JP2013085430A - Arrangement of coils in power generator - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a power generator comprising twice as many coils as permanent magnets among a power generator comprising permanent magnets and coils.SOLUTION: As schematically shown in figure 1, in contrast to a conventional power generator comprising permanent magnets and coils where a single pole of a permanent magnet acts on a coil to take out an induction current, a coil arrangement in a power generator of this invention has coils arranged at both poles of a permanent magnet to take out an induction current as output.

Description

  The present invention relates to a power generator using a permanent magnet and a coil, and using a number of coils that is twice the number of permanent magnets.

  In a generator using permanent magnets and coils, the number of permanent magnets and the number of coils are basically the same, and an induction current generated in the coils by the permanent magnets passing near the coils is taken out as a generator output.

  In a generator using permanent magnets and coils, the number of permanent magnets and the number of coils are based on the same number. The induced current generated in the coil is used as the generator output.

  By arranging coils twice as many as the number of permanent magnets, it is possible to extract an induced current from each coil, so that more output can be obtained than a generator using the same number of permanent magnets.

  An example of means for arranging coils that is twice the number of permanent magnets is shown in FIG. 1 as a conceptual diagram of a permanent magnet generator.

  Permanent magnets have N and S poles as the characteristics of the magnet. In a basic permanent magnet generator, the magnet poles are arranged in the same direction with respect to the coil, so the same coil is wound in the same direction. Polarity induced current is generated, and a single pole (N pole or S pole) of a permanent magnet is acted to obtain an induced current.

  FIG. 1 shows a conceptual diagram of an arrangement in which coils are arranged on both poles of a permanent magnet to obtain an induced current as a method for effectively acting on both poles (N pole or S pole) of the permanent magnet.

  In the arrangement shown in the conceptual diagram 1, the poles (N pole and S pole) of the permanent magnet 10 and the permanent magnet 11 are arranged to be the same pole with respect to the coil 1 a and the coil 2 a wound in the same direction.

  When the permanent magnet mounting bracket rotates to generate an induced current in the coil, an induced current is generated in the coil 1a, coil 1b, coil 2a, and coil 2b, and two coils (coil 1a, Coil 1b) The output was obtained.

  Although a permanent magnet generator using rare metal as a permanent magnet material has good power generation efficiency, there is a problem in cost. However, since a single permanent magnet can extract output from two coils, cost performance is improved.
