Product Description:

The MSK075E-0450-NN-M1-UP2-NNNN is a servo motor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. As an IndraDyn S synchronous servomotor, it provides precise torque and position control for automation axes such as packaging heads, gantry drives, and robotic joints. The motor size 075 and E length give a compact form that fits machines requiring high dynamic response from closed-loop CNC or PLC motion systems. It works with a compatible drive to convert commanded current into controlled rotary motion during repeated starts, stops, and direction changes.

This model uses natural convection for cooling, so ambient airflow removes heat without external fans or liquid circuits. Its enclosure has an IP65 rating, which helps keep dust and water jets away from internal components when the motor is installed outside a control cabinet. An electrically released holding brake provides 30 Nm of static torque to hold vertical loads when power is removed. Feedback comes from a multi-turn absolute optical encoder with a Hiperface interface and 128 signal periods, which supports smooth low-speed regulation and retained position data through power cycles. The encoder connector can rotate 240° to simplify cable routing in tight mounting spaces.

Continuous operation is permitted at ambient temperatures from 0–40 °C. Power is transmitted through a shaft with keyway, which gives positive engagement with couplings or pulleys in motion systems that need secure torque transfer. The stator winding code 0450 matches the motor's electrical setup for the E-length version and allows the connected drive to supply the intended torque-speed behavior. The insulation class is 155, allowing winding temperatures up to 155 °C before insulation damage becomes likely. The motor uses a standard construction, so it does not include special housing or shaft modifications.
