Soft starters are commonly used to start up AC motor smoothly
and Safely. The AC motor reach the maximum speed in about (10 second to 30
second) depending on the power of the motor.
After the motor reach max speed a control contactor
(on) and bypass the soft starter circuit.
Why we use soft starters
connection is not suitable for high power AC motor
( Dangerous and unstable )
So, we use soft
starter for following advantage:
- Reduce starting consumed power.
- Reduce mechanical wear and tear.
- Eliminate stock and starting stress (smooth acceleration).
- Eliminate fluid coupling and clutches.
- Increase electrical efficiency.
- Cost saving (less maintenance).
