Product Description:

The MAC090A-0-RD-4-C/110-A-0/WI520LX belongs to the MAC AC Servo Motors series produced by Bosch Rexroth Indramat. It is an AC servo motor that converts commanded current into controlled shaft torque and speed for industrial positioning tasks. Integrated feedback supports stable closed-loop operation on transfer axes, assembly stations, and pick-and-place systems. The motor is suited to installations that require repeatable rotary motion without separate feedback hardware. It is also suitable for axes that need steady velocity control as well as repeatable position changes.

The housing uses a centering recess of 110 mm to align the motor with gearboxes or machine flanges. Cooling is handled by natural convection, so heat leaves through the housing surface without auxiliary fans or liquid circuits. Electrical power is supplied through a connector on side A, which helps route cabling away from moving machine members and can simplify cable placement in tight machine frames. Speed and position signals come from an integrated incremental encoder, allowing the drive to monitor rotor movement directly during operation. The motor is supplied without a blocking brake, so any holding force during power loss must come from external hardware.

Internal tacho feedback also supplies velocity data for the analog regulator. This channel is built to a standard tacho quality grade that matches legacy MAC controllers and supports stable speed regulation. Because the unit is a motor for analog drives, its feedback voltages and current behavior are intended to work with classic TDM and KDS drive cards. That compatibility is useful in equipment that keeps established analog control loops instead of replacing the full motion platform. It also allows the motor to serve in retrofit installations where the original drive architecture remains in service.
