摘要
现代电机要求高速、高效、高功率密度、低脉动转矩;Halbach阵列独特的稀土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间;实验结果证明,Halbach永磁同步电机相对于传统稀土永磁同步电机具有较大的优越性。
Modern motor needs high speed,high efficiency,high power density and low pulsating torque.Halbach array with one-sided and sinusoidal field is produced by special distribution of permanent magnets.The field can increase air-gap flux while decrease rotor-yoke flux and air-gap harmonic,which 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.Experimental results prove Halbach motor has much more advantages than traditional rare earth permanent magnet motor.
