Product Overview

The MSK076C-0450-NN-M1-UG1-NNNN is a medium-frame high-torque synchronous servo motor from Rexroth’s classic MSK IndraDyn S platform, designed for closed-loop high-precision motion control in automated machinery. It adopts high-energy-density rare-earth magnet rotor design, delivering outstanding acceleration performance and low torque ripple under continuous cyclic operation.

It solves core motion control pain points: insufficient torque output for heavy-duty linear/rotary axes, complex cooling layout for enclosed equipment, low-resolution encoders causing positioning deviation, and bulky motor structures limiting mechanical cabinet space. CNC machine tool designers, packaging machine OEMs, automated assembly line engineers and printing equipment technicians achieve rigid, repeatable axis positioning with this Rexroth servo motor.
