Product Description:

The MSK050C-0300-NN-S2-UP1-RNNN is a synchronous servo motor produced by Bosch Rexroth Indramat and included in the MSK IndraDyn S Synchronous Motors series. It converts drive-controller commands into precise rotary motion for positioning, contouring, and speed-regulated duties on packaging lines, pick-and-place gantries, and other automated machinery. The motor works as an electromechanical actuator that couples directly to the load, allowing the motion controller to supervise shaft position through integrated feedback. This arrangement supports accurate axis movement in applications that require repeatable starts, stops, and directional changes throughout normal production cycles.

Thermal management relies on natural convection, so heat is removed by ambient airflow without auxiliary fans or coolant. Feedback cabling attaches to a 240° rotatable connector, which eases routing when cable space is limited, and digital position data are transmitted through EnDat2.1. The encoder provides 2048 signal periods per revolution. Its optical scanning method supports consistent repeatability, and the single-turn format reports an absolute angle within one mechanical rotation. These features support responsive control behavior during rapid indexing, coordinated path motion, and other servo tasks that depend on stable feedback.

An electrically released holding brake provides 6 Nm of static torque to secure vertical or suspended loads when power is removed. The housing is rated IP65, which helps keep out dust and protects against low-pressure water jets, and continuous operation is permitted from 0 to 40 °C. The size 050 motor with length C fits compact installations, while the shaft uses a keyway for straightforward coupling to driven components. Increased concentricity in the rotor helps reduce radial runout, and the 0300 winding is paired with insulation class 155 for normal servo drive operation.
