Product Description:

The MAC090B-0-PD-4-C/110-B-1/WI522LV is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Designed for analog drives, it converts drive-controller commands into mechanical rotation for positioning or speed-controlled tasks in industrial automation cells and machine tools. The unit delivers precise torque response while integrating with legacy analog amplifiers that still remain in service on many production lines. This arrangement suits retrofit systems and established machine platforms where analog control hardware is still used and predictable servo behavior is required.

Mechanical interface dimensions start with a centering diameter of 110 mm, allowing accurate seating on gearbox or machine flanges without additional alignment rings. Thermal energy is removed solely by natural convection, so airflow around the housing must remain unobstructed to maintain rated performance. During closed-loop operation, the rotor can run continuously at a nominal speed of 1500 rpm, which suits moderate-speed axes that prioritize torque linearity over high-end speed. Power enters through a plug located on side B of the housing, which simplifies cable routing in cabinets that place drives opposite the motor shaft. For velocity feedback, the internal tacho generator produces 3 V/1000 rpm, giving the drive controller an analog signal proportional to the actual shaft speed. Its mounting and cable orientation also help when the motor is installed on compact axes with limited clearance around the drive end.

In addition to the tacho channel, the motor carries an incremental encoder mounted in the standard position to supply digital position information when tighter accuracy is required. The PD winding provides the phase resistance and inductance expected by MAC-compatible analog amplifiers. Load holding during power loss is provided by the standard blocking brake, eliminating the need for external clamping on vertical axes. The motor uses a standard tacho quality rating, providing repeatable speed signals across the stated temperature range. This combination allows the motor to support applications that need analog speed regulation and separate position monitoring without external feedback hardware.
