Product Description:

The MSK070E-0300-NN-S2-UP1-RNNN is a synchronous servomotor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It is used in industrial automation to drive axes that require accurate positioning and repeatable speed control. Its compact dimensions and improved concentricity help reduce vibration when the motor is coupled to precision gearboxes, ball screws, or direct-drive assemblies. This makes the unit suitable for motion systems where stable rotation and smooth response are important during continuous production.

This model uses natural convection for cooling, allowing installation in cabinets where forced airflow is not available. Position feedback is provided through an EnDat 2.1 optical encoder with 2048 signal periods per revolution, enabling fine interpolation inside the drive controller. For power-loss protection, the electrically released holding brake provides 23 Nm of static torque to secure vertical or suspended loads. The housing has an IP65 rating, which helps block dust and water jets commonly found on production floors. Continuous operation is supported at ambient temperatures from 0 to 40 °C, so the motor can be installed in standard equipment enclosures without additional climate control.

The motor uses insulation system class 155, which supports winding temperatures that align with common drive protection thresholds while preserving service life. Mechanical coupling is handled by a shaft with keyway, providing positive torque transmission to pulleys or couplings while maintaining alignment. Its 0300 winding code corresponds to electrical values matched to IndraDrive power sections, helping the current loop respond predictably during acceleration and load changes. This combination of encoder feedback, brake function, and practical shaft geometry fits machinery that needs controlled motion with secure holding at standstill.
