A polyphasic 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 electrically conductive coils mounted to the stator in a first angular orientation about the drive shaft. The rotors each have an array of magnets which are circumferentially equally spaced around the rotor and located at the same radially spacing with respect to the centre of the rotor and the drive shaft at a first angular orientation relative to the drive shaft. The arrays of magnets on adjacent rotors are off-set by an angular offset relative to one another.
