On, rotor is permanent magnet.Its armature winding is polyphase windings, and generally three-phase, DC brushless motor is used primarily in electricity at present
Dynamic bicycle and electric car industry are relatively more, and advantage is that power density small in size is big, compared with three phase alternating current motor, when low speed
Biggish torque can be exported, the quantity ratio generally 3:2 of winding slot and magnetic pole, the smallest there are three slot the two poles of the earth, and there are commonly ten
Two slot octupoles etc..The disadvantage is that inefficient, average service efficiency 70% or so, main cause is the side effect band of counter electromotive force
Come magnetic resistance, have certain braking action when rotated to rotor, thus affect the overall output efficiency of motor.
Summary of the invention

Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples:
Fig. 1 is structural schematic diagram of the invention；
Stator and rotor condition partial schematic diagram when Fig. 2 is present invention commutation.
Specific embodiment
As shown in Figure 1, the present invention provides efficient direct current permanent magnetic brushless, including stator 1 and rotor 2, the stator 1 is wrapped
Containing the one group of A phase winding and B phase winding being circumferentially interspersed, the slot number of stator winding and the ratio of rotor magnetic pole number are 4:6.
Preferably, the initial start angle of the rotor is 10o~15o.
When starting, the pole N and the magnetic pole of the pole S two of a stator winding magnetic pole while respective rotor are mutually exclusive with the same sex
It pushes forward, there is a natural attraction between the sexes traction, while there is motive force and tractive force, will push when A phase winding magnetic pole is the pole N corresponding
The pole N of rotor, when the pole N of rotor by stator N extremely it is mutually exclusive push forward while, the pole N of the winding of stator and the S of rotor
Pole, which is that there is a natural attraction between the sexes, operates rotor continuation forward；As shown in connection with fig. 2, when the rotor is turning, by Hall control when stator is left in the pole N
Device processed commutates rapidly, and at this time the magnetic pole of stator is that the pole N of rotor is drawn in the pole S of the pole S drive rotor simultaneously；B phase winding and A phase
The working principle of winding is identical, and this will not be repeated here；It repeats the above process, motor runs well.
The slot number of stator winding and the ratio of rotor magnetic pole number are 4:6, and the slot number of the present embodiment stator winding is 8, turns
Sub- number of magnetic poles be 12,6000 revs/min of Rated motor revolving speed, with 12 slot octupole rated speed of conventional DC brushless motor
3200 revs/min compare, and in the case where same power similarly inputs energy consumption with size, revolving speed is higher by by about one time.
Stator field and the rotor field drive rotor in such a way that identical charges repel each other operate when starting, using this Starting mode
Can effectively reduce stator winding when being powered power-off generated counter electromotive force to the magnetic brake power of rotor, thus reduce rotor with
