Product Description:

The MSK100B-0450-NN-S1-AP2-NNNN belongs to the MSK IndraDyn S Synchronous Motors series from Bosch Rexroth Indramat. It is an IndraDyn S synchronous servo motor intended to deliver precise rotary motion for positioning, feed, and auxiliary axes in automated machinery and production cells. It is suited for packaging, material-handling, and similar automated systems that depend on repeatable motion. Power is fed through an A-side connector that keeps the wiring on the same face as the feedback lead.

This model relies on natural convection for heat removal, so no external blower or liquid loop is required. An electrically released holding brake supplies 70 Nm of static torque for load holding during power-off states. The motor housing carries a protection rating of IP65, allowing installation in dust-laden or splash-prone zones without additional sealing. The motor uses size code 100 with length code B for its mechanical envelope. This layout helps keep the motor compact for installation in space-limited equipment. The optical encoder uses a 128 signal periods scale and communicates through the Hiperface interface. The encoder is single-turn, so absolute position is maintained over one mechanical revolution without the need for homing after power cycles.

The permitted ambient range is 0–40 °C, matching general-purpose cabinet and open-machine environments. A keyed shaft, noted as a shaft with keyway, delivers positive drive engagement with pulleys or couplings. Thermal performance is backed by insulation class 155, allowing winding temperatures up to 155 °C before aging becomes critical. Electrical parameters are matched to winding code 0450, so a compatible drive controller can supply the required current and voltage without derating. The optical feedback system provides clean signal edges for tight velocity and position loops. That feedback arrangement also supports accurate commutation in standard servo applications.
