An electric machine (100) is disclosed in this patent application. The electric machine (100) comprises a rotor portion (10) and a stator portion (60). The rotor portion (60) comprises a plurality of magnets (37). The stator portion (60) comprises a plurality of electromagnetic poles (57) located at the external perimeter of the stator (60). A conductive winding (68) is wrapped around the stator poles (57). The stator (60) is ideally formed in an annular shape from laminated substrates. The rotor (10) and stator (60) are located in a common housing (20). A hub (110) retains the stator (60) to a frame. When the conductive winding (57) is energized with an electric current, temporary magnetic poles form around the stator poles (57). The rotor (10) is located opposite the stator (60) and separated by an air gap. The rotor (10) rotates around the stator (60) by electromagnetic forces. A machine controller (80) controls the operation of the electric machine (100).

La présente invention concerne une machine électrique (100) comprenant une partie de rotor (10) et une partie de stator (60). La partie de rotor (10) comprend une pluralité d'aimants (37). La partie de stator (60) comprend une pluralité de pôles électromagnétiques (57) situés sur le périmètre externe du stator (60). Un enroulement conducteur (68) est enroulé autour des pôles de stator (57). Le stator (60) présente idéalement une forme annulaire et est constitué de substrats stratifiés. Le rotor (10) et le stator (60) se trouvent dans un boîtier commun (20). Un moyeu (110) retient le stator (60) sur un cadre. Lorsque l'enroulement conducteur (57) est mis sous tension avec un courant électrique, des pôles magnétiques temporaires se forment autour des pôles de stator (57). Le rotor (10) est situé à l'opposé du stator (60) et ceux-ci sont séparés par un entrefer. Le rotor (10) tourne autour du stator (60) grâce à des forces électromagnétiques. Un contrôleur de machine (80) contrôle le fonctionnement de la machine électrique (100).
