Abstract

The double excited induction motor has two sets of three-phase system : One is connected to the ac source to take care of energy convertion, and the other is to the inverter controlable frequency and/or magnitude of voltage, both of the induction mode and the synchronous mode are possible in double excitation motor, and the proposed double excitation motor can be driven as a synchronous motor by the extra three-phase input. At the synchronous mode the efficiency is improved so higher than that at induction mode or induction motor. The rating of the inverter used for speed control can be reduced upto one-fifth of that for conventional induction motor. Also the cost and maintenance fee of double excitation induction motor can be reduced compared to any other motors.
