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.

摘要： A tire defect tester and a method of operation are disclosed. In one aspect, the tire defect tester includes a first electrode arranged to direct energy toward a tire, and a second electrode arranged on an opposite side of the tire from the first electrode to receive energy passing through the tire from the first electrode. The tire defect tester further includes an energy sensor electrically connected to the second electrode and a fault indicator circuit responsive to the energy sensor and configured to indicate the presence of a flaw upon energy above a threshold level being sensed at the second electrode.
