The formula to calculate the Front Pitch is:
\[ Y_F = \frac{(2 \cdot n_{slot})}{P} - 1 \]
Front Pitch is the distance between the two coil sides connected to the same commutator segment. Number of Slots depends on various factors such as the size of the generator, the type of winding used, the desired output voltage, and the power rating. Number of Poles refers to the total count of poles in an electrical machine for flux generation.
Let's assume the following values:
Using the formula:
\[ Y_F = \frac{(2 \cdot 96)}{9} - 1 = 20.3333333333333 \]
| Number of Slots (nslot) | Number of Poles (P) | Front Pitch (YF) |
|---|---|---|
| 90 | 9 | 19.000000000000000 |
| 92 | 9 | 19.444444444444443 |
| 94 | 9 | 19.888888888888889 |
| 96 | 9 | 20.333333333333332 |
| 98 | 9 | 20.777777777777779 |
