Product Description:

The MSK075E-0450-NN-M1-UP0-NNNN is a synchronous servomotor produced by Bosch Rexroth Indramat in the MSK IndraDyn S Synchronous Motors series. It provides closed-loop rotary actuation for CNC equipment, packaging machines, and other automated axes that demand precise torque and position control. The motor is suited to applications that require repeatable starts, stops, and speed changes, and its output shaft can be coupled directly to pulleys or other transmission components for accurate motion transfer. This makes it appropriate for indexing axes, feed drives, and synchronized handling movements where the controller must keep commanded and actual position closely aligned throughout the cycle.

Heat is removed through natural convection, so the mounting location must permit unobstructed airflow rather than depend on external blowers or liquid circuits. The housing carries an IP65 rating, blocking dust ingress and resisting low-pressure water jets, which supports installation on machines exposed to lubricants or routine washdown. Position feedback travels over the Hiperface interface, giving the drive a digital channel for real-time data exchange. Within the encoder, a grating delivers 128 signal periods, which helps the controller maintain smooth low-speed motion and respond quickly to changing load conditions. Because cooling is passive, the motor can be used where simpler machine layouts are preferred and where additional fan maintenance is undesirable.

Signal capture uses optical scanning, which supports stable phase accuracy despite vibration or minor temperature drift. The feedback device is a multi-turn absolute type, so mechanical position is retained after power loss and no homing cycle is required at startup. The encoder arrangement gives the connected drive immediate position availability after restart, which can shorten machine recovery time after planned shutdowns or brief interruptions. Rated operation covers ambient temperatures from 0–40 °C, which suits standard factory environments when reasonable ventilation is available. Mechanical power is transmitted through a shaft with a keyway, and insulation class 155 permits winding temperatures up to 155 °C during short overload events.
