Abstract
The utility model relates to a motor cooling device used for an electric bicycle, which comprises a motor main body, a rotor shaft, a front cover and a rear cover. A brush holder is arranged in the rear cover; the rotor shaft extends out of the rear cover, and the rear end of the rotor shaft is fixed with a cooling fan; a protective cover is arranged outside the cooling fan; the end face of the protective cover is provided with a first air inlet; the end face of the rear cover is provided with a second air inlet; and air outlets are arranged on the rear cover at the circumferential direction. When a high-power DC motor is in overload working, the motor is not easily burnt down under the high temperature, and the service life is prolonged.
Description
Technical field
The utility model relates to a kind of electric motor car, relates in particular to a kind of motor of electric motor car heat abstractor.
Background technology
Along with rising suddenly and sharply of gas price, electric motor car is more and more liked by common people.The two-wheeled battery vehicle has been substituted motorcycle in the inside, city, has both saved the energy, has reduced the pollution of air again.This electric motor car provides the energy drives motor by storage battery, and electric motor car is when walking, and motor is heating/cooling device in addition.In daily life, common people are usually overloaded, and excess load is used electric motor car, and the motor torque increases, and produces a large amount of heats.Thereby cause motor to damage.
The utility model content
In order to overcome the phenomenon that the existing easy high temperature of high power DC electric machine burns out, the utility model provides a kind of electric vehicle heat abstractor.
In order to overcome the defective that exists in the background technology; the technical scheme that its technical problem that solves the utility model adopts is: a kind of motor of electric motor car heat abstractor; comprise motor main body, armature spindle, protecgulum, bonnet; be provided with brush holder in the bonnet; described armature spindle stretches out the back cover back-end and is fixed with cooling fan, and cooling fan is outside equipped with protective cover, and the protective cover end face offers first air inlet; the bonnet end face is provided with second air inlet, and the bonnet circumferencial direction offers air outlet.
Described air outlet evenly is arranged on the bonnet circumferential surface.
Described air outlet has 2 at least.
Second air inlet is linear distribution at the bonnet end face.
The utility model has solved the defective that exists in the background technology, wind inlet of fan and air outlet distance are little, air output is big, the brush holder temperature of motor is reduced rapidly, and the heat that motor body and coil windings produce is few, can lower the temperature voluntarily when being exercised by electric motor car, need not to add in addition fan cooled, especially to using high power DC electric machine when working overloadingly, motor is difficult for high temperature and burns, and prolong useful life.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of preferred embodiment of the present utility model;
Wherein: 1, motor main body, 2, armature spindle, 3, protecgulum, 4, bonnet, 5, brush holder, 6, cooling fan, 7, protective cover, 8, first air inlet, 9, second air inlet, 10, air outlet.
Embodiment
With preferred embodiment the utility model is described in further detail in conjunction with the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
As shown in Figure 1; a kind of motor of electric motor car heat abstractor; comprise motor main body 1; armature spindle 2; protecgulum 3; bonnet 4; be provided with brush holder 5 in the bonnet 4; described armature spindle 2 stretches out bonnet 4 rear ends and is fixed with cooling fan 6; cooling fan 6 is outside equipped with protective cover 7; protective cover 7 end faces offer first air inlet 8; bonnet 4 end faces are provided with second air inlet 9, and bonnet 4 circumferencial directions offer air outlet 10, also are provided with carbon brush in the bonnet 4; parts such as commutator; cooling air enters from first air inlet 8; through second air inlet 9, come out from air outlet 10, in time cool motors brush holder 5; carbon brush; parts such as commutator.Preferred second air inlet 9 of the utility model is linear distribution at bonnet 4 end faces, improves component efficiencies such as cooling brush holder 5, carbon brush, commutator.In addition, air outlet 10 evenly is arranged on bonnet 4 circumferential surfaces, and air outlet 10 has 2 at least.
Second air inlet and air outlet distance are little, and air output is big, and brush holder 5 temperature of motor are reduced rapidly.The heat that motor body 1 and coil windings produce is few, can lower the temperature voluntarily when being exercised by electric motor car, need not to add in addition fan cooled, and especially to using high power DC electric machine when working overloadingly, motor is difficult for high temperature and burns, and prolong useful life.
With above-mentioned foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the specification, must determine its technical scope according to the claim scope.
