溫升是電機(jī)產(chǎn)品非常重要的性能指標(biāo)，而決定電機(jī)溫升水平的則是電機(jī)各部位的溫度，以及所處的環(huán)境條件。
從測(cè)量的角度分析，定子部分的溫度測(cè)量相對(duì)直接，而轉(zhuǎn)子部分則傾向于間接測(cè)量。但無(wú)論如何檢測(cè)，兩者溫度的相對(duì)定性關(guān)系不會(huì)有太大改變。
從電機(jī)工作的原理分析，電機(jī)的發(fā)熱點(diǎn)基本為3個(gè)，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(gè)發(fā)熱點(diǎn)溫度的高低不同，必然會(huì)通過(guò)熱量的傳導(dǎo)和輻射，達(dá)成各個(gè)部位相對(duì)意義上的溫度平衡，即每個(gè)零部件都表現(xiàn)為溫度的相對(duì)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.
