In an alternator, if the winding is short pitch by 60° electrical its pitch factor will be
The pitch factor is given by the formula:
Pitch factor = (2/π) x cos(π/6) = 0.866
where π is pi, and cos(π/6) is the cosine of 30 degrees, which is half of the given pitch angle of 60 degrees.
Therefore, the pitch factor of the short-pitch winding is 0.866.
