Abstract

A polyphasic multi-coil generator includes a driveshaft, at least first and second rotors rigidly mounted on the driveshaft so as to simultaneously synchronously rotate with rotation of the driveshaft, and at least one stator sandwiched between the first and second rotors. The stator has an aperture through which the driveshaft is rotatably journalled. A stator array on the stator has an equally radially spaced-apart array of electrically conductive coils mounted to the stator in a first angular orientation about the driveshaft. The stator array is radially spaced apart about the driveshaft. The rotors and the stator lie in substantially parallel planes. The first and second rotors have, respectively, first and second rotor arrays. The first rotor array has a first equally radially spaced apart array of magnets radially spaced around the driveshaft at a first angular orientation relative to the driveshaft. The second rotor array having a second equally spaced apart array of magnets at a second angular orientation relative to the driveshaft. The first and second angular orientations are off-set by an angular offset so that the first and second rotor arrays are offset relative to one another.
