Abstract

<P>PROBLEM TO BE SOLVED: To solve the problem that power of a rotating magnet to resist the inverse direction is required, although the conventional generator applies lines of magnetic force at right angle direction with respect to a magneto coil and the magnetic force in the inverse direction is generated to the direction of rotation of the rotating magnet by the generated current. <P>SOLUTION: A change in the same magnetic field as a primary coil of a transformer is made by rotation of a rotating magnet 5. A generation receiving pole 4 facing the rotating magnet 5 is arranged over the whole circumference to prevent the action of magnetic force generated in the inverse rotation direction when the rotating magnet 5 is separated from the generation receiving pole 4. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

Detailed Description of the Invention

Industrial application fields

  Generator.

Problems to be solved by the invention

  The conventional generator applies a magnetic force line in a direction perpendicular to the power generation coil, and a magnetic force in the reverse rotation direction is generated with respect to the rotation direction of the rotating magnet (5) due to the generated current. The power of the rotating magnet (5) that opposes this reverse rotation direction is required.

Means for solving the problem

  The present invention performs the same magnetic field change as the primary coil of the transformer by the rotation of the rotating magnet (5), and arranges the power generation receiving electrode (4) facing the rotating magnet (5) over the entire circumference. The magnetic force in the reverse rotation direction that occurs when (5) leaves the power reception pole (4) does not act.

FIG. 1 shows an outline of a four-pole single-phase generator, and FIG. 2 shows an outline of a four-pole three-phase generator.
The shaft (1) bearing of the rotating magnet (5), the rotating means of the shaft (1), the fixing means of the iron core (2) of the magnetic circuit, the power receiving pole (4), the iron core of the magnetic circuit (2 1), the power generation coil of the coil iron core (3) is not shown in FIGS. 1 and 2, and the magnetic poles (4) are arranged over the entire circumference so that the magnetic leakage is minimized, so that the rotating magnet (5) is magnetic. Since the rotational force of the magnetic separation generated when leaving the receiving pole (4) is attracted to the next magnetic receiving pole (4), the rotating forces cancel each other as in the normal no-load operation of the generator.
For this reason, the shaft (1) of the rotating magnet (5) can be driven with a slight rotational force such as a bearing (not shown), the friction of the bearing of the driving means, and the windage loss of the rotating magnet (5). No limit.

The sine curve of the generated voltage and voltage control not shown are not considered.
In the case of voltage control, a separate coil is wound around the permanent magnet of the rotating magnet (5) to control the increase / decrease of the magnetism of the permanent magnet, and the generator voltage is rectified and a separate inverter is provided. Through this, a sine curve is obtained.

  The generator can be reduced in size by ignoring the mutual magnetic leakage of the magnetic poles (4) and disposing a small gap on the entire circumference of the same surface and arranging the magnetic poles (4).

The invention's effect

  The generator has the same characteristics as a transformer, and the power not shown in the rotating shaft (1) in Figs. 1 and 2 is arbitrary. It is done.

4-pole single-phase generator. 4-pole three-phase generator.
