1. What is Output Coefficient DC?

Output coefficient DC is a parameter used in electrical machine design that represents the substitution of equations of electric loading and magnetic loadings in the power equation. It is denoted by C₀ and provides a measure of the machine's output capability.

2. How Does the Calculator Work?

The calculator uses the Output Coefficient DC formula:

\[ C_0 = \frac{\pi^2 \times B_{av} \times q_{av}}{1000} \]

Where:

\( \pi \) — Archimedes' constant (approximately 3.1416)
\( B_{av} \) — Specific magnetic loading in Tesla
\( q_{av} \) — Specific electric loading in Ampere Conductor per Meter

Explanation: The formula combines the magnetic and electric loading parameters with the mathematical constant π to calculate the output coefficient for DC machines.

3. Importance of Output Coefficient DC

Details: The output coefficient is crucial in electrical machine design as it helps determine the machine's power output capability and efficiency. It provides a standardized way to compare different machine designs and optimize performance parameters.

4. Using the Calculator

Tips: Enter specific magnetic loading in Tesla and specific electric loading in Ampere Conductor per Meter. Both values must be positive numbers greater than zero for accurate calculation.
