Description

A kind of motor dispelling the heat

Technical field

The utility model relates to motor technology field, relates in particular to a kind of motor dispelling the heat.

Background technology

Existing motor generates heat because of the copper loss of stator iron loss or stator coil in operation process, electric tools is ready for use on stator heat is distributed to housing or extraneous air.

For consequent heat is distributed as early as possible, prior art adopts heat radiation interlayer, but the interlayer that dispels the heat uses for a long time, can reduce the elasticity of heat radiation interlayer, and the adhesion of cause thus dispelling the heat interlayer and housing, causes radiating effect poor.

Utility model content

The utility model is by a kind of motor dispelling the heat is provided, and then improved the radiating effect of motor.

In order to solve the problems of the technologies described above, the technical scheme of the utility model embodiment is as follows:

The motor dispelling the heat, comprising:

Ring-type stator, described ring-type stator comprises the multiple teeth along arc surface, on described multiple teeth, is wound with coil;

Rotor, is arranged on the arc surface inside of stator, and two ends of rotor face becomes chamfering with the angle that side forms;

Controller, connects described coil, is used to described coil that electric current is provided;

Housing, is coated on outside described ring-type stator and rotor, and housing two ends arrange end cap;

Cooling fin, is arranged on peripheral side in housing, and extends to housing end plug along rotor center axis direction;

Heat-conducting layer, is arranged between stator and cooling fin.

Further, described cooling fin in the form of a ring structure be arranged in order.

Further, described circulus becomes preset angles with described stator periphery.

The one or more technical schemes that provide in the utility model embodiment, at least have following technique effect or advantage:

Because the angle that in this motor that can dispel the heat, multiplied each other in two ends of rotor face and side is arranged to chamfering structure, in housing, circumferentially survey cooling fin is set, and extend to housing end plug along this central axial direction, heat-conducting layer is arranged between stator and cooling fin, fully dispel the heat, and then improved the radiating effect of motor.

Fig. 2 is the structural representation of cooling fin and heat-conducting layer in the utility model embodiment.

Detailed description of the invention

The utility model embodiment is by a kind of motor dispelling the heat is provided, and then improved the radiating effect of motor.

In order to solve the problems of the technologies described above, below in conjunction with Figure of description and concrete embodiment, technique scheme is described in detail.

The utility model embodiment provides a kind of motor dispelling the heat, and as shown in Figure 1, comprises ring-type stator 10, rotor 20, controller 30, housing 40, cooling fin 50, heat-conducting layer 60.

Concrete, this ring-type stator 10 comprises multiple teeth of arc surface, on the plurality of tooth, be wound with coil, this rotor 20 is arranged on the arc surface inside of ring-type stator 10, and the angle that these rotor 20 both ends of the surface and side form is chamfering, like this, can ensure that chamfering and other electro-mechanical parts are mutually close time, can ensure to have insulation distance, avoid short circuit and spark etc. problem.

The coil that controller 30 connects on this ring-type stator 10, thus for coil provides electric current, be the electric current that coil provides just because of this controller, make this motor produce a large amount of heats, cannot shed, will affect the normal work of motor.

Therefore, have housing 40 at ring-type stator 10 and rotor 20 arranged outside, housing 40 two ends arrange end cap. Be provided with cooling fin 50 in the interior peripheral side of housing 40, this cooling fin 50 extends to housing 40 end caps along rotor 20 central axial direction. Ring-type stator 10 can fully be dispelled the heat under the effect of this cooling fin 50, between this ring-type stator 10 and cooling fin 50, be also provided with heat-conducting layer 60, this heat-conducting layer 60 has electrical insulating property, the heat at these ring-type stator 10 places can be passed to cooling fin 50, is dispelled the heat away by this cooling fin 50. Thereby improve radiating effect.

Concrete, this cooling fin 50 circlewise structure is arranged in order, and this circulus and 60 circular arc weeks of heat-conducting layer are preset angles, for example, become 120 degree or 170 degree etc., as shown in Figure 2. Thereby the area of dissipation that has increased cooling fin 50, has effectively improved radiating effect.

Although described preferred embodiment of the present utility model, once those skilled in the art obtain the basic creative concept of cicada, can make other change and amendment to these embodiment. So claims are intended to be interpreted as comprising preferred embodiment and fall into all changes and the amendment of the utility model scope.

Obviously, those skilled in the art can carry out various changes and modification and not depart from spirit and scope of the present utility model the utility model. Like this, if these amendments of the present utility model and within modification belongs to the scope of the utility model claim and equivalent technologies thereof, the utility model is also intended to comprise these changes and modification interior.
