1. A transverse magnetic flux motor comprising:
a stator, comprising a stator yoke a plurality of stator teeth arranged at intervals along a circumferential direction of the stator yoke, the stator yoke comprising a plurality of stator yoke punching sheets laminated in an axial direction of the stator yoke, and each of the plurality of stator teeth comprising a plurality of stator teeth punching sheets with a same shape laminated in a radial direction of the stator yoke, the plurality of the stator teeth being fixed on one side of the stator yoke in the axial direction of the stator yoke, and a plurality of stator windings provided on the stator yoke; and
a rotor, arranged on the one side of the stator yoke near the plurality of stator teeth in the axial direction of the stator yoke, the rotor comprising a back iron and a plurality of permanent magnets arranged in sequence along the circumferential direction of the stator yoke, each of the plurality of permanent magnets being magnetized along the axial direction of the stator yoke, and polarities of adjacent permanent magnets of the plurality of permanent magnets being different from one another,
wherein the stator yoke is provided with a plurality of open slots, wherein the number of the plurality of open slots is equal to the number of the plurality of stator teeth, and one end of each of the plurality of stator teeth along the axial direction of the stator yoke is correspondingly inserted into a respective open slot of the plurality of open slots, and
wherein the stator yoke is substantially of a ring shape, and each open slot of the plurality of open slots is opened on an inner side of the stator yoke, extends along the radial direction of the stator yoke towards an outer side of the stator yoke, and arranged between adjacent stator windings of the plurality of stator windings.
