Product Description:

The MSK050B-0300-NN-M2-UP1-RNNN is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. As a compact rotary actuator, the motor converts drive current into precise torque and speed so that positioning tables, pick-and-place axes, and similar machinery can follow tightly controlled motion profiles inside automated production cells. Its closed-loop operation supports accurate starts, smooth speed changes, and repeatable stopping during cyclic machine movement in packaging, assembly, and general material-handling equipment.

This model is cooled by natural convection, allowing it to dissipate heat through its housing without external fans or liquid circuits. Its rotor and stator use increased concentricity, which helps reduce radial runout and supports consistent motion quality across the speed range. Cable routing is eased by a field-wiring connector that is rotatable 240°, so the connector can be turned to suit the available cable path. Feedback data leave the encoder through the EnDat2.1 digital interface, and the measuring system provides 2048 signal periods per mechanical revolution for fine position evaluation.

The optical sensor stack records multiple revolutions and stores the count in a multi-turn absolute format, so the axis can report position after a power cycle. A spring-applied, electrically released brake supplies 6 Nm of holding torque, which helps secure vertical or overhung loads when the inverter is disabled. Mechanical power is transmitted through a shaft with a keyway, allowing standard keyed couplings or pulleys to be mounted without extra machining. The stator uses winding code 0300, matching the motor to compatible IndraDrive amplifiers while keeping the housing within the B-length envelope for size-050 frames.
