However, the inner hole of the rotor is formed by injection molding, and has certain shrinkage deformation, when the inner hole of the rotor is large, the rotor is easy to move left and right and up and down due to high rotor rotation speed, so that the noise of the motor is caused, and particularly when the motor is reversely mounted, the noise caused by the up and down movement of the rotor under the action of gravity is more obvious;
the other type is that the structure is assembled by adopting a machine shell, a central rotor rod, a bottom gasket, a rotor, a machine shell surface cover and the like in a matching way, and the structure is mainly characterized in that the height of the rotor is flush with the surface cover or is 0.1-0.2 mm lower than the height of the surface cover, the structure reduces the noise of vertical movement to a certain extent, but because the distance between the rotor and the surface cover is too close, the motor is easy to press the rotor if the motor is riveted deeply when the cover is sealed and riveted, the motor fails, meanwhile, the top of the rotor is close to the surface cover and easily generates friction sound with the surface cover, and the structure can not carve the rotor sound caused by injection molding deformation of the rotor and large inner hole.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a synchronous machine's rotor amortization structure, through addding top gasket and spring, the spring of reasonable elasticity is controlled the upper and lower of central rotor pole effectively and is moved, give the reasonable pressure of rotor simultaneously and effectively overcome because of the central rotor contracts the hole and leads to the rotor to produce about leaping up the noise problem of moving greatly, thereby can effectively overcome through top gasket and drive the spring rotation and produce the problem of friction sound with the apron because of the high-speed rotation of rotor, thereby the rotor that has solved current synchronous machine and used easily because it is big partially to mould plastics the shrink hole and the rotor top produces the problem of friction sound with the face lid relatively very easily.
