Soft Starter In Industrial Applications
Introduction to Soft Starter. An induction motor connected directly to the power supply draws a constant magnetizing current at full speed, no matter what the load is. At anything less than full load, power factor of the induction motor is less than its rated power factor because the torque producing current decreases as the load decreases, but the magnetizing current …

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 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.
