摘要
为提高直线磁场调制电机功率因数,通过推导直线磁场调制电机气隙磁通密度、功率因数的解析公式,研究各个结构参数对电机功率因数的影响.确定了永磁体分布、齿靴宽度、调磁块形状和尺寸等参数为主要优化变量.在利用Ansys Maxwell软件对直线磁场调制电机进行参数化有限元仿真的基础上,建立了关于电机平均推力和功率因数的多项式响应面模型.采用Box-Behnken方法对电机进行优化设计,优化后的直线磁场调制电机功率因数从0.497上升到0.720,提高了约44.9%.
In order to improve the power factor of Magnetic-Geared Flat Linear Machine(MGFLM),this paper derives the analytical formulas of its air gap flux density and power factor,and investigates the influence of the variables on the basic physical quantities of the motor.The main variables affecting the power factor are determined as the permanent magnet distribution,the width of the tooth shoe and the shape and dimensions of the magnetizer block.Secondly,based on the parameterized finite element simulation of the MGFLM in Ansys Maxwell,a polynomial response surface model for the average thrust and power factor of the motor is established.Finally,Box-Behnken method was applied to optimize the motor.The power factor of the optimized MGFLM is increased by 44.9%from 0.497 to 0.720.
