Technical field
The present invention relates to the fields of anti-electrocorrosion more particularly to a kind of anti-electrocorrosion suitable for miniature motor, and piece is connected
Fixed structure.
Background technique
The bearing galvano-cautery phenomenon of motor is usually caused by three parts reason: first is that motor during operation three-phase without
Method absolute equilibrium, inside will generate certain alternating magnetic field, and rotor is usually by the metal materials texture such as rotor core, shaft
At rotation will generate electromotive force in magnetic field, to generate shaft voltage.Second is that air-supply fan blade is constantly cut in dry environment
Air can generate a large amount of electrostatic.Third is that some insulation rotors are internal in rotary course the electric discharge for itself forming similar capacitor
Structure.These can all cause the inside and outside load of bearing in certain potential difference, will puncture axis when inner ring runs up to enough charges
It holds oil film and generates electric discharge phenomena, galvano-cautery occurs for melting steel ball.
And prevent bearing galvano-cautery, it is clear that we can solve the problems, such as from the most fundamental bearing, for example use pottery
Porcelain ball bearing, but it is ten times of plain bearing or more that its is at high price, and in the today increasingly with keen competition that globalizes, affirmative is uncomfortable
For producing in enormous quantities.So many manufacturers use a kind of alternative solution of relative efficiency, upper and lower bearing chamber is connected with conductor
End cap realizes that end cap conducting achievees the effect that certain to prevent galvano-cautery to equilibrium potential difference.The prior art is usually adopted in the market
With following several schemes: being 1. affixed directly to motor surface with conductive tape and upper and lower end caps realize conducting.2. using conducting wire,
Or metal conduction piece is fixed by modes such as screw, pins.Such as patent document " electric motor end cap feed-through assembly and its motor "
The structure of (publication number: CN205283297U).3. metal material plastic packaging is finally realized that upper and lower end caps (have in stator interior
Structure also includes stator core) conducting, Panasonic Corporation has relevant patent protection.These above-mentioned schemes are each advantageous and scarce
It is complicated at high cost to put or connect unreliable or production technology, and full-automatic mass production all difficult to realize,
China requires above scheme today that industry 4.0 is done step-by-step that cannot clearly meet the requirements.
