Product Description:

The MSK075E-0450-NN-S1-UP1-NNNN is a synchronous servomotor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It provides precise torque and position control for automated axes in packaging, printing, and material-handling equipment. The combination of the 075 frame size and E-length stator gives the motor a compact footprint while supporting demanding servo motion. Winding code 0450 pairs it with compatible IndraDrive controllers for coordinated multi-axis operation. This motor is intended for closed-loop applications where consistent response during changing speed and load conditions is important to machine timing.

Thermal management relies on natural convection, so installation must allow unobstructed airflow around the housing and should avoid trapping heat near the motor body. The motor carries an IP65 enclosure rating, which keeps out dust and resists low-pressure water exposure in industrial areas. Motion is held during power-off by an electrically released brake with 23 Nm of torque, which helps prevent axis drift when the load must remain in place. Power is transmitted through a shaft with a keyway, allowing secure coupling to pulleys, couplings, or gear units. Digital feedback is exchanged through the Hiperface interface, so the connected drive receives position data through a compact electronic link.

The encoder delivers 128 signal periods per revolution and uses optical scanning to support accurate interpolation in the drive. Its design is single-turn, so the feedback system reports absolute shaft position within one mechanical revolution. The motor also uses a standard mechanical design, and the rotatable connector with a 240° sweep helps route the cable in tight machine spaces without forcing an awkward exit angle. Approved ambient conditions range from 0–40 °C, and insulation class 155 allows the windings to tolerate normal internal heating during continuous duty. This layout is useful where the motor is mounted close to guarding, machine frames, or adjacent axes that leave limited room for cable routing.
