Advanced structure design and technology of three-phase asynchronous motor

1. The advanced structural design and technology of the three-phase asynchronous motor make it small in size, light in weight, high in efficiency, save space, and facilitate the installation and commissioning of the unit.

2. The three-phase asynchronous motor is easy to use and easy to maintain. There are no moving parts in the main body of the motor, so maintenance and inspection are convenient, and there are no leakage and lubrication problems.

3. The three-phase asynchronous motor has good load adaptability and dynamic response characteristics. It has been proved by experiments and applications that the three-phase asynchronous motor has stable performance under the condition of low speed and heavy load, can withstand the impact load well, and its response speed is faster than that of the DC motor.

4. The three-phase asynchronous motor has no permanent magnetic poles during operation, so it is never necessary to modify the magnetic pole position. However, the pole position of the DC motor will move with the increase of the energization time, and the magnetic pole position needs to be frequently adjusted.

5. The three-phase asynchronous motor has good starting characteristics, and can start well even at low voltage, without using special devices.

6. The three-phase asynchronous motor has the advantages of strong speed regulation performance and good adaptability. It can use devices such as power electronic frequency converters to adjust voltage and frequency to achieve variable speed control. In the case of using a frequency converter, not only frequency regulation can be achieved, but also the range and precise control of motor speed can be completed by controlling voltage and current to meet different load requirements and operating states.

7. The three-phase asynchronous motor can be driven individually or in multiple ways to realize the coordinated work of various mechanical equipment, thereby further improving production efficiency, optimizing the production process, and reducing costs.

8. The three-phase asynchronous motor has high operating efficiency and low operating cost. The power factor of the motor itself is very high, generally higher than that of a DC motor. In addition, due to its advanced design and structure, its internal loss and line loss are very small, and the power conversion efficiency has reached a higher level.

9. The three-phase asynchronous motor has high reliability and long service life. Since it has no moving parts that require extensive lubrication and anti-corrosion maintenance, it has a low failure rate. At the same time, its service life is much higher than that of DC motors.

10. Environmental protection and energy saving effect of three-phase asynchronous motor. With the continuous improvement of environmental protection awareness, the requirements for environmental protection and energy saving of electric motors are also getting higher and higher. The three-phase asynchronous motor performs well in energy utilization. Compared with other transmission devices, its energy utilization efficiency is higher, which can ensure the effective utilization of electric energy, reduce environmental pollution, and improve energy utilization efficiency.
