溫升是電機產(chǎn)品非常重要的性能指標,而決定電機溫升水平的則是電機各部位的溫度,以及所處的環(huán)境條件。
從測量的角度分析,定子部分的溫度測量相對直接,而轉(zhuǎn)子部分則傾向于間接測量。但無論如何檢測,兩者溫度的相對定性關(guān)系不會有太大改變。
從電機工作的原理分析,電機的發(fā)熱點基本為3個,即定子繞組、轉(zhuǎn)子導(dǎo)體和軸承系統(tǒng),如果是繞線式轉(zhuǎn)子,還有集電環(huán)或碳刷部分。
從熱量傳遞的層面分析,各個發(fā)熱點溫度的高低不同,必然會通過熱量的傳導(dǎo)和輻射,達成各個部位相對意義上的溫度平衡,即每個零部件都表現(xiàn)為溫度的相對恒定。

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.
