Voltage-regulating of centrifugal permanent magnet generating set on farm vehicle

Abstract

Several couples of permanent magnet material are alternately fixed on the inside surface of the centrifugal rotor with nonmagnetic bolts. Adjoined permanent magnet material's polarity is opposite. And N poles and S poles are side by side. When the rotor turns, the magnet field turns and the set generates electricity. With the permanent magnet material of high remnant magnetic induction and the optimized design of the generating set, the output voltage is improved on the low rotate speed. A parallel regulator with the function of zero current blockades is designed. So the output voltage is stabilized when the rotate speed is high. It solves farm vehicle's problem of keeping the voltage steady on varied speed and load.
