Embodiment

This DC motor is made up of stators and rotators, as shown in Figures 1 and 3, stator comprises main pole 1, brush 2, bearing, support, support is the shell of DC motor, the combination of loading ability of bearing rotor and stator and motor power export, stator main pole 1 is two permanent magnets with parallel surface, and parallel being fixed on support forms main field, and two magnetic pole strengths are respectively N pole and S pole; Rotor is made up of rotating shaft 3, rotor core 4, commutator 5, rotor coil 6, and rotating shaft 3 is connected with bearing with the center of rotor core through commutator successively.

Commutator 5 as shown in Figure 2, is cylindrical structural, comprises two conduction regions and two insulation layers, conduction region is connected with rotor coil, conduction region or insulation layer central angle are 85-95 degree, are preferably 90 degree, and it is 180 degree that conduction region adds an adjacent with it insulation layer angle; A point is to B point, C point to D point facing conductive, and B point is to C point, D point to A point opposing insulation; Rotor core 4 is magnetic conductor, be formed by stacking by iron block or stalloy, can be structure as a whole, also can be non-integral structure, the arc body that the radial direction comprising intermediate bar and bar two ends is arranged, can be semicircular body or semiellipsoid or other arc body, semicircular body can be more than half circle or smaller part circle, and semiellipsoid can be large semiellipsoid or little semiellipsoid; Its two ends weight ratio is broad in the middle, rotor coil 6 is wrapped on rotor core 4, rotor coil 6 is connected with rotor commutator 5 conduction region, commutator 5 conduction region contacts with stationary brushes 2 to rotor coil 6 electric current, commutator changes the sense of current of rotor coil simultaneously, has the rotor coil 6 of electric current to make rotor core 4 become rotor electromagnetic pole.

As shown in Figure 1, the rotor core 4 being wound with rotor coil 6, be placed in the main field of stator main pole 1 formation, rotor core 4 two ends are by the attraction of main field, rotor core 4 two ends central point turns to main magnet closest to position, at this moment DC power supply passes through brush 2 with rotor commutator 5 conduction region to rotor coil 6 direct current, the electromagnetic pole that rotor core 4 is formed by rotor coil 6 magnetization and stator main pole l repel mutually, rotor rotates about 90 degree by repulsive force, now commutator 5 forwards the commutator insulation district contacted with brush 2 to, rotor core 4 is by the attraction of main pole 1, rotor starts rotation, again rotate about 90 degree, now commutator 5 forwards again the commutator conduction region contacted with brush 2 to, the electromagnetic pole that rotor core 4 is formed by rotor coil 6 magnetization and stator main pole 1 are repelled mutually, rotor rotates 90 degree again, now commutator 5 forwards the commutator insulation district contacted with brush 2 to, rotor core 4 is by the attraction of main pole l, rotor is rotation again, rotate about 90 degree, complete the rotation of a week.This DC motor utilizes rotor core 4 by the attraction of main pole 1, and rotor magnetic pole is by the repulsive force of main pole 1, and mutual circulation, the impact by inertia makes rotor direction be consistent.

As shown in Figure 1, DC motor provided by the invention, adopt the permanent magnet in two parallel poles faces, and rotor core 4 two ends are set to semicircular body or semiellipsoid, make rotor core 4 be subject to the starting point of main pole 1 attraction from the main field center magnetic line of force farthest, terminal is nearest from the main field center magnetic line of force; Rotor magnetic pole is nearest from the main field center magnetic line of force by the starting point of main pole 1 repulsive force, and terminal from the magnetic field center magnetic line of force farthest.
