Variable frequency drives (VFDs) are increasingly common place in an ever expanding wide variety of applications. VFDs vary motors’ output speeds without the implementation of mechanical pulleys, thereby lowering the number of mechanical components and reducing the need for maintenance. But the real benefit of variable frequency drives lies in their ability to save you money by cutting down energy by consumption by using only the power that is required. But how do variable frequency drives go about doing this?

Energy Saving Variable Frequency Drives

Simply put, these AC Drives can be used  for power conversion. A Variable Frequency Drive is similar to the motor that it is attached to – in that both of these component convert power to a usable forms. Inverters will convert incoming power, which is at a fixed frequency and voltage, to a variable voltage and frequency. Variable speed drives are therefore able to vary the speed of motors without adjustable pulleys or gearing changes.

A Variable Frequency Drive is basically a power conversion tool used to convert fixed incoming power to variable voltages and frequencies. It is worth being mindul of the voltages, currents and power factors of the power supply and these electrical factors’ relationships when comparing VFDs’ inputs to their outputs. Similarly, the same may be true for when utilising motors’ mechical speed and torque to determine the input power and current to the Variable Frequency Drive. Once all these variables have been taken into account, the input current of the system is often found to be much lower than the output current.
