Product Description:

The MSK100A-0300-NN-M1-AG0-NNNN is a synchronous servo motor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It converts drive controller output into tightly regulated rotary motion for position-, speed-, and torque-controlled axes in automated machinery. This model occupies the 100 frame class with a length A housing, giving machine installations a compact source of continuous torque without external cooling hardware. Its synchronous design supports controlled acceleration, stable running, and accurate stopping in indexing, packaging, and material-handling applications.

The motor sheds heat through natural convection, so airflow around the housing is sufficient for steady-state operation when sizing follows the published load and torque curves. Feedback is supplied through the Hiperface protocol, and the integrated encoder delivers position information with 128 signal periods. Optical scanning supports repeatable signal generation, while the multiturn absolute function keeps track of shaft position over multiple revolutions for immediate startup reference after power returns. This feedback arrangement allows the connected drive to monitor rotor position continuously during closed-loop operation. The housing has an IP65 protection rating that resists dust and low-pressure water jets, which supports use on exposed machine axes.

This variant is built without a holding brake, so static load retention must be provided by the drive or by an external mechanical device when the application requires it. A plain shaft supports direct coupling to compatible machine elements, and the A-side power connector can simplify cable routing near the control enclosure. Continuous duty is approved within an ambient range of 0-40 °C, and the windings use Class 155 insulation to support the permitted internal thermal load. Because the shaft does not include a brake assembly, the motor is best suited to axes where standstill holding is handled elsewhere in the machine design.
