When the drive motor is stopped, the traditional control methods are accomplished through a momentary power failure. But there are many applications do not allow the motor instantly shut down. For example: high-rise buildings, water pump system of the building, if the instantaneous stop, will have a huge "water hammer" effect, making pipes, pumps or even damaged. To reduce and prevent "water hammer" effect servicing the drive needs to gradually shut down the motor, that soft stop, soft starters to meet this requirement. In the pumping station inverter brands, application of soft stop technology can avoid the "beat the door" damaged pumping stations, reduce maintenance costs and maintenance workload. Soft starter is used to power the motor to reduce the large current to the motor when starting grid impact. It works are added in their specific start time, full voltage from 0V to complete the boot process of the motor; the inverter is to change the frequency of the output of the power supply to achieve the speed adjustment of the motor, under normal circumstances it is used in the speed of the equipment requirements Drive on principle, of course, it can also achieve normal boot process of the motor. Why have soft-start it: because the devices do not require high-power motor speed, in order to start the process to better reduce damage to electrical equipment and power use (such as: high-power fans, pumps, etc.). At the same time with much less power than the price of the soft starter drive. Inverter manufacturers, Yueyang Ohm Electric (certified), Jingdezhen drive by Ohm Electric Co., Yueyang City.
