Product Description:

The MSK070C-0300-NN-S2-UP0-RSNN servo motor is built by Bosch Rexroth Indramat and belongs to the MSK IndraDyn S Synchronous Motors series. Designed for closed-loop positioning and speed control, the unit provides the rotary actuation required in pick-and-place robots, tool changers, and converting lines. Internal construction with increased concentricity limits radial runout, and integrated explosion protection allows installation in classified production zones. This arrangement supports smooth motion on axes that start and stop frequently, especially where stable rotation is required during precise machine cycles.

Thermal management is handled through natural convection, so the housing dissipates heat to ambient air without auxiliary fans or liquid circuits. Feedback is delivered over the EnDat2.1 interface, and the encoder connector can be rotated through 240° to simplify cable routing in tight cabinets. The integrated measuring system produces 2048 signal periods per mechanical revolution, and its optical scanning principle maintains high accuracy by avoiding magnetic hysteresis. Because the code disk tracks only one mechanical revolution, the device is classified as single-turn, which suits applications that reestablish position at power-up while still demanding fine interpolation during motion. The feedback channel also allows the drive to monitor rotor position directly during both speed changes and positioning moves.

Mechanical drive coupling is simplified by a shaft with keyway, giving positive torque transmission to standard hub elements. The motor ships without a holding brake, so power-off retention must be provided by the drive's static current or by external clamps. The winding code is 0300, and the stator stack uses motor length C, giving a mid-length housing that balances continuous torque with overall package depth. That combination is suitable for multiaxis equipment that needs moderate installation depth while maintaining secure torque transfer at the shaft.
