Product Description:

The MAC093B-0-JS-4-C/130-A-1/WI517LV is an AC servo motor manufactured by Bosch Rexroth Indramat and belongs to the MAC AC Servo Motors series. Intended for analog drives, it delivers precise torque and speed regulation in industrial automation lines such as positioning tables, pick-and-place stations, and conveyor modules. Closed-loop operation is supported by integrated tachogenerator and encoder signals, so the drive amplifier can maintain commanded motion profiles when load conditions change. This arrangement is useful on axes that require repeatable starts, stops, and stable speed correction throughout the operating cycle.

This B-length frame uses winding code JS, which matches the stator's electrical characteristics to compatible drive amplifiers. Heat dissipates by natural convection, so the housing depends on surrounding airflow rather than forced cooling. Alignment to gearboxes or machine frames is handled by a 130 mm centering diameter, and the overall envelope matches size 093 used in the series. Under nominal excitation, the rotor reaches 3000 rpm, which supports responsive operation on mid-inertia axes. The tachogenerator supplies a stable speed signal that helps the analog control loop respond smoothly during acceleration, deceleration, and changing load conditions.

A standard blocking brake locks the shaft when power is removed, which helps prevent unwanted movement on vertical or suspended axes. The tacho winding produces 3 V/1000 rpm velocity feedback, while an incremental encoder provides position data for the connected drive. Using both speed and position feedback allows the amplifier to correct small motion errors without separate sensing hardware at the machine. Power conductors exit through a connector on side A, which simplifies cable routing where the motor is mounted close to guards or machine frames. The brake also helps keep the axis stationary during shutdowns and idle periods.
