Hey guys! I need some help. Im a real rookie, and unsure if i tackeled my problem right.
Attached is the circuit im trying to figure out.
Values: ERROR, missmarked some of the resistors: the first R1 and R2 are 4 ohm each, and the other 5-parallel is 75ohms each.
L3 is 82mH, L1 and L2 are 33.3mH each. Capacitors C1 and C3 are 740nF and C2 and C4 are 27nF. We had to is this way to get the values we needed. This is a equivalent circuit for a threephase 400VAC supply. 50hz
I am trying to figure out how much voltage is over the motor, and how much current is going trough the motor. The motor is needed to be supplied with around 7A when it is starting.
I tried to add the first parallel resistors with reactance in the inductor to get the impedance. But do i now put this impedance in parallel with the capacitors C1 and C2, and then in series with the 5-resistor paralell? is should i calculate from the motor and to the left?
Sorry for the bad typing.
Any help is very welcoming!
