Abstract
A stator-and-rotor structure and an axial magnetic field motor are provided. The stator-and-rotor structure is a dual-stator and dual-rotor structure. Permanent magnets of the outer rotor is fixed on a rotor yoke portion, the inner rotor has no rotor yoke portion, permanent magnets of the inner rotor is fixed on a rotor support, the inner stator core has no stator yoke portion, and the outer stator core has a stator yoke portion.
Claims17
A stator-and-rotor structure, comprising a first rotor, a first stator, a second rotor and a second stator sequentially disposed at intervals in an axial direction, wherein the first rotor comprises a first rotor yoke portion and a plurality of first rotor permanent magnets disposed at circumferential intervals on a side of the first rotor yoke portion facing the first stator, the second rotor comprises a non-magnetic permeable second rotor support and a plurality of second rotor permanent magnets disposed at circumferential intervals on the second rotor support, the first stator comprises a first stator core comprising a plurality of first stator core tooth portions disposed at circumferential intervals, the second stator comprises a second stator core comprising a second stator core yoke portion and a plurality of second stator core tooth portions disposed at circumferential intervals on a side of the second stator core yoke portion facing the second rotor, and an axial closed-loop magnetic path is formed between the first rotor yoke portion and the second stator core yoke portion.
