  • Electric machine with a rotor constructed of permanent magnets and magnetic flux guides
    Patent number: 6384504
    Abstract: An electric machine comprising a stator and a rotor (2) separated by an air gap (12), (a) the rotor (2) being composed with permanent magnets (8) magnetized substantially in circumferential direction, and with one magnetic flux conducting piece assembly (10) of at least one magnetic flux conducting piece (10a; 10b) between two adjacent permanent magnets each; (b) the permanent magnets (8)—when looking at the overall geometry—each having an increasing circumferential width from the head portion on the side of the air gap to the foot portion; (c) and the conducting piece assemblies (10) between two adjacent permanent magnets (8)—when looking at the overall geometry—each having a decreasing circumferential width from the head portion on the side of the air gap to the foot portion, characterized in (d) that the conducting pieces (10a; 10b) at the foot end each have a widened portion in circumferential direction, having at least one shoulder (20) through which they are supported on an a
