Title: Permanent magnet generator
Inventor: TANAKA YASUHISA
IPC: H02N11/00
Filed: 2007-04-25
Abstract: <P>PROBLEM TO BE SOLVED: To provide a permanent magnet generator, capable of efficiently obtaining a large output by reducing combined inductance caused by self-induction and mutual induction of a coil.  <P>SOLUTION: When the magnetic flux of a permanent magnet 1 is changed by the magnetic flux of a magnetic flux control coil 2 to extract the output caused by electromagnetic induction from an output coil 3, inter-linking with the magnetic flux of the permanent magnet, two magnetic flux control coils are provided to flow the magnetic fluxes in a direction of canceling their magnetic fluxes with each other. Furthermore, the magnetic flux control coil is not interlinked with the magnetic flux of the permanent magnet to reduce the combined inductance due to the self-induction and the mutual induction, and a short magnetic path allows large magnetic flux to flow, even if the power supply is low in voltage and high in frequency, to control a big magnetic flux of a strong permanent magnet. Since two output coils are provided to allow the magnetic fluxes caused by a load current to flow in the direction to cancel with each other, the combined inductance due to self-induction and mutual induction is reduced, allowing a large current to flow, even by the increase in the output voltage attained by the increase in the number of winding of the output coil.  <P>COPYRIGHT: (C)2008,JPO&INPIT
