摘要:
基于三维运动涡流场的有限元模型,分析了永磁涡流联轴器的电磁场分布,进而计算出主从转轴传递的功率和转矩.并研究了永磁体和铜盘的尺寸对装置特性的影响,得到永磁涡流联轴器的初步优化设计方案.永磁体占空比a确定在0.7左右; 永磁体厚度hm选在其与输出功率P的关系曲线的拐点处较为合适; 确定永磁极对数时,应根据不同的永磁体占空比确保扇形永磁体平均半径处的弧长l与径向宽度wm之比在相应范围内; 铜盘厚度hcu在6～9mm范围内选取; 铜盘内外径应根据铜盘径向宽度wcu与wm比值在1.2～1.6之间确定.最后通过样机实验验证了计算方法的正确性.
Abstract:
Based on a finite element model of three-dimensional moving eddy current field, the electromagnetic field distributions of permanent magnet eddy current coupling are analyzed and the power and torque transferred between motor shaft and load shaft are calculated. Using this model, the influences of main dimensions of the permanent magnets(PM)and copper discs on the characteristics of permanent magnet eddy current coupling are numerically investigated. The primary optimal design project of permanent magnet eddy current coupling is obtained. The ratio of PM can be determined to be about 0.7. The appropriate thickness of PM should be chosen according to the inflexion of the relationship curve between the output power and the thickness of PM. When determining the number of pole pairs, different ratios of PM should be taken into account to ensure that the ratio of the arc length at the position of fan-shaped PM average radius to the radial width of PM is within the corresponding range. The thickness of copper discs should be chosen from 6 to 9 mm. The inner and outer radii of copper discs should be determined by the condition that the ratio of the radial width of cooper plate to the radial width of PM ranges from 1.2 to 1.6. An experiment system is tested to validate the correctness of the model and numerical analysis.
