When we found out Three-phase asynchronous motorWhen we can't start, we can judge the reasons for not turning through some methods, and we can check and find out the reasons from the following points Mori machine小编一起了解下吧。

Three-phase asynchronous motorIn terms of structural differences, it can be divided into squirrel cage type and winding type. Compared to a single motor, Three-phase asynchronous motorThe operation performance is better, more economical in the material above, and below Mori machine小编简单了解一下它是如何分类的：

Torque motorThe working principle is the same as that of squirrel cage induction motor; In the structure of the rotor resistance is larger than the squirrel cage motor, then the difference between the two in addition to the rotor resistance and what are the differences, it is interesting to follow Mori machine小编一起学习下吧！

In industrial and agricultural production operations Three-phase asynchronous motorHas been widely used, the fault is also different; Among them, the lack of phase operation is the common fault of the motor, below and Mori machine小编一起来了解下什么原因会导致电机缺相运行，这时的电机又会怎么样？

Torque motors are widely used in the industrial field, mainly for winding and unwinding operations. When the diameter of the drum of the item is larger, the heavier the load, the greater the power required in the winding process, and the winding speed will be reduced and slowed down to meet the power needs of the winding system.

We know the three-phase alternating current phase difference120°This is also Three-phase asynchronous motor机其叫“异步”不叫同步的原因，比较单相交流电有很多优点，比如发电、输配电以及电能转化为机械能方面都有明显的优势。

The temperature rise and allowable working temperature of this line group of different insulation grades of motors. Today, Senli Motor, the torque motor manufacturer, will take you to understand some of the differences about insulation grades, taking insulation grades (E, B, H, F) as an example. A simple introduction to the material, working temperature, wire group temperature rise and performance reference temperature of the torque motor insulation grade, together to understand it!

Three-phase asynchronous motorIt can be divided into two types: cage type and winding type. The cage type rotor is relatively simple in structure, reliable in operation, light in weight and cheap in price, and has been widely used in production operations. Below follow Senli Motor Xiaobian to understand about it Three-phase asynchronous motor的特性：

Customer is buying Torque motorWhen you wait for motor equipment, you will see the concept of insulation class. To order one Torque motor YLJ100Series for example: Our insulation customization grade is (ELv.,BLv.,HLv.,F级）那么这些等级是什么意思，又是如何划分的，下面我们就一起来看下：

The motor uses the principle of electromagnetic induction to realize the conversion of electrical energy and mechanical energy. It is mainly used in modern industrial production Three-phase asynchronous motor. Let's briefly understand its structure: the motor is mainly composed of the stator and the rotor, the fixed part is called the stator, the rotating part is called the rotor; On account of Three-phase asynchronous motor的定子产生励磁旋转磁场，同时从电源吸收电能，并产生且通过旋转磁场将电能转换成转子上的机械能；定子与转子之间须有一定空间隙，称为空气隙来保证转子的自由转动。
