• Alternators are the Power Generation Devices, converting mechanical energy into Electrical Energy, The electricity provided by our utilities is from some Power Generation center where an Heavy Alternator is the device producing Electricity .
  • Alternators have a design with wound rotor & wound stator; alternators available are with slip ring holders & also brushless types.
  • Students can make connections of their own with the help of the terminations provided for study of features viz. Single phase generation, 3Phase Generation, Regulation with change in Load, Effect of change of speed on output voltage, Effects of Field voltage excitation change.
