A polyphasie multi-coil generator includes a drive shaft, at least first and second rotors rigidly mounted on the drive shaft so as to simultaneously synchronously rotate with rotation of the drive shaft, and at least one stator sandwiched between the first and second rotors. A stator array on the stator has an array of coils mounted to the stator in a first angular orientation about the drive shaft. The rotors each have an array of magnets which are equally circumferentially spaced around the rotor and located at the same radial spacing with respect to the center of the rotor and the drive shaft. The arrays of magnets on adjacent rotors are off-set by an angular off-set relative to one another.
