient range of 0–40 °C without forced airflow. Insulation class 155 permits winding temperatures up to 155 °C, offering thermal headroom for the duty cycles typical of indexing or continuous-process drives.
