Problems solved by technology

[0002] In the related art, since the stator assembly of the motor is arranged outside the rotor assembly in a closed ring shape, when the rotor assembly of the motor needs to be disassembled and separated from the stator assembly, it can only be disassembled and separated along the axial direction of the rotor assembly. In the application scenario, since the rotor assembly is usually connected to the output end of the motor, due to the influence of the installation environment, in the case of small space in the axial direction, before disassembling the rotor assembly, it is necessary to connect the output end of the motor The driving parts are removed first, or the stator assembly in the motor is disassembled first when the motor casing is opened, resulting in more time-consuming and laborious daily maintenance of the motor. How to quickly separate the rotor assembly and stator assembly of the motor has become an urgent problem to be solved

Embodiment 1

[0073] Such as Figure 1 to Figure 9 As shown, the motor according to the embodiment of the first aspect of the present invention includes a rotor assembly 100 and a stator assembly 200 .

[0074] Wherein, the stator assembly 200 has a mating surface matched with the rotor assembly 100, and the mating surface is arranged opposite to a part of the outer peripheral surface of the rotor assembly 100, so that the rotor assembly 100 can be aligned with the stator assembly 200 along its radial direction and / or axial direction. separate.

[0075] In this embodiment, an electric machine is provided that includes a rotor assembly 100 and a stator assembly 200 . Wherein, the stator assembly 200 is located outside the rotor assembly 100, and the surface of the stator assembly 200 that matches the rotor assembly 100 is a mating surface, and the mating surface is arranged opposite to a part of the outer peripheral surface of the rotor assembly 100, that is, the stator assembly 200 does no...

Embodiment 2

[0088] Such as Figure 1 to Figure 5 As shown, in one embodiment of the present invention, optionally, the number of the stator assembly 200 is one, and the stator assembly 200 includes: a stator core 210 with stator teeth 212 thereon; at least two stator windings 214, at least two The stator windings 214 are respectively arranged on the stator teeth.

[0089] In this embodiment, based on the fact that the number of the stator assembly 200 is one, the stator assembly 200 includes a stator core 210 and at least two stator windings 214, the stator core 210 has stator teeth 212, and the at least two stator windings 214 are respectively Arranged on the stator teeth 212 , at least two stator windings 214 can generate a magnetic field when energized, so that the rotor assembly 100 rotates under the action of the magnetic field.

[0090] In any of the above embodiments, optionally, there are multiple stator assemblies 200 , and the plurality of stator assemblies 200 are combined or ...

Embodiment 3

[0105] Such as Figure 1 to Figure 5 As shown, in any of the above embodiments, optionally, the number of stator teeth 212 is greater than or equal to three, and the polarities of the stator windings 214 on any two adjacent stator teeth 212 are different.

[0106]In this embodiment, when the number of stator teeth 212 is greater than or equal to three, it is preferable to energize the two adjacent stator windings 214 together, and make the polarities of the two adjacent windings reverse, so that the rotor assembly 100 is subjected to a force in a tangential direction, so as to provide power for the rotation of the rotor assembly 100 .

[0107] Specifically, when the number of stator teeth 212 is set to three, the first stator winding 214 and the second stator winding 214 are energized, and the first stator winding 214 generates an N-pole magnetic field to S of the magnetic member 160 in the rotor assembly 100. Pole attraction, the second stator winding 214 generates an S pole...

Abstract

The invention provides a motor, a motor assembly, a food processor, an air supply device and a household appliance. The motor comprises a rotor assembly; a stator assembly which is provided with a matching surface matched with the rotor assembly, wherein the matching surface is arranged opposite to part of the peripheral surface of the rotor assembly, so that the rotor assembly can be separated from the stator assembly in the radial direction and / or the axial direction of the rotor assembly. According to the motor provided by the invention, the rotor assembly can be separated from the stator assembly along the radial direction and / or the axial direction, so that the stator assembly and the rotor assembly in the motor are more convenient to disassemble and assemble, the subsequent daily maintenance of the motor is facilitated, and the rotor assembly and a driven part can be integrally arranged; therefore, the motor provided by the invention is simpler in product structure, and the rotorassembly can be conveniently separated from the stator assembly, thereby achieving the quick disassembly of a driven part.
