摘 要：起动/助力/发电一体化系统汽车系统要求电机高效，高功率密度，低脉动转矩。Halbach电机是一种新型永磁电机。独特的永磁体结构不仅使其磁极磁场呈正弦分布，而且还可以增加气隙磁通密度，削弱转子轭部磁通密度，这使得在提高电机的功率密度的同时，又可以减小电机的体积，提高电机的效率。首先编写了Halbach电机和普通永磁同步电机设计软件，然后利用ANSYS自带语言编写了两种电机的有限元分析软件，在此基础上对所设计的Halbach电机和普通永磁电机进行了研究。样机实验数据证明Halbach电机在一体化系统中的优越性。
Abstract: Integrated（ISAD Integrated started alternator damper system）vehicle system,motor must have the merits of high efficiency,high power density and low pulsating torque.Halbach motor is a novel permanent magnetic(PM)motor.A sinusoidal field was produced by the special distribution of permanent magnets.The field can increase the air-gap flux while decrease the rotor yoke flux.The result can improve power density and reduce volume of the motor.The paper compiles Halbach motor design software firstly,then give insight research for Halbach motor and traditional permanent magnetic(PM)motor by finite element analysis of ANSYS,Experiment results prove Halbach motor has much more advantages in ISAD vehicle system than traditional permanent magnet motor.
