Product Description:
The MSK101D-0450-NN-S2-AG3-RNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat and supplied within the MSK IndraDyn S Synchronous Motors series. In automated lines, it delivers closed-loop torque and velocity so that positioning tables, gantries, or tool spindles can follow controller commands with high repeatability. The motor’s increased concentricity design improves shaft runout, allowing tight mechanical tolerances to be maintained between the motor and coupled loads without additional alignment devices.
The unit cools through natural convection, removing heat via its housing fins and eliminating the need for forced air or liquid circuits. Motion is secured at power-off by an electrically released brake that supplies 120 Nm of static holding torque. An IP65 enclosure helps keep dust and low-pressure water jets out of the frame so the motor can be mounted directly on machinery without a separate protective cabinet. Position data are transmitted over the EnDat 2.1 interface, and the optical feedback system provides 2048 signal periods per revolution to support high-resolution interpolation in the drive controller.
The motor operates between 0–40 °C, matching typical factory floor temperatures, and its insulation system is rated to 155, permitting continuous winding temperatures up to 155 °C without loss of dielectric strength. Mechanical dimensions follow size code 101 with a length designation D, giving the motor a known frame format for machine integration. Power leads exit on the A-side to simplify cable routing toward the cabinet, and winding code 0450 indicates the electrical characteristics used by the matching drive. A plain shaft provides smooth coupling to gearboxes or direct-drive hubs, while the single-turn optical encoder reports absolute position for each revolution without multi-turn counting circuitry.
