Product Description:

The MSK100A-0300-NN-S2-AG0-RNNN is a synchronous servo motor produced by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. The unit converts three-phase electrical power into precise shaft rotation, allowing packaging stations, pick-and-place gantries, and general handling axes to maintain repeatable positional accuracy in automated production cells. It is suited for servo applications that require controlled starts, stops, and direction changes during fast production cycles. The motor also uses increased concentricity for smoother rotation, a plain shaft for precision couplings, no holding brake to reduce inertia, an A-side power connector, and an A-length housing.

It relies on natural convection to remove heat from the stator, so unobstructed airflow must surround the fins during operation. Feedback travels through the EnDat2.1 digital encoder link, which provides absolute position data to the drive without extra analog wiring. The encoder creates 2048 signal periods per mechanical turn, and when interpolated this supports fine velocity regulation at low speed. Because it is single-turn, position is tracked only within one revolution, so the axis must be referenced again after multiple turns. A sealed frame rated IP65 blocks dust and low-pressure water, which allows installation close to process lines and other machine areas where contamination can be present.

The measuring system uses an optical scanning method that avoids magnetic hysteresis and works with the size code 100 electromagnetic stack to help keep cogging torque low. This combination supports smooth motion during indexing, contouring, and other tasks that depend on steady low-speed behavior. The winding uses class 155 insulation, and continuous operation is permitted within an ambient range of 0 to 40 °C when cooling air can circulate freely around the housing. Winding code 0300 sets the resistance and inductance values expected by compatible Rexroth drive amplifiers, and the balanced rotor geometry supports smooth running on tightly packed multi-axis plates without adding unnecessary bearing load.
