Product Description:

The MSK071D-0450-NN-S2-UP0-RNNN synchronous servomotor is manufactured by Bosch Rexroth Indramat and is part of the MSK IndraDyn S Synchronous Motors series. In an automation cell, it acts as the direct mechanical driver for feed axes, robotic joints, or indexing tables, converting drive amplifier current into controllable torque and speed. Frame code 071 identifies the motor size, while the D length provides a larger active section for higher continuous torque. The 0450 winding code matches the commutation data used by compatible drives.

Its housing is cooled by natural convection, so heat is dissipated through the surface without forced airflow, which is useful when space for fan-assisted cooling is limited. The integrated feedback system uses the EnDat2.1 serial interface and an optical measuring principle that provides 2048 signal periods per revolution, giving the controller accurate rotor position data. A field-installable encoder plug that is rotatable through 240° simplifies cable routing in tight machines and helps align the connection with available cable paths. The motor body has an IP65 rating, which prevents dust ingress and protects against water jets during operation. The mechanical design uses increased concentricity to reduce runout and support smooth motion at higher speeds.

The unit is supplied without a holding brake, so static load holding must be provided externally when the application requires it. A shaft with a keyway transfers torque to couplings without slippage, and the encoder is a single-turn type rather than a multi-turn design. Continuous service is supported from 0 to 40 °C in ambient air. Class 155 insulation resists internal winding temperatures up to 155 °C. These operating limits suit standard industrial use where the motor is installed with appropriate thermal clearance.
