Description
Technical field
The invention relates to a kind of motor structure, be meant especially and will commonly use integral type rotor sheet of the whole circle of motor a slice and rotor fragment, the stator slice that stator piece is divided into sliceable combination again.The present invention can dwindle the size of the mfg. moulding die of each rotor fragment, stator slice significantly, not only reduce the cost of die cost, punch press machine significantly, and save the waste material that processing procedure produces significantly, even can utilize remaining material of other processing procedure or leftover bits and pieces to manufacture a product, therefore have great cost interests.
Background technology
Rotor is at the brushless motor of outer ring, be called the outward rotation type motor again, be common in application scenarios such as the hub-type motor of electric motor car and motor's for washing machine, wherein the multipolar system coil is to be combined on the stator of inner ring, each polar curve circle is to wind the line separately to become stator, stator does not rotate, and when coil is subjected to electric current, just becomes motor; If coil is produced voltage by the externally-applied magnetic field cutting, just become generator.Rotor is bigger at the race diameter of the motor of outer ring rotation, and the inboard of rotor respectively is provided with a permanent magnet with respect to the position of each utmost point of coil, and each permanent magnet generally forms the arc sheet, and inlays the inboard that is combined in rotor.Permanent magnet is embedded in the rotor inboard many methods, how can be with minimum cost, make correct location of permanent magnet and very firm rotor inboard, the key factor that must consider when being this type of electric motor structure of design of being combined in.
Known outer-rotor structure has many kinds of manufactures, common has two kinds, a kind ofly be with metal lump circle car system or be cast as columnar external rotor, its inner ring has been made many 1 road grooves with the broaching tool processing mode, each groove is used for inlaying a slice permanent magnet, since relatively more difficult with the groove shapes that broaching tool processing can be inlayed automatically, therefore often use viscose that permanent magnet is sticked on the external rotor madial wall, the mortality that so not only cost height, and increase binds; What permanent magnet reclined again is metal material, if monoblock, its magnetic conductivity is relatively poor.Though well whether the magnetic conductivity of rotor little to the performance impact of motor, still has influence by a small margin.Another kind is the rotor sheet that strikes out a whole circle with the steel disc of sheet, this steel disc can be with the very good silicon steel sheet of magnetic conductivity, so can improve the magnetic field path, then many rotor sheets are assembled into a rotor, rotor presses fit among the shell again, because shape with the steel disc punching press of sheet, can be easy to produce the groove of Any shape, therefore can be easy to be processed to form the shape that is fit to inlay the sheet permanent magnet, and form extraordinary magnetic conduction environment again, can make the field circuit of stator coil better.But want the larger-size external rotor of stamped with the steel disc of sheet, must use the large mold of higher cost, big steel disc material and large-tonnage punch press, and producing many relatively steel disc waste materials, this point makes that its manufacturing cost is high, is unfavorable for reducing the total cost of motor.
Because more than, make that commonly using the motor outer-rotor structure still exists many shortcomings, therefore improved necessity obviously arranged.In view of this inventor is actively to seek the road improved, and design, experiment via have many times caused generation of the present invention.
