If this is a single phase generator , how are we considering the angle to be 120 degrees?

In three phase generators we will consider the angle between three coils should be 120 degrees.

We know N = 120F/P.
SO F = N*P/120.
Here n = 400rps(revolution per second).
n = 400*60rpm(rps=Hz=60*rpm).
Thus,
F = 400*60*2/120.
F = 400Hz answer.
SO F = N*P/120.
Here n = 400rps(revolution per second).
n = 400*60rpm(rps=Hz=60*rpm).
Thus,
F = 400*60*2/120.
F = 400Hz answer.

n= 120*f/p.
n : rapid per minute.
f: frequency.
p:no of poles.
n=400*60(rps) =24000(rpm).
f=n(rpm)*p/120.
f=24000*2/120.
f=400 HZ.
n : rapid per minute.
f: frequency.
p:no of poles.
n=400*60(rps) =24000(rpm).
f=n(rpm)*p/120.
f=24000*2/120.
f=400 HZ.

n(rps) = 400 rps.
p(pole) = 2.
f = (pn/2).
f = (2*400/2) => 400Hz.
p(pole) = 2.
f = (pn/2).
f = (2*400/2) => 400Hz.

Since f=1/T.
Here f is frequency.
T is time in seconds.
Here f is frequency.
T is time in seconds.

p = 2.
n = 400.
rps its converted in to rpm its value is 6.66 rpm.
Then f = pn/120.
= 2*6.66/120.
= 0.111 hz.
n = 400.
rps its converted in to rpm its value is 6.66 rpm.
Then f = pn/120.
= 2*6.66/120.
= 0.111 hz.

Where 1sec=1/60min. But how you multiplied 60 in the speed.
