Application of motor frequency conversion control
About 70% of the energy consumption of the motor is applied to the load of the fan and the pump. Therefore, the motor frequency conversion control technology can save the energy consumption of this part of the load and achieve the purpose of energy saving and emission reduction. . Take the air conditioner as an example. If the air conditioner without the inverter control system is used, when the set temperature is lower than the threshold, it can only be realized by closing the airway. However, the motor of the air conditioner is still running at this time. Some of the drive power is completely unused, but it is simply wasted. However, in the air conditioner that wins the inverter control system, if the temperature of the air conditioner is lowered, it is only necessary to control the rotation speed of the motor to be reduced, and the driving power of the output can be reduced. It is not necessary to turn off the air passage, and it is not necessary. It will waste the driving frequency of the motor and improve the utilization efficiency of the electric energy.
3. Conclusion
In order to comply with the requirements of the national sustainable development strategy, the power system vigorously promotes the motor frequency conversion energy-saving control system. The application of this system has largely alleviated the current situation of China's power shortage. The motor frequency conversion energy-saving control system can reduce the output of unnecessary driving frequency of the motor and achieve reasonable application of power.
