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...

Abstract

The invention discloses a dual-rotor motor for a bike, which comprises a shell. the shell is internally provided with a stator assembly and a rotor assembly; the stator assembly is provided with a stator seat and a coil ring fixedly arranged on the stator seat; the coil ring is provided with a multi-phase winding distributed along the circumference; the rotor assembly is provided with a rotor fixing seat, an inner rotor and an outer rotor; the inner rotor and the outer rotor are ring-shaped and fixedly arranged on the rotor fixing seat and a preset distance is left between the inner rotor and the outer rotor; the opposite surfaces of the inner rotor and the outer rotor are respectively provided with multiple inner magnets and multiple outer magnets; the same poles of the inner magnets and the outer magnets are opposite to each other; and the coil ring and the multi-phase winding are located between the inner magnets and the outer magnets.

Description

technical field [0001] The present invention relates to motors, in particular to a dual-rotor motor for bicycles. Background technique [0002] The known mid-mounted motor for bicycles has low motor power and insufficient thrust. Moreover, the volume is relatively large, resulting in difficulties in design and installation. In addition, the known mid-mounted motor for bicycles uses more materials (such as silicon steel sheets and copper wire windings), which makes the cost high. All of these are subject to improvement. Contents of the invention [0003] The main purpose of the present invention is to provide a dual-rotor motor for bicycles, which has a smaller volume and higher motor power than known motors, thereby not only providing higher thrust, but also enabling design and Installation is easier. [0004] Another object of the present invention is to provide a dual-rotor motor for a bicycle, which can reduce the use of materials and further reduce the cost. [00...
