Description

A kind of radiating motor

[technical field]

The utility model relates to a kind of motor, and more particularly, the utility model relates to a kind of radiating motor.

[background technology]

Motor is made up of rotor and stator two parts, is used for realizing the conversion of electric energy and mechanical energy and mechanical energy and electric energy.Whether motor normal operation, most important mark is the degree of heat of this motor, motor, in the process run, converts electrical energy into mechanical energy, along with the mutual conversion of energy, always have certain energy loss, the energy of these losses can be transformed into heat energy, and whole motor temperature is raised, and thermal accumlation will cause the reduction of built-in electrical insulation ability simultaneously, affect exerting oneself of motor, reduction of service life.Meanwhile, the rotor of existing motor generally all adopts the permanent magnet of yi word pattern, because structural being limited between two pieces of adjacent permanent magnets can cause short circuit, and be also not easy to dispel the heat.

[utility model content]

The purpose of this utility model is the shortcoming for existing in prior art, provides a kind of and provides the radiating motor that a kind of structure is simple, radiating efficiency is high.

In order to achieve the above object, the technical solution adopted in the utility model is as follows:

A kind of radiating motor, comprise stator, rotor that the lamellar body of rotating shaft and multiple circumferential array forms, described lamellar body forms the main body of rotor, this sheet outside has storage tank, inside is provided with lightening hole, be provided with linking arm between described lightening hole, the storage tank sidewall on described storage tank and this main body are in the axial direction at an angle.

Preferably, on same storage tank, described in two, storage tank sidewall is parallel to each other, and correspondingly respectively has the groove in axial direction extended, and the width of described groove is that the bottom surface of described storage tank is along 3/5 of opening direction length.

Preferably, in the axial direction at an angle, and on same linking arm, the described linking arm sidewall (10) of both sides is parallel to each other for the linking arm sidewall on described linking arm and this main body.

Preferably, the storage tank sidewall on described storage tank and be the in the axial direction angle of this main body are 10 °.

Compared with prior art, the utility model has the advantage of: because the storage tank sidewall on lamellar body and main body axis direction shape have a certain degree, in rotor turns process, accelerate the motion of fluid, significantly reduce the temperature of motor internal, there is the advantages such as structure is simple, good heat dissipation effect.

[embodiment]

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

Consult shown in Fig. 1-2, a kind of radiating motor that the utility model provides, comprise stator 2, rotor 3 that the lamellar body 4 of rotating shaft 5 and multiple circumferential array forms, lamellar body 4 forms the main body of rotor 3, and this lamellar body 4 lateral surface has storage tank 6, and inside is provided with lightening hole 7, linking arm 8 is provided with between lightening hole 7, storage tank sidewall on this storage tank 69 and this main body axis direction at an angle, this angle optimum be 10 °, also can be other angles.

Consult shown in Fig. 3, two storage tank sidewalls on same storage tank 6 are corresponding respectively has the groove in axial direction extended, width the best of this groove be the bottom surface of storage tank 6 along 3/5 of opening direction length, also can be other suitable width.Storage tank 6 is provided with permanent magnet 1, the two ends of this permanent magnet 1 snap in the groove of storage tank sidewall 9, be like this in order to, when rotor high-speed rotates, permanent magnet can not be excessive because of centrifugal force, and come off from lamellar body.The degree of depth of groove is generally 2-3mm, to closely cooperate as optimum with the two ends of permanent magnet 1.

Consult shown in Fig. 2, Fig. 4, in the axial direction at an angle, and on same linking arm, the linking arm sidewall of both sides is parallel to each other for linking arm sidewall on linking arm 8 10 and this main body.The effect of its overall structure type fan, when rotor height is rotated, adds flowing and the confusion degree of air-flow, is taken away the heat in motor, thus quickly reduce the temperature of motor by the air-flow accelerating flowing.

Although describe execution mode of the present utility model by reference to the accompanying drawings; but patent owner can make various distortion or amendment within the scope of the appended claims; as long as be no more than the protection range described by claim of the present utility model, all should within protection range of the present utility model.
