Front Pitch for DC Machine Calculator

Calculate Front Pitch for DC Machine ±5%

±5%



Formula

The formula to calculate the Front Pitch is:

\[ Y_F = \frac{(2 \cdot n_{slot})}{P} - 1 \]

Definition

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.

Example Calculation

Let's assume the following values:

Using the formula:

\[ Y_F = \frac{(2 \cdot 96)}{9} - 1 = 20.3333333333333 \]
