A star delta starter is the most commonly used method for the starting of a 3 phase induction motor.In star delta starting an induction motor is connected in through a star connection throughout the starting period. Then once the motor reaches the required speed, the motor is connected in through a delta connection.Motor controller
A small motor can be started by simply plugging it into an electrical receptacle or by using a switch or circuit breaker. A larger motor requires a specialized switching unit called a motor starter or motor contactor.When energized, a direct on line (DOL) starter immediately connects the motor terminals directly to the power supply.Starting of Three Phase Induction Motor | Electrical4U
Where, V L is line voltage. Therefore voltage is reduced at each phase at starting and hence current is reduced. As soon as motor achieves certain speed, motor winding is connected in delta fashion such that line voltage is equal to phase voltage with the help of two way switch. The star delta starter is used for starting of induction motor above 5 H.P.Wiring Up a Brooke Crompton Single phase Lathe Motor ...
Some installations use a DOL motor starter (Direct On Line) instead of a simple on off switch. There are various configurations the one pictured has a starter switch (circuit breaker contactor) with an NVR (No Volt Release) and an overload relay which will 'trip' out if too much continuous current is drawn (but not 'trip' during the starting phase which demands more current).REFRIGERATION AND AIR CONDITIONING rrbbnc.gov.in
