What is a Variable Frequency Drive?
Variable Frequency Drives (VFDs), sometimes simply called “drives” in industry jargon, are devices that allow precise control of the speed and torque of an alternating current (AC) electric motor by varying the frequency and current supplied to the motor.
How Does a Variable Frequency Drive Work?
VFDs are typically located between the power supply and the motor. The energy from the power supply flows into the VFD, which regulates the power provided to the motor.
Inside the unit, the incoming alternating current (AC) passes through a rectifier, which converts it into direct current (DC). The DC current is then sent to capacitors inside the VFD. This process smooths out the electrical waveform, providing a clean power source for the next step.
The current is then passed from the capacitors to the VFD, which transforms the DC back into alternating current (AC) to be delivered to the motor. This step allows adjustment of the frequency and voltage that power the motor based on the specific needs of an industrial process.

Some Benefits of Using Variable Frequency Drives
For both large industries and small businesses, there are several benefits to installing VFDs on electric pump systems, fans, conveyors, compressors, and more.
Improved Operational Efficiency
VFD-controlled drive systems can often be automated, leading to savings in labor costs.
Savings on Electricity Costs
VFDs only use the necessary amount of energy, operating motors at partial load, which can result in up to 50% energy savings.
Savings on Maintenance and Spare Parts
VFDs minimize mechanical stress during startup and operation, helping extend the lifespan of your equipment.
