Frameless Permanent Magnet Alternators

Moog offers a wide selection of alternators for a variety of power generation applications. The AG Matrix™ Series alternators utilize high energy rare earth magnets and dense slot fills to achieve higher AC ouput power.

Along with our standard Matrix alternators, our engineers design custom solutions. If our existing models don’t meet your needs, we will tailor them or provide options for a best value solution to meet your exact requirements. Simply contact our experts to get started.


AG Matrix™ Series

The AG Matrix™ Series alternators are used in applications that require high power density. The designs are optimized for maximum output power and maximum efficiency. Utilizing high energy rare earth magnets and dense slot fills, the AG Series achieves higher AC output power. This provides the highest performance per volume and minimizes the alternators footprint within the system.

The alternators are supplied as a direct drive rotor / stator frameless part set that is directly attached to the load. This form of attachment eliminates backlash and increases stiffness for an optimized direct drive system.

The AG Matrix™ Series is a family of alternators consisting of a wide range of sizes, outside diameters from 5.25 to 22 inches (133.35 mm to 558.8 mm) with multiple stack sizes and winding options for each diameter.
