The useful flux area of magnetic pole magnet steel.Certainly, in other embodiments of the invention, the second permanent-magnet pole 12 can also be set to
V-arrangement is W-shaped, as long as other modes of texturing under design of the invention, within the scope of the present invention.
When actual design, the coercive of the first high-coercive force magnet steel 113 and the second high-coercive force magnet steel 121 in the present embodiment
Power may be the same or different.When the first high-coercive force magnet steel 113 and 121 coercivity difference of the second high-coercive force magnet steel,
The coercivity of second high-coercive force magnet steel 121 is higher than the coercivity of the first high-coercive force magnet steel 113, but coercivity difference is 20%
Within.
Similarly, the coercivity of the first low-coercivity magnet steel 111 in the present embodiment and the second low-coercivity magnet steel 112 can
With identical, can also be different.When the coercivity difference of the first low-coercivity magnet steel 111 and the second low-coercivity magnet steel 112, first
The coercivity difference of low-coercivity magnet steel 111 and the second low-coercivity magnet steel 112 can effectively promote magnet steel 3 within 20%
Anti- demagnetization capability.
For the first high-coercive force magnet steel 113 and the second high-coercive force magnet steel 121, in the present embodiment first
Low-coercivity magnet steel 111 and the second low-coercivity magnet steel 112 are relatively low.Such as it is the first low-coercivity magnet steel 111 and second is low
The coercivity of coercivity magnet steel 112 is set as 100A/m or so, then corresponding first high-coercive force magnet steel 113 and the second high coercive
The coercivity of power magnet steel 121 is 1000A/m or so, practical to be designed according to the specific requirements of motor.
Motor in the present embodiment can apply sufficiently large electric current and change the second low-coercivity during being demagnetized
The magnetism of magnet steel 112 reaches reversed, the anti-demagnetization capability promotion of the first low-coercivity magnet steel 111, during becoming magnetic flux
Second low-coercivity magnet steel 112 is not influenced by demagnetization current, and remanent magnetism is constant；Therefore only second low during entire adjustable magnetic
Coercivity magnet steel 112 plays adjustable magnetic, the variation of 112 magnetic direction of the second low-coercivity magnet steel；And the first low-coercivity magnet steel 111
Due to 113 series arrangement of the first high-coercive force magnet steel, the first high-coercive force magnet steel 113 has the first low-coercivity magnet steel 111
Magnetic assist effect externally shows that coercivity is promoted, therefore adjustable magnetic process magnetism is constant, does not play the role of adjustable magnetic in whole process,
And then has the function that improve the adjustable magnetic range of motor, promotes motor adjustable magnetic multiple.
Referring again to shown in Fig. 1 and Fig. 2, in the first permanent-magnet pole 11, the first low-coercivity magnet steel 111 and the second low coercive
Power magnet steel 112 is H in rotor dislocation distance radially, the second low-coercivity magnet steel 112 in rotor radially
Width is H2, and the first low-coercivity magnet steel 111 is H3 in the width of rotor radially, and the first high-coercive force magnet steel 113 exists
The width of rotor radially is H4, and the second high-coercive force magnet steel 121 is H1 in the width of rotor radially, wherein-
