Product Description:
The MSK050B-0300-NN-M2-UP0-RNNN servomotor is produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. This compact motor is intended for closed-loop drive packages where fast torque buildup and accurate speed regulation are required on packaging lines, pick-and-place gantries, and general automation axes. It integrates permanent-magnet excitation with stator windings matched to the application current loop so that commanded motion follows controller signals with minimal lag. The result is responsive rotary output for indexing, positioning, and synchronized axis movement in compact machine layouts.
Thermal management depends on natural convection, meaning heat disperses through the housing surface without fans or liquid circuits. The mechanical design features increased concentricity, which helps minimize radial runout when the keyed shaft is coupled to gearboxes or pulleys. The motor uses size code 050 for a compact stator diameter that suits dense multi-axis arrangements. Winding code 0300 matches the motor to compatible drive modules for the required voltage constant and current range. The B-length housing provides an intermediate active stack that balances torque output and inertia, and the unit is supplied without a holding brake, so vertical loads require external holding force when power is removed.
A rotatable 240° connector allows the cable outlet to be positioned in the required direction inside crowded enclosures. The encoder communicates over EnDat2.1, providing bidirectional data exchange for parameter handling and feedback transmission. Its internal scale provides 2048 signal periods per revolution, and a multiturn absolute system preserves revolution data so the controller knows the shaft position after power cycles. The sensing principle is optical, which supports strong noise immunity and stable signal quality during contouring and interpolation tasks. This feedback arrangement helps the motor maintain precise motion control while keeping cable routing flexible in confined installations.
