Corresponding with above-mentioned rotor structure, armature disc assembly 42 comprise non magnetic material armature disc 421, be opened in the equally distributed a plurality of openings of the circumference along two different radius size on the armature disc 421, the coil 424,425 that is arranged in the iron core 422,423 of opening and is wound in iron core 422 two ends, be wound in the coil 426,427 at iron core 423 two ends, coil 424,426 is corresponding with the discshaped body 31 of a rotor, coil 425,427 is corresponding with the discshaped body 31 of another rotor, and these coils are the armature coil of armature disc assembly 42; Obviously, armature disc 421 upper sheds of armature disc assembly 42 are corresponding with discshaped body 31 upper sheds of rotor, the equally distributed a plurality of openings of the circumference along two different radius size on the armature disc 421 of armature disc assembly 42 are divided into two opening groups, are two covering of the fan sections in the same covering of the fan that launches radially from the center of circle of armature disc 421 along the opening 429 in the first opening group of the first less relatively circle distribution of radius size with along the opening 428 in the second opening group of the second relatively large circle distribution of radius size; Opening 429 in the first opening group of armature disc assembly 42 is identical along discshaped body circumferentially extending length along the opening 319 in the first opening group on the discshaped body 31 of armature disc circumferentially extending length and rotor, and it is identical along discshaped body circumferentially extending length that the opening 428 in the second opening group of armature disc assembly 42 will be grown on the discshaped body 31 with rotor the opening 318 in the second opening group along armature disc circumferentially extending length.
Actual, the armature disc 421 of armature disc assembly 42 and the matching relationship of the discshaped body 311 on the rotor 31, as shown in Figure 3, as seen, opening shape and opening form distribution rings and are complementary, and the number of same aperture distribution ring split shed is 6 times of number of the discshaped body 311 same aperture distribution ring split sheds on the rotor 31 on the armature disc 421 of armature disc assembly 42, and the width of a magnetic pole is to there being the width of three armature disc 421 upper sheds.
As shown in Figure 1, the first compound dish assembly 41 is identical with second compound dish assembly 43 structures, be symmetrically distributed, include a disk body, a plurality of groove shape coil braces, a plurality of magnet exciting coils and an armature coil, with the second compound dish assembly 43 is example, each groove shape coil brace comprises groove waist 431, the first groove pin 433, the second groove pin 434 and be wound in coil on the groove pin, disk body is non-magnetic conductive material, groove shape coil brace is strong magnetic material, as seen from the figure, disk body herein is actual to be exactly the second end 22, need to prove: the groove waist of each groove shape coil brace can separate, also can be by being to cooperatively interact by a non-magnetic conductive material to connect into a whole dish; The groove waist 431 of groove shape coil brace is fixed on the second end 22, and each groove shape coil brace is evenly distributed on the second end 22 along circumference; Number of openings in each group opening on the quantity of groove shape coil brace and the armature disc 421 is consistent, and the groove leg number that each groove shape coil brace is comprised is then consistent with the number of opening group on the armature disc 421; The groove leg that groove shape coil brace is comprised is corresponding one by one with the opening on the armature disc, and corresponding groove leg is identical with the cross sectional shape of opening; This is wound in the armature coil that coil on the groove pin is the second compound dish assembly, each is along the second groove pin 434 of the first less relatively circle distribution of radius size and go up coil 436 and constitute internal gears, and each is along the first groove pin 433 of the second relatively large circle distribution of radius size and go up coil 435 and constitute outer tooth rings; 432 of magnet exciting coils are wound between internal gear and the outer tooth ring.Obviously,, can produce the closed magnetic circuit shown in arrow among Fig. 1 with the energising of the magnet exciting coil in the first compound dish assembly 41 and the second compound dish assembly 43, this magnetic structure, the path is simple, and magnetic loss is less, can guarantee the efficient operation of motor.
Though, in the above embodiments, what be provided with on the discshaped body 31 is along the equally distributed two groups of magnetic poles of the circumference of two different radius size, similarly, armature disc 421 is provided with is along the equally distributed two groups of iron cores of the circumference of two different radius size and is wrapped in armature coil on the iron core, on discshaped body 31, be provided with along the equally distributed three groups of magnetic poles of the circumference of three different radii sizes, it also is feasible being provided with along equally distributed three groups of iron cores of the circumference of three different radii sizes and the armature coil that is wrapped on the iron core on the armature disc 421, just the closed magnetic circuit that at this moment forms will be not the square shape shown in Fig. 1, and become font on the one, further, on discshaped body 31, be provided with along the equally distributed four groups of magnetic poles of the circumference of four different radii sizes, it also is feasible being provided with along equally distributed four groups of iron cores of the circumference of four different radii sizes and the armature coil that is wrapped on the iron core on the armature disc 421, and a kind of situation that can imagine is that at this moment closed magnetic circuit will become two square shapes by the square shape shown in Fig. 1.
Certainly, increase corresponding to magnetic pole set number on the discshaped body 31, armature disc 421 upper cores and the armature coil number that is wrapped on the iron core increase equally, at this moment can require the structure of groove shape coil brace to do corresponding variation, such as: for the magnetic pole set number three situation, groove shape coil brace will be at a groove waist three groove pin to be set, in other words, at this moment groove shape coil brace will be the E font, and be four situation for the magnetic pole set number, a kind of groove shape coil brace structure that can imagine will be to be showed in groove shape coil brace among Fig. 1 along the disk body arranged radially by two separation.
Though, in the above embodiments, the number of magnet poles that each magnetic pole set comprised on the discshaped body 31 is 8, and the opening that each opening group of armature disc 421 is comprised, be interspersed in the iron core of opening and the armature coil number that is wrapped on the iron core is 48, wherein, each magnetic pole opening correspondence be the opening that each opening groups of three armature discs 421 is comprised, can infer to be that the opening that each opening group of each magnetic pole opening corresponding four or more armature disc 421 is comprised also is fine.And for the person of ordinary skill of the art, the number of magnet poles that each magnetic pole set comprised is abideed by electric machine theory, as long as more than or equal to two.
Though in the above embodiments, the number of the discshaped body 31 that rotor comprised is two, actual this number also can be one, can also be three or greater than three.Obviously, for the situation of having only a discshaped body 31, above-mentioned armature disc assembly 42 is unwanted, and for having three or greater than the situation of three discshaped body 31, above-mentioned armature disc assembly 42 will be arranged in twos between the discshaped body 31.As seen, the number of armature disc assembly 42 number that remains the discshaped body 31 that comprises than rotor lacks one.
Foregoing; it only is preferred embodiment of the present invention; be not to be used to limit embodiment of the present invention; those of ordinary skills are according to main design of the present invention and spirit; can carry out corresponding flexible or modification very easily, so protection scope of the present invention should be as the criterion with the desired protection range of claims.
