Problems solved by technology

However, it is well known that when a magnetic force is generated between the permanent magnets, since the polarity of the magnetic poles is fixed, the direction of the magnetic force formed by the magnetic field is fixed, resulting in the magnetic effect of the permanent magnet stator on the permanent magnet rotor. The force cannot alternate between repulsion and attraction, and cannot produce the required, continuously oriented magnetic force to make the permanent magnet rotor rotate and output kinetic energy

Embodiment Construction

[0010] Two identical, each composed of two half-rings, whose magnetic poles are located on both sides of the end face, and half of the magnetic poles on the same side of the end face are S poles, and the other half is N poles. The side circular stator permanent magnets (4) and the rear circular stator permanent magnets (3) are concentrically arranged and fixed in the aluminum shell (14) of the motor, and the front circular stator permanent magnets and the rear circular stator permanent magnets Adjacent end face magnetic poles between the ring-shaped stator permanent magnets have the same polarity and the same semicircular angle position to repel each other. Two identical, each composed of two half-rings, whose magnetic poles are located on both sides of the end face, and half of the magnetic poles on the same side of the end face are S poles, and the other half is N poles. The side annular rotor permanent magnets (11) and the rear annular rotor permanent magnets (12) are fixed...

Abstract

The invention relates to a double-permanent magnet high-efficiency direct current power-saving motor. The motor transforms the magnetic permeability relationship of a permanent magnetic field throughan electromagnetic field, forms a magnetic troque output of the common magnetic acting force of a permanent magnet stator magnetic field and the electromagnetic field on a permanent magnet rotor magnetic field, more fully and effectively utilizes the inherent magnetic energy of the permanent magnet, enables the permanent magnet motor to further improve the energy efficiency and the power-saving rate to a greater extent, has the characteristics of high specific power, high rotating speed, no pulsation, small iron loss, small noise, simple structure and the like, and can be widely applied to thefields of energy conservation and environmental protection such as electric vehicles, household appliances, unmanned aerial vehicles and the like.

Description

technical field [0001] The invention relates to a power-saving motor in which the magnetic poles of the stator and the rotor are both permanent magnets. Background technique [0002] Rare earth permanent magnet motors are recognized as efficient and energy-saving motors. At present, the existing rare earth permanent magnet motor basically adopts the magnetic construction method that the variable electromagnetic pole magnetic field acts on the fixed permanent magnetic field: or the variable electromagnetic pole magnetic field of the stator acts on the permanent magnetic field of the rotor, or the variable electromagnetic pole magnetic field of the rotor acts on the stator The permanent magnetic field forms the directional rotation of the rotor and generates kinetic energy output under the interaction of the alternating magnetic force between the stator and the rotor. If the stator and rotor poles of the existing permanent magnet motor are all set as permanent magnets that ca...
