Abstract
The utility model discloses a motor comprising a stator housing, a front cover arranged on the stator housing, a back cover arranged on the stator housing, a rotor shaft arranged on the front cover and the back cover, a fan fixed on a back end of the rotor shaft extending out of the back cover, an air inlet arranged on the back cover, a protective hood fixed on the back end of the stator housing, and an air outlet arranged on the circumferential surface of the front cover. The motor is characterized in that ventilation grooves are arranged on the inner surface of the stator housing. The motor has the advantages of fast heat dissipation, low working temperature, and long service life.
Description
Technical field
The utility model relates to a kind of motor.
Background technology
There is not air outlet on the existing motor protecgulum, the main fin heat radiation that relies on the stator case of heat radiation, the rearmounted cooling fan motor (patent No. 200620073783.7) of patented technology electric vehicle, this patented technology has increased an air outlet at protecgulum, but between air inlet and air outlet, stopped up by stator, wind does not circulate, and radiating effect is bad.
Summary of the invention
The utility model provides a kind of motor in order to address the above problem proposition, to its objective is, this motor rapid heat dissipation, and the work temperature rise is low, long service life.
The technical scheme that adopts is: comprise stator casing 1, be installed in protecgulum 2 on the stator casing 1, be installed in bonnet 3 on the stator casing 1, be installed in armature spindle 4 on protecgulum 2 and the bonnet 3, be fixed on armature spindle 4 stretch out fan 5 on the rear end of bonnet 3, air inlet 6 built on the bonnet 3, be fixed on the guard shield 7 of stator casing 1 rear end, air outlet 8 on protecgulum 2 side faces, it is characterized in that: be shaped on ventilation slot 9 on the inner surface of stator casing 1.
Compared with prior art, the beneficial effects of the utility model are:
1, be shaped on ventilation slot 9 on the inner surface of stator casing 1, wind enters along ventilation slot 9 from air inlet 6 and flows, and flows out from air outlet 8 at last, immediately heat is taken away, and the motor rapid heat dissipation, the work temperature rise is low, long service life.
Description of drawings
Fig. 1 is the front view of motor embodiment;
Fig. 2 is the left view of stator casing;
Fig. 3 is the bonnet left view;
Fig. 4 is the guard shield left view.
Among the figure 1, stator casing, 2, protecgulum, 3, bonnet, 4, armature spindle, 5, fan, 6, air inlet, 7, guard shield, 8, air outlet, 9, ventilation slot.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1, Fig. 2, Fig. 3, shown in Figure 4 in, protecgulum 2 is installed on the stator casing 1, bonnet 3 is installed on the stator casing 1, armature spindle 4 is installed on protecgulum 2 and the bonnet 3, fan 5 is fixed on armature spindle 4 and stretches out on the rear end of bonnet 3, air inlet 6 on bonnet 3, guard shield 7 is fixed on stator casing 1 rear end, air outlet 8 is shaped on ventilation slot 9 on the inner surface of stator casing 1 on the side face of protecgulum 2.Owing to be shaped on ventilation slot 9 on the inner surface of stator casing 1, wind is entering also ventilation slot 9 from air inlet 6 and is flowing, and flows out from air outlet 8 at last, immediately heat is taken away, and the motor rapid heat dissipation, the work temperature rise is low, long service life.
