Reduce the starting current: When the single-phase motor is directly started, the starting current is usually large, which may cause an impact on the power grid, resulting in voltage fluctuations, affecting the normal operation of other equipment. By gradually increasing the input voltage of the motor, the soft starter makes the motor starting current rise linearly from zero to the set value, effectively reducing the starting current and avoiding the impact on the power grid.
Reduce starting stress: The traditional direct starting mode will make the motor bear greater mechanical stress at the start moment, which is easy to cause damage to motor windings, bearings and other components. The soft starter realizes smooth starting, so that the starting torque of the motor gradually increases, the speed also gradually increases, thus reducing the starting stress of the motor and load equipment, and extending the service life of the motor and related equipment.
Soft shutdown: The soft shutdown function is the opposite of the soft start process, the voltage is gradually reduced, the speed is gradually reduced to zero, avoiding the torque impact caused by free parking, which can effectively solve the parking surge problem of the inertial system, especially suitable for some occasions with high parking requirements, such as the water supply system of high-rise buildings, to prevent the production of water hammer effect and reduce equipment damage.
