Product Description:

The MAC090C-0-GD-4-C/110-A-1/WI538LX is a brushless AC servo motor developed by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. It is built to deliver precise torque and speed regulation in industrial automation systems that rely on analog velocity and position commands in packaging, handling, and general machine axes. Typical roles include indexing conveyors, pick-and-place heads, and actuators where repeatable motion is required during frequent starts, stops, and positioning moves.

Mechanical integration is aided by a centering pilot of 110 mm, which aligns the flange with gearboxes and machine frames without shims or alignment plates during mounting. Thermal limits are handled through natural convection, so no external blower or liquid circuit is needed when free air circulation is available around the housing. Winding code GD indicates the copper fill, resistance, and current ratings used with mid-range drive amplifiers in this motor type. Power is routed through a connector on side A, letting cable ducts remain inside the machine envelope and keeping cable exit orientation predictable during installation. Because it is a motor for analog drives, command references are interpreted directly from ±10 V or current-loop amplifiers without digital fieldbus conversion.

Motion feedback is provided through tacho feedback with an incremental or absolute encoder, allowing either velocity-based control with a tacho generator or position tracking when absolute sensing is installed, depending on the selected feedback package. The standard build supplies an incremental encoder with standard mounting, providing 2.5 Vpp signals to legacy controllers that use sine-wave feedback inputs for stable interpolation. A standard blocking brake is included to hold the shaft when power is removed during pauses or controlled stops. The motor also uses standard tacho quality for uniform speed detection across typical analog drive applications and closed-loop speed regulation.
