摘要
A brushless field exciter for wound synchronous machines that uses the resonance of the leakage inductance and a capacitor in a resonant field exciter to transfer energy to the rotating field winding. By resonating at frequencies greater than 50 kHz, this exciter reduces the overall size and weight of synchronous wound field motors at all power levels and extends the practical and economic power limits of synchronous wound field machines down to low integral and fractional HP applications, eliminating the permanent magnets now used in high efficiency motors and generators in that power range.
