Patent ID: 8766501

Claim:
A direct current rotating electrical machine, the machine comprising: a stator ( 3 ) comprising a magnetized structure with permanent magnetization extending along a circumference of the stator; a rotor ( 2 ); and a group of brushes ( 13 , 14 ) arranged to allow the electrical supply of the rotor by switching the electrical current in sections of the rotor, the magnetized structure ( 5 ) of the stator including at least one sector between two consecutive magnetic poles (N; S) of the magnetized structure, the at least one sector having a magnetization direction varying essentially sinusoidally along the circumference of the stator ( 3 ); an angular displacement of a neutral line selected so as to improve switching when the electrical machine is in operation; the magnetized structure ( 5 ) including at least two magnets ( 150 ); at least one of the magnetic poles (N; S) of the magnetized structure ( 5 ) positioned at a circumferential end ( 151 ) of one of the magnets; the magnetization direction within the one of the magnets on the circumferential end thereof being substantially radial; the electrical machine comprising a number Nb of the poles; the magnetized structure ( 5 ) including a number Nb of the magnets, arranged adjacent to each other.
