Embodiment 1
See Fig. 1, the heterogeneous electric excitation synchronous motor of one of the present utility model, comprise stator 11 and rotor 10, stator 11 and rotor 10 are all permeability magnetic material and have air gap therebetween, stator 11 is provided with magnetic teeth 110, magnetic teeth 110 is arranged alternately concentrated armature winding 111 and central excitation winding 112.In the present embodiment motor, m=3, k=1, n=2, wherein, m is the number of phases of motor, n and k is positive integer, and n is electric motor units number, and k is concentrated armature winding 111 logarithm of a phase armature winding series connection in each electric motor units.That is, this motor is three phase electric machine, has A, B, C three-phase, includes 2 electric motor units, has k=1 to concentrated armature winding in each electric motor units.So the number of stator 11 magnetic teeth 110 is Ns=4*m*k*n=24, the number that magnetic teeth 110 is provided with concentrated armature winding 111 is successively 2*m*k*n=12, each concentrated armature winding 111 overlaps two magnetic teeth 110, and adjacent concentrated armature winding 111 shares a groove; 2*m*k*n=12 central excitation winding 112 is set gradually in all the other 2*m*k*n=12 groove, each central excitation winding 112 overlaps two adjacent magnetic teeth 110, every two central excitation windings 112 share a groove, and the magnetic direction that adjacent two central excitation windings 112 produce is contrary; Excitation winding coupled in series in stator 11 in first electric motor units forms the first excitation winding unit, and the first excitation winding unit and the second excitation winding unit can serial or parallel connection composition excitation winding.Rotor 10 is made up of teeth groove type permeability magnetic material, and rotor magnetic teeth and stator magnetic teeth 110 are oppositely arranged, and the number of rotor magnetic teeth is Nr=(2*m*k ± 1) n, and work as k=1, when m=3, n=2, Nr can be 10,14, and the present embodiment gets Nr=14.
Due to k=1 in the present embodiment, n=2, in each electric motor units, any phase armature winding is composed in series (A3 and A4 as in A1 and A2 in the first electric motor units in Fig. 1 or the second electric motor units) concentrated armature winding 111 by k=1, from first concentrated armature winding of any phase (as from A1), the concentrated armature winding of k=1 placed adjacent is had to belong to same phase (only having A), thereafter B1 and C1 in k=1 concentrated armature winding 111(and Fig. 1 belonging to adjacent phase is set gradually), according to above-mentioned arrangement mode, in three-phase set in first electric motor units, the arrangement mode of armature winding is: A1-B1-C1-A2-B2-C2.2k=2 the concentrated armature winding 111 belonging to homophase forms k=1 to armature winding in complementary sets (A1 and A2 namely in Fig. 1), wherein concentrates for any pair in armature winding 111 two to concentrate armature winding to differ half rotor polar distance τ with secondary relative position
s, correspond to 180 degree of electric angles, the two has complementary characteristic, and when being composed in series a phase winding, the back-emf harmonic wave in complementary concentrated armature winding is cancelled out each other, and phase electromotive force is more sinusoidal.As in the first electric motor units, armature winding A1 is concentrated to stride across two magnetic teeth, its center line faces the center line of rotor 10 tooth, and concentrate the center line of armature winding A2 to face the center line of rotor 10 groove, the two differs half rotor 10 pole span with the relative position of rotor 10, spatially differs 180 degree of electric angles.The magnetic direction produced due to excitation winding is contrary, and the winding mode rationally arranging armature winding A1, A2 can make to produce back electromotive force in winding and mutually superpose.But when rotor 10 rotates in an electrical cycle 360 ° (that is, rotating rotor 10 pole span) process, there is the difference on magnetic circuit in concentrated armature winding A1 and A2 and rotor 10 relative position.As shown in Figure 1 during position, as supposition now concentrates the magnetic linkage in armature winding A1 to be approximately zero, be called the first equilbrium position, the magnetic linkage in armature winding A2 is now concentrated also to be approximately zero, because concentrated armature winding A2 is different from the position of A1 relative rotor, differ half rotor 10 pole span, therefore this position is called the second equilbrium position.Be rotated counterclockwise in an electrical cycle process at rotor 10, concentrate magnetic linkage amplitude change procedure in armature winding A1 to be:---positive maximum amplitude---the second equilbrium position---negative maximum amplitude---the first equilbrium position, the first equilbrium position;---positive maximum amplitude---the first equilbrium position---negative maximum amplitude---the second equilbrium position and magnetic linkage amplitude change procedure is in concentrated armature winding A2: the second equilbrium position.Therefore, the magnetic linkage variation tendency symmetrical complement in two parts armature winding.Concentrate in armature winding A1, A2 the magnetic linkage produced to be all bipolarity magnetic linkage (that is, have just having negative), this feature is different from traditional double-salient-pole electro-magnetic motor.Concentrate the counter potential waveform produced in armature winding A1 and A2 also to have symmetry, after being composed in series A phase winding, its harmonic component is cancelled out each other, and the opposite potential obtained has good sinuso sine protractor.
Equally, concentrated armature winding A3, A4 in the second electric motor units also have the characteristic of the first electric motor units, therefore, concentrate and also have complementary characteristic between armature winding A3, A4.When concentrated armature winding A1, A2, A3 and the A4 in two electric motor units is composed in series A phase winding, the back-emf high order harmonic component produced in concentratred winding is cancelled out each other, A phase winding back-emf fundamental voltage amplitude is approximately four times of concentratred winding A1, A2, A3 and A4 fundamental voltage amplitude, there is good sine, thus reduce torque ripple, be highly suitable for brushless ac (BLAC) and control.
B, C two-phase has the feature of A phase equally, phase place mutual deviation 120 ° of electrical degrees between three-phase.
When motor needs to operate in high speed, reduce the size of DC excitation electric current, thus reduce the excitation field intensity of motor, reach speed governing object.When needing during low speed to increase motor torque, DC excitation electric current can be increased, improve Driving Torque.
