Abstract
A permanent magnet apparatus () for achieving electrical performance is provided. The apparatus () includes a cylindrical stator assembly () having a plurality of stator pole assemblies () and a cylindrical rotor assembly () having a plurality of rotor pole assemblies (). Each stator pole assembly () includes a wire coil () and a laminated stack () of axially aligned stator segments (). Each of the stator segments () has a center-post portion () that is detachably engaged to a back-iron portion (). Each rotor pole assembly () is provided with a laminated stack () of axially aligned rotor segments () to which is secured a permanent magnet (). Preferably, the stator pole assemblies () are secured to a base plate () by fastening rods () and the stator assembly () includes stacks () of back-iron portions () where each stack () is positioned to abut two stator pole assemblies (). The rotor pole assemblies () are preferably secured to a rotor plate () by fastening rods () and magnet retention-stops () defined by stacked rotor segments () frictionally support the permanent magnet (). The apparatus () is most desirably operated as a low-shaft-speed, permanent magnet alternator.
