Abstract

PURPOSE: To obtain a method wherein electric energy is stored as the energy of rotational motion in a rotor of a motor having no mechanical rotating shaft, the motor is operated as a generator when need arises, and the energy of rotational motion of the rotor is converted into the electric energy and taken out. CONSTITUTION: (a) A magnet 2 is fixed to a rotor 1 corresponding to the rotor of a usual induction motor. (b) A magnet 4 is fixed to a lower fixing base 3 corresponding to a stator of the usual induction motor. (c) The magnets 2 and 4 are provided with polarities repelling each other by a magnetic force. (d) Around the rotor 1, a core 7 provided with a winding 6 is fixed to an upper fixing base 5, with a gap maintained between it and the rotor, like the stator of the usual induction motor. (e) The winding 6 is connected to an electric wire in the same way as in the usual induction motor and the electric wire is so provided as to be led outside.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention converts electric energy into rotational kinetic energy by the action of an electric motor and stores it in the rotor as rotational kinetic energy. It is a device to convert and take out.

[0002]

2. Description of the Related Art A conventional electric motor or generator has a rotating shaft connected to the outside, and the electric motor converts electric energy into rotational kinetic energy and takes it out through the rotating shaft. In addition, the generator converted the rotary kinetic energy input from the outside through the rotary shaft into electrical energy. Therefore, there was no concept of storing electrical energy as rotational kinetic energy in a rotor that does not have a mechanical axis of rotation and extracting it as electrical energy when needed.

[0003]

[Problems to be Solved by the Invention] In the industrial field,
The surplus electricity was used only for limited purposes, and was stored only as pumped-storage power generation or hot or cold water. The present invention makes it possible to store and release electric energy with minimum energy loss by storing the surplus electric power as rotational kinetic energy in a rotor having no mechanical rotation axis.

The structure will be described. (A) A magnet 2 is fixed to a rotor 1 corresponding to the rotor of a conventional induction motor. (B) The magnet 4 is fixed to the lower fixing base 3 corresponding to the stator of the conventional induction motor. (C) The magnets 2 and 4 are provided with polarities that repel each other due to magnetic force. (D) Like the stator of the conventional induction motor, the iron core 7 provided with the winding wire 6 on the upper fixed base 5 is fixed around the rotor 1 with a gap maintained between the iron core 7 and the rotor. (E) The winding 6 is connected to an electric wire as in the conventional induction motor, and the electric wire is provided so as to be taken out to the outside. The apparatus is operated as described above.

[0005]

ACTION AND EXAMPLE Next, the action and example of the present invention will be explained. Since the magnet 2 fixed to the rotor 1 and the magnet 4 fixed to the lower fixed base 3 are provided with polarities that repel each other's magnetic force, the rotor 1 and the magnet 4 provided on the lower fixed base 3 together with the magnet 2. Emerges and stabilizes. Further, since the upper fixed base 5 is provided with the iron core 7 provided with the winding wire 6, when the electric current is passed through the winding wire from the external power source, the rotor 1 and the magnet 2 are connected to the power source by the same principle as the induction motor. Rotates at a rotation speed proportional to the frequency. Next, when the rotor 1 and the magnet 2 are rotating and the current from the outside is stopped, a current is generated in the winding 6 according to the same principle as the induction generator. The winding 6 is connected by an electric wire to an external power source or a load. By this operation, electric energy is converted into rotational kinetic energy and stored.
Also, by this operation, rotational kinetic energy is converted into electric energy and taken out.

[0006]

The conventional electric power storage method is a very large-scale device as seen in pumped-storage power generation equipment, and in a small size, it is limited to a method of converting electric energy into hot water or cold water and storing it. According to the present invention, it is possible to store the surplus electric power and discharge the stored electric power when the electric power is insufficient, with a small loss, similarly to the pumped-storage power generation equipment, with this compact device.
