Title
(EN) A HYBRID RADIAL-AXIAL MOTOR
(FR) MOTEUR HYBRIDE RADIAL-AXIAL
Abstract
(EN) An electric machine may include a housing that encloses both a radial motor producing radial flux in a first direction, the radial flux influences a first magnetic unit to produce a first torque on a rotor arm attached to a shaft. The housing can also include an axial motor producing axial flux in a second direction to influence a second magnetic unit to produce a second torque on the rotor arm attached to the shaft, wherein the radial motor and the axial motor are positioned in the housing to reduce cross magnetic flux from either the radial motor or the axial motor. The primary radial motor can include either a permanent magnetic motor or an induction motor. The secondary radial motor can include one of a permanent magnet motor, an induction motor, or a transverse flux motor. The current and phase of primary and secondary motors can be independently controllable.
(FR) La présente invention concerne une machine électrique qui peut comprendre un boîtier qui renferme un moteur radial produisant un flux radial dans une première direction, le flux radial influençant une première unité magnétique pour produire un premier couple sur un bras de rotor fixé à un arbre. Le boîtier peut également comprendre un moteur axial produisant un flux axial dans une seconde direction pour influencer une seconde unité magnétique afin de produire un second couple sur le bras de rotor fixé à l'arbre, le moteur radial et le moteur axial étant positionnés dans le boîtier pour réduire le flux magnétique transversal provenant du moteur radial ou du moteur axial. Le moteur radial primaire peut comprendre un moteur à aimant permanent ou un moteur à induction. Le moteur radial secondaire peut comprendre un moteur à aimant permanent, un moteur à induction ou un moteur à flux transversal. Le courant et la phase des moteurs primaire et secondaire peuvent être commandés indépendamment.
