Abstract

Description

  The present invention relates to a rotor of a transformer generator.

  Bicycle tire drive power ramp. Japanese Patent Application No. 2008-68500.

  In the conventional transformer-type generator, when the magnet is separated from the stator that receives magnetism in accordance with the eddy current of the stator and the rotation of the rotating magnet, a rotational resistance with a large magnetic attractive force is generated.

  The present invention reduces the number of occurrences of eddy currents in the stator of a transformer generator due to increase / decrease of magnetic field lines and changes in direction of magnetic field lines, and rotational resistance such as separation of the rotating magnet from the stator as much as possible. It is an object of the present invention to provide a generator that can be driven with a minimum rotational resistance, such as a bearing of a motor.

  The magnetic poles are rotated in the reverse rotation direction in the rotor so that the inner surface of the stator and the position of the rotor magnet are relatively the same, and the sliding action of the magnet with respect to the stator is prevented.

Hereinafter, embodiments of the present invention will be described with reference to FIGS.
1 to 3 show an 8-pole roll type single-phase generator. The rotating shaft 1 of the rotor made of a material that does not react to magnetism (non-metallic material) supported by the bearing 2 provided at the center of the cover 7 fixed to both ends of the outer cylinder 8, and fixed to the rotating shaft 1 A bearing 11 and the like are provided, and a permanent magnet four-pole rotating magnet 14 is provided between the bearings 11 diagonally.
The timing pulley 10 fixedly attached to the tip of the rotary shaft 9 fixed to the rotating magnet 14 and schematically shown is the same diameter as the double fixed timing pulley 4 fixedly attached to the cover 7 and schematically shown in FIG. When the rotary shaft 1 is rotated in a state where it is connected by the timing belt 15 schematically shown in FIG. 1, the rotary magnet 14 rotates at the same rotational speed in the reverse direction.

When the rotating shaft 1 of FIG. 2 is rotated by some means not shown, the rotating magnet 14 is separated from the stator 13 from which the power generation coil 18 shown in FIGS. 4 and 5 is omitted, and moves to the next stator 13. Further, since the outer periphery of the rotating magnet 14 is reduced in order to reduce the influence of each other's magnetism across the rotating shaft 1 of the rotating magnet 14, the difference between the revolution of the rotor and the rotation of the rotating magnet 14 is reduced. 2 slides about 30% in FIG. 2, but at this level, the rotational resistance of the rotor due to the eddy current of the stator 13 is slight.
Further, if the sliding action of the rotating magnet 14 is eliminated and smooth rotation is obtained and the diameter is increased, the rotating magnet 1 approaches the rotating shaft 1 and a separating action occurs due to the opposite magnetic forces, resulting in the rotational resistance of the rotor. Rotates smoothly.

Since there is no sliding action of the rotating magnet 14 in the stator 13, no eddy current is generated. Therefore, it is not necessary to use a conventional silicon steel plate including the iron core 12 of the magnetic circuit, and mild steel or the like may be used.
It is also possible to use the iron core 12 of the magnetic circuit as an outer cylinder 8 (not shown) made of mild steel and to fix the stator 13 made of mild steel or the like to the outer cylinder 8 with a screw.
The outer periphery of the rotating magnet 14 in FIG. 2 is a four-pole permanent magnet, which has a different polarity from the diagonal rotating magnet 14, and the magnetic force passes through the iron core 12 of the magnetic circuit so that the stator in FIGS. A voltage proportional to magnetism is generated in the power generation coil 18 shown in FIGS. 4 and 5, which is not shown in FIG.

As shown in FIG. 4, the generator coil 18 (not shown) of the diagonal stator 13 shown in FIG. 2 has the diagonal generator coils 18 wired in series to double the voltage, and this generates four sets sequentially in parallel. .
When these are connected in parallel, the current flows through the other power generating coils and is consumed, so only the power generating coil 18 generated as shown in FIG. 3 is connected, so that the power generated by the cam 3 fixed to the rotating shaft 1 is generated. When the position of the coil 18 is reached, the select switch 5 is provided at a position where the cam 3 is connected to the circuit, and the generator coil 18 is sequentially connected as the rotor rotates.

  FIG. 4 shows a circuit diagram of the select switch 5 and the power generation coil 18. Since the power generation coil 18 generates power only in an AC half cycle, a switch of a normal semiconductor (such as a thyristor) not shown is used because the switch time is 1/100 second in an extremely short time of 50 Hz.

  FIGS. 1 and 2 are single-phase generators. When three-phase power generation is performed with this, three identical generators (not shown) are provided, and the rotors are 120 degrees in electrical angle with each other (in the illustrated example, mechanical If the three rotation shafts 1 are directly connected with an offset of 30 degrees, a three-phase generator is obtained.

FIG. 5 shows means when the roll generator is a DC generator. A diode is used in place of the select switch 5 and four rectifier circuits are provided to provide a double-wave rectifier DC roll generator.
When this roll generator is a four-pole generator (not shown), the rotating magnet 14 becomes two poles (180 degrees), and magnetic separation occurs when moving to the next stator 13, which is the rotational resistance of the rotor. Become. On the contrary, if the number of poles is increased, the rotation is smoother, and the adjacent stator 13 generates power, which is convenient for DC power generation.

In FIG. 1 and FIG. 2, it is optional to provide a free roller made of mild steel or the like having the same length as the rotating magnet 14 (not shown) having the rotating shaft 1 as the rotating shaft on the rotating shaft 1 side of each rotating magnet 14.
If the outer diameter of the free roller has a slight gap with the rotating magnet 14, a complete series magnetic circuit (not shown) is formed, and the magnetic force of the permanent magnet is doubled and rotates in the same rotational direction as the rotating shaft 1. As a result, the power generation output is increased and the free roller is rotated by the magnetic force of the rotary magnet 14 so that the eddy current generated by the rotational resistance of the rotor is slightly generated.

Further, since it can be rotated with a weak rotational force and the rotational force and the power generation output are irrelevant, it is convenient for direct current power generation and it is not necessary to perform any control other than the dangerous rotation for centrifugal destruction.
For this reason, anything that can rotate the rotor can be used, driven by a part of the output power, river water currents, tidal current water turbines, anemometer wind turbines, etc. can also be used.

  The present invention does not take into consideration the rotor drive means, AC power generation voltage sine curve, voltage, frequency control, and the like. For this reason, in the case of parallel operation with other electric power, it is more convenient to perform DC power generation shown in FIG.

  The generator of the present invention has a variety of applications ranging from toys to spacecrafts and the like because the generator of the same nature as the transformer is optional and the drive means of the rotating shaft 1 in FIGS. 1 and 2 is arbitrary. Including homes, agriculture, industry, ships, automobiles, trains, aircraft, etc., including substitutes for oil, coal, combustible gas, nuclear power, etc. Contribute widely to the environment such as global warming.
