Abstract

See full text

Electric machine having: a shaft; a rotor with permanent magnets that is fitted to the shaft; a stator having a magnetic core which consists of a series of laminations made of ferromagnetic material and longitudinally crossed by a plurality of stator slots; and a stator winding having a plurality of rigid bars that are inserted in corresponding stator slots and that are covered, on the outside, with an insulating coating. Each stator slot is completely free from an insulating element interposed between the ferromagnetic material making up the laminations of the magnetic core and the corresponding bars, so that an outer surface of the corresponding bars is in direct contact with an inner surface of the stator slot made of the ferromagnetic material.
