<p>An alternator and motor devices are disclosed of the type which are synchronous electrical generators and motors which do not require any brushes, slip rings, commutators, or permanent magnets. The various configurations of the invention have an architecture which is fundamentally binary in nature, including an even number of excitable field coils and a like number of armature or working coils. The excitation field coils and armature coils are wound around individual salient poles of the fixed stator assembly. Thus, the total number of stator poles must be a multiple of the number four (4). A rotor is constructed of a nonmagnetic material that has no salient poles, and carries a number of circumferential links of permeable magnetic material which sequentially complete flux circuits through the stator poles in alternating directions of the armature coils. The appropriate number of rotor links is equal to the number of field coils for single phase applications, and the number of rotor links is varied with respect to the number of field coils for multiple phase applications.</p> |
