Abstract:
 In order to describe the dynamic characteristics of single-phase flux switching motor( flux switching
motor,FSM) quickly and effectively,a method of establishing the nonlinear inductance model of the
motor was presented. The mathematical expression of the air gap magnetic permeability between one pair
of stator and rotor poles was deduced by the magnetic circuit analysis method,and the variable of the expression
is the rotor position. On the basis of the air gap magnetic permeability expression and the singlephase
FSM’s working principle,the nonlinear inductance model of the motor was established; whose variable
is also the rotor position. The comparisons of back EMF waveform between prototype testing and
model computation show that the method suggested can be applied to establish the nonlinear inductance
model of single-phase FSM. The model is very accurate while the current is small. The leakage magnetic
field becomes obvious as the current increases. The leakage magnetic field is the cause of the deviation
between experimental and calculated values on the rising and falling edge of the back EMF waveform. Because
of the working principle of the single-phase FSM,the deviation doesn’t impair the accuracy of the
dynamic analysis.
