Characteristics of Asynchronous Induction Motors

The asynchronous induction motor is an AC motor that generates electromagnetic torque by the interaction between the air gap rotating magnetic field and the rotor winding induced current, thereby converting electromechanical energy into mechanical energy. Its main features are as follows:

1.High efficiency

Asynchronous induction motors have high power conversion efficiency and can convert electrical energy into mechanical energy with an efficiency of more than 80%. Compared with traditional excitation DC motors, asynchronous induction motors have greater advantages in high efficiency and can save a lot of energy costs.

2.Good stability

The asynchronous induction motor has stable speed and load characteristics, can maintain a high speed under normal loads, and can adaptively adjust the speed and electric power when the load changes, and has good stability during work.

3.Smooth operation

The asynchronous induction motor runs smoothly, has low noise and low vibration, so it will not affect the accuracy and other aspects of the production process. The gap between the rotor and stator is small and brush-related failures will not occur. This is also one of the reasons why asynchronous induction motors are widely used in industrial production.

4.Easy maintenance

The maintenance and repair of asynchronous induction motors are relatively simple, and there is no need to regularly replace components such as the excitation armature. Moreover, its structure is simple and the manufacturing cost is low, so the cost of replacing parts is also low. In addition, due to the good mechanical durability and long life of the asynchronous induction motor, it has a long service life and reduces maintenance costs in actual industrial production.
