一般温度的测量，只考虑对流换热对热电偶测温的影响，未考虑热辐射对热电偶测温的影响。

General temperature measurement only considers the effect of convection and conduction on the thermocouple measurement and not consider the effect of thermal radiation.

但是由于其周围温度环境(辐射、热传导及对流状况等)与电机内部的发热规律不一致，所以不能对电动机进行有效的保护。

But because of the temperature environment (radiation, heat conduction and convection) and the internal heat of the motor is not consistent, so we can not effectively protect the motor.
