Answer Posted / haroon

becoz there is 360 degree in a circle and we can have dived
it in 3 equal parts i-e 120degree.the meximum power that we
can generate on in three phase system, let draw a sine wave
of three phase supply when R is on its peak the Y is
behined it by 120 and the blue is bhined R bye270 dgin this
wave 2 phase r +ve at the same time which is needed for
motor rotating which can be +ve if we draw sine wave of 5
or 4 phase generator
