摘要:
针对提高永磁电机温升计算准确性的问题,提出一种计及永磁体涡流损耗分布特性的实时热计算方法。依据温度对电机内各材料属性有所影响,且永磁体涡流损耗有其特有的分布特性的事实,提出并采用计及永磁体涡流损耗分布特性的实时热计算方法,以一台10 kW 变频驱动永磁
同步电动机为例进行实例计算,与普通未计及永磁体涡流损耗分布特性、没有使用实时热计算方法的温升计算方法对比,经在线温升测量,验证了计及永磁体涡流损耗分布特性的实时热计算方法能有效提高温升计算的准确性,可使计算结果与实验结果之间的误差缩小到0. 5%之内。
Abstract:
?For the problem of improving accuracy of temperature rise for permanent magnet ( PM) motor,a real time thermal calculation method under consideration of distribution of permanent magnet ( PM) eddy current loss was presented. Based on the fact that the properties of each motor material are influenced by temperature and distribution of PM eddy current loss have unique characteristics,a method of real time thermal calculation method under consideration of PM eddy current loss was presented and adopted into a 10 kW permanent magnet synchronous motor ( PMSM) driven by variable frequency equipment,which is an example. Compared with general temperature rise calculation method without consideration of distribution of PM eddy current loss and does not use real time thermal calculation method, through the on-line temperature rise measurement,accuracy of real time thermal calculation method under consideration of the distribution of PM eddy current loss is verified that it can reduce the calculation results and experiment results into 0. 5%.
