Product Description:

The MSK070E-0450-NN-S2-UP0-RNNN is a synchronous servomotor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. The unit is identified as a synchronous servomotor in the IndraDyn S group and is used in automation where closed-loop speed and torque control must be delivered directly at the machine shaft. This arrangement lets the drive regulate motion precisely during repeated starts, stops, and speed changes in automated equipment where stable shaft response is important.

Heat is removed from the stator surfaces by natural convection, so no external blower or liquid circuit is required. A protection rating of IP65 seals the housing against dust ingress and low-pressure water jets, allowing cabinet-free mounting on production equipment. Position data come from an optical encoder with 2048 signal periods per revolution, and the digital feedback is transmitted through the EnDat2.1 interface for interpolation by the drive controller. The encoder connector can be swiveled through 240°, which helps with cable routing in confined assemblies. Mechanical accuracy is improved by the motor’s increased concentricity design, and the length E stator stack works with the size 070 lamination width to balance torque density and overall weight while keeping the motor compact for dense machine layouts.

This model is supplied without a holding brake, so static load retention must be handled by the drive or by external locking devices. Continuous operation is specified within an ambient range of 0 to 40 °C, and electrical insulation meets class 155 for the winding temperatures associated with cyclic servo duty. A keyed output shaft, described as a shaft with keyway, provides positive torque transmission to couplings or pulleys and helps prevent slip during rapid reversals. The winding code 0450 identifies the conductor gauge and turn count used in the stator slots, supporting the rated current and voltage pairing for this motor.
