Abstract

The utility model provides a motor. The traditional motor has problems of that the dust prevention and radiation effects are poor. The motor of the utility model comprises a base, a stator fixed on the and a rotor arranged in the stator. A dirt cover is also arranged outside the stator. An impeller is connected with a rotation shaft of the rotor at one end of the rotor. In the motor, the cover opening of the dust cover is provided with a reinforcing rib. The impeller comprises a trumpet-shaped basal body which is provided with a plurality of blades. The blades are vertical to the basal body. The motor of the utility model greatly improves the dust prevention and radiation effects.

Description

A kind of motor

Technical field

The utility model relates to motor, relates in particular to the motor of AC/DC, in products such as water pump.

Background technology

Traditional motor generally is made of base, stator and the rotor that is positioned at stator.The problem that the motor of this structure exists is: dustproof weak effect.And, therefore, also exist the problem of heat radiation because motor when high speed rotating, can produce a large amount of heats.

The utility model content

Therefore, the purpose of this utility model is, a kind of motor of novel structure is provided, and it has preferable radiating effect and dustproof effect, makes electronic function adapt to different operational environments better, prolongs the useful life of motor.

According to above-mentioned purpose, the motor that the utility model provides comprises: base, be fixed on the stator on the described base and be arranged at rotor in the stator, it is characterized in that described stator also is provided with dust cover outward, at an end of described rotor, be connected with a fan blade with the rotating shaft of described rotor.

In above-mentioned motor, be provided with reinforcement at the cover mouth of described dust cover.

In above-mentioned motor, described fan blade comprises a loud-speaker shape matrix, and matrix is provided with a plurality of blades, and described blade is vertical with matrix.

As mentioned above, the utility model improves the dust cover structure and the radiator structure of motor, has improved dustproof and radiating effect greatly.

Embodiment

The overall structure of motor of the present utility model is at first described referring to Fig. 1.

As shown in Figure 1, motor of the present utility model comprises: base 10, stator 20, rotor 30, dust cover 40 and fan blade 50.Stator 20 is fixed on the supporting seat 11 of base 20 by screw rod 12, and rotor 30 is positioned at stator 20, the rotating shaft 31 protruding bases 10 of rotor 30.Dust cover 40 is installed in the end of motor with respect to base 10, in the outside of dust cover 40 fan blade 50 is installed then.Fan blade 50 is fixed to by nut 13 in the rotating shaft 31 of rotor 30, so, when rotor 31 rotates, will drive fan blade 50 and rotate together, plays the effect of exhausting, thereby motor is dispelled the heat.

The structure of dust cover 40 as shown in Figure 2, wherein, Fig. 2 A is a cutaway view, Fig. 2 B is the right view of Fig. 2 A.As can be seen from Figure 2A, dust cover 40 roughly comprises overskirt 41 and cover mouthful 42 two parts.Overskirt 41 is used to cover the exposed parts of stator 20 and rotor 30.Outside cover mouth 42, be provided with reinforcement 43.Be generally and reduce cost, dust cover 40 is generally all used plastic production, and therefore, dust cover 40 is comparatively soft, and intensity is less, and the effect of this reinforcement 43 is exactly in order to strengthen its intensity.

The structure of fan blade 50 as shown in Figure 3, wherein, Fig. 3 A is a cutaway view, Fig. 3 B is the right view of Fig. 3 A; Fig. 3 C is the left view of Fig. 3 A.As can be seen from Figure 3A, the matrix 51 of fan blade 50 is a loud-speaker shape, and the back of loud-speaker shape is provided with a plurality of blades 52, and these blades 52 are vertical substantially with matrix 51.There is a through hole 53 in central authorities at loud-speaker shape matrix 51, and this through hole 53 is used to be installed to the rotating shaft 31 of rotor 30.Can also be provided with stiffener 55 between the sidewall 54 of through hole 53 and the matrix 51, improve the intensity of fan blade with integral body.

When fan blade 50 rotates with rotor 30, vertical blade 52 will produce outside wind turning (exhausting), force the air of motor interior outwards to flow, thereby take the heat owing to motor rotation generation of its inside out of.Through test of many times, the fan blade of exhausting formula is better than the bleed type fan blade on radiating effect.In the utility model, fan blade 50 also can adopt plastic material to make, to improve fail safe.

In addition, it should be noted that also that the reinforcement 43 at dust cover 40 cover mouthful 42 places also helps the exhausting of fan blade 50 simultaneously.

Please be simultaneously referring to Fig. 1 and Fig. 2, on constituting, motor of the present utility model comprises: base 10, stator 20 and rotor with traditional the same.Stator 20 is fixed on the base 10 by supporting seat 30, and rotor is installed in the stator 20, Gu fail to illustrate in Fig. 1.Among Fig. 1 label be 40 be electrode, it is with stator 20 and change and be electrically connected, to provide electric power to motor.

Main improvement of the present utility model is the shape of base 10.As shown in Figure 1, the base 10 in the utility model comprises two parts, disk 11 and square plate 12.Offer shaft hole 13 on the disk 11, shaft hole 13 is stretched out in the rotating shaft 50 of rotor, and the distance setting between the center of circle 14 of this shaft hole 13 and disk 11 is 31.5 ± 0.5 millimeters.This distance obtains noise when so spacing distance can greatly reduce motor operation and vibration through experiment many times.

Claims (3)

1, a kind of motor comprises: base, be fixed on the stator on the described base and be arranged at rotor in the stator, it is characterized in that described stator also is provided with dust cover outward, at an end of described rotor, be connected with a fan blade with the rotating shaft of described rotor.

2, motor as claimed in claim 1 is characterized in that, is provided with reinforcement at the cover mouth of described dust cover.

3, motor as claimed in claim 1 or 2 is characterized in that, described fan blade comprises a loud-speaker shape matrix, and matrix is provided with a plurality of blades, and described blade is vertical with matrix.
