According to the current, our country industry is a major part of social power, electricity and electrical energy consumption in industrial occupied the main position, therefore, the future motor energy saving potential is tremendous. High efficiency and energy saving technology and equipment is important one annulus.

      In addition, the motor repair think efficient prospects. According to the allowable value of small and medium-sized three-phase asynchronous motor efficiency and energy saving evaluation ", the motor efficiency can be divided into 3 in our country, the level of energy efficiency for the ultra high efficiency motor, energy efficiency level 2 for efficient motors, the energy efficiency level 3 for general motors.

      The motor drive technology industrialization way and countermeasure research report shows that 66% of the total electricity consumption in our country on the motor, all kinds of motor efficiency 10 ~ 20% lower than the foreign advanced level.

      Because of the frequency converter can be according to the actual need to adjust the motor speed in real time, can make the motor run under the most energy-efficient speed, can greatly reduce the consumption of electrical energy for light carriage row, and obviously reduce the comprehensive power of the motor running, its energy saving effect obviously, general power saving rate was 20% ~ 20%, the highest even more than 50%, investment capital is recovered in 2 years.

      Compared with the ordinary motor, motor by using high quality materials and the optimization design, the average energy consumption fell 20%, while super-efficient motor loss more than 30% less than normal motor power, high efficiency motor price is more expensive than ordinary Y series motor 15% ~ 30%. But, in general, efficient motor is higher than normal investment can be back in 2 years, in the whole life cycle, can save electricity for the enterprise.

      Improving the efficiency of the motor can be mainly through two ways, one is by frequency converter speed control, improve the operation efficiency of ac motor; The second is using efficient motor. Therefore, specific to the energy-saving equipment, high voltage inverter market and efficient motor market scale is significant.
