| Abstract: | In order to solve the great starting current and occurrence of water hammer in pump unit, the soft starting controller of motor based on PIC microprocessor was proposed. Working principle of the controller was analyzed, and the constituent of controller and block diagram of software program were provided, and the principal of constant current soft starting was explained. Use of the controller gave an effective solution to the large shock current in starting of the motor, and avoided the occurrence of water hammer, so that the pump unit can run in a safe and reliable way. |
