Product Description:

The MAC090C-0-GD-4-C/110-A-1/WI578LV/S01 is an AC servo motor manufactured by Bosch Rexroth Indramat as a member of the MAC AC Servo Motors series. It is intended to supply precise rotary motion for industrial automation when paired with analog drive amplifiers, where regulated current from the drive produces the torque and speed required by metal-cutting machines, packaging stations, and general handling axes. Its layout supports repeatable motion on axes that need steady speed control and consistent position response during continuous operation.

This model is built around a 110 mm centering diameter, allowing the flange to seat concentrically against standard machine housings for repeatable shaft alignment. Heat produced in the stator is removed through natural convection cooling, so no auxiliary blower or liquid circuit is necessary, and clear ambient airflow is the only requirement. Incoming three-phase power reaches the windings through a power connector on side A, simplifying cable routing in cabinets that face the motor on that side. A standard blocking brake is integrated to secure the load whenever the drive disables torque, preventing drift on vertical axes during power loss. Performance data correspond to the GD winding code, which indicates the electrical characteristics used with the MAC drive family.

Rotor speed and position are reported by a combined feedback package that supplies tacho feedback plus an incremental or absolute encoder signals, enabling either velocity-loop operation or direct position capture inside the controller. For applications that only need incremental resolution, the secondary sensor provides an incremental encoder with standard mounting, making retrofit into existing analog control loops straightforward. Velocity smoothing is aided by standard tacho quality, which keeps speed ripple within limits expected by older proportional controllers. Because it is a motor for analog drives, its signal levels, connector styles, and temperature ratings correspond to legacy Indramat amplifiers still found in many production lines. This feedback arrangement also supports integration with control systems that continue to use established analog motion hardware.
