Product Description:

The MSK131D-0200-NN-S2-AP0-RNNN synchronous servomotor is built by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. Designed as a compact rotary actuator, it supplies closed-loop torque and velocity control to CNC tables, packaging stations, and material-handling axes. A keyed output shaft permits rigid coupling to gearboxes or pulleys, while the integrated encoder provides rapid position feedback to the drive controller. Within an automation cell, the motor serves as the primary electromechanical element that converts regulated current into repeatable rotary motion. This layout supports accurate acceleration, stable speed regulation, and repeatable stopping during cyclic machine operation.

Cooling is handled through natural convection, meaning heat dissipates directly to the surrounding air without fans or liquid channels, so installation must leave clearance around the housing to sustain continuous duty. The frame code 131 identifies the stator diameter, giving the motor a large magnetic cross-section for high torque, while length category D adds an extended lamination stack that increases continuous power output. Electrical characteristics are set by winding code 0200; this winding sets the voltage constant and current draw expected by the IndraDrive amplifier. Position information is communicated over the EnDat2.1 serial interface, enabling bidirectional parameter exchange and automatic electronic nameplate recognition. Passive cooling also helps the motor fit installations where auxiliary airflow is not preferred.

For fine interpolation inside the drive, the optical sensing system resolves the shaft into 2048 signal periods. Because the scale is read with an optical method, it maintains consistent accuracy over the full speed range. The feedback is a single-turn device, so absolute position is referenced within one mechanical revolution, which is useful on short-travel axes and indexing applications. An A-side power connector routes the three-phase supply toward the drive cabinet, and the increased concentricity design minimizes radial runout despite the absence of a holding brake. This arrangement supports startup with immediate position availability and keeps cable routing aligned with common cabinet layouts.
