Product Description:

The MSK075E-0450-NN-S1-UG2-NNNN is a synchronous servomotor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It is used for precise torque and position control on industrial automation axes such as packaging machines, pick-and-place gantries, and material-handling lines. When paired with a compatible drive, the motor supports closed-loop motion with stable speed regulation and accurate positioning. This motor type is intended for servo systems that require quick response to command changes and reliable repeatability during cyclical operation. Its compact design also suits applications with frequent starts, stops, and direction changes.

The unit uses natural convection for heat dissipation, so space around the housing is needed for airflow. This cooling method avoids external fans and keeps the housing layout simple. The aluminum housing has an IP65 rating that protects internal parts from dust and low-pressure water jets. Drive torque is transferred through a plain shaft, which supports direct coupling in aligned mechanical systems. An electrically released holding brake provides 30 Nm of static torque to hold loads when power is removed. Insulation class 155 supports continuous operation at ambient temperatures from 0 to 40 °C. The motor uses frame size 075 in length E and follows the standard design for this platform.

For feedback and cabling, the encoder connector can be rotated through 240°, which helps route cables in confined machine spaces. Communication with the drive uses the Hiperface protocol, which carries position data and electronic nameplate information over the same interface. The feedback module uses an optical measuring system with 128 signal periods, and its single-turn construction provides absolute position information within one mechanical revolution. Absolute feedback at startup reduces the need for a reference move after power is restored. Winding code 0450 matches the motor's electrical behavior to compatible IndraDrive amplifiers, which helps the drive respond consistently under changing load conditions.
