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?

电机内部绝缘等级决定了电机发热的范围，通常内部绝缘性能承受的范围在130℃左右。只要不高于130℃的话，就不会影响到电机。那我们怎么样测量温度呢，可以用点温计;第二可以用手触摸;第三滴水法，如果水接触电机迅速汽化，就说明温度在九十度以上了。

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 ℃.

电机发热是正常现象，对自身的寿命的影响也是微乎其微的，所以大家不用太过担心。如果，一直太高会造成一些不好的影响，比如电机内部各部分热膨胀系数不同导致结构应力的变化和内部气隙的微小变化，会影响电机的动态响应，高速会容易失步。所以，在我们生产过程中，碰到这种情况，应该把机器停下来让它休息一下，有条件的可以在电机外边安装一个散热器，效果会更加明显。下会产生热能，，如果长时间加工的话就会烫手。那么问题来了，电机能承受多大的热量，怎样减少产生的热量呢？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
