【摘要】 爪极电机已被愈来愈广泛的应用于航天、汽车等国民经济的各个领域。因而，对其参数和性能的精确分析已愈显重要。本文根据三维有限元的基本原理，通过电磁场数值计算软件包ANSYS，对爪极电机的空载时的磁场进行了计算，并在此基础上，利用能量摄动法进一步研究和计算了空载时电机各个绕组的自感和互感，从而得出了空载时的相电压波形。并计算了在爪极间加入磁钢后爪极电机的磁场分布和电感参数。更多还原

【Abstract】 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.更多还原
