| Outline of Final Research Achievements |
For power transfer to the rotor circuit of excitation-type synchronous motors, we propose several contactless power transfer systems with different shape of pads and some resonant circuits to obtain the high efficiency of the power. We examine the characteristics of some contactless power transfer systems with different resonant capacitor topology to compensate for the leakage reactance and compared them. The rotating shaft of the rotor is covered with an aluminum sheet to reduce the loss due to the leakage flux. Power transfer tests were performed. A high efficiency of 91.8% was achieved when power was transferred to the rotor circuit of the synchronous motor.
