Product Description:

The MAC092B-0-QD-3-C/095-A-0 is an AC servo motor built by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. The unit is intended for closed-loop speed and torque control in assembly lines, metal-cutting centers, and transfer stations that rely on analog velocity or current commands from legacy drive controllers. By integrating a permanent-magnet rotor and precision feedback elements, the motor provides smooth low-speed rotation and rapid acceleration, making it suitable for precise positioning tasks within industrial automation cells.

The mechanical interface uses a centering pilot of 95 mm, which aligns the motor housing to the driven machine frame and helps keep radial runout within tolerance. Thermal management is passive because stator heat is removed through natural convection; the housing fins must therefore remain exposed to ambient air, and no auxiliary fan or coolant loop is required. Speed information is generated by an internal tachogenerator, so the controller receives continuous tacho feedback proportional to shaft velocity. A factory-machined second shaft end lets the motor drive an external encoder or another mechanical element without altering the primary drive side. Power conductors leave the housing through a sealed connector mounted on side A, which helps simplify cable routing in compact cabinets.

The motor is supplied without a blocking brake, so external holding devices are required whenever static load retention during power-off is needed. Speed feedback accuracy follows the manufacturer’s Standard tacho quality grade, delivering a linear voltage response suitable for general-purpose regulation loops. Because it is classified as a motor for analog drives, the winding inductance, tachogenerator constants, and connector pinout match legacy Rexroth drive amplifiers that use voltage or current setpoints rather than digital command words.
