Description
Technical field
The utility model relates to a kind of brushless electric machine, especially wind cooling refrigerator brushless electric machine.
Background technology
Existing brushless electric machine, motor body is placed in end cap, because it is in wind cooling refrigerator, easily makes moist and liquid is stretched in motor thus causes the damage of motor, and does not have special safeguard procedures, easily by external force deformation due to end cap.
Utility model content
In order to overcome the easily impaired deficiency of existing brushless electric machine, the utility model provides wind cooling refrigerator brushless electric machine.
The utility model solves the technical scheme that its technical problem adopts: wind cooling refrigerator brushless electric machine, comprise motor, rotor, stator, end cap, field effect transistor and circuit board, motor outer wrapping is in end cap, rotor and stator is provided with in motor, field effect transistor and circuit board are fixed in end cap, inside end cap, surrounding is provided with sealing ring, is provided with bubble barrier film between end cap and motor.
According to another embodiment of the present utility model, comprise further on bubble barrier film and be also provided with the withstand voltage layer of silica gel of one deck.
According to another embodiment of the present utility model, comprise end cap further and be provided with nano-sized hydrophobic layer.
The beneficial effects of the utility model are, this brushless electric machine can prevent liquid from infiltrating motor, and can provide certain surge guard for motor, has saved cost, has improve effect.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
1. motors, 2. rotor, 3. stator, 4. end cap, 5. field effect transistor, 6. circuit board, 7. sealing ring in figure, 8. bubble barrier film, 9. withstand voltage layer of silica gel, 10. nano-sized hydrophobic layer.
Embodiment
If Fig. 1 is structural representation of the present utility model, wind cooling refrigerator brushless electric machine, comprise motor 1, rotor 2, stator 3, end cap 4, field effect transistor 5 and circuit board 6, motor 1 outer wrapping, in end cap 4, is provided with rotor 2 and stator 3 in motor 1, field effect transistor 5 and circuit board 6 are fixed in end cap 4, inside end cap 4, surrounding is provided with sealing ring 7, be provided with bubble barrier film 8 between end cap 4 and motor 1, bubble barrier film 8 is also provided with the withstand voltage layer of silica gel 9 of one deck, end cap 4 is provided with nano-sized hydrophobic layer 10.
The sealing ring 7 of end cap 4 surrounding can make between end cap 4 and motor 1 seamless airtight, thus prevent liquid from infiltrating, and bubble barrier film can to make between motor 1 and end cap 4 from a distance, cool exterior air directly can not be conducted to motor 1 from end cap 4, certain anti-pressure ability can also be provided, withstand voltage layer of silica gel 9 then can better play shock proof effect, nano-sized hydrophobic layer 10 on end cap 4 can make liquid cannot rest on end cap 4, decrease the risk be corroded, this brushless electric machine can prevent liquid from infiltrating motor, and certain surge guard can be provided for motor, save cost, improve effect.
