Product Description:

The MSK050B-0300-NN-S2-UG0-RNNN servo motor is manufactured by Bosch Rexroth Indramat and belongs to the MSK IndraDyn S Synchronous Motors series. It converts current from an IndraDrive controller into controlled mechanical torque for indexing tables, packaging axes, and other position-controlled duties in automated equipment. Its integrated feedback device lets the control loop correct position and speed in real time, which helps maintain repeatable motion during short cycles and frequent starts and stops. This makes the motor suitable for applications that need accurate acceleration, stable tracking, and compact installation space.

Thermal management uses natural convection, so heat is removed through the housing surface without external fans. The motor has size code 050, which places it in a compact frame for direct mounting or connection to medium-size transmission components. Winding code 0300 corresponds to the electrical characteristics expected by the matching drive, including the related current and voltage behavior. Position feedback is supplied by an encoder with 2048 signal periods per revolution over the EnDat2.1 serial interface, allowing smooth commutation, stable speed regulation, and accurate response to changing load conditions.

The feedback head uses a rotatable 240° connector, which makes cable routing easier when space around the motor is limited. The encoder uses optical sensing and operates as a single-turn system, so one shaft revolution is measured directly and the connected drive can process that position data without ambiguity inside the turn. The rotor is machined for increased concentricity, which helps reduce radial runout and supports direct coupling to precision mechanical components. The motor is supplied in the B length variant with a plain shaft and without a holding brake, making it a compact choice for axes that rely on drive-controlled stopping rather than brake engagement.
