Patent ID: 7425772

Claim:
Electric power generating system using ring-shaped generators, which comprises: at least one stator formed of, at least one ring sector ( 8 , 16 ) that has first stator elements ( 100 ) fixed to it, each stator element ( 100 ) comprising: one piece of high magnetic permeability formed, at least partially, by at least one magnet; a winding ( 2 ) around the piece of high magnetic permeability; an air gap ( 52 ) formed in the piece of high magnetic permeability; at least one rotor ( 14 ) formed by at least one ring sector attached to a turbine, a ring sector to which is fixed at least one portion of high magnetic permeability ( 5 ) arranged alternately with at least one portion of low magnetic permeability ( 4 ); wherein the rotation of the rotor ( 14 ) causes the portions of high ( 5 ) and low ( 4 ) magnetic permeability of the rotor to alternately pass the air gap ( 52 ) of each element of the stator ( 100 ), causing a variation of reluctance in the magnetic circuit formed by each stator element ( 100 ), and the portions of high ( 5 ) and low ( 4 ) magnetic permeability of the rotor ( 14 ), and inducing an e.m.f. in each one of the windings ( 2 ) of the stator elements ( 100 ).
