A Variable Frequency Drive (VFD) is a type of motor controller that drives an electric motor by varying the frequency and voltage supplied to the electric motor. A VFD is also called a variable speed drive, adjustable speed drive, adjustable frequency drive, AC drive, microdrive, and inverter.
One of the biggest advantages of using a VFD is the energy cost savings associated with speed control. When you use belts, sheaves, or gearboxes to reduce speed, the motor still runs at full speed. A VFD will reduces the actual motor speed, which results in a reduction of the amps drawn by the motor. The amount of energy used is reduced and saves you money on energy costs.
By ramping up the motor speed slowly, VFDs also help customers save energy by reducing the in-rush and mechanical issues associated with starting motors across the line.
A VFD can save you money by increasing the efficiency of your AC motors and decreasing electricity use. The amount of energy that a VFD can save depends on the average load of the motor and the number of hours per day it is turned on.
The initial cost of a motor or VFD is generally only a fraction of the cost of operating the motor for its lifetime. A VFD system usually pays for itself in a matter of months or just a few years.
Not to be overlooked, a VFD can save you money by extending the life of your motor. VFDs decrease the fluid flow into an AC motor, which in turn decreases the pressure and friction on the valves and other machinery inside the motor. This will help reduce the wear and tear on your motor, thus extending the life of your equipment.
When you operate your motors at the most efficient speed for your application, fewer mistakes will occur. Production levels will increase, while earning your company higher revenues.
