Abstract

The utility model discloses a shaded-pole alternating current motor with low noise and high efficiency. The shaded-pole alternating current motor with low noise and high efficiency comprises a stator (1), a rotor (2), a front end cover (3), a rear end cover (4), wherein the front end cover (3) and the rear end cover (4) are respectively fixedly connected on both ends of the stator (1), a rotating shaft (2-1) of the rotor (2) is rotatablely supported on the front end cover (3) and the rear end cover (4) through a bearing (5), an air gap exists between the stator (1) and the rotor (2), the bearing (5) is with low noise and a small clearance, a fit mode of clearance fit is adopted between an excircle of the rotating shaft (2-1) and an innercircle of the bearing (5), the air gap between the stator (1) and the rotor (2) is 0.3 mm. The shaded-pole alternating current motor with low noise and high efficiency can reduce noise, improve work efficiency of the shaded-pole alternating current motor and prolong service life of the bearing.

Description

The split-pole alternating current motor of low noise efficient rate

Technical field

The utility model relates to a kind of split-pole alternating current motor of low noise efficient rate, belongs to the motor manufacturing technology field.

Background technology

At present; The split-pole alternating current motor is widely used in the small household appliances such as electric fan, hair dryer, dust catcher, in people's life, use more and more wider, so wide application; Big consumption like this; Make the technology upgrading of split-pole alternating current motor that considerable economic arranged, but the noise of split-pole alternating current motor is restricting its development with inefficient problem always, using to the user and brought inconvenience.

Summary of the invention

The purpose of the utility model provides a kind of split-pole alternating current motor with low noise and greater efficiency.

The technical scheme that realizes the utility model purpose is: a kind of split-pole alternating current motor of low noise efficient rate; It comprises stator, rotor, front end housing and rear end cap; Front end housing and rear end cap are fixedly connected on the two ends of stator respectively; The rotating shaft of rotor can be rotated to support on front end housing and the rear end cap through bearing, has air gap between rotor and the stator, and described bearing is the little play bearing of low noise; Cooperating between the cylindrical of described rotating shaft and the inner ring of bearing is matched in clearance, and the air gap between rotor and the stator is 0.3 millimeter.

Further, all have some the radiating ribs that are uniformly distributed with on the lateral surface of described front end housing and rear end cap.

After having adopted technique scheme, the use of the little play bearing of low noise has reduced the noise that causes because of bearing effectively; Rotating shaft is used matched in clearance with cooperating of bearing, avoided because the damage of the bearing that cooperates tension to cause has increased the useful life of bearing, and can be at the low noise that to a certain degree descends; It is 0.3 millimeter that air gap between rotor and the stator changes little, has reduced the excitatory loss of motor, thereby has improved electric efficiency; The design of radiating ribs can improve the radiating effect of front end housing and rear end cap, thereby has reduced the heat radiation loss of motor, and the operating efficiency of motor further is provided.

Embodiment

For the content that makes the utility model is expressly understood more easily, below according to specific embodiment and combine accompanying drawing, the utility model is done further detailed explanation,

As shown in Figure 1; A kind of split-pole alternating current motor of low noise efficient rate; It comprises stator 1, rotor 2, front end housing 3 and rear end cap 4, and front end housing 3 and rear end cap 4 are fixedly connected on the two ends of stator 1 respectively, and the rotating shaft 2-1 of rotor 2 can be rotated to support on front end housing and the rear end cap 4 through bearing 5; Has air gap between rotor 2 and the stator 1; Described bearing 5 is the little play bearing of low noise, and cooperating between the inner ring of the cylindrical of described rotating shaft 2-1 and bearing 5 is matched in clearance, and the air gap between rotor 2 and the stator 1 is 0.3 millimeter.All have some the radiating ribs that are uniformly distributed with 6 on the lateral surface of described front end housing 3 and rear end cap 4.

The operation principle of the utility model is following:

The use of the little play bearing of low noise has reduced the noise that causes because of bearing 5 effectively; Rotating shaft 2-1 uses matched in clearance with cooperating of bearing 5, avoided because bearing 5 damages that cooperate tension to cause have increased the useful life of bearing 5, and can be at the low noise that to a certain degree descends; It is 0.3 millimeter that air gap between rotor 2 and the stator 1 changes little, has reduced the excitatory loss of motor, thereby has improved electric efficiency; The design of radiating ribs 6 can improve the radiating effect of front end housing 3 and rear end cap 4, thereby has reduced the heat radiation loss of motor, and the operating efficiency of motor further is provided.

Above-described specific embodiment; Purpose, technical scheme and beneficial effect to the utility model have carried out further explain, it should be understood that the above is merely the specific embodiment of the utility model; Be not limited to the utility model; All within the spirit and principle of the utility model, any modification of being made, be equal to replacement, improvement etc., all should be included within the protection range of the utility model.
