Product Description:

The MSK100A-0300-NN-S1-BG1-NNNN is a synchronous servo motor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It is intended for closed-loop positioning and speed control in industrial automation. When paired with an IndraDrive amplifier, the motor moves packaging, printing, and material-handling axes with high accuracy and repeatability. This operating role makes it suitable for applications that require precise starts, stops, and controlled speed changes during continuous machine operation.

Heat generated during operation is removed by natural convection, so no external fan or liquid circuit is required. The power connector is located on the B-side of the housing, which helps route cables away from the driven load. A plain shaft works with keyless hub components to reduce runout and vibration during rotation. The motor includes an electrically released holding brake that secures the load during power-off states, and the brake can hold up to 32 Nm of static torque. Motor size 100 and length A give the unit a compact housing for medium-frame installations without supplemental cooling hardware.

Rotor position is read through a Hiperface encoder that provides 128 signal periods per revolution. This optical feedback supports tight servo loops while keeping the wiring arrangement relatively simple. Because the encoder is single-turn, it reports absolute position within one mechanical revolution and relies on the controller to track additional turns. The motor uses winding code 0300, which matches its electrical characteristics to the corresponding drive module for rated torque output. This combination of feedback, brake, shaft style, and cooling supports stable service in indexing tables, gantry axes, and other precision motion systems.
