One is the main contactor which will be always on after starting the motor. Control 3 phase motor from more than two places power control diagrams.
Motor Star Delta Starter Working Principle
Power and control circuit of star delta starter. Star delta starter plc program and wiring part 3 duration. The star contactor is used to make star connection. In the power circuit of star delta starter three contractors are used. This way the circuit is completed as a result. The other contactors are star contactor and delta contactor. Star delta starter control and power circuit diagram.
From l1 the phase current flows to thermal overload contact through fuse then off push button on push button interlocking contact 2 and then c3. In the diagram of power circuit of star delta starter u2 and v2 of 3 phase motor should be connect to 4 and 6 respectively instead of u2 and v2 are connected to 6 and 4 of delta contector km2. Operation working of automatic star delta starter. Stardelta starter without timer power control diagrams wiring diagrams. There is minor correction is require to change printed in boxes sequence of 3 phase wires from w2 v2 u2 to w2 u2 v2 to get delta connection properly.
