I think In the actual built circuit shown as picture posted, the star contactor is connected to the thermal overload terminal from motor side, which is more safety may be, not from delta contactor side as shown in power circuit diagram.
thanks for your schematics
i made the start delta control circuit in fluid-sim, and i releized that it repeat the cycle when you press the start button again, and as solution i suggested to energize the main contact first.
Wiring connection reference will be near the terminal box of motor or the terminal box cover. This circuit is concept of star start delta run motors. Main supply will be connected to U1, V1, W1 and the configuration of star or delta will be based on the active contactor. Timer is to delay the turning off of the star contactor and delaying the turning on of the delta contactor. But what if the voltage of start is different from the run voltage?
please i need a help. i operate an Ingersollrand air compressor that is controlled by a star delta starter. the motor runs for some minutes and the control circuit will trip but starts when start push button was pressed. also, the timer relay just went off after the compressor ran for 4 cycles. what should i do because one component keeps going off after another. Please advice me. my email is ejike....@yahoo.com. Thanks
sir I want to know that if we are going to connect a motor directly in star or delta connection without a stater thaen how we can make sure that which connection is suitale for the motor star or delta? if star why? if delta why? explain the reason also and explain it for havey motor and also for normal 75 w 3 phase motor
