Research on asynchronous motor energy-saving technology

With the social and economic development, human demand for energy is more and more essential. How to achieve energy conservation and emissions reduction effectively has become a worldwide concern. Asynchronous motor in daily life, especially in the industrial production plays a very important role. Asynchronous motor is the main energy consumer. In practice, due to various reasons, the asynchronous motor run frequently under the condition of no load or light load, the condition of motor power factor and the efficiency is low, even the large electric energy waste. If the energy saving of asynchronous motor is in control and the efficiency of the motor is improved, the considerable electricity quantity for increasingly energy conservation will have extremely great significance for our society, nowadays. From the perspective of energy-saving of asynchronous motor, this paper introduces the new situation of the asynchronous motor energy-saving's background, significance and research status at home and abroad. This paper mainly discussed the key technology of asynchronous motor energy-saving and its existing problems and briefly introduced its future development trend.
