Product Description:

The MSK100D-0300-NN-S2-BG0-RNNN is manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It uses frame size 100, length code D, and winding code 0300. Deployed in material-handling axes, packaging stations, and general motion cells, this IndraDyn S servomotor converts drive current into controlled rotary movement while reporting absolute position to the controller. Accurate torque and speed regulation allow the axis to synchronize with neighboring drives inside automated assemblies.

Its thermal management relies on natural convection, so installation must allow unobstructed airflow around the housing to remove heat without auxiliary fans or liquid jackets. Position data are provided by an EnDat2.1 serial encoder interface, giving bidirectional communication for parameter downloads and diagnostics. The optical scale delivers 2048 signal periods per mechanical revolution, and the optical scanning principle ensures high signal quality with minimal hysteresis. Because the encoder is single-turn, it outputs an absolute position within one revolution; applications that move beyond one turn must rely on the drive’s electronic gearing or an external homing routine.

Mechanical construction follows the increased concentricity design to minimize radial runout and simplify alignment of couplings. The power connector is mounted on the B-side, which lets cable runs exit parallel to the mounting flange and keeps clearance available on the opposite face. Drive torque is transmitted through a plain shaft, eliminating keyway stresses when clamp couplings are used. The motor ships without a holding brake, so any static load must be secured by the drive’s current loop or by an external brake module. This manufacturing class helps maintain low vibration levels when the rotor accelerates or decelerates during high-precision positioning sequences.
