摘要
随着新能源汽车驱动电机的高速化发展,电机损耗及其导致电机温度升高的问题受到了广泛关注。硅钢材料作为驱动电机铁心的主要材料,参与电磁能量的传输和转换,同时产生铁心损耗。这是电机设备的主要损耗,直接影响了电机的效率,且随着电机高速化发展,铁心损耗占比也更大。因此需要准确分析和计算硅钢材料的铁心损耗。通过对取向硅钢、无取向硅钢、超薄硅钢和高强硅钢4种常用或具有高速电机应用潜力的硅钢材料的铁心损耗的测试,分析了不同频率下其损耗变化规律。基于损耗分离模型,分析了磁场频率对铁损模型磁滞损耗系数和涡流损耗系数的影响,为硅钢材料的铁心损耗的计算及损耗模型的优化提供了参考。
With the high-speed development of drive motors for new energy vehicles,the core loss and its resultant increase in motor temperature have received widespread attention.Silicon steel material as the main material of the drive motor core,involved in electromagnetic energy transmission and conversion,while generating core loss.This is the main loss of motor equipment,which directly affects the efficiency of the motor,and with the development of high-speed motor,the core loss accounts for a larger proportion.Therefore,it is necessary to accurately analyze and calculate the core loss of silicon steel materials,through the test of the core loss of four kinds of silicon steel materials commonly used or with the potential of high-speed motor application of oriented silicon steel,non-oriented silicon steel,ultra-thin silicon steel and high-strength silicon steel,and analyzed the change rule of its core loss at different frequencies.Based on the loss separation model,the influence of magnetic field frequency on the hysteresis loss coefficient and eddy current loss coefficient of the iron loss model is analyzed,which provides a reference for the calculation of the core loss of silicon steel materials and the optimization of the loss model.
