Inventor employs many plastic packaging DC Brushless Motor electric corrosion prevention technologies before the present invention is made, by motor
Metal cover ground wire or connect the structure of larger metallic object, during can motor be operated caused electric charge by bearing outside
Circle-metal cover-the earth bleed off falls, so as to reach electric corrosion prevention effect.But the above method is deposited needs extra connection ground when mounted
When the operation of line, installing trouble, and generally connecting ground wire using means such as wires, not only long-term reliability of its connection is difficult to
Ensure, and internal cabling can be added, influence security and aesthetic property.
The plastic packaging motor of correlation technique equally has mounting structure prominent laterally, and this mounting structure is BMC resins
Integrated injection molding, its material are BMC resins, are non-conductive material.Generally air-conditioner outdoor unit fixed installation blower motor is
One metallic support, the mounting structure part of motor is fixedly connected with metallic support using screw.Motor and mounting bracket it
Between by BMC insulation resins, potential difference will be produced between motor and air-conditioning.Therefore, the invention provides one kind to have new construction
Motor.
The present invention provides can a kind of simple and reliable plastic packaging motor galvanic corrosion solution countermeasure.The present invention proposes a kind of plastic packaging electricity
Machine, its periphery have mounting structure prominent laterally, and the mounting structure part material is conductive material.
Using the present invention, electric motor mounting structure part is conductive material, is connected between motor and air conditioner support for electric conductivity
Connect, potential difference would not be produced, caused electric charge is released by connecting metallic support in motor operating, reduces generation galvanic corrosion
Risk.
Certainly, motor of the invention can also be applied in other equipment,
Embodiments of the invention are described below in detail, the example of the embodiment is shown in the drawings, wherein from beginning to end
Same or similar label represents same or similar element or the element with same or like function.Below with reference to attached
The embodiment of figure description is exemplary, it is intended to for explaining the present invention, and is not considered as limiting the invention.
As figure, motor according to embodiments of the present invention, including plastic-sealed body, plastic packaging in the stator 1 in plastic-sealed body, positioned at plastic packaging
The end cap 14 of rotor 2, connecting stator 1 in the mesopore of body, motor periphery are provided with outstanding mounting structure 3, mounting structure 3
Conducted with the stator core 4 of stator 1, mounting structure 3 is used to install motor, can be by motor with being used for by mounting structure 3
The support conducting of motor is installed.
Motor according to embodiments of the present invention, there is mounting structure 3, motor can be installed to by mounting structure 3 and set
In standby, moreover, can be conducted equipment (such as air-conditioning etc.) with motor by mounting structure 3, so that by equipment and motor
Current potential is adjusted to same level, be effectively prevented from producing voltage difference between motor and equipment, avoids bearing 5,6 galvano-cautery
Occur, and it is simple and reliable for structure, it is adapted to produce in enormous quantities.
Wherein, mounting structure 3 can be integrally that material makes, and form mounting structure 3 using conductive material in other words,
Mounting structure 3 can be arranged to the form that a part is conductive material, such as the shape for setting metallic conductor to be combined with covered plastics layer
The form of conductive layer is set in formula, or use working of plastics, it is only necessary to can be incited somebody to action while installing motor by mounting structure 3
