Soft Starters place a device called a reduced voltage starter, or soft starter, between the motor and the incoming utility line to regulate the amount of current fed to the motor. Soft Starters enable the AC induction motor to speed up in smaller, resulting in less current drawn than with a traditional motor starter. Due to decreased voltage, torque is also reduced resulting in a soft, or easy start.
A typical NEMA design B motor can draw six to eight times its full load operating current when it's first started. If the utility's power distribution network is loaded to capacity, the current inrush from starting up large motors can result in anything from flickering lights to brownouts. It can also result in nuisance tripping of circuit breakers and protective devices on the system. Many utilities impose limits on the amount of power customers can draw at any one time, enabling a balance in their distribution system. Reducing voltage to motor terminals at startup reduces the current surge.
