Torque required to turn a self excited generator, Electrical Engineering

Assignment Help:

Work must be done against the electromagnetic torque in order to generate the voltage (and current) supplied to the electrical load connected to the generator. Therefore energy conversion occurs from mechanical energy to electrical energy.

The mechanical power input is T.ωThis is converted into electrical power e.Ia (Some may be lost due to friction and windage losses in a practical machine)

The electrical power out = Vout.Io

Vout is less than the induced emf 'e' due to volt drop across Ra and the brushes
