The mechanical degrees in one revolution are 360°.
The electrical degrees are given as
\({\theta _e} = \frac{P}{2}{\theta _m}\).
Where,
P is the number poles
θm = mechanical degrees
θe = electrical degrees
Calculation:
Given
P = 4
θm = 360o
\({\theta _e} = \frac{P}{2}{\theta _m}\)
\({\theta _e} = \frac{4}{2} \times 360^\circ\)
θe = 720 degree
