摘要
针对车辆主动悬架能耗严重,以及为实现能量回收的目的,提出一种基于永磁直线电机直驱式发电装置。直线电机采用12槽14极分数槽结构设计。首先,本文分析了空载反电动势和气隙磁通密度,并通过理论计算和有限元仿真对比,发现两者结果均相互吻合良好,印证了所建模型的正确性;其次,通过设置外围电路,研究直线电机的馈能特性,研究结果表明:电机输入、输出功率、绕组电流和反向电磁力与外设负载电阻和电机运行速度相关,电机馈能效率随电阻的增加而增加,并趋向于稳定,但随速度的增加成2次方增加。
According to the disadvantage that there is a heavily energy- consumptive of the active suspension,a permanent magnet linear generator(PMLG) using direct-driver energy recovery device is proposed,which has a fractional slot structure of 12 slots 14 poles.Firstly,No-load electromotive forces and air gap flux density are analyzed respectively through finite element analysis and calculating the theoretical model,it is found that the two parameters agree well with each other,and the finite element model has also been verified.Secondly,energy regenerative characteristic of PMLG is studied with building an external circuitry,the results show that input power,output power,winding currents and reverse electromagnetic force are related to the load resistance and its speed.The efficiency of energy recovery becomes larger with the increased load resistance,and becomes square increasing with the speed.
