Product Description:

The MSK100A-0300-NN-S1-BG0-NNNN is an AC servo motor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It serves as the mechanical output stage of a drive, supplying regulated torque and speed to automated handling units, forming presses, and similar industrial axes. When paired with a compatible Rexroth inverter, the motor operates in a closed-loop motion system that supports accurate positioning, steady speed control, and repeatable cycle behavior. This arrangement is useful in machinery that must accelerate quickly, reverse direction precisely, and hold a commanded path under changing load conditions.

With a frame size of 100, the motor provides a medium mechanical footprint matched to winding code 0300, which corresponds to electrical characteristics suited to general-purpose motion tasks. An optical single-turn encoder delivers 128 signal periods per revolution over the Hiperface interface, allowing the controller to monitor rotor position for commutation and positioning functions. The housing carries a protection rating of IP65, so internal components are protected against dust ingress and water jets in typical industrial environments. The motor uses a standard design with length code A, which keeps the package compact while still supporting continuous operation in space-limited machine assemblies.

Cooling relies on natural convection, eliminating the need for fans or external coolant lines and simplifying installation where additional cooling hardware is not desired. Safe operation is maintained between 0–40 °C, and insulation class 155 helps the winding system withstand normal thermal loading during extended duty. The motor uses a plain shaft for direct coupling, and its power connector is located on side B, which can simplify cable routing when access is restricted on the opposite face. Because the unit is supplied without a holding brake, any static load retention must be handled by drive torque or by a separate mechanical locking device.
