Questions and Answers

What is the definition of the Coil Span Factor $K_C$?

  • The difference between the voltages of two coil sides
  • The product of the voltages of two coil sides
  • The ratio of the voltage generated in the short pitch coil to the voltage generated in the full pitch coil (correct)
  • The sum of the voltages of two coil sides

    • What is the value of $K_C$ for a full pitch coil?

  • $0$
  • $1$ (correct)
  • $-1$
  • Depends on the value of $\alpha$

    • What is the value of $K_C$ for a short pitch coil?

  • Depends on the value of $\alpha$
  • Less than $1$ (correct)
  • Greater than $1$
  • Equal to $1$

    • What does the value $K_C = cos \dfrac{\alpha}{2}$ represent?
