The vibration of common asynchronous motor caused by electromagnetic force and mechanical transmission becomes more complicated in the variable frequency motor. The various time harmonics in the variable frequency power supply interfere with the inherent space harmonics of the electromagnetic part, and the fan motor forms various electromagnetic exciting forces. At the same time, due to the wide frequency range of motor, speed change, when it is consistent with the mechanical part of the natural frequency, Yellowstone Fan Motor, resonance. Under the influence of electromagnetic force and mechanical vibration, the motor insulation is subjected to more frequent cyclic alternating stress, which accelerates the aging of the motor insulation. After the sustainable development strategy was proposed, many enterprises and institutions are working hard to realize the low-carbon and energy-saving environment-friendly life in the future. Energy-saving and emission-reduction is an important measure to realize sustainable development strategy. In power system, Fan Motor factory mainly implements energy-saving and emission-reduction for fans, motors and pumps. In order to achieve this goal, the research and development of AC motor variable frequency speed control power saving technology. Asynchronous motor is widely used in industry and agriculture of our country, and it has many disadvantages, such as low power factor, poor speed regulation ability and high energy consumption, etc. . The application of the motor frequency conversion energy saving technology to the asynchronous AC motor can solve these problems AC motor. AC motor is well able to achieve the asynchronous energy saving and emission reduction work, to contribute to China's sustainable development strategy.
