Abstract (en)

[origin: WO2021245568A1] An electric machine with permanent magnets comprises at least two rotors (2-5) mutually coaxial and each provided with two or more permanent magnetic poles associated with their side wall, at least one stator (10-12) provided with windings with respective electrical output contacts (13-15) and interposed between two of said rotors (2-5) to be powered with current and generate a rotating electromagnetic field adapted to put into rotation the corresponding rotors (2-5), a transmission shaft (16) mechanically connected to said rotors (2-5) to be driven into rotation upon the rotation of said rotors (2-5) promoted by said at least one stator (10-12).
