FAQ:

Q: What does an inverter do on a VFD?

A: An inverter controls the speed of the main drive motor . Also called a VFD (variable frequency drive) or AC Drive, they change the frequency of the three phase AC power going to a three phase AC motor. The RPM of a three phase AC motor varies with the frequency of the electric power.

Q: How is frequency inverter saving energy?

A: Frequency inverter always saves energy and this energy saving varies from application to application. … If in case,you have process flow and data of pressure,and pump or fan,you can easily find the amount of energy saved using affinity law. By knowing the time of Loading and unloading cycle for compressor will help you to save energy. …

Q: What is an inverter or variable speed drive?

A: Converter: A full-wave rectifier that converts the applied AC to DC. DC bus: Also referred to as a DC link,connects the rectifier output to the input of the inverter. … Inverter: The inverter takes the filtered DC from the DC bus&converts it into a pulsating DC waveform. …

Q: What is VFD, how it works?

A: How Do VFDs Work? The adjustable flow method changes the flow curve and drastically reduces power requirements. Variable frequency drives (VFDs) convert constant frequency and voltage input power to an adjustable frequency and voltage source for controlling the speed of alternating current (AC) induction motors.
