Motor precision it is higher, the gap deviation between rotor and stator is smaller, and the concentricity of such stator and rotor is higher, more great Cheng
The vibration of degree reduced when rotor rotates, and vibrate generated noise；And the stator then can be wrapped up effectively
In in shell and air exclusion, avoids and corroded by extraneous factor, to improve service life.
Preferably, the shell is provided with plastic packaging rear end cap.
By using above-mentioned technical proposal, plastic packaging rear end cap is to play lid after rotor is pressed into shell and close sealing
Component, rotor can be resisted in the open at one end of shell, the fixed effect of limit is played to rotor.
Preferably, the stator includes enameled wire, and the enameled wire is provided with power supply line.
By using above-mentioned technical proposal, the power supply line can power on, so that the enameled wire being attached thereto is powered,
Enameled wire after energization can generate magnetic field.
Preferably, the silicon steel sheet is connect with the enameled wire, and insulating layer is provided between silicon steel sheet and enameled wire.
By using above-mentioned technical proposal, silicon steel sheet is connect with enameled wire, and the magnetic field that enameled wire generates after energization can be by silicon
Steel disc is transmitted to rotor, so that rotor is made to realize rotation, and the insulating layer can completely cut off silicon steel sheet and enameled wire, and playing prevents
The effect that silicon steel sheet is powered.
Preferably, the shell is that BMC material is molded and goes out.
By using above-mentioned technical proposal, BMC material is called tubular molding compound, have water-fast and solvent, it is heat-resisting, be not easy it is old
The properties such as change, can be improved the service life of motor.
Compared with the prior art, the advantages of the present invention are as follows: (1) shell Full-plastics sealed integrated injection molding, compared to fission
The precision of assembling is higher, so that stator is higher with rotor concentricity；It is provided simultaneously with earthing effect, ensure that Household electric appliance safety mark
Quasi- versatility；(2) stator and shell Full-plastics sealed integrated injection molding so that stator and air exclusion, avoid by it is extraneous because
Element is corroded.
