Abstract

The invention relates to a strong magnetic motor. Based on the common permanent magnet DC motor, a permanent magnet is thickened to become a cuboid or cylinder with a square section; and particularly when the ratio of the length A of the permanent magnet to the side length B of the section of the permanent magnet is 1.5:1, under the condition of not changing the area of the section, the magnetic field intensity of the acting surface of a magnetic field can be maximized. A rotor is a herical single-winding rotor, the number of turns of coils can be maximized, and the two opposite sides of the two permanent magnets are concave spherical surfaces adapted to the rotor, so the structure can make full use of the space between the two permanent magnets, maximize the length of conductors of the coils in a limited space, make more conductors in the limited space exposed in the magnetic field, and effectively improve the magnetic field intensity of the acting surface of the magnetic field of the rotor to increase the acting force between the rotor and a stator; therefore, due to the combination of the improvement in the two aspects, the constant permanent magnetic energy is transformed into mechanical energy, and the energy efficiency ratio of the motor is improved.

Description

A kind of strong magnetic motor

Technical field

The present invention relates to a kind of strong magnetic motor.

Background technology

Traditional permanent magnet direct current motor, general stator is the tile permanent magnet, because magnet thickness is thinner, its magnetic field intensity a little less than, the active force that produces with coil a little less than, when electric energy is converted into mechanical energy, its Energy Efficiency Ratio is lower, in today of world energy supplies anxiety, when electric energy is converted into mechanical energy, provide the more present beyond doubt problem that needs solution of dynamic power machine of high energy efficiency ratio.

Summary of the invention

Technical problem to be solved by this invention is to overcome the deficiency of above-mentioned prior art, and a kind of more strong magnetic motor of high energy efficiency ratio that has is provided.

According to strong magnetic motor provided by the invention, comprise stator, rotor, commutator, described stator is two relative permanent magnets of heteropole, described rotor is arranged between two permanent magnets, described permanent magnet is that the cross section is foursquare cuboid or cylinder, described rotor is spherical simplex winding rotor, described rotor comprises iron core and the coil that is wrapped on the iron core, described iron core comprises a cylinder and is arranged on the big end at cylinder two ends, described big end forms a spherical part, described coil is wrapped on the cylinder and is wound in spherical another part, the length A of described permanent magnet is 1.4 to 1.6: 1 with the ratio of the size of its cross section length of side or the B that directly plays, described rotor is arranged in the rotor case, both sides are respectively equipped with bolster and output shaft before and after the described rotor case, by the bearing supporting, two opposite faces of described two permanent magnets are the concave spherical surface that adapts with rotor respectively for described bolster and output shaft.

The present invention also has following additional technical feature:

Described bearing is a unilateral bearing.

The length A of described permanent magnet is 1.5: 1 with the ratio of the size of its cross section length of side or diameter B.

Compared with prior art have following advantage according to the present invention: the present invention is on the basis of common permanent magnet DC motor, thickness thickening with described permanent magnet, thickening into the cross section is foursquare cuboid or cylinder, the length A of described permanent magnet is 1.4 to 1.6: 1 with the ratio of the size of its cross section length of side B, particularly the length A of described permanent magnet is 1.5: 1 o'clock with the ratio of the size of its cross section length of side B, under the constant situation of permanent magnet sectional area, can increase the magnetic field intensity of the action of a magnetic field face to greatest extent, simultaneously rotor is made spherical simplex winding rotor, can increase the number of turn of coil to greatest extent, two opposite faces of described two permanent magnets are the concave spherical surface that adapts with rotor, this structure can make full use of the space between two permanent magnets, in the confined space, increase the length of coil-conductor to greatest extent, make that more conductor is exposed in the magnetic field in the confined space, increased the magnetic field intensity of rotor field acting surface effectively, thereby increased the active force between rotor and the stator, therefore the improved combination in above-mentioned two places, can change constant permanent magnetism into mechanical energy, improved the Energy Efficiency Ratio of permanent magnet DC motor greatly, it is very energy-conservation.
