    • A first analyzing step is a step that conducts numerical analysis of a flow field but does not conduct numerical analysis of a temperature field in a state in which a motor rotor is rotating. The second analyzing step is a step that conducts numerical analysis of both the flow field and the temperature field after the first analyzing step ends. Accordingly, before numerical analysis of the flow field and numerical analysis of the temperature field are conducted together, numerical analysis is conducted first on the flow field in first analyzing step before it is conducted on the temperature field. As a result, compared with when the second analyzing step is executed from the beginning without conducting the first analyzing step, the calculation load of the numerical analysis on an electronic calculator can be reduced, which enables the time that it takes to conduct the numerical analysis to be shortened.
    • 第一分析步骤是在电动机转子旋转的状态下进行流场的数值分析但不进行温度场的数值分析的步骤。 第二分析步骤是在第一分析步骤结束之后进行流场和温度场的数值分析的步骤。 因此,在对温度场进行数值分析和温度场数值分析之前,首先对温度场进行第一分析步骤的流场进行数值分析。 结果,与第一分析步骤相比,从第一分析步骤开始执行时,可以减少电子计算器上的数值分析的计算负担,从而能够进行数值分析所需的时间 缩短。
