Product Description:

The MSK050B-0300-NN-S2-UP0-RNNN is a synchronous servo motor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It is intended for closed-loop positioning and speed control in packaging lines, handling robots, and general automation cells. The synchronous design supports precise torque production and stable speed regulation when used with a compatible drive controller. The motor has a 050 frame size, a B length code, and a 0300 winding code, which suit mid-range power requirements while fitting in tight mounting spaces.

Heat generated during operation is removed through natural convection, so the motor can be mounted without ducts, blowers, or coolant lines. Rotor and stator machining with increased concentricity tolerance minimizes radial runout, which supports accurate feedback alignment. The feedback connector is rotatable through 240°, which helps route the cable toward the cabinet or drag chain without twisting the harness. Position information is communicated over the EnDat2.1 digital interface, which carries absolute and incremental data on a bidirectional line. Inside the encoder, interpolation is performed across 2048 signal periods, giving fine angular resolution for smooth low-speed rotation and precise stop points.

The sensing system relies on an optical scanning method that is not affected by external magnetic fields and supplies stable reference edges. It is configured as a single-turn device, so absolute position is available within one mechanical revolution, while multi-turn counting can be handled by the controller if required. Torque is transmitted through a shaft with keyway, providing positive drive to gears or pulleys without relying only on frictional clamping. The motor is supplied without a holding brake, so static load retention must be achieved through drive current or an external locking element. This omission reduces mass and rotor inertia for faster acceleration in high-cycle machines.
