The difference between VFD and Soft Starter

Besides of the motor soft starting, VFD also can control the motor speed, to save energy. Cost: VFD's cost may be as high as triple as the soft starter. If the motor works at full load all the time (means no need to vary the speed), then soft starter is your selection. In other case, say the ball mill works at 80% load, then choose the VFD, the ...

The difference between VFD and Soft Starter

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. In overhead crane controls, setting a soft start to begin traversal motions with a capacity load on the crane or trolley can result in a 'jack rabbit' starting jump when the crane is unloaded.
