How do VFDs save energy?

Variable frequency drives are widely used in many areas such as fan, pump, compressor, elevator, tower crane, CNC, paper making machine and more. There are many benefits of applying frequency inverter

1. Saving energy: when your production don't need the motor to run at full speed, then you can use a variable frequency drive to adjust the motor running speed, so energy can be saved during the process.
2. Improving the control accuracy: in variable torque or tension control applications, the production needs variable torque or tension, such as paper-making industry, textile industry and etc. By using a frequency inverter, it can help users to control the torque or tension accurately according to the application requirements. Therefore, the production efficiency can be greatly reduced.
3. Reducing the maintenance cost of your equipments : when your production control system is without a frequency inverter, the motor will start instantly with large current which is harmful to your mechanical equipments. A frequency inverter which is developed with motor soft-start function can prevent this phenomena, so the equipment wear will be reduced and the equipment maintenance cost will be decreased also.
