Hello,
I have got a three phase motor connected in delta that is controlled in six step commutation. When I measure the line current of one of the phase under oscilloscope, I got something like this :
Can anyone tell me why the amplitude of the current isn't 3.1A and -3.1A? What I got here is 3.1A and -4.1A which is not symetrical.
