Product Description:

The MSK100A-0200-NN-S1-BG0-NNNN is an AC synchronous servo motor built by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. Within a drive system, this motor serves as the electromechanical element that delivers closed-loop rotary motion to positioning tables, gantries, and process rollers. Its brushless design, paired with an integrated optical encoder, allows the connected drive amplifier to regulate torque and speed with high accuracy while keeping the motor compact enough for tightly packed machine frames. This arrangement supports precise motion control in automated equipment where stable speed regulation and repeatable positioning are required during continuous operation.

Heat generated in the stator is removed by natural convection, so no auxiliary fan or liquid circuit is required, and installation must allow free vertical airflow around the housing. Elastomer seals and a machined end bell give the unit an IP65 rating, which helps protect internal components from dust and low-pressure water exposure. Rotor position is reported through a Hiperface interface, and the measuring system provides 128 signal periods per mechanical revolution. The optical scanning principle resists magnetic interference and supports precise interpolation inside the drive controller for smooth velocity control and stable commutation.

The encoder delivers absolute data in single-turn format, so it reports one unique position value for each revolution and is suitable for axes that reference at startup. Continuous operation is permitted at ambient temperatures from 0 to 40 °C, and the insulation system has class 155 to support elevated winding temperatures during normal use. Drive torque is transmitted through a plain shaft, which supports direct coupling to precision gearheads and similar driven elements. The power plug is located on the B-side to help keep cable routing clear of adjacent machine parts, and the motor uses frame size 100 with the compact A length in a standard design. The unit is supplied without a holding brake, so any load that must remain fixed after power removal requires an external locking method.
