Specific implementation mode
With reference to attached drawing, the present invention includes stator poles iron core 1, stator poles coil 2, rotor pole 3, shaft 4, and stator poles iron core is
By the groove type iron core for the integral structure that crossbeam is constituted with the salient pole for being symmetrically connected to crossbeam both ends, the axial end face top of salient pole
It is isosceles trapezoid for rectangle, lower part, and the arc surface that the lower face of salient pole is indent, the axis projection position of the lower face of salient pole
It is projected as on the circle in the center of circle in rotating shaft core, stator poles iron core is formed by permeability magnetic material silicon steel plate stacking, and stator poles coil twines
It is wound on stator poles iron core crossbeam, stator poles iron core and stator poles coil constitute stator poles；The axial end face of rotor pole is in sector
Face, end face is the arc surface of evagination, the arc surface that lower face is indent thereon, rotor pole by permeability magnetic material silicon steel plate stacking and
At rotor pole is fixed by connector 5 with shaft, and connector is made by non-magnet material, the upper surface and lower face of rotor pole
Axis projection be located at two that the center of circle is projected as with rotating shaft coreConcentric circlesOn, rotor pole can rotate to fixed with shaft
In the groove of sub- pole iron core, and in the groove of stator poles iron core, upper surface and the stator poles winding space of rotor pole coordinate, turn
The two sides of sub- pole and the salient pole clearance fit at stator poles iron core both ends, the axis projection of rotor pole lower face and stator poles both sides
