Slow Start Stop Revised Version
Method for controlling the starting current of a three-phase induction motor.
This is a guide for control devices for slow start-stop. With the three-phase induction motor (motor) now meeting the IE3 standard, the starting current has significantly increased. When updating fire hydrant pumps or smoke exhaust fans, I've heard that costs rise due to increasing generator capacity, adding inverters, and related harmonic measures. By controlling the voltage for the start and stop of pumps and blowers, the starting current can be reduced, and water hammer can be eliminated.
