Product Description:
The MSK075E-0450-NN-S1-UG1-NNNN synchronous servomotor is built by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It is intended for precision positioning and continuous-duty motion in industrial automation, driving axes that require repeatable speed profiles and accurate end-point positioning. Integrated feedback, a holding brake, and sealed construction allow the motor to mount directly on machinery without auxiliary enclosures. This arrangement supports compact axis layouts where stable closed-loop control and reliable stopping behavior are needed during long production runs.
Heat is removed by natural convection, so the housing needs free air around it and no external fan is required. An electrically released holding brake supplies 23 Nm of static torque, allowing vertical or suspended loads to remain locked when the drive is disabled. The enclosure carries an IP65 rating, blocking dust ingress and water jets so the motor can operate near cutting fluids or washdown areas. Position data travel through the digital Hiperface interface, and the feedback element uses optical scanning to provide clear signals during extended duty cycles. A rotatable encoder connector with 240° of swing also helps route cables through tight machine spaces.
The optical sensor provides 128 signal periods, and because it is configured as a single-turn device, it delivers an absolute position within one mechanical revolution without external batteries. A plain shaft is supplied for backlash-free couplings, and the rotor uses the medium frame diameter of 075 with length code E and winding code 0450 for balanced torque density. The insulation system is rated to class 155, allowing extended duty at ambient temperatures of 0–40 °C. All power, brake, and feedback lines exit through one connector, which keeps cable routing orderly when the motor is installed in confined machine layouts.
