Description
Technical field
The utility model relates to motor design manufacturing technology field, especially relates to a kind of stator punching of plastic packaging motor of optimal design.
Background technology
The operation principle of AC induction motor is in stator winding, to feed alternating current, make stator core produce rotating magnetic field, and the rotor cutting magnetic line produces induced current and rotating magnetic field interacts, and AC induction motor is rotated.The stator of AC induction motor is generally punching and forms with coiling.The stator punching of traditional alternating current asynchronous plastic packaging motor that is used for air-conditioning fan is generally the middle part and is provided with circular hole, is evenly distributed with the some punching grooves that are provided with along the radial direction of stator punching between cylindrical and the circular hole, and the exradius of stator punching is generally 74～78mm; The radius of circular hole is generally 42mm, and the facewidth is all identical, is 3mm; Through the magnetic circuit computational analysis, this stator laminating structure exists not enough: one, the characteristic of monophase machine has determined that monophase machine magnetic field is oval; Adopt impartial stator tooth; Then the close distributional difference of the magnetic of tooth portion is bigger, and the ferromagnetic material utilance is low, has also caused electric efficiency decline; Two, this stator punching is used on the AC asynchronous motor of air-conditioning fan usually the stator teeth magnetic flux density and is about 14000 and yoke portion magnetic flux density is about 12000; And the magnetic flux distribution of phase raker tooth portion under different cycles of tooth portion is uneven; Obviously exist tooth portion and the magnetic flux density collocation of yoke portion unreasonable, influence electric efficiency and electromagnetic noise; Three, the punching groove area of stator punching is bigger, and the utilance of punching groove area because the punching groove fails to make full use of, causes electric machine temperature rise and magnetic leakage factor to increase about 55%, has reduced electric efficiency; Four, reduced the useful life of motor.
The utility model content
In order to solve the deficiency that exists in the above-mentioned prior art, the utility model has designed a kind of motor magnetic flux distribution of improving, and improves the stator punching of the plastic packaging motor of electric efficiency.
