With the continuous improvement of the performance and stability of stepping motor, it is widely used in all walks of life, especially in stone carving machine. Because its internal structure is composed of iron core and winding coil, with the continuous improvement of stepper motor performance and stability, it is widely used in all walks of life, especially in stone carving machine. Because its internal structure is composed of iron core and winding coil, heat energy will be generated when it works, and it will be hot if it is processed for a long time. So the question is, how much heat can the motor bear and how to reduce the heat generated?

電機(jī)內(nèi)部絕緣等級(jí)決定了電機(jī)發(fā)熱的范圍，通常內(nèi)部絕緣性能承受的范圍在130℃左右。只要不高于130℃的話，就不會(huì)影響到電機(jī)。那我們?cè)趺礃訙y(cè)量溫度呢，可以用點(diǎn)溫計(jì);第二可以用手觸摸;第三滴水法，如果水接觸電機(jī)迅速汽化，就說(shuō)明溫度在九十度以上了。

The internal insulation level of the motor determines the heating range of the motor, usually the maximum range of internal insulation performance is about 130 ℃. As long as it is not higher than 130 ℃, it will not affect the motor. How can we measure the temperature? First, we can use a thermometer; second, we can touch it by hand; third, if the water contacts the motor and vaporizes rapidly, it means that the temperature is above 90 ℃.

電機(jī)發(fā)熱是正?，F(xiàn)象，對(duì)自身的壽命的影響也是微乎其微的，所以大家不用太過(guò)擔(dān)心。如果，一直太高會(huì)造成一些不好的影響，比如電機(jī)內(nèi)部各部分熱膨脹系數(shù)不同導(dǎo)致結(jié)構(gòu)應(yīng)力的變化和內(nèi)部氣隙的微小變化，會(huì)影響電機(jī)的動(dòng)態(tài)響應(yīng)，高速會(huì)容易失步。所以，在我們生產(chǎn)過(guò)程中，碰到這種情況，應(yīng)該把機(jī)器停下來(lái)讓它休息一下，有條件的可以在電機(jī)外邊安裝一個(gè)散熱器，效果會(huì)更加明顯。下會(huì)產(chǎn)生熱能，，如果長(zhǎng)時(shí)間加工的話就會(huì)燙手。那么問(wèn)題來(lái)了，電機(jī)能承受多大的熱量，怎樣減少產(chǎn)生的熱量呢？1

Motor heating is a normal phenomenon, the impact on its own life is very small, so we need not worry too much. For example, if the internal thermal expansion coefficient of the motor is too small, it will affect the dynamic response of the internal part of the motor. Therefore, in our production process, in this case, we should stop the machine and let it have a rest. If possible, we can install a radiator outside the motor, and the effect will be more obvious. It will produce heat energy, and it will be hot if it is processed for a long time. So the question is, how much heat can the motor bear and how to reduce the heat generated? One
