A three-phase permanent magnet electric motor-generator includes a stator having a plurality of teeth, each provided with a respective electric winding implemented by a conducting wire and with a respective heading polar expansion, divided into groups each one corresponding to a phase, by obtaining at the same time a reduced short-circuit current. The distance between adjacent polar expansions is the minimum one so as to allow the passage of a conducting wire. By identifying a first magnetic circuit comprising two adjacent teeth, the respective rotor and stator yokes, the thicknesses of the respective permanent magnets and the corresponding air gap, and a second magnetic circuit having two adjacent teeth, the respective rotor yokes, the respective halves of the faced polar expansions of said adjacent teeth and the distance between such polar expansions, the magnetic reluctances of the first and second circuit have the same order of magnitude.
