A power supply is a device that converts other forms of energy into electrical energy and provides the electrical energy to an electrical circuit (electronic device). The power supply referred to in this patent is a chargeable and dischargeable power supply.

A commutator is also called a "commutator". An important component on dc motors and ac commutator motor armatures. The armature winding element is made of a plurality of copper sheets separated by mica sheets, and each copper sheet is connected with some armature winding elements. When the armature rotates, the copper sheets are successively contacted with the fixed brushes. In a dc motor, ac power in an armature winding is converted into dc power between brushes by the brushes and a commutator. In an AC commutator motor, the frequency of the AC current between brushes is made to meet operating requirements. The commutator used in this patent mainly changes the direction of the current. In the rotor of the machine, the copper red portion is the true "commutator" which has many commutator poles. The commutator is rotated through an angle which changes the "tap position" from which the brushes draw current in/out. The rotor coil as a whole has a plurality of taps, and when the rotor coil rotates by one pole position, only part of the coil slot segments are subjected to current commutation, and most of the coil slot segments are not subjected to commutation.

The permanent magnet, i.e., the permanent magnet, may be a natural product, also called a natural magnet, or may be manufactured by man (the strongest magnet is a neodymium-iron-boron magnet). The material has wide magnetic hysteresis loop, high coercive force and high remanence, and can keep constant magnetism once magnetized. Also known as permanent magnetic material and hard magnetic material. In application, the permanent magnet works in a second quadrant demagnetization part of a magnetic return wire after deep magnetic saturation and magnetization. The permanent magnet should have as high coercive force Hc, remanence Br and maximum magnetic energy product (BH) m as possible to ensure storage of maximum magnetic energy and stable magnetism.

An electromagnet column, namely an electromagnet, is a device for generating electromagnetism by electrifying. The core is wound with an electrically conductive winding adapted to its power, and the coil, which is energized with electric current, is magnetic like a magnet, which is also called an electromagnet. It is usually made in the shape of a bar or shoe to make the core easier to magnetize. In addition, in order to immediately demagnetize the electromagnet when the electromagnet is powered off, the electromagnet is usually made of soft iron or silicon steel materials with fast demagnetization. When the electromagnet is electrified, the electromagnet has magnetism, and the magnetism disappears along with the electrification after the electromagnet is powered off. The electromagnet has wide application in daily life, and the power of the generator is greatly improved due to the utility model of the electromagnet.
