Patent

CA 2642987

A motor is provided with: an inner rotor having inner permanent magnets arranged in a peripheral direction and an outer rotor having outer permanent magnets arranged in the peripheral direction, the mutual axes of rotation of the inner rotor and the outer rotor being arranged coaxially, and a rotating device capable of making at least one of the inner rotor and the outer rotor rotate around the axes of rotation so as to change the relative phase between the rotors, wherein the rotating device includes: a first member which is integrally and rotatably provided with respect to the outer rotor; and a second member which is integrally and rotatably provided with respect to the inner rotor and which defines pressure chambers inside the inner rotor with the first member, and wherein a working fluid is supplied to the pressure chambers, thereby changing the relative phase between the rotors.

La présente invention concerne un moteur qui comprend des moyens de rotation qui possèdent un premier élément agencé en tant que bloc unitaire rotatif avec un rotor côté circonférence extérieure et un second élément agencé en tant que bloc unitaire rotatif avec un rotor côté circonférence intérieure. Le premier élément et le second élément forment une chambre de pression à l'intérieur du rotor côté circonférence intérieure. En fournissant un fluide de travail dans la chambre de pression, il est possible de changer la phase relative entre le rotor côté circonférence intérieure et le rotor côté circonférence extérieure.
