U-shaped electronically controlled magnetic motor

Abstract

The invention relates to a U-shaped electronic control magnetic motor belonging to the field of permanent magnet energy development. The U-shaped electronic control magnetic motor mainly consists of a permeability magnetic material case, a front end cover, a rear end cover, a main shaft, a position detection circuit board, a shielding plate, a U-shaped stator, a salient pole type rotor, a bearing, an inner bearing pressure cover and an outer bearing pressure cover, wherein the U-shaped stator consists of a permeability magnetic material, an electromagnetic coil and a permanent magnet; a stator core and an inner circle wall of the case are connected by bolts; the salient pole type rotor is in keying connection with the main shaft; and a trough-type optocoupler of the sensor is mounted on the position detection circuit board on the outer side of the rear end cover of the main shaft. According to a three-phase winding, the stator coil is controlled by a controller and acts on the permeability magnetic salient pole to drive the rotor to rotate, so that the permanent magnet energy can be effectively converted with less power consumption.

Description

technical field [0001] The invention belongs to the field of permanent magnet energy development, and in particular relates to a U-shaped electronically controlled magnetic motor utilizing permanent magnet energy. Background technique [0002] Petroleum, coal and other fossil mineral fuels provide 91% of the world's primary commodity energy, of which coal accounts for 28% and oil accounts for 40%. However, the reserves of fossil fuels on the earth are limited. It is rapidly becoming exhausted. According to statistics, human beings burn 4 billion tons of coal and 2.5 billion tons of oil every year; and it is growing at a rate of 3% per year. If this continues, scientists estimate that the coal on the earth can still maintain two to three hundred years, and oil is only used for 50 to 60 years, and the excessive development and unrestricted consumption of these fossil energy sources have also brought about extremely serious negative effects, such as inducing the global greenhou...

[0002] Petroleum, coal and other fossil mineral fuels provide 91% of the world's primary commodity energy, of which coal accounts for 28% and oil accounts for 40%. However, the reserves of fossil fuels on the earth are limited. It is rapidly becoming exhausted. According to statistics, human beings burn 4 billion tons of coal and 2.5 billion tons of oil every year; and it is growing at a rate of 3% per year. If this continues, scientists estimate that the coal on the earth can still maintain two to three hundred years, and oil is only used for 50 to 60 years, and the excessive development and unrestricted consumption of these fossil energy sources have also brought about extremely serious negative effects, such as inducing the global greenhouse effect, smog, and drought A series of problems such as floods, acid rain, etc. have greatly polluted the environment on which human beings depend. Therefore, finding new alternative energy sources and solving the future energy demand of the world has become a top priority for human society.

[0003] At present, human beings pin their hopes of replacing fossil energy on the development of solar energy, nuclear energy and hydrogen energy, and use wind energy, biomass energy, ocean energy and other new energy sources as partial supplements, but people ignore a better, potential and huge And high-density energy, that is permanent magnet energy. Although people have realized that there is a strong potential energy in the permanent magnet itself, and it has been well used in the permanent magnet motor, but the permanent magnet energy is used as a new energy source for research and development. It has not attracted enough attention in the world. The annual output of NdFeB in the world can reach 150,000 tons. The annual output of ferrite is abundant, which can meet the needs of permanent magnetic energy conversion equipment. Permanent magnets can be used for repeated magnetization. Magnetic energy has the primary favorable conditions to replace the huge fossil energy. The current main task is to find out the method and scientific design scheme of using permanent magnetic energy
