ABSTRACT:
Lack of axial compactness in a dynamoelectric machine is avoided in an axial gap dynamoelectric machine including a disc (62, 66) rotatable about an axis (56) and adapted to be coupled to a shaft (54). At least two equally angularly spaced magnets (74, 76, 78, 80, 84, 86) are mounted on the disc (62, 66) and have their poles (N,S) facing in axial directions. A stator (72) is axially spaced but in close adjacency to the magnets (74, 76, 78, 80, 84, 86) and includes at least two equally angularly spaced groups of windings (92, 94, 96, 98). Each of the winding groups (92, 94, 96, 98) includes first and second winding loops (102, 104) with one of the loops (104) being wholly within the other of the loops (102) and in a common plane therewith.
