ELECTRONIC MOTOR STARTER
This motor starter protects singlephase motors against voltage fluctuations and overloading. Its salient
feature is a soft on/off electronic switch for easy operation. The transformer steps down the AC
voltage from 230V to 15V. Diodes D1 andD2 rectify the AC voltage to DC. The unregulated power supply is given to the protection circuit. In the protection circuit, transistor T1 is used to protect the motor from over-voltage. The over-voltage setting is done using preset VR1 such that T1 conducts when.........
