Length.
A certain number of aluminium fan blade is evenly equipped with the outer face of aluminium end ring described in the utility model.
A certain number of balance aluminum post is evenly equipped with the outer face of aluminium end ring described in the utility model.
It is of the present utility model to have the technical effect that：1st, the strong copper sliver of electric conductivity is employed, the efficiency of motor is greatly improved
Level；2nd, outer aluminium sliver, interior aluminium sliver, aluminium end ring are integral, and are manufactured using aluminum process, and inverted trapezoidal copper sliver is served
Good fixation, while inverted trapezoidal copper sliver two ends are provided with after Baltimore groove, the full aluminium of Baltimore groove casting, further fixes inverted trapezoidal
Copper sliver, so prevents copper bar play, while copper bar is not required to weld again, can prevent copper bar sealing-off；3rd, the utility model inverted trapezoidal
Copper sliver length is equal to rotor core length, is not required to as inserting copper bar construction rotor, copper sliver is longer than rotor core, so section
End copper is saved；4th, outer aluminium sliver, interior aluminium sliver, aluminium end ring, aluminium fan blade and balance aluminum post are integral, using aluminum process
Manufacture, aluminum process is simpler than cast copper, and cost is low；5th, the outer aluminium improved in the stall performance of motor, rotor core is led
Bar is equivalent to the upper cage sliver of double-cage rotor, and the inverted trapezoidal copper sliver in rotor core leads equivalent to the lower cage of double-cage rotor
Bar.Upper cage sliver is aluminium and sectional area is small, and resistivity is high, and resistance is big, motor is had excellent stall performance, can adjust outer aluminium
Sliver is wide and height, adjusts area, using kelvin effect, is optimal the stall performance of rotor；Lower cage sliver is copper and section
Product is big, and resistivity is low, and resistance is small, and low, electric efficiency height during operation is lost；6th, outer aluminium sliver is up-narrow and down-wide to be trapezoidal, it is upper it is narrow can
Kelvin effect is utilized well, is optimal the stall performance of rotor, lower width is then added contacts conductive area with copper sliver.
And trapezoidal fixation is difficult to loosen；7th, the bracket groove of rotor punching is inverted trapezoidal through hole, wide at the top and narrow at the bottom, makes the rotor facewidth more reasonable,
And then tooth magnetic it is close more rationally, improve motor performance, copper sliver be inverted trapezoidal, upper width add with rotor punching contact area, make
Copper sliver can bear bigger centrifugal force.Inverted trapezoidal copper sliver, simple shape is easy to process, and market is common；8th, interior aluminium sliver is
Inverted trapezoidal, wide at the top and narrow at the bottom, upper width is then added contacts conductive area with copper sliver.And trapezoidal fixation is difficult to loosen；9th, rotor
Provided with aluminium fan blade, can preferably it radiate；10th, rotor is provided with balance aluminum post, can use weighting procedure or the rotor balancing of duplicate removal method school.Plus
During weight method school rotor balancing, added equalizing wahser riveting jail is on balance aluminum post；During the rotor balancing of duplicate removal method school, it can remove corresponding
Balance aluminum post.
