The present invention relates to the installation structure of the rotor and the center of gravity adjusting washer installed in the impeller for a cleaner motor that requires precise balance according to the high speed rotation of the motor, in particular, by installing a washer with a stone jaw to the impeller to rotate at high speed To maintain the balance between the impeller and the rotor, the center of gravity of the impeller is stably adjusted, and the installation structure of the center of gravity adjustment washer can be further extended to reduce the vibration of the motor to further extend the life of the cleaner motor. To provide.

In a generally known structure of a cleaner motor, the stator 2 and the rotor 3 are provided inside the motor housing 1, as shown in FIG. 1, and the motor shaft 4 is disposed at the center thereof. The commutator 5 is installed in the lower side, and the impeller 6 divided into two parts is installed in the motor cover 7 at the upper end of the motor shaft 4.

In the conventional cleaner motor having the structure as described above, the motor shaft 4 rotates to rotate the impeller 6 integrally with the rotor 3 when the rotor 3 is driven in response to the input of the power source. External air flows into the motor during the rotational operation of (6).

On the other hand, the cleaner motor is a motor shaft (4), the rotor (3) and the impeller (6) is rotated at high speed, so that the center of gravity should be adjusted to be positioned in the center, accordingly While the noise and vibration can be reduced only when the balance between the electrons 3 and the impeller 6 is maintained accurately, the impeller of the impeller is displaced by the high-speed rotation between the motor side 4 and the impeller 6. The center of gravity is not adjusted properly, there is a disadvantage that generates a severe vibration and accordingly noise.

In addition, the efficiency of the motor due to the weight center mismatch of the impeller 6 is lowered, and the life of the cleaner motor is significantly shortened, there are many problems.

The present invention is to improve the various problems of the prior art as described above, its purpose is to install a washer in the bottom of the impeller to maintain the balance of the impeller and rotor rotating at high speed accurately, the weight of the impeller The center is to be adjusted stably, of course, to reduce the vibration and noise of the motor to provide a center of gravity adjustment washer installation structure of the cleaner motor that can further extend its life.

As a technical configuration for achieving the above object, the present invention, the washer is installed on each of the motor shaft upper coupling portion and the lower coupling portion of the impeller divided into two, the washer is formed with projections on both sides, the main projection It is formed by providing a center of gravity adjustment washer to support and adjust the center of gravity of the impeller.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 2 is a plan view of the center of gravity adjusting washer according to the present invention, and FIG. 3 is a cross-sectional view taken along line AA of FIG. 2 and described in connection with FIG. 1 of the motor shaft 4 installed inside the motor housing 1. In the cleaner motor in which the commutator 5 is provided at the lower side, and the impeller 6 divided into two is installed at the upper end of the motor shaft 4 in the motor cover 7, the motor of the impeller 6 is provided. Impeller support washers 8 are respectively installed on the shaft 4 engaging portion, and the impeller support washers 8 are formed with protrusions 9 on both sides, and a protrusion 10 is formed at the upper periphery of the impeller 6. The center of gravity of the configuration is made to support the adjustment.

Referring to the operation and effects of the present invention composed of such a structure as follows.

As shown in Figs. 1 to 3, when the impeller 6 provided above the motor shaft 4 of the cleaner motor and the rotor 3 mounted integrally with the motor shaft 4 are rotated. The impeller 6 rotating at high speed has an impeller support washer mounted on the coupling portion between the lower side of the impeller 6 and the motor shaft 4 when the center of gravity is out of the motor shaft 4 due to the rotational centrifugal force. 8) to stably support the impeller (6).

The impeller support washer 8, the projections 9 are formed on both sides, the projection 10 is protrudingly installed on the upper main surface, to support the lower side of the impeller 6 divided into two is stable. Due to this, the center of gravity of the impeller 6 is stably adjusted.

In addition, by adjusting the center of gravity of the impeller (6), the balance with the rotor (3) which rotates integrally with the motor shaft (4) is also maintained in the same, so that the noise and vibration of the motor can be significantly reduced.

According to the structure of the center of gravity adjustment washer of the cleaner motor according to the present invention as described above, by installing a washer with a stone jaw to the impeller to maintain a constant balance of the impeller and the rotor rotating at high speed, the center of gravity of the impeller This stably adjusted, of course, by reducing the vibration of the motor can further extend the life of the cleaner motor.
