Product Description:

The MAC090C-0-KD-4-C/110-B-0/WI511LV/S001 is produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed as a motor for analog drives, it provides closed-loop torque and speed control for index tables, handling axes, and general-purpose positioning modules in industrial automation. Its mechanical interface, feedback devices, and electrical winding are coordinated so that legacy servo amplifiers can regulate motion without additional adaptation circuitry.

This model clamps onto a machine frame through a centering pilot of 110 mm, a dimension that aligns the housing concentrically with gearboxes or coupling flanges. Heat generated in the stator is removed by natural convection; no fan is installed, so mounting orientation and ambient airflow become important for continuous duty. The rotor reaches a nominal speed of 1500 rpm, giving moderate output frequency for drives that must synchronize with mechanical transmissions. Power conductors terminate through a connector on side B, allowing cable entry opposite the output shaft and simplifying wiring inside compact cabinets. For speed feedback, the built-in tacho generator outputs 3 V/1000 rpm, a level scaled for standard analog velocity loops.

Position feedback is handled by an incremental encoder that shares the same mechanical seat as the tacho, enabling commutation and fine motion interpolation from a single encoder flange. The presence of integrated tacho feedback supports legacy controllers that rely on dual-channel velocity and position signals. A stator wound with the designated KD winding sets the motor’s electrical resistance and inductance so drive converters can supply rated current without saturation. The motor ships without a blocking brake, so holding torque during power-off must be provided by external clamps or by gravity-neutral load designs.
