Background technology
With the continuous deterioration of natural environment, and fossil energy is in short supply, and electric automobile is being reduced to fossil
While fuel dependence and environmental pollution, it is ensured that the mankind move flexibility and realize effective road of automobile industry sustainable development
Footpath.Electric energy is as a kind of new cleaning fuel, the inexorable trend that will develop as future source of energy, and electric automobile also will necessarily substitute
Traditional fuel-engined vehicle turns into the dominant force of New Times.Electric automobile includes pure electric automobile, fuel cell electric vehicle and mixing
Power electric automobile.Mixed power electric car is the efficient combination of conventional internal combustion rolling stock and electric vehicle, and it inherits electricity
The advantages of electrical automobile low emission, the petroleum fuel strong point higher than energy and specific power has been developed again, has significantly improved conventional internal combustion
The discharge of machine automobile and fuel economy, add the continual mileage of electric automobile.
Hybrid power vapour based on integrated starter/generator (Integrated Starter/Generator, ISG)
Car, ISG is directly installed on internal combustion engine crankshaft output, flywheel and original starter and generator is instead of, as vapour
The auxiliary power source of car.When the characteristics of automatic start stop system is quick started using motor avoids internal combustion engine low speed and starts and be long
Between idling, improve vehicle fuel consumption and emission performance.
But the existing magneto applied to ISG is being designed and there are problems that in practical application, such as motor flux leakage
It is logical big, power factor is low, counter electromotive force sine is poor, efficiency is low, vibration noise is big.
The content of the invention
The purpose of this utility model is to provide a kind of ISG motors built-in permanent magnet motor rotor lamination structure, passes through magnetic
The mode of road optimization, reduces leakage magnetic flux, improves ISG motors in the operating power factor that works, the sine of counter electromotive force, effect
Rate and vibration noise.
The technical scheme that the utility model uses to achieve the above object is：A kind of ISG motors interior permanent magnet machines
Rotor punching structure, include the main part of annular, caved inward on main part outer circumference wall provided with multiple circular arcs
Interpolar magnet isolation tank, interpolar magnet isolation tank are evenly spaced on main part outer circumference wall, between every two neighboring interpolar magnet isolation tank
Spacing is equal, is provided with a permanent magnet trough for being used to assemble permanent magnet between every two neighboring interpolar magnet isolation tank on main part,
Each permanent magnet trough mutually caves inward provided with magnetic-leakage preventing groove close to the madial wall of end positions.
It is of the present utility model further technical scheme be：The interpolar magnet isolation tank semicircular in shape.
It is of the present utility model further technical scheme be：The magnetic-leakage preventing groove semicircular in shape.
The utility model ISG motors are had the advantages that with built-in permanent magnet motor rotor lamination structure：1. turning
Multiple permanent magnet troughs of angle at equal intervals are formed in sub- punching, simplify the insertion technique of permanent magnet；2. in the cylindrical of rotor punching
Zhou Shang, the center of arbitrary neighborhood two-poled permanent magnets set interpolar magnet isolation tank, improve the sine of counter electromotive force of motor waveform,
Reduced harmonic component, smaller iron loss unshakable in one's determination, improve operational efficiency；3. in permanent magnet trough close to end positions（Permanent magnet point
Portion）Provided with magnetic-leakage preventing groove, weaken the leakage magnetic flux of each magnetic pole, strengthen motor main flux, improve the power in motor operation course
Factor.
The utility model ISG motors are made with built-in permanent magnet motor rotor lamination structure with reference to the accompanying drawings and examples
Further instruction.
