When do you need a soft starter for an AC motor?

Nov 21, 2018· A soft starter relies on three pairs of SCRs (silicon controlled rectifiers) — one pair for each phase of power — that are applied gradually for portion of each voltage phase, limiting the voltage provided to the motor In turn, current is reduced proportionally to the reduction in voltage Torque, however, is proportional to the square of the voltage, so even a small reduction in voltage ....

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...
