摘要:
为了解决500 kW级磁力离合器安装体积大、挂重大的问题,结合等效磁路法和有限元方法,对影响其电磁特性的主要结构参数进行敏感度分析.基于等效磁路方法,建立磁力离合器理论模型,分析结构参数对其电磁特性的影响.根据扇形和矩形永磁体的结构特征及电磁特性,确定永磁体形状的一般选取原则.针对永磁体极对数和占空比、导体盘温升、材料以及导体转子尺寸等主要参数对磁力离合器转矩特性的影响也进行了详细分析.结果表明:结构参数和磁导率主要影响磁路中各元素的磁阻和气隙磁场;导体盘电导率降低1.0×107 S/m,临界转差率增大约0.02;改变单一参数不能大幅提高磁力离合器的最大输出转矩,各参数之间互相影响,共同决定磁力离合器的输出特性.
Abstract:
To solve the problems of 500 kW grade magnetic clutch(MC)installation volume and heavy hanging, the sensitivity of the main structural parameters affecting the electromagnetic characteristics of the MC was analyzed by combining the magnetic equivalent circuit(MEC)method with the finite element method. Based on the MEC method, a theoretical model of MC was established to analyze the influences of structural parameters on the electromagnetic characteristics of the MC. The general selection principles of permanent magnets were determined according to the structural characteristics and the electromagnetic characteristics of fan-shaped and rectangular permanent magnets. The influences of the main parameters, such as the pole pair number and duty ratio of the permanent magnet, the temperature rise of the conductor disk, the material, and the size of the conductor rotor, on the torque characteristics of the MC were also analyzed. The results show that the structure parameters and the permeability mainly affect the reluctance of each element in the magnetic circuit and the air-gap magnetic fields. The critical slip increases by about 0.02 when the conductivity of the conductor plate decreases by 1.0×107 S/m. The maximum output torque of the MC cannot be improved by changing a single parameter. The output characteristics of the MC are determined by the mutual influence of each parameter.
