Abstract:
An axial gap EDM deploys as a stator coils a series of two parallel serpentine windings that each circumscribe an arc segment of a circle. Each arc segment that forms the stator winding assembly is powered as a separate phase. The two winding are readily formed by shaping one or more wire segment. Preferably the parallel winding are arranged to overlap with a half period rotational offset such that the radial directed serpentine segments of that are disposed above and below the stator disk are interlaced when viewed in projection through the disk. In one embodiment, each series of serpentine winding are separated by a gap so that they can be inserted on the stator disk from the edge. A separate rotor disk is adjacent each side of this stator disk. In another embodiment, each series of serpentine winding are separated by a gap, so they can be inserted to surround a single rotor disk which has two series of magnets disposed on opposite sides.
