121 width ratio can be 1：1.05, i.e. the width of rotor tooth 121 is more than the width of the first stator tooth 131, and rotor tooth 121
Width be less than the first stator slot 134 width.Correspondingly, the width of the second stator tooth 132 and the width ratio of rotor tooth 121 are
1:1.05-0.95, the width of third stator tooth are 1 with the width ratio of rotor tooth 121:1.05-0.95.
The present embodiment is 1 by the width ratio of width and stator tooth that stator slot is arranged:0.95-0.85, the width of stator tooth
The width ratio of degree and rotor tooth is 1:1.05-0.95 enables to the inductance curve of switched reluctance machines with the position of rotor tooth
Set in triangular waveform change, as shown in figure 9, and inductance curve change rate it is big.
Wherein, the air gap between rotor 12 and stator 11 can be 0.1mm~3mm, width and the rotor tooth 121 of stator slot
The difference of width is 8-12 times of air gap, and the wherein width of stator slot is the width of rebate of stator slot, and the width of rotor tooth 121 is
The width at 121 top of rotor tooth.That is the difference of the width of the width and rotor tooth 121 of the first stator slot 134 is the 8-12 of air gap
