I'm having a little basic problem here.
I'm trying to reconnect the coils of a 4 pole motor (concentric winding) to make a 2 pole motor.
I've managed to make it work in 2 configurations so far (in two different voltages), but the one thing I never get is the fact the sum of the currents (main + aux) is always resulting in less than the greatest one.
In other words, the phase difference is always well above 90º.
If it was 90º, -90º, -270º or 270º the total current would always be bigger than the greatest current (and if both were identical it would be sqrt(2) that current).
But according to the phasor sum I made it's always like 130º, 140º, 150º out of phase etc.
I tested caps from 4 uf to 100 uf and tested several configurations but I never got a 90º difference.
Am I wrong to expect a 90º difference to begin with?
