An Investigation On Magnetic Fields And Inductance Calculation Of Claw-pole Alternator

Claw-pole alternator has been more and more widely used in many fields in national economy ,such as aviation, automobile,etc..Therefore,an accurate analysis on its parameter and characterise is very important.The magnetic field under no-load was calculated by three dimentional finite element method.On this basis,an investigation on the self and mutual inductance calculation of phase windings by energy perturbation methods had been made and the phase voltage under no-load was obtained.The magnetic field and inductance of a permanent alternator was also calculated in this thesis.
