Title:
2つのロータを備えた多極モータ
Document Type and Number:
Japanese Patent JP3611923
Kind Code:
B2
Abstract:
The motor has first(3) and second(5) multi-polar coaxial rotors each having a number of magnetic dipoles(7) arranged parallel to the axis of rotation(9,11) of the rotors. Has two stator parts(13,15) and an intermediate part(17) between the first and second parts(13,15). Each part(13,15,17) has a stator opening(19,20,21) aligned with the axis of rotation of the rotors(3,5). The stator parts(13,15) have stator polar airgaps situated either side of the stator openings(19,20). The airgaps define a succession of teeth(36) and airgap(35) on the edge of the stator openings(19,20). The first rotor(3) is mounted so as to rotate between the first stator part(13) and the intermediate part(17). The dipoles(7) of the first rotor(3) are arranged with respect to the to the teeth on the first stator part(13) and to the intermediate stator part airgap. The second rotor(5) is mounted so as to rotate between the stator part(15) and the intermediate stator(17). The dipoles of the second rotor(5) are arranged with regard to the teeth on the second stator part(15) and to the intermediate stator part airgap.
