Ac three-phase asynchronous motor can be used as a generator, as long as the rotor is rotating, the rotor rotation is driven by other energy, the rotor rotates in the stator's magnetic field; At this time, the rotor (that is, the closed circuit) is affected by the stator's magnetic field, which generates a current and becomes a generator.

The torque motor used in production sometimes produces noise, and the noise generated is a tricky thing to eliminate, which is usually used as a quality standard for assessing products. Today, Senli Motor Xiaobian will take you to analyze the causes of motor noise.

The three-phase symmetrical winding of the three-phase asynchronous motor will generate a rotating magnetic field with a speed of n1=60f/p in the air gap after the three-phase AC is connected. n1 represents the speed, f represents the frequency, the power supply frequency in China is 50Hz, p represents the number of magnetic poles, this is in pairs, 2P motor only 1 pair of magnetic poles.

Speaking of the application of torque motor, what industry is it generally used in? Due to the different parameter design, its mechanical characteristics and uses can be divided into two categories: winding characteristics and constant torque characteristics. So today, Senli Motor Xiaobian introduces its characteristics and application scenarios according to these two characteristics.

How to wire the three-phase asynchronous motor is also a very hot topic, so today, Senli Motor Xiaobian will let you master the method of this motor wiring, and you can understand it by looking at the picture!

Three-phase asynchronous motors have the difference between star connection and triangle connection. When we measure motor insulation, we must first distinguish what connection method is used. Below is a small series of motors to understand it!

In many industries, it is necessary to wind the product on the drum, and the torque motor can meet the changes in tension and speed within the allowed range, without the need to increase a variety of auxiliary equipment in the mechanical structure or use some other transmission systems to achieve.

We can use a dial to shake, 500V dial can shake the insulation resistance of the line on the three terminals to the motor housing, if it is above 0.5M ohms, it means that there is no short circuit to the ground.

Torque motor has a wide range of applications, and many manufacturers have applied it in winding operations; Because of its constant torque load characteristics, speed can be adjusted. How to choose this motor has become a problem for many manufacturers. Today, Senli Motor Xiaobian and everyone will learn about the choice of this motor.

We simply understand the structure of the three-phase asynchronous motor, mainly composed of the stator of the static part and the rotor of the rotating part of the two important parts, we know the respective roles and relationships of these two parts, to understand the role of the rotating magnetic field:
