Embodiment
The utility model is described further below in conjunction with the accompanying drawings.
A kind of birotor flux switch motor as shown in Figure 1, 2, including stator and rotor, the rotor include being arranged at
The left rotor and right rotor of stator both sides, the left rotor and right rotor form independent air gap with stator respectively,
The stator is made of stator axis 1, lead-out wire 7 and the permanent magnet 4 connected by stator support 6 and stator winding 5, and the left side turns
Rotor tooth 9,10 opposite, that quantity is equal is provided with son and right rotor.
Further, the N-S extreme directions of the permanent magnet 4 are parallel to 1 axis direction of stator axis, and with 1 axis of stator axis
It is uniformly distributed centered on line.
Further, as shown in Fig. 4,6, the stator winding 5 is wound in the winding slot centered on permanent magnet 4,
Its winding pole orientation is parallel with 1 axis of stator axis.
Further, the left rotor and right rotor are connected as a single entity by connecting retainer plate 8.
Further, as shown in Fig. 3,5, equal turn of quantity is respectively arranged with the left rotor and right rotor
Sub- tooth 9,10,
Further, the rotor tooth 10 of the rotor tooth 9 of the left rotor and right rotor is opposite respectively, its rotation side
To identical with rotary speed.
Further, as shown in Fig. 6,8, the rotor tooth 9,10 is the small tooth-shape structure of outer imperial palace.
Further, the connection retainer plate 8 is to be fixed with wheel hub composite construction 8-1 or the wheel hub compound with rotor
Supporting structure 8-2.
Further, position sensor is set at the left rotor and right rotor.
The course of work of the utility model is：When stator winding 11-1 formed magnetic field it is consistent with permanent magnet magnetic field direction,
Resultant field is enhanced magnetic field, promotes rotor teeth directional winding 11-1 at 9-1/10-1 to rotate, when rotor gear piece is close to stator
Tooth correspondence position, magnetic field are weaker.And current direction is reverse at this moment, resultant field further weakens.11-2 windings are powered at the same time,
Equally promoting the neighbouring rotor teeth directional of 11-2 slot for windings, its is close, promotes rotor tooth to rotate.Mode successively, in cycles, three-phase phase
Armature winding passes to alternating current in turn, promotes rotor constantly to rotate, and is then exported by shaft end lead-out wire 7.
