A 3 – phase 4 – pole alternator has 48 stator slots carrying the 3 – phase distributed winding. Each coil of the windings is short chorded by one slot pitch. The winding factor is given by
1
\(\frac{1}{{16}}\cot \left( {{{7.5}^0}} \right)\)
2
\(\frac{1}{8}\cot \left( {{{7.5}^0}} \right)\)
3
\(\frac{1}{{16\sin \left( {{{7.5}^0}} \right)}}\)
4
cos (7.50)
