Product Description:

The MSK100D-0300-NN-S2-BG0-RSNN synchronous servo motor is built by Bosch Rexroth Indramat and belongs to the MSK IndraDyn S Synchronous Motors series. Intended for industrial automation axes, the unit converts drive-controller output into precise rotary motion for packaging, material-handling, and CNC positioning tasks. It uses internal rare-earth magnets and tight mechanical tolerances to deliver high torque density with accurate speed and position control. The design is also suited for applications that must meet explosion-protected area requirements.

Winding code 0300 identifies the electromagnetic characteristics and the voltage-current relationship required from the matching drive. A frame size of 100 gives the stator a larger cross-section for heat dissipation, while the D-length housing extends the active stack to support higher continuous torque. Cooling is handled through natural convection, so heat leaves the motor surface without fans or liquid lines and installation stays mechanically simple. Power enters on the B-side, which helps keep the connector away from driven machinery and supports cleaner cable routing. Torque is transmitted through a plain shaft that mates with couplings or pulleys without keys, which helps reduce concentricity errors in the drivetrain.

Position feedback is produced by an optical encoder with the EnDat2.1 digital interface, giving the drive controller high-resolution bidirectional data exchange and electronic nameplate functions. The encoder provides 2048 signal periods, and the single-turn system reports absolute position within one mechanical revolution. The encoder is mounted on a bearing system intended for increased concentricity, and the overall motor design is certified for explosion-protected zones in flammable-gas areas. The motor is supplied without a holding brake, so a stopped position must be maintained by external mechanical restraint or by drive-generated torque when power is removed.
