Product Description:

The MAC090C-0-GD-4-C/110-A-2/WI520LV is an AC servo motor produced by Bosch Rexroth Indramat and belongs to the MAC AC Servo Motors series. It is built for closed-loop motion tasks where precise torque and velocity control are required in assembly cells, packaging stations, material-handling axes, and other machines that rely on repeatable motion. When paired with an analog drive controller, the motor supplies continuous rotary power while the drive regulates current to meet commanded speed or position profiles in industrial automation, including repeat-indexing stations and coordinated transfer axes.

Internally identified by winding code GD, the electromagnetic layout sets the voltage constant and current range for this size 090 frame. A centering diameter of 110 mm fits standard gearbox flanges, helping maintain shaft alignment during load reversals. Heat is removed through natural convection, so airflow around the aluminum body is sufficient without fans or liquid jackets. An integrated heavy-duty blocking brake holds the rotor during power-off or emergency-stop events, preventing vertical loads from drifting. Electrical power reaches the stator through a keyed connector positioned on side A, permitting cable routing that clears the brake hardware and the feedback connection at the opposite end.

Velocity feedback is generated by the built-in tacho feedback with an incremental or absolute encoder, giving the drive both speed data and reference pulses for synchronization. The primary position channel uses an incremental encoder with standard mounting, allowing use in systems where traditional line-driver signals are expected for interface compatibility. Classified as a motor for analog drives, it interfaces with voltage or current-loop command signals rather than digital fieldbus protocols, which suits older machine cells and analog control architectures. Consistent speed regulation is supported by standard tacho quality, which is adequate for mid-bandwidth servo loops that must limit overshoot without raising controller gains excessively during routine speed changes.
