Embodiment Construction
[0017] Such as Figure 1 to Figure 4 As shown, a bicycle dual-rotor motor 10 provided according to the first preferred embodiment of the present invention is in the form of a mid-mounted motor of an electric bicycle, and mainly consists of a housing 11, a stator assembly 21 and a The rotor assembly 31 is composed of:
[0018] The stator assembly 21 and the rotor assembly 31 are disposed in the casing 11 .
[0019] The stator assembly 21 has a stator base 22 fixed on the housing 11, and a coil ring 24 fixed on the stator base 22, the coil ring 24 is provided with a multi-phase winding 25 distributed along its circumference, and the The multi-phase winding 25 is circularly wound along the radial direction of the coil ring 24 . In the first embodiment, the coil ring 24 of the stator assembly 21 is formed by stacking a plurality of silicon steel sheets, and the multi-phase winding 25 is a three-phase winding as an example. FIG. 3(A) shows the coil ring 24 around which the U-pha...
