Product Description:
The MSK075E-0450-NN-S2-UP0-RNNN servomotor is produced by Bosch Rexroth Indramat and belongs to the MSK IndraDyn S Synchronous Motors series. As an IndraDyn S synchronous servomotor, it supplies precise torque and position regulation for automated axes in packaging, printing, and material-handling lines. The model uses permanent-magnet technology and integrates seamlessly with Rexroth drive controllers to form closed-loop motion modules for industrial automation. Its compact frame helps machine builders reduce cabinet depth while maintaining dynamic response.
This unit relies on natural convection for heat removal, so airflow around the housing is critical when the ambient sits within the specified 0–40 °C operating range. The rotor and stator are machined for increased concentricity; this minimizes radial runout and improves encoder accuracy. Position feedback is delivered through an EnDat2.1 optical system that generates 2048 signal periods per revolution, and the connector can be rotated 240° to simplify cable routing in tight cabinets. An IP code of IP65 keeps internal components sealed against dust and water jets, while the single-turn protocol reports absolute position within one mechanical revolution. The motor ships without a holding brake, and its frame size with length E corresponds to the electromagnetic package used for this winding.
Mechanical energy is transferred through a shaft with keyway, allowing keyed couplings to seat securely without relying on friction fits. Thermal endurance is governed by insulation class 155, so continuous winding temperature may rise to 155 °C before degradation. The dedicated winding set marked 0450 sets the phase resistance and inductance values for this magnetic geometry, giving predictable current demand when the motor is paired with compatible IndraDrive amplifiers.
