Product Description:

The MAC090C-0-GD-4-C/110-A-2/WI520LV/S018 is an AC servo motor developed by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. The unit converts command signals from drive controllers into controlled rotary motion, allowing machines to position loads or regulate speed with repeatable accuracy. It is suited to axes that need repeatable starts, stops, and speed changes without relying on open-loop motor control. By integrating electromagnetic actuation with built-in position feedback options, it serves as the rotating element in pick-and-place arms, packaging stations, and other industrial automation equipment that rely on closed-loop motion.

Winding code GD characterizes the stator’s copper fill and impedance so that the motor draws the current profile expected by legacy analog servo amplifiers. A 110 mm centering diameter provides a reference surface for concentric mounting to gearboxes or adapter plates, keeping radial runout low. Heat is removed through natural convection cooling, eliminating fans and reducing maintenance. The power cables terminate through a connector on side A, which simplifies cabinet layout by locating high-current conductors in a single direction. An integrated heavy-duty blocking brake applies mechanical holding torque during emergency stops or when vertical axes must remain stationary without continuous current.

The feedback chain uses tacho feedback with incremental or absolute encoder signals, giving drive electronics a proportional velocity reference alongside position data. This arrangement helps the controller compare actual shaft behavior with the commanded motion path during startup and normal operation. For finer resolution, the selected sensing scheme includes an incremental encoder with standard mounting, which aligns to the housing without custom flanges. The motor maintains standard tacho quality, keeping speed ripple within accepted limits for analog velocity loops. Classified as a motor for analog drives, it fits installations that use voltage or current commands rather than fully digital fieldbus communication.
