【摘要】 混合动力汽车要求电机高效、高功率密度、低脉动转矩,普通电机显示出了其局限性;Halbach电机独特的永磁体结构使其磁极磁场呈单边且正弦分布,可增加气隙磁通密度、削弱转子轭部磁通密度,减少磁场谐波,有利于提高电机的功率密度和效率、减小电机的体积和脉动转矩;基于MATLAB的Halbach电机设计软件和基于ANSYS有限元分析软件极大地减少了样机设计时;有限元分析及实验结果说明Halbach电机相对于普通永磁电机有较大的优越性。更多还原

【Abstract】 Motor needs high efficiency,high power density and low pulsating torque in hybrid electric vehicle,traditional motors have their limits;Halbach motor’s magnetic field is one-sided and sinusoidal,which is caused by special distribution of permanent magnets.The field can increase air-gap flux while decrease rotor-yoke flux and air-gap harmonic,the results can improve power density and efficiency,reduce volume and pulsating torque of motor.Halbach motor design software based on MATLAB and finite element analysis software based on ANYAS reduce period of motor design greatly;Finite element analysis and experiment results prove Halbach motor has much more advantages than traditional permanent magnet motor.更多还原
