3 Phase Induction Motor Star Delta Connection Diagram Pdf

For example we have a 37w50 hp motor so what will be starting current consumption for this motor and motor is connected in star delta configuration. 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.

Wiring diagram star delta connection in 3 phase induction motor as the name suggests an outline of the wye delta starter works in two stages beginning with the motor running winding circuit wye y after a while the motor release belita circuit wye and delta winding operating with.
