Abstract:The current in the asynchronous motor when it is starting is very high. It would make great damage to the motor. The softstarter of motor controlled by Single chip can solve this problem. The softstarter of asynchronous motor was designed based on SCM——MSP430F149. The start of the motor can be accomplished by its software. The circuit of the softstarter was very simple. It also has very good stability. The perfect antiinteraction ability makes it be used in industry very well. It would have a great application in future.
Key words: single chip microcomputer(SCM); MSP430F149; softstarter of motor
