温升是电机产品非常重要的性能指标,而决定电机温升水平的则是电机各部位的温度,以及所处的环境条件。
从测量的角度分析,定子部分的温度测量相对直接,而转子部分则倾向于间接测量。但无论如何检测,两者温度的相对定性关系不会有太大改变。
从电机工作的原理分析,电机的发热点基本为3个,即定子绕组、转子导体和轴承系统,如果是绕线式转子,还有集电环或碳刷部分。
从热量传递的层面分析,各个发热点温度的高低不同,必然会通过热量的传导和辐射,达成各个部位相对意义上的温度平衡,即每个零部件都表现为温度的相对恒定。

Temperature rise is a very important performance indicator for motor products, and the temperature of each part of the motor and the environmental conditions it is located in determine the level of temperature rise.
From a measurement perspective, the temperature measurement of the stator part is relatively direct, while the rotor part tends to be measured indirectly. However, regardless of the detection, the relative qualitative relationship between the two temperatures will not change much.
From the analysis of the working principle of the motor, there are basically three hotspots of the motor, namely the stator winding, rotor conductor, and bearing system. If it is a wound rotor, there is also a collector ring or carbon brush part.
From the perspective of heat transfer, the temperature of each heat source varies, and it is inevitable that through the conduction and radiation of heat, the relative temperature balance of each part will be achieved, that is, each component will exhibit a relatively constant temperature.
