Description
Technical field
The present invention relates to a kind of transverse flux permanent-magnet or reluctance permanent magnet motor, particularly a kind of transverse flux permanent-magnet or reluctance permanent magnet motor of ring body box structure.
Background technology
Transverse flux permanent magnetic motor is because its magnetic circuit & circuit is mutually vertical in space, overcome radial flux motors magnetic circuit & circuit, it is the shortcoming of size mutual restriction in same cylindrical cross-section of tooth and groove, there is the power of motor of raising and torque density, easily realize heterogeneous, the multipole feature to table structure, become the focus that motor technology circle is paid close attention to and studied.But, from the eighties in last century, since Germany professor H.Weh proposes transverse flux permanent magnetic motor (tranverse flux permanent magnet machine) conception, transverse flux permanent magnetic motor can not walked out laboratory, fails to occupy a tiny space on motor market, the world.
Find after deliberation, the technical problem underlying that hinders transverse flux permanent magnetic motor development is:
The first, in transverse flux motor stator and rotor, a series of iron cores that are circumference array distribution are discrete; Run through the winding of series of discrete slot for winding unshakable in one's determination, no matter have exoskeletally, all lack mechanical strength; , between stator core and winding thereof and rotor core and the permanent magnet comprising thereof or magnetic resistance permanent magnetic material laminated body, there is powerful electromagnetic force in the air gap both sides between stator and rotor, requires to have equal mechanical structure power balance with it.In the structural relation of stator and rotor, be a kind of natural selection take phase-phase stator or rotor as the basic element of character.Need to create a kind of mechanical structure mode, manufacture overall phase-phase stator or rotor parts, and should there is enough mechanical strengths.
The second, magnetic flux flow is to horizontal by radially changing into, and magnetic line of force place plane has turned 90 °, and this makes the original silicon steel sheets that always generally use in a large number in radial flux motors, is difficult to directly use in transverse flux motor.Silicon steel sheet has the characteristics such as gratifying low cost, low iron loss and the high permeability under high magnetic flux density (1.0～2.0T).These advantages of silicon steel sheet now any other motor ferromagnetic material do not have.In radial flux motors, silicon steel sheet is closed assembly vertically, and silicon steel sheet plane is that the sagittal plane at magnetic line of force place and the direction of rotation of motor are parallel.In transverse flux motor, need to create suitable manufacture method, manufacture transverse flux motor stator or rotor core take fairly simple process using silicon steel sheet as main material, and will make electrical steel plate plane is that magnetic line of force place plane is vertical with the direction of rotation of motor.
The 3rd, in radial flux induction machine, there is the winding overhang outside core slots in the front-end and back-end of stator or rotor, can produce leakage field and electromagnetic interference; In existing transverse flux motor, because the iron core of stator or rotor is all discrete, at discrete interval unshakable in one's determination, also there is the winding conductor being exposed to outside slot for winding unshakable in one's determination, can produce equally leakage field and electromagnetic interference.Need to be in the time of design transverse flux motor stator or rotor mechanical structure, consider discrete iron core and the winding conductor that is exposed to interval unshakable in one's determination to take electromagnetic shielding measure simultaneously.
The 4th, also have a special technical problem to need to solve for transverse flux permanent-magnet or reluctance permanent magnet motor: existing transverse flux permanent magnetic motor, in rotor air gap both sides, circumferencial direction, the permanent magnet polarity opposite direction of adjacent 2 rotor cores, only corresponding 1 stator core (quantity of phase rotor core is 2 times of phase stator core) in turn.If phase stator core with equate with phase rotor core number of pole-pairs, and corresponding one by one, will cause odd number stator core contrary with the flow direction in even number stator core, and the winding induced current that runs through odd number and even number stator coring groove is because opposite direction is mutually offset, this is unallowed.Therefore, the phase stator magnetic circuit of existing transverse flux permanent magnetic motor and circuit are in the utilance of circuferential spacing, and the utilance of phase rotor core and permanent magnet thereof all only has 50%.Need to create permanent magnet or magnetic resistance and the permanent magnetic material laminated body polar orientation of a kind of corresponding odd number and the rotor core of even number phase, switch the electromagnetic structure mode of corresponding odd number and even number phase stator core magnetic circuit and winding thereof, make the phase rotor core of each odd number of circumferencial direction air gap both sides or even number can a corresponding odd number or phase stator core magnetic circuit and the winding thereof of even number, make phase stator core and winding thereof the utilance for circuferential spacing, and permanent magnet in phase rotor core or the utilance of magnetic resistance and permanent magnetic material laminated body can reach due 100%.
The 5th, what transverse flux permanent-magnet and the difference of reluctance permanent magnet motor should only be to embed in its phase rotor core is permanent magnet or magnetic resistance and permanent magnetic material laminated body.
Be necessary to mention a patent of invention, patent application number: 201010100924.0, denomination of invention: flux switching type magnetic-concentration transverse flux permanent magnetic wind-driven generator.This invention is to make phase stator core and winding thereof reach due 100% for the utilance of circuferential spacing from existing 50%, the method of taking is that the permanent magnet embedding in a phase rotor core is changed into 2 of the relative left and right of polar orientation by 1, quantity has increased by 1 times, in these 2 permanent magnets in same rotor core, only have 1 to form magnetic loop with corresponding phase stator core in turn, another redundancy is had a rest, the utilance of the permanent magnet that phase rotor core embeds or with original, be 50%, but paid expensive cost price for this reason.From electromagnetic structure and mechanical structure angle, also there is open defect in this invention.First, for the transverse-magneticflux wind powered generator of the multipole logarithm by wind energy conversion system drives at a slow speed, radial dimension is more valuable than axial dimension, but this invention is in order to carry out magnetic flux switching, by the core section of phase stator from a side by turnover radially for laterally to centre, turnover, for radially inside, has increased the invalid radial dimension in phase stator core cross section again.Secondly, the phase stator winding of regular manufacture, although shortage mechanical strength, but its shape is rigidity, can not Free Transform, and also its width (from this inventive applicant specification accompanying drawing) should be greater than the throat width of stator coring groove, so, phase stator winding cannot be encased in a series of phase stator coring grooves at all, and more impossible while or priority, from the left side entrance of a phase stator coring groove, pack core slots into from the right entrance of another adjacent phase stator coring groove again.The core slots manual wire embedding's technique using in radial flux motors engineering is difficult to imitate in transverse flux motor engineering.The 3rd, how to be installed in motor housing or in rotating shaft about stator core, rotor core, this is an extremely important critical problem.But this invention inanition is claimed: it is characterized in that: rotor core is arranged on the cylinder (8) of non-magnet material, forms a rotor entirety; Stator core is arranged in the casing sleeve (7) of non-magnet material, forms a stator entirety.A bit known general knowledge has only been stated in this invention, does not but provide concrete technical scheme.
Summary of the invention
The technical problem to be solved in the present invention is:
Discrete according to transverse flux motor phase stator with phase rotor core, the phase winding that runs through discrete phase stator coring groove lacks the electromagnetic structure feature of mechanical strength, create a kind of mechanical structure mode, manufacture phase-phase stator or rotor parts entirety, that there is sufficient mechanical strength; Take silicon steel material as main, manufacture transverse flux motor phase-phase stator or rotor iron core with simple processing technology; Solve the electromagnetic shielding problem of phase stator and phase rotor part; Not increasing under the prerequisite of the permanent magnet that embeds in phase rotor core or magnetic resistance and permanent magnetic material laminated body quantity, create permanent magnet or magnetic resistance and permanent magnetic material laminated body polar orientation in a kind of corresponding odd number and the rotor core of even number phase, switch the electromagnetic structure mode of corresponding odd number and magnetic circuit and the winding thereof of the stator core of even number phase, make the utilance of the permanent magnet of phase rotor core or magnetic resistance and permanent magnetic material laminated body and phase stator core and winding thereof can reach due 100% for the utilance of circuferential spacing; What transverse flux permanent-magnet and the difference of reluctance permanent magnet motor were only to embed in its phase rotor core is permanent magnet or magnetic resistance and permanent magnetic material laminated body.

Remarkable advantage of the present invention and beneficial effect:
Motor is the entity of electromagnetic structure and mechanical structure.Structure problem is a first difficult problem that hinders transverse flux motor development.Because this difficult problem hinders, since German professor H.Weh proposes the conception of transverse flux permanent magnetic motor, transverse flux permanent magnetic motor fails to walk out laboratory, does not have bulk article to come out.
Ring body box structural approach has successfully solved the structure problem of transverse flux permanent-magnet or reluctance permanent magnet motor for the first time.Stator or rotor phase ring body box are manufactured by nonmagnetic steel material.Stator phase ring body is that phase stator core discrete 2 circumference array of odd number and even number and 2 1/2 phase windings and the locating ring thereof that run through U-shaped groove unshakable in one's determination are installed, are fixed in the concave-convex type structure in 3 part ring body boxes.Rotor phase ring body is by a rotor core that circumference array is discrete, comprise the permanent magnet or magnetic resistance and the permanent magnetic material laminated body that embed in iron core, also have nonmagnetic steel structure, and 2 road rotor core locating rings, install, be fixed in the concave-convex type structure in 2 part ring body boxes.In stator phase ring body box and rotor phase ring body box, electromagnetic structure, mechanical structure are conscientiously firm, are convenient to heat radiation, and ring body box mechanical strength can design as required.The global facility that stator phase ring body becomes closely separately with rotor phase ring body, accurate, mechanical strength is enough.
Stator phase ring body and rotor phase ring body separately inner circuit, magnetic circuit system are completely independent, except the 3 row magnetic pole end face unshakable in one's determination of both correspondences, all parts, comprise that iron core, winding, permanent magnet or magnetic resistance and permanent magnetic material laminated body, nonmagnetic steel structure, winding locating ring, rotor core locating ring are all completely enclosed within high magnetic resistance, high-resistance stator phase ring body box and rotor phase ring body box, can effectively reduce leakage field and humorous wave interference.Insulation vibration-absorptive material packing can be used in gap in phase ring body box between all electromagnetism parts and between electromagnetism parts and phase ring body box, strengthens the insulation property of electromagnetism part, reduces noise of motor.
Take ring body box assembling container as precondition, by U-shaped silicon steel sheet, along air gap stator side arc surface (utilizing special reliable mould), parallel stickup closed assembly, manufactures the iron core of stator phase ring body.Rotor phase ring body exterior cross-section unshakable in one's determination is E font, is divided into 2 kinds: for magneto, be made up of 4 parts: the L-R magnetic pole of connection, middle magnetic pole, permanent magnet, nonmagnetic steel structure; For reluctance permanent magnet motor, unshakable in one's determination formed by 3 parts: magnetic pole, nonmagnetic steel structure in magnetic pole or dextrad in the L-R magnetic pole of connection, left-hand.By the notch limit of the silicon steel sheet of the L-R magnetic pole of the connection through stamping-out, these 2 kinds of shapes of middle magnetic pole, along the parallel stickup closed assembly of air gap rotor-side arc surface (utilizing special reliable mould), silicon steel sheet plane is perpendicular to motor direction of rotation respectively.In permanent magnet, left-hand, in magnetic pole, dextrad, magnetic pole, nonmagnetic steel structure are special making in addition.Again with method assembling permanent magnet machine rotor iron core or reluctance permanent magnet motor rotor cores such as stickup, compactings.The manufacture method of stator and rotor phase ring body iron core is simple and practical, and material requested is: silicon steel sheet, permanent magnet or magnetic resistance and permanent magnetic material laminated body, nonmagnetic steel structure and insulating adhesive.
The iron core of stator phase ring body is divided into 2 circumference array in left and right by odd number or even number, and correspondingly, two 1/2 phase windings run through respectively the U-shaped groove of odd and even number circumference array iron core.Rotor phase ring body exterior cross-section unshakable in one's determination is E font, L-R magnetic pole is communicated with, take magneto as example, between a left side for odd number iron core, middle magnetic pole, embed permanent magnet, in, between right magnetic pole, embed nonmagnetic steel structure, in even number iron core, embed permanent magnet between right magnetic pole, between left, middle magnetic pole, embed nonmagnetic steel structure, vice versa; Odd number is identical with the polar orientation of permanent magnet in even number iron core.Rotor phase ring body rotor phase ring body unshakable in one's determination and magneto the structure unshakable in one's determination of reluctance permanent magnet motor is similar.Any moment of rotating at rotor, the magnetic flux flow of all stator phase ring bodies magnetic loop forming with rotor phase ring body iron core unshakable in one's determination is to consistent, suppose that (rotor core turns over a stator core) is counterclockwise during 0 °～180 ° electrical degrees, so, during 180 °～360 ° electrical degrees, (rotor core turns over another stator core) is exactly clockwise direction.Although this scheme has increased the axial dimension of stator phase ring body with rotor phase ring body, has saved more valuable motor radial dimension.The number of pole-pairs unshakable in one's determination of phase rotor ring body equals the number of pole-pairs unshakable in one's determination of phase stator ring body, the corresponding phase stator core of each phase rotor core.Phase stator core and winding thereof are increased to 100% for the utilance of circuferential spacing by existing 50%.The quantity of the permanent magnet embedding in phase rotor core or magnetic resistance and permanent magnetic material laminated body does not increase, and utilance is increased to 100% by existing 50%.
What transverse flux permanent-magnet and the difference of reluctance permanent magnet motor were only to embed in its rotor phase ring body iron core is permanent magnet or magnetic resistance and permanent magnetic material laminated body.
Radially synchronous reluctance magneto (Synchronous Reluctance Permanent Magnetic Motors) is the combination of reluctance-synchronous machine and permagnetic synchronous motor.Its advantage is: broad weak-magnetic speed-regulating range, good inverter utilance, high efficiency, and natural synchronizing characteristics.Transverse magnetic flux reluctance permanent magnet motor has been inherited the radially advantage of synchronous reluctance magneto, overcome again the structure limitation of radial flux reluctance permanent magnet motor, strengthen distinctive square high power being directly proportional and the high torque density to motor number of pole-pairs of transverse flux motor, and easily realize heterogeneous, multipole logarithm structural design, realize the feature directly driving.
Radiation air impeller is arranged in the rotating shaft at rotor phase ring body interval, good heat dissipation effect.
