Abstract
An axial flux rotary generator comprising: two magnetic annuli; a coil annulus; the magnetic annuli and coil annulus having a common axis; the two magnetic annuli defining a plurality of magnetic fields around the common axis extending across a gap between the two magnetic annuli and the coil annulus having a sequence of coils around the common axis in the gap such that lines of magnetic flux from the magnetic fields cut the turns of the coils and thus induce electric current in the coils as the magnetic annuli are caused to rotate relative to the coil annulus, means provided at or towards the central aperture of the coil annulus axial to resist flexure of the coil annulus.

An axial flux rotary generator comprising:
- two magnetic annuli;
- a coil annulus mechanically braced at an outside periphery;
- the magnetic annuli and coil annulus having a common axis;
- the two magnetic annuli defining a plurality of magnetic fields around the common axis extending across a gap between the two magnetic annuli and the coil annulus having a sequence of coils around the common axis in the gap such that lines of magnetic flux from the magnetic fields cut the turns of the coils and thus induce electric current in the coils as the magnetic annuli are caused to rotate relative to the coil annulus;
- and
- means provided at the central aperture of the coil annulus to resist axial flexure of the coil annulus.
