Frameless Permanent Magnet Alternators

AG Matrix™ Series

The AG Matrix™ Series brushless DC permanent alternators are used in applications that require high power density. These alternators are available in 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. The designs are optimized for maximum output power and maximum efficiency.

Benefits of Permanent Magnet Alternators

  • 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.
