What is a VFD?

Let's look back at what we now know. VFD stands for Variable Frequency Drive. They are used for controlling the speed of an AC motor. They are also used for ramping up a motor for a smooth startup, or to prevent a heavy load from straining the motor on startup. This is accomplished by adjusting the frequency delivered to the motor.

How to choose between VFD and soft starter

25-75 hp or so, the cost of a soft starter is not necessarily lower than the cost of a variable frequency drive. The larger the load, the more cost advantage that a soft starter has, particularly for medium voltage. For an extreme example, the market price of a 25-hp soft starter and a variable-frequency drive are very comparable.
