Description

A kind of ceiling-fan motor

[technical field]

The utility model relates to a kind of ceiling-fan motor.

[background technology]

The design of prior motor shell louvre, just rely on the natural up and down thermal cycle of air and the purpose that extraneous heat-shift reaches heat radiation, such design is unfavorable for the circulation of motor internal air, do not reach desirable effect, cause the temperature rise of whole motor too high, useful life is not long, and the general producer can only prolong the motor purpose in useful life to reach by the cost of expanded motor manufacturing.

The utility model has carried out useful improvement with regard to above shortcoming.

[utility model content]

The purpose of this utility model is to overcome the deficiencies in the prior art part, and the ceiling-fan motor that a kind of simplicity of design, result of ventilating heat dissipation are strong, the life-span is long is provided.

A kind of ceiling-fan motor, comprise motor shaft, casing, be arranged on stator in the casing and rotor, stator is sleeved on the motor shaft outside, outside stator, be with the rotor that matches with it, rotor by the two bearings device on motor shaft, it is characterized in that casing is made up of upper casing, lower casing, be respectively equipped with a plurality of louvres on upper casing, lower casing, louvre comprises inclined open and wind deflector, and the inclined open of a plurality of louvres is towards same direction of rotation.

Aforesaid a kind of ceiling-fan motor is characterized in that a plurality of louvres are on same circumference.

Aforesaid a kind of ceiling-fan motor is characterized in that a plurality of louvres are on different circumference.

Aforesaid a kind of ceiling-fan motor is characterized in that the protruding upper casing of wind deflector of a plurality of louvres, the surface of lower casing.

Aforesaid a kind of ceiling-fan motor is characterized in that the wind deflector of a plurality of louvres inwardly puts in the surface of upper casing, lower casing.

Aforesaid a kind of ceiling-fan motor is characterized in that wind deflector can be oblique straight plate.

Aforesaid a kind of ceiling-fan motor is characterized in that wind deflector can be half pot of shape.

Aforesaid a kind of ceiling-fan motor is characterized in that stator is inlayed by stator core and coil windings to form.

Aforesaid a kind of ceiling-fan motor is characterized in that having air gap between described stator and the rotor, the hole that also is respectively equipped with along the circumferential direction on upper casing, lower casing and aligns with the position of air gap.

The purpose of this utility model is to realize like this; Because the casing of motor is made up of upper casing, lower casing, and the inclined open of a plurality of louvres on the upper casing, lower casing is all towards same direction of rotation, therefore, upper casing and lower casing assemble the direction of inclined open of its louvre of back, and consistent to become direction opposite by original direction, when motor rotates along clockwise direction, louvre forced air inlet on the upper casing, after motor internal circulation again through the louvre air-out of lower casing; When motor rotated in the counterclockwise direction, the louvre on the lower casing can mandatory air intake, again by the louvre air-out of upper casing, reached the effect of forced ventilation heat radiation after the motor internal circulation.Therefore, no matter be that clockwise direction rotates or counterclockwise rotate the effect that can reach the forced ventilation heat radiation.

[embodiment]

The utility model will be further described below in conjunction with accompanying drawing and embodiment:

As Figure 1-3, a kind of ceiling-fan motor, comprise motor shaft 1, casing 2, be arranged on stator 3 in the casing 2 and rotor 4, stator 3 is sleeved on motor shaft 1 outside, outside stator 3, be with the rotor 4 that matches with it, rotor 4 installs on motor shaft 1 by two bearings 5, casing 2 is made up of upper casing 21, lower casing 22, on upper casing 21, lower casing 22, be respectively equipped with a plurality of louvres 23, louvre comprises inclined open 231 and wind deflector 232, and the inclined open 231 of a plurality of louvres 23 is towards same direction of rotation.

A plurality of louvres 23 on the utility model upper casing 21, the lower casing 22 can be arranged on same circumference or the different circumference, and the shape of louvre can be various, and changeable, quantity is indefinite.

As shown in Figure 3, the wind deflector 232 protruding upper casings 21 of a plurality of louvres 23 on upper casing 21, the lower casing 22, the surface of lower casing 22.

Shown in Fig. 4,5, the wind deflector 232 of a plurality of louvres 23 on upper casing 21, the lower casing 22 inwardly puts in the surface of upper casing 21, lower casing 22.

Wind deflector 232 is oblique straight plate or half pot of shape.

Stator 3 is inlayed by stator core 31 and coil windings 32 and is formed; Between stator 3 and rotor 4, there is air gap 6, the hole 7 that on upper casing 21, lower casing 22, also is respectively equipped with along the circumferential direction and aligns with air gap 6.

Shown in Fig. 6,8, because the casing 2 of motor is made up of upper casing 21, lower casing 22, and the inclined open 231 of a plurality of louvres 23 on the upper casing 21, lower casing 22 is all towards same direction of rotation, therefore, upper casing 21 and lower casing 22 assemble the direction of inclined open 231 of its louvre of back, and consistent to become direction opposite by original direction, when motor rotates along clockwise direction, louvre 23 forced air inlets on the upper casing 21, after motor internal circulation again through louvre 23 air-out of lower casing 22; Shown in Fig. 7,9, when motor rotated in the counterclockwise direction, the louvre 23 on the lower casing 22 can mandatory air intake, again by louvre 23 air-out of upper casing 21, reached the effect of forced ventilation heat radiation after the motor internal circulation.Therefore, no matter be that clockwise direction rotates or counterclockwise rotate the effect that can reach the forced ventilation heat radiation.
