Summary of the invention
The technical problem solved
Magnetite magnetic force is utilized to replace the power-electromagnetic force of the cutting magnetic line in motor.Magnetite magnetic force is applied, simultaneously also application of suction repulsion between the stators and rotators of motor.
Basic technical scheme
The magnetite of two same shapes, provides magnetic field, its magnetic pole area, and magnetic field intensity is identical, and two N pole (or S pole) is relative; The 3rd magnetite is put in the centre of two N pole field, N pole and the S pole interconnector of the 3rd magnetite are called magnetite field axis, the field axis direction of the 3rd magnetite becomes 90 degree ± 45 degree with the direction of two N pole fields, two identical magnetites are motionless, 3rd magnetite to the N extreme direction campaign in its field axis direction, namely field axis presses N pole in the extremely posterior motion of front S.Its power is magnetite magnetic force.Only admit to there is suction repulsion, do not admit a lot of expert professors of the existing theory of existence the 3rd power-magnetite magnetic force, when answering the direction of motion of above-mentioned 3rd magnetite, owing to only admitting to there is suction repulsion, 3rd magnetite is to the S extreme direction campaign in its field axis direction, and namely field axis presses S pole in the extremely posterior motion of front N.But in above-mentioned actual experiment, the 3rd magnetite to the N extreme direction campaign in its field axis direction, namely field axis presses N pole in the extremely posterior motion of front S; Not the S extreme direction campaign of the 3rd magnetite to its field axis direction, namely field axis presses S pole in the extremely posterior motion of front N.Existing theory can not be correct the newfound original invention of explanation.
When two identical magnetites become a magnetite, 1st magnetite provides magnetic field N pole (or S pole), the magnetic field N that 2nd magnetite provides at first magnetite extremely in, the field axis direction of the 2nd magnetite becomes 90 degree ± 45 degree with the direction of the N pole field of the 1st magnetite.1st magnetite is motionless, and the 2nd magnetite is subject to two power.A power is magnetite magnetic force, and its Producing reason is that the field axis direction of the 2nd magnetite becomes 90 degree ± 45 degree with the direction of the N pole field of the 1st magnetite.A power is also had to be making a concerted effort of suction repulsion, because the field axis direction of the 2nd magnetite becomes 90 degree ± 45 degree with the direction of the N pole field of the 1st magnetite, only has the N pole field of the 1st magnetite, so the N pole of the S pole of the 2nd magnetite and the 1st magnetite produces suction, the N pole of the 2nd magnetite and the 1st magnetite N pole produce repulsion, the power of making a concerted effort the 2nd magnetite to be subject in the direction of the clock or counterclockwise to rotate of suction repulsion.When providing, the 2nd of field axis direction the magnetite is motionless, and provide the 1st the magnetite motion in magnetic field, then the 1st magnetite be not by suction repulsion.
Space between two the adjacent magnetites providing magnetic field N pole (or S pole) on a plane, puts the magnetite that provides field axis N-S.Produce suction repulsion between the magnetite providing field axis N-S and provide magnetic field two adjacent magnetites, the S side providing the magnetite of field axis N-S is suction, and N side is repulsion simultaneously.The direction of its suction repulsion is identical.The magnetic field provided is constant, and the field axis provided becomes S-N pole by N-S pole, then the direction of suction repulsion changes 180 degree.
More than provide the magnetite of field axis to change solenoid into, solenoid is fixed on motor stator, provides field axis N-S pole after solenoid energising.The magnetite in magnetic field is more than provided, is fixed on rotor, provides magnetic field, rotate.Solenoid replaces providing it produces after the magnetite of field axis magnetite magnetic force, suction repulsion effect the same.
Utilize the embodiment of basic technical scheme
Embodiment 1 stator last layer solenoid, the magnetite magnetic force brshless DC motor of rotor last layer magnetite
Epitrochanterian magnetite adopts arc-shaped, and generally its angle is more than 90 to spend, and also can be 120 degree, also can angle less.Its magnetic pole provided can for upper and lower magnetic field, also can be inside and outside magnetic field.Its angle be more than 90 degree or 120 degree time, epitrochanterian one deck magnetite only uses magnetite 1 and magnetite 2 two, and two magnetites are uniform, and the space angle between magnetite is also equal.When the angle of arc-shaped magnetite is less, select suitable number, make the angle of magnetite equal with the space angle between magnetite.The magnetic field width that epitrochanterian magnetite provides will meet the needs of the magnetic coil poles axis N-S pole on stator.The magnetic field intensity that epitrochanterian magnetite provides confirms according to power.Below with only having two magnetites to be that example illustrates in one deck magnetite.
When rotor last layer magnetite only uses two magnetites, the number of the solenoid on stator is 4, and 4 solenoids can uniform (also can not be uniform) in same plane.The position that solenoid 1 is identical in the magnetic field of epitrochanterian two magnetites with solenoid 3, relative 180 degree; During energising, its field axis N-S pole makes epitrochanterian magnetite all be subject to the magnetite magnetic force of equidirectional.Solenoid 2 and solenoid 4 also relative 180 degree; Because the field axis N-S pole of solenoid 2 and solenoid 4 is extremely contrary with the field axis N-S of solenoid 1 and solenoid 3, i.e. S-N pole, makes epitrochanterian magnetite be subject to suction repulsion simultaneously, but suction repulsion direction is identical with the direction of magnetite magnetic force.The magnetite magnetic force that rotor is subject to, the direction of suction repulsion are identical, and magnetite magnetic force, suction repulsion make the same direction of rotor run well.
When on rotor, two magnetite magnetic fields enter the center of solenoid 2 and solenoid 4, solenoid 2 turns into N-S pole around with the field axis S-N pole of solenoid 4, and namely the both positive and negative polarity of the DC power supply of solenoid 2,4 turns around.So its magnetite magnetic force produced is identical with the magnetite magnetic force direction that solenoid 3 produces with solenoid 1.Equally, when the space on rotor between two magnetites enters the center of solenoid 1 and solenoid 3, solenoid 1 turns into S-N pole around with the field axis N-S of solenoid 3, and namely the both positive and negative polarity of the DC power supply of solenoid 1,3 turns around.So its suction repulsion produced is identical with the suction repulsion direction that solenoid 4 produces with solenoid 2.
When two magnetite magnetic fields on rotor are respectively at solenoid 1,2,3, be all subject to the magnetite magnetic force of equidirectional when 4;
When the space on rotor between two magnetites is respectively at solenoid 1,2,3, be all subject to the equidirectional suction repulsion with magnetite magnetic picture when 4.The both positive and negative polarity that DC power supply provides provides different both positive and negative polarities at diverse location.
DC power supply provides the different methods of both positive and negative polarity and the same of permanent-magnet brushless DC electric machine.Be grouped into by Hall element and power control part.Do not describe in detail.Just in time, when the nose motion in magnetite magnetic field on rotor is to shortly past solenoid 1, during the center of 2,3,4, provide positive pole-negative pole, generation magnetite magnetic force at once; When the rear end in magnetite magnetic field on rotor moves to and will leave solenoid 1,2,3, during the center of 4, power-off at once.Equally, when the nose motion in the space on rotor between two magnetites is to shortly past solenoid 1, during the center of 2,3,4, provide negative pole-positive pole at once, produce suction repulsion; When the space on rotor between two magnetites
Rear end move to and will leave solenoid 1,2,3, during the center of 4, power-off at once.Solenoid 1,2,3,4 short to the time compole of power supply from power-off, the time of about 95% powers and stressed.Because when the rear end in magnetite magnetic field on rotor moves to and will leave solenoid 1,2,3, during the center of 4, power-off at once, the front end in the space now on rotor between two magnetites moves to solenoid 1,2,3 at once, the center of 4, time compole short, power-off time is extremely short.If above structure only uses two solenoids, in epitrochanterian magnetite magnetic field, place powers, and the space place between two magnetites does not power; When space place between two magnetites does not power, the iron core in solenoid will be subject to the suction of epitrochanterian magnetite, and this suction will reduce power output, namely lower efficiency.In said structure, there is solenoid at the space place between two magnetites, makes the direction of suction repulsion identical with the direction of magnetite magnetic force, the effect just do not lowered efficiency.Axles etc. are the same with common electric machine.
Embodiment 2 stator last layer solenoid, the magnetite magnetic force brshless DC motor of two-layer magnetite on rotor
Rotor is established two-layer magnetite, two-layer magnetite one on the other, establishes two equally distributed magnetites for every layer, the dimension angle of two-layer 4 magnetites is equal, 4 magnetites are relative up and down, and the polarity between two-layer magnetite is all N pole or S pole, and one deck solenoid on stator is between the upper and lower two-layer magnetite of rotor.Other in the same manner as in Example 1.
Beneficial effect
Suffered by the motion of dynamic magnetite, power is magnetite magnetic force, suction, repulsion, is all the power produced between magnetite and solenoid.All solenoids are all powered in the time of about more than 95% and make rotor stressed, under identical power output, and the small volume of this equipment.This equipment is subject to suction repulsion in the space between two magnetic field, and its direction is identical with rotor motion direction; The have more than is needed suction repulsion of profit conduction time of all each solenoid of permanent-magnet brushless DC electric machine; It is when power-off, and all each solenoids are sharp have more than is needed suction repulsion also.Utilize magnetite magnetic force, suction, repulsion, this equipment improves than the efficiency of permanent-magnet brushless DC electric machine.There is energy-saving significance.
