Abstract

The invention relates to an electrical machine comprising at least two disc rotors. Each disc rotor is equipped with a number of permanent magnets, which generate axially oriented magnetomotive forces and which are uniformly distributed over the periphery. The electrical machine also comprises a stator, which is arranged between the disc rotors and which is equipped with several coils. Said coils are uniformly distributed over the periphery, they each occupy a sector of the stator, and can be interconnected as desired in order to form at least one winding. The inventive electrical machine exhibits an improved efficiency when the stator (52) is comprised of a flat plate provided with the coils (60) on both faces since, as a result, the mass of each coil is reduced by half, yet the surface per unit of volume is enlarged. Due to the cooling that is improved thereby, the heating of the coils is diminished.
