Product Description:

The MAC090A-0-RD-2-C/110-B-1 is an AC servo motor built by Bosch Rexroth Indramat and assigned to the MAC AC Servo Motors series. As an electromechanical actuator, it converts drive current into controlled rotary motion for positioning tasks on analog axis controllers in presses, machine tools, and material-handling stations. The motor closes its speed loop through tacho feedback, so the controller receives real-time speed information during operation. That makes the motor suitable for retrofit machinery where analog motion hardware is already in service.

As a motor for analog drives, the unit accepts proportional command voltages from legacy servo amplifiers rather than fieldbus traffic. Heat is removed through natural convection, so no external blower or liquid circuit is required, and some open space above the housing helps warm air escape. The flange has a centering recess of 110 mm, which supports concentric alignment with mating machine parts during installation. This helps preserve shaft alignment and reduces the chance of coupling stress caused by mounting offset. A blocking brake holds the shaft when power is removed, helping prevent unintended movement on vertical axes or in applications where the load must remain in place.

Power conductors terminate through a connector on side B, placing the cable exit opposite the output shaft and simplifying routing in compact cabinets. The motor uses standard tacho quality, which suits applications that need stable speed feedback without extremely fine speed resolution. The brake and cable position also help when the motor is installed on compact vertical or horizontal axes. Its mounting and electrical layout follow the platform used for this product family, so it can be integrated with related analog drive hardware and common machine interfaces.
