The energy storage technology is generally divided into thermal energy storage and electric energy storage, and the main energy storage applied to the global energy internet in the future is electric energy storage.

The energy storage technology is divided according to the technical principle and mainly comprises three categories of physical energy storage (such as water pumping energy storage, compressed air energy storage, flywheel energy storage and the like), chemical energy storage (such as lead storage batteries, flow batteries, sodium-sulfur batteries and lithium ion batteries) and electromagnetic energy storage (such as superconducting electromagnetic energy storage, super capacitor energy storage and the like).

Detailed Description

The present invention will be further described with reference to the following drawings and examples, and embodiments of the present invention include, but are not limited to, the following examples.

As shown in fig. 1 to 3, a power generation system based on an energy storage motor includes a magnetizing stator 1 capable of magnetizing and formed by processing a permanent magnet, a rotor 2 used in cooperation with the magnetizing stator 1 for storing electric quantity, and a permanent magnet generator 3 coaxially connected to the rotor 2 for delivering the stored electric quantity to the outside; the system also comprises a magnetizing machine and a magnetizing coil which is connected with the magnetizing machine, is wound on the permanent magnet stator 1 and realizes the magnetizing of the permanent magnet stator 1; the permanent magnet can realize circular magnetization, the number of the magnetizing stators 1 is two, the magnetizing stators are symmetrically distributed on two sides of the rotor 2, and the rotor 2 is made of electromagnet materials. And the utility model discloses a stator can adopt the electromagnet material, and the rotor can adopt the permanent magnet material, and the energy storage that can realize this application as long as the material of stator and rotor is permanent magnet and electromagnet respectively promptly.

In this embodiment, the stator is made of a circulating permanent magnet material, and the rotor is made of an electromagnetic material: the permanent magnet capable of circularly magnetizing is used for making a stator of a permanent magnet motor, an electromagnet is used for making a rotor of the motor, the principle is that the stator of the strong permanent magnet is used for driving the rotor of weak electromagnetism to drive a generator to generate electricity, and an electric brush connected with the rotor is contacted with different positive and negative electrodes during rotation (external power is needed in the initial operation stage, the external power is similar to a starting storage battery of an automobile, and the storage battery can be charged after the system is normally operated so as to ensure the continuous operation of the storage battery), so that the magnetic pole (N, S pole) on the rotor is periodically changed, the magnetic pole of the stator is attracted or repelled, and the rotor continuously rotates. One section of the rotor shaft is connected with a permanent magnet generator, and the generator is driven to operate when the rotor rotates, so that the purpose of generating electricity is achieved. The magnetic strength of the permanent magnet stator is far higher than that of the electromagnetic rotor, so that the external electricity can be used as little as possible during power generation. When the generator generates electricity, a small portion of the electricity can be used to power the rotor. The magnetic energy of the permanent magnet is consumed, the magnetic energy of the permanent magnet stator is reduced, the magnetizing coil of the magnetizing machine is integrated on the permanent magnet stator, and when the magnetic energy of the permanent magnet stator is reduced to a certain degree, the power generation is stopped. And magnetizing the permanent magnet stator by using a magnetizing machine to recover the magnetic energy of the permanent magnet stator. The circular work application, the magnetizing and the work application can play a role in magnetizing the electricity in the electricity consumption valley period particularly according to the electricity consumption conditions of the peak and the valley of the power grid so as to ensure the magnetic energy of the permanent magnet stator, generate electricity in the electricity consumption peak period and make up for the power supply deficiency of the power grid. Meanwhile, the magnetizing coil of the magnetizing machine is integrated on the stator of the permanent magnet motor, and the stator does not need to be detached during magnetizing, so that the magnetizing is convenient. It should be noted that the rotor does not exhibit magnetic poles at the position facing the permanent magnet stator, so that the rotor can rotate as long as the rotor is energized.

Specifically, in the present application, the change of the magnetism of the electromagnet on the rotor of the energy storage motor is explained from the first separation structure shown in fig. 2, the electromagnet on the rotor of the energy storage motor has three types of magnetism according to different connections with the positive electrode and the negative electrode of the input electricity, the S pole of the electromagnet (type 1) on the right side of the first rotor faces outwards, and the N pole faces inwards; the electromagnet (class 2) on the left of the second rotor has the N pole facing outwards and the S pole facing inwards; the third rotor up and down electromagnets (class 3) do not show polarity in this position; the electromagnets on the rotors are all provided with brushes, and when the brushes are in contact with the rotor power supply access distribution disc at different positions, different situations are generated on the magnetism of the two ends of the electromagnets, wherein the N pole faces outwards, or the S pole faces outwards. The electromagnets are not contacted with an external power supply at the upper and lower positions, and the two ends of the electromagnets do not show magnetism.

As shown in FIG. 3, when the S pole of the electromagnet at the right side of the electromagnet rotor shown in FIG. 3 faces outwards, the permanent magnet stators are attracted by the N pole of the lower permanent magnet stator; when the electromagnet N pole on the left side of the electromagnet rotor shown in fig. 3 is facing outward, it is repelled by the N pole of the lower permanent magnet stator; when the electromagnet rotor of the 3 rd class shown in fig. 3 does not exhibit magnetism, it is not affected by the magnetism of the lower permanent magnet stator; on the contrary, the action of the upper permanent magnet is opposite to that of the lower permanent magnet; under this condition, the electromagnet rotor all takes place clockwise rotation, and the energy storage motor begins work, and upper and lower permanent magnet stator is uncharged when this, and the electromagnet rotor is with external power source drive (similar car start storage battery) when starting, and the magnetism of rotor only need make clear the magnetism can, and power consumption is little. When the energy storage power generation system starts to generate power, the starting storage battery can be charged to maintain power supply and is connected to the electromagnet rotor to replace an external power supply.

The technology is that a stator of a strong permanent magnet is adopted to drive a rotor of weak electromagnetism to rotate so as to drive a generator to generate electricity, the magnetic energy of the permanent magnet can last for a long time, so that electricity can be generated continuously, after the magnetic energy of the stator permanent magnet is reduced, an energy storage motor can be stopped, and the stator permanent magnet is magnetized through a magnetizing system integrated on the stator. Therefore, a mode of cyclic power generation, magnetization and power regeneration is formed, and the permanent magnet motor has the energy storage effect.

The above-mentioned embodiment is only the preferred embodiment of the present invention, and is not a limitation to the protection scope of the present invention, but all the changes made by adopting the design principle of the present invention and performing non-creative work on this basis should belong to the protection scope of the present invention.
