　　With the growth of energy saving and emission reduction, in the fan or water pump machinery manufacturing industry, the timing of recycling variable frequency speed regulation electricity will save more electricity than high-efficiency motors.The following is how the motor manufacturer saves electricity.

　　Recycling the frequency conversion speed control technology to drive the frequency conversion speed control motor, and conduct the speed control operation according to the equipment utilization conditions, which can almost save electric energy.The inverter controls the output frequency, so that the variable-frequency speed-regulating motor can perform speed-regulating operation according to the output frequency, so that the working current of the variable-frequency motor will always run between 80%, 50%, and 30% of the rated power, which greatly reduces the frequency-conversion motor. To achieve the goal of energy saving.

　　If two machines with the same power drive the same load, one is a high-efficiency motor and the other is a variable-frequency speed-regulating motor, and both work in the 50Hz power frequency state, the variable-frequency motor can eliminate the excessive starting current when starting. For ordinary high-efficiency motors, the starting current is 5-7 times that of variable-frequency motors.

　　In this environment, the variable frequency speed control motor can save energy, because the frequency converter can soft start the frequency conversion motor (maybe the V/F operation method, in fact, the main goal of the frequency converter is to change the motor through its unique conditions. Starting and running methods, in a certain sense, it is simply more energy-saving than the motor load without the inverter; it is only slightly higher in efficiency and power factor than other speed-regulating equipment.

　　Furthermore, whether the operation of the variable frequency speed control motor can achieve power saving is determined by the speed control characteristics of the load.For loads such as centrifugal fans and centrifugal water pumps, the torque is proportional to the square of the speed, and the power is proportional to the cube of the speed.As long as the reciprocating valve controls the flow and it is not at full load, it can be changed to speed control to save electricity.

　　When the inverter is operated to reduce the speed of the variable frequency three-phase asynchronous electric motor to 80% of its original value, the power is only 51.2% of its original value.It can be seen that the application of variable frequency speed regulators in this type of load has obvious results in terms of power saving.The main impregnation of the frequency converter is speed regulation and soft start.Power saving is a side effect.
