Abstract:
An electric machine including a stator that is provided with at least one exciter unit including a coil, at least two annular yokes and at least one row of intermediate pieces, and a rotor having a structure and at least one receiver unit including at least two series of at least two rows of magnets. Two sides of each yoke include the first teeth, fitting with the intermediate pieces on a face of the exciter unit and alternatingly forming the second north poles and the second south poles. Each series is positioned opposite one face, forming an air gap with the exciter unit, with the electric machine thus including at least two air gaps, with a flux thus circulating inside the electric machine, dividing and regrouping itself in the vicinity of the magnets and of the yokes.
