A direct drive rotary generator formed of an elongate cylindrical series of stator annuli and a coaxial elongate cylindrical series of armature annuli and mounted for relative rotational movement around their common axis, the series of stator annuli interleaving the series of armature annuli, and either of the armature/stator annuli having a contiguous or substantially contiguous sequence of coils around its circumference, and the other of the armature/stator annuli having a corresponding sequence of permanent magnets of alternating polarity spaced around its circumference and at the same pitch as that of the coils, the arrangement being such that lines of magnetic flux passing across the air gap between one magnet carrying annulus to the next cut the turns of the coils of the corresponding interleaved coil carrying annulus, and thus induce in the coils electromagnetic forces as the armature is caused to rotate relative to the stator. |
