Product Description:

The MAC092B-0-QD-2-C/095-B-2/S013 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It serves as an electromechanical actuator for position and speed control loops in analog drive systems used on machine tools, packaging lines, and assembly stations. The motor converts regulated electrical current into rotary torque, allowing connected machinery to respond quickly to changing motion commands. Its design supports applications that require continuous rotation, controlled acceleration, and accurate speed regulation under varying mechanical loads.

A heavy-duty blocking brake is mounted on the shaft to prevent loads from back-driving the axis during a power loss or emergency stop. The flange has a centering diameter of 95 mm, allowing the motor to align accurately with compatible gearboxes or direct-drive fixtures without additional adapters. Heat generated by copper losses is removed through natural convection, eliminating the need for a cooling fan and reducing the number of moving components. Velocity information is provided by integrated tacho feedback, which supplies an analog voltage that changes in proportion to shaft speed for closed-loop regulation. Power conductors exit through a connector on side B, keeping the cable path consistent when the motor is installed among neighboring axes. This orientation also helps separate high-current power leads from sensitive feedback wiring within the machine.

As a motor for analog drives, the unit connects to compatible amplifiers that use a continuous tacho signal rather than digital encoder data. The drive electronics interpret the standard tacho quality output to regulate motor current without requiring an additional signal conversion device. The continuous feedback signal allows the amplifier to correct speed deviations caused by changes in load or commanded motion. Careful routing and shielding of the feedback cable can reduce electrical interference from nearby power conductors and switching equipment. The blocking brake supports stationary load retention, while the tacho circuit supplies the velocity information required during active operation. The naturally cooled housing is suitable for installations where adequate airflow is available around the motor surface.
