China's motor frequency conversion control energy-saving technology is relatively weak, mainly in two aspects. First, the efficiency of our country's electrical and passive facilities and equipment is low. Although the motors produced in China are at the same level as those produced abroad, they have higher prices and lower market share compared with foreign motors. There is also a certain gap between manufacturing technology and technology. Second, the operating efficiency of our motor system is low. China's motors often have unreasonable system matching, resulting in long-term low-load operation of the equipment. The system regulation of the motor is behind, resulting in the waste of electrical energy. Motor frequency conversion control energy-saving technology can reduce the use of electricity, reduce greenhouse gas emissions, reduce the غير مجاز مي باشدt of business use, and achieve the goal of energy-saving emission reduction.

The application of motor frequency conversion control is in the energy consumption of the motor. The motor frequency conversion control technology can well save the energy consumption of this part of the load and achieve the purpose of energy conservation and emission reduction. Let's take the air conditioner as an example to illustrate it. There is no air conditioner applying the variable frequency control system. When the set temperature is lower than the threshold, it can only be achieved by closing the air way, but at this time, the air conditioner's motor continues to run. Some of the drive power is not used at all, but simply wasted. The need to control the speed of the motor to reduce, reduce the output drive power can be achieved, there is no need to shut down the wind, and it will not waste the motor drive frequency, a good increase in the use of electrical energy efficiency. The power system has vigorously promoted the motor frequency conversion energy-saving control system. The application of this system has greatly eased the current situation of the shortage of electric energy in China. The motor frequency conversion energy-saving control system can reduce the unnecessary drive frequency output of the motor and achieve a reasonable application of power.
