The synchronous speed and the RPM are not matching there is an additional factor of 2.
The RPM is 200 and the calculation of the frequency is N = 120f/p
p = number of pole pairs = 24
200 = 120 * f / 24
f = 40 Hz but if i measure the hall signal frequency it is 80Hz
Please help me why is there a difference?
f / pp * 60 = 80 / 24 * 60 = 200
