Product Description:

The MSK050C-0450-NN-S2-UG0-RNNN is a synchronous servo motor built by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. As an IndraDyn S motor, it delivers controlled torque and speed to conveyors, pick-and-place axes, and other automated equipment that require precise rotary positioning. The unit integrates closed-loop feedback electronics with a compact stator so it can pair directly with IndraDrive controllers in machine-tool, printing, and packaging lines. It is suited to servo applications that need accurate speed regulation during repeated starts, stops, and position changes.

Its cooling method is natural convection, so the frame dissipates heat into the surrounding air without fans. The housing is machined for increased concentricity, which helps keep radial runout low under dynamic load. Feedback exits through a rotatable 240° connector, which can be turned to relieve cable strain in tight spaces. An optical sensor that uses the EnDat 2.1 protocol produces 2048 signal periods per revolution, supplying high-density position data to the drive. The motor uses a single-turn encoder, so absolute position is retained within one revolution and external homing cycles are unnecessary. It uses motor size 050, length C, and winding code 0450 for mid-inertia axes.

An IP65 rating seals the enclosure against dust and low-pressure water jets, allowing direct mounting on the machine frame. The rotor couples to loads through a plain shaft, which supports backlash-free clamping hubs or couplings. Because the motor is supplied without a holding brake, static loads must be secured by the drive or by external locks when power is off. Continuous service is permitted within a surrounding temperature of 0–40 °C, and the Class 155 insulation system supports reliable electrical isolation during thermal cycling.
