估计电动机中的永久磁铁的温度的方法
摘要：
本发明提供一种估计电动机中的永久磁铁的温度的方法，其能够精确估计电动机中所包括的永久磁铁的温度且能够阻止磁铁退磁。具体地，该估计电动机中的永久磁铁的温度的方法能够通过分析永久磁铁温度的变化和基于实际测得的值的每电动机操作条件的转子损耗之间的相互关系导出传热系数，且使用其来构建永久磁铁的热模型以估计永久磁铁的温度，并且，由此能够基于电动机的操作条件精确估计永久磁铁的实时温度。
摘要（英）：

A method of estimating a temperature of a permanent magnet in a motor that is capable of precisely estimating the temperature of a permanent magnet included in a motor and of preventing demagnetization of the magnet is provided. Specifically, the method of estimating a temperature of a permanent magnet in a motor is capable of deriving heat transfer coefficients through an analysis of an interrelation between a variation of permanent magnet temperature and a rotor loss per motor operating condition based on an actually measured value and constructing a heat model of the permanent magnet using the same to estimate the temperature of the permanent magnet, and accordingly, it is possible to precisely estimate real-time temperature of the permanent magnet based on the operational condition of the motor.
