Product Description:
The MSK131B-0200-NN-S2-APO-RNNN is an IndraDyn S synchronous servo motor engineered by Bosch Rexroth Indramat and assigned to the MSK IndraDyn S Synchronous Motors series. In modular production cells, it converts electrical power into accurate shaft motion for indexing tables, linear actuators, and tool spindles. Internal position feedback eliminates the need for mechanical potentiometers, enabling high stiffness and repeatability where fast position settling and velocity stability are critical. The motor is frequently used for conveyors, transfer stations, and servo-driven presses that require precise operating cycles.
Heat generated in the stator is dissipated through natural convection, so the motor does not require an auxiliary blower. The shaft has a keyway that provides direct torque transmission to pulleys or gearboxes, while the machined, increased-concentricity design reduces radial runout for smoother rotation. Field wiring attaches to the power connector on side A, which supports organized cable routing around the motor housing. Precise rotor angle data is transmitted over a bidirectional synchronous serial interface that complies with EnDat 2.1. The sensing head uses optical encoder technology and provides 2048 signal periods per mechanical revolution. This resolution allows the controller to interpolate additional counts for fine position measurement and accurate closed-loop motion control.
Absolute position measurement covers one mechanical revolution because the encoder is a single-turn encoder. A frame size of 131 mm combined with motor length code B provides a compact package with torque capacity suitable for mid-range axes. The electromagnetic winding uses code 0200, which indicates the electrical winding configuration used with a compatible drive controller. The insulation system has a thermal class of 155, allowing it to withstand winding temperatures associated with continuous operation. The motor can operate at ambient temperatures from 0 to 40 °C without derating. Its keyway shaft and accurate position feedback support applications that require stable torque transfer and controlled movement under changing loads.
