WINDMILL STATOR Russian patent published in 2010 - IPC F03D9/00 

FIELD: engines and pumps.

SUBSTANCE: invention relates to wind power engineering and can be used in wind-driven generators with, primarily, low-speed windwheels. Wind-driven generator stator comprises coil, excitation source and magnetic cores. The latter are fitted on coil arranged in plane parallel to those of windwheel rotation. Note here that air gaps in magnetic cores are oriented in opposite directions from coil center to its periphery.

EFFECT: ease of manufacture thanks to applying coil-type windings and shunting one of magnetic cores (windwheel stopped) to rule out magnetic flux reduction in another core, higher emf efficiency.
