Product Description:

The MAC093B-0-GS-3-C/110-B-0 belongs to the MAC AC Servo Motors series manufactured by Bosch Rexroth Indramat. It is a compact rotary actuator for analog drive systems that require stable speed regulation and repeatable positioning in processing lines, feeders, and light machine-tool axes. The GS winding supports the electrical characteristics expected by compatible amplifiers, while the integrated tacho arrangement gives the controller the feedback needed for smooth response during changing loads. This makes the unit suitable for equipment that still uses current-controlled amplifiers rather than fully digital servo platforms.

The motor uses size code 093, which gives it a housing diameter suited to medium-duty flange patterns. Length code B indicates a moderate stack length that helps balance torque output with manageable inertia for responsive motion. Rated speed reaches 4000 rpm, allowing fast shaft rotation for transfer and handling tasks in analog servo applications. A centering diameter of 110 mm supports accurate concentric mounting on adapter plates and helps limit radial runout at the coupling. Cooling is done through natural convection, so the motor does not require an external fan and can operate in installations that rely on passive airflow.

Velocity feedback is provided by tacho feedback and a second shaft end, which gives the controller a direct speed reference and allows related components to be coupled at the rear of the motor. The tacho generates 1.5 V/1000 rpm, making scaling straightforward for analog control circuits. Power conductors terminate on a connector on side B, which helps separate power routing from other machine wiring. The motor is supplied without a blocking brake, so any holding function must be handled by drive torque or by an external mechanical device when the axis is stopped. Because the brake is absent, vertical or suspended loads need a separate holding method during power-off conditions.
