Get PriceThe difference between VFD and Soft Starter
The difference with Soft Starter vs Variable Frequency Drive (VFD) is the method of starting employed. A soft starter reduces voltage not Hertz and as such the starting torque at 2-3 Hz is next to nothing. The soft starter is essentially robbing the motor of voltage at all points between 0 and 59 Hz peak (Line) voltage met at 60 Hz.
