The 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 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
