Reduced Voltage Starters

Reduced Voltage Starters place a device called a soft starter, between the motor and the incoming utility line to regulate the amount of current fed to the motor. Reduced Voltage Starters enable the AC induction motor to speed up in smaller, resulting in less current drawn than with a traditional motor starter.

How does soft start work? As a result the stator draws high current and by the time the motor reaches to full speed, a large amount of current (greater than the rated current) is drawn and this can cause heating up of the motor, eventually damaging it. The starting current can be controlled smoothly by easily altering the starting ...
