DC Generator Induced EMF Calculation

DC Generator Induced EMF Calculation

• The question asks for the induced EMF of a DC generator.
• The generator has 4 poles, 600 conductors, and a flux per pole of 0.064 Wb.
• The generator is lap wound and rotates at 1000 rpm.
• The formula for induced EMF in a DC generator is: E = (P * Φ * Z * N) / (60 * A), where:
  • E is the induced EMF
  • P is the number of poles
  • Φ is the flux per pole
  • Z is the number of conductors
  • N is the speed in rpm
  • A is the number of parallel paths
• For a lap winding, the number of parallel paths is equal to the number of poles (A = P).
• Substituting the given values into the formula: E = (4 * 0.064 * 600 * 1000) / (60 * 4) = 320V.
• Therefore, the induced EMF of the DC generator is 320V, and the correct answer is (B).
