I have some attachements below from my textbook. According to it the value of resultant flux is constant in magnitude and 1.5 times the maximum value of flux.
But i have a doubt regarding how it is proved.
The magnetic flux waveforms are 120° apart from each other and at time 0, the instantaneous value of flux waveform of 1st phase is zero. Whereas 2nd phase has magnitude -√3/2.Φm and the third phase √3/2.Φm.The textbook says that:
Φr = 2.(√3/2)Φm.cos60/2
Here is my doubt
If the fluxes are 120° apart, shouldn't the equation be: Φr = 2.(√3/2)Φm.cos120/2 ?
Please explain me in the simple way how this works.i appreciate the help:) [/B]
I know that when forces have same magnitudes then for resultant force we use the formula:
The Attempt at a Solution
I have been trying to think about it and draw a waveform to figure it out but couldn't understand it.
