Product Description:

The MSK050B-0450-NN-S1-UG0-NNNN is a synchronous servo motor produced by Bosch Rexroth Indramat and supplied within the MSK IndraDyn S Synchronous Motors series. This compact rotary unit couples with an IndraDrive controller to deliver closed-loop torque, speed, and position control on automated machinery. By converting electrical energy into precise mechanical motion, it streamlines conveyor diverters, pick-and-place heads, and form-fill-seal axes. The housing supports direct mounting to gearboxes or timing-belt pulleys, allowing drivetrain parts to be minimized while maintaining the dynamic response and repeatability required for high-cycle industrial production.

Thermal management relies on natural convection, so the ribbed housing dissipates losses without external fans or liquid circuits, simplifying cabinet ventilation. A Hiperface interface links the optical feedback device to the drive; this digital protocol transports absolute position and electronic nameplate data through a rotatable 240° encoder connector that allows strain-free cable exits in multiple orientations. Inside the encoder, 128 signal periods per mechanical turn establish fine resolution for smooth velocity and tight positioning loops. The motor body resists dust ingress and low-pressure water jets with an IP65 protection rating, enabling installation on open machine frames adjacent to product flow zones.

Rated operation is sustained in ambient temperatures from 0 to 40 °C without derating, so the motor covers typical factory environments. A plain shaft facilitates backlash-free clamp coupling or press-fit pinions, and an insulation class of 155 supports elevated winding temperatures during high-duty cycles. Electromagnetic characteristics follow winding code 0450, which matches the drive’s current limits for this size 050 motor with B length. The unit is supplied without a holding brake, reducing axial mass, while the single-turn optical encoder retains an absolute reference after each power-up.
