步进电机内部都是由铁芯和绕组线圈组成的

步进电机内部都是由铁芯和绕组线圈组成的。绕组有电阻,通电使用就会产生一定的热量。

Stepper motor inside are composed of iron core and the windings. Winding resistance, electricity use will produce a certain quantity of heat.

其实它就像木工雕刻机的主轴电机一样,温度是不断地会升高,只不过主轴电机有冷却水循环来降低产生的热量。但是步进电机是没有水冷却的,那么如何来判断它的温度过热的问题呢。

It like woodworking engraving machine spindle motor, temperature is continuously rises, spindle motor has only to reduce the heat generated by the cooling water cycle. But there is no water cooling step motor, so how to judge its temperature overheating problem.

其实问题很简单。步进电机发热的合理范围,电机发热允许到什么程度,主要取决于电机内部绝缘等级。

Actually very simple question. Stepper motor heating reasonable range, electrical heating allows to what extent, mainly depends on the internal motor insulation class.

内部绝缘性能在高温下(130度以上)才会被破坏。所以只要内部不超过130度,电机便不会损坏。

Internal insulation performance at high temperatures (130 degrees) will be destroyed. So as long as within no more than 130 degrees, the motor won't damaged.

内部温度我们可能没法准确测量到,但是我们可以测量一下电机的表面温度。当内部温度在130度时,外部会在90度左右。所以,步进电机表面温度在70-80度都是正常的。

We may can't be measured accurately to the internal temperature, but we can measure the surface temperature of the machine. When the internal temperature of 130 degrees, the outside will be around 90 degrees. So, step motor surface temperature in 70-70 degrees are normal.

Simple useful point thermometers, temperature measurement method can also be rough judgment: by hand can touch more than 1 to 2 seconds, no more than 60 degrees; Only with the hand touch, about 70-80 degrees; Drop a few drops of water gasification quickly, more than 90 degrees.
