The invention relates to a synchronous or direct current heteropolar electric machine inductor with permanent magnets made of ferrites or other hard magnetic materials, and represents an improvement invention of the RO patent 115208 According to the invention, the inductor is characterized in that, with a view to maximally using the magnetic flux of the permanent magnets, for more efficiently using the available space in a given building, there are manufactured one or more permanent magnets (1a), (1b), (1c) of a circular shape for the inner inductor and of a circular crown shape for the outer inductor, with different radial sizes, located in cascade, having axial magnetization, so that the "North" type pole pieces (2) and "South" type pole pieces (3) have variable flux sections, increasing in cascade in the air gap direction as the flux collected from the permanent magnets (1a), (1b), (1c) increases, for the same purpose, the inductor being extended axially as against the armature length by adding two front configurations of permanent magnets and pole pieces (11) into the inductor package, which can provide further concentration of the magnetic flux
