What is a VFD and what does it do?

A Variable Frequency Drive (AKA a VFD), can be used in a lot of fields. A VFD is a type of motor controller that drives an electric motor by the varying frequency and voltage that is supplied to the electric motor. They are widely used to control the speed of AC motors such as conveyor systems, pump speeds, blower speeds or other applications that require variable speed with variable torque.




Why use it?

A VFD is a great energy saver and recognizes automation. You are able to control the amount of air flow, the amount of pressure and the motor can be adjusted according to seasons along with day/night. This helps to conserve unnecessary energy use.

This also can provide higher machine efficiency. Conventionally, the rotation speed of a main spindle on a piece of machinery is controlled by the speed of a pulley. By using a VFD, you are able to make these speed changes simpler. This can result in being able to downsize machines. You can also control the speed to be conducive with what is moving on the conveyor belt. Slowing it down for items that may wobble and fall over, or to go faster with things that can handle the speed, making production time faster.
