ABSTRACT:
A permanent magnet generator has a laminated rotor mounted to the driven shaft of a power alternator. The rotor is cylindrical and includes 10 circumferentially distributed elongated axial slots and 10 rotor teeth. Iron-boron-neodymium rare earth magnets are secured within each of the slots, radially and similarly polarized. The magnet and teeth define a consequent 20 pole rotor with a minimum number of magnets. The rare earth magnets are epoxy bonded within each of the corresponding slots. Each slot has a rectangular cross-section with slightly flared sides. The epoxy extends between the recess surfaces and the magnets. The flared sides improve the flux distribution. The outer radial ends of the magnets spaced inwardly of the rotor teeth prevent mechaical damage to the magnets. The outside maximum dimension of the PMG stator is slightly less than the inner diameter of the exciter stator for convenient removal through the bore of the exciter.
