摘要
介绍一种新的(?)三维方法。用这种方法可计算异步电动机起动时的轴向温度场分布。该法能简化三维瞬态温度场的计算并节省计算时间。它还可用来计算起动时导条和端环的温升,具有足够的精度。一般来说,用这种方法计算的温升与试验值是吻合的。
This paper presents a new quasi-3D method which can be used to calculate the axial temperature field of induction motor during start. This method simplifies the calculation of 3D transient temperature field and saves computation time. It can be used to calculate the temperature rise of rotor bar and end ring during start with enough accuracy, In general way, the temperature rises calculated by this method are in agreement with test data.
