Description

Reduce the switched reluctance motor of noise and torque pulsation
Technical field
The utility model relates generally to a kind of switched reluctance motor, relates to a kind of reduction noise that constitutes with the switched reluctance motor of multilayer cascade and the switched reluctance motor of torque pulsation particularly.
Technical background
As known in the field, switched reluctance motor has that cost is low, efficient is high, starting torque is big, control is flexible and advantage such as simple, and vast potential for future development is arranged.But noise and vibration is comparison distinct issues of switched reluctance motor, thereby has limited its application in certain field.The radially magnetic pull that the magnetic pole of switched reluctance motor will be changed, thus stator core deformation and vibration caused, and this is the main cause that produces noise.The Another reason that switched reluctance motor produces noise is that torque pulsation torque in other words rises and falls.
Summary of the invention
The purpose of this utility model is the structure that proposes a kind of new switched reluctance motor, to reduce its noise and torque pulsation.
For this reason, the utility model proposes a kind of switched reluctance motor that constitutes by a plurality of single-phase switch reluctance motor of the coaxial arrangement of multilayer cascade, wherein, each of described switched reluctance motor layer is made of a single-phase switched reluctance motor, the switched reluctance motor of each layer separates installation in the axial direction successively between the upper and lower, all be installed on the same rotation axis rotor coaxial, the stator structure of each layer motor is all identical and arrange with one heart around each self-corresponding rotor, form very little air gap diametrically with corresponding rotor, the magnetic pole of the stator center line of the adjacent phase of described switched reluctance motor, the angle of cut that the rotor magnetic pole center line intersects concerns the number of phases/one rotor polar distance that spatially staggers mutually, thereby the single electric motor of a layer constitutes a phase of overall motor, the number of phases of described switched reluctance motor complete machine equal whole single electric motors and.So whole single electric motor forms switched reluctance motor integral body switched reluctance motor assembly in other words.Therefore, the stator magnet number of poles of the single switch reluctance motor of each layer is relatively few, and stator poles is apart from relatively big.The stator poles distance and the rotor polar distance of single electric motor are big, and effectively the angle of flow is also big.Because the number of phases of motor complete machine is many, desired step angle is relatively little, and each phase torque is with strong complementarity, helps reducing torque ripple.Because the effective angle of flow of single motor is big, the whole desired step angle of motor is little, closes the angle of rupture and reduces radially that magnetic pull reduces the noise leeway that stator core deformation causes so more have by dwindling than the switched reluctance motor of prior art.Simultaneously, the number of phases of single electric motor of the present utility model is few, help the magnetic magnetic pole of the stator of a phase make a pair of more than, the radial pull that dispersion rotor magnetic pole and magnetic pole of the stator produce during extremely to the utmost point reduces the vibration that stator core deformation causes.
A preferred implementation of the present utility model is a kind of threephase switch reluctance motor that is made of three single-phase switch reluctance motors of the coaxial arrangement of multilayer cascade, wherein, three single-phase switched reluctance motors separate installation in the axial direction successively between the upper and lower, all rotor is fixedly mounted on the same rotation axis with one heart, and the stator of whole single-phase motors forms very little air gap diametrically with corresponding rotor.The center line of the rotor magnetic pole of three single-phase switch reluctance motors motor axially on correspondingly alignment, and the center line of magnetic pole of the stator 1/3rd rotor polar distance that spatially stagger mutually, three single-phase switched reluctance motors are in conjunction with each phase that constitutes threephase switch reluctance motor complete machine.
Preferably, the single electric motor rotor number of poles of threephase switch reluctance motor described in the utility model is identical with stator poles, and is even numbers, for example the 4-4 utmost point, the 6-6 utmost point, the 8-8 utmost point, the 10-10 utmost point or more than.
The utility model is not limited to above explanation threephase switch reluctance motor, but can comprise the switched reluctance motor of any number of phases.
Therefore effective angle of flow of switched reluctance motor described in the utility model helps reducing torque ripple greater than effective angle of flow of the switched reluctance motor of prior art on year-on-year basis, also closes the angle of rupture and reduces vibrating noise sufficient leeway is provided for dwindling.And the radially magnetic pull circumference of described switched reluctance motor disperses on several magnetic pole of the stator, and the radially magnetic pull of conventional threephase switch reluctance motor is distributed on two relative on diameter magnetic pole of the stator.Therefore, the stator yoke deformation that switched reluctance motor described in the utility model all wants the radially magnetic drawing of ordinary tap reluctance motor to rise by the caused stator yoke deformation of magnetic pull radially is much smaller, that is to say can reduce because the noise that vibration causes highly beneficially.
An advantage of the present utility model is not increase the number of phases and only increase the step angle that stator magnet number of poles and rotor magnetic pole number just can dwindle complete machine, does not reduce motor basically simultaneously to exert oneself, and this helps reducing the torque ripple of low-speed running.Increasing stator poles can be dispersed in magnetic pull radially on the stator circumference further, is particularly conducive to the reduction vibrating noise.Similarly also can dwindle step angle by increasing the number of phases easily, improve the electromagnetism gearratio simultaneously.
Another advantage of the present utility model is to dwindle the step angle of whole phase by increasing the number of phases, and the increase of the number of phases that different with the ordinary tap reluctance motor is does not reduce effective angle of flow, and this helps reducing torque pulsation.
Another advantage of the present utility model is to accomplish the magnetic pole arrangement of short magnetic circuit easily.

Embodiment
Fig. 1 schematically illustrates the stator and the rotor relative position of the threephase switch reluctance motor of prior art.Fig. 1 represents a stator of a typical three-phase switched reluctance motor, the floor map of rotor, and the principle of a circuitry phase is shown.Six magnetic poles are arranged on the stator 101 of this switched reluctance motor, and each is wound with a coil on extremely, and the coil on the every pair of diametric(al) on the relative magnetic pole is correspondingly gone here and there (also) connection and connected, and forms a corresponding phase winding separately; Rotor 102 has four equally distributed rotor magnetic poles along circumference, does not have coil on the rotor magnetic pole; Between stator 101 and the rotor 102 very little air gap is arranged.Sa is the electronic switch of a phase, and E is a power supply.In the drawings with AA`, BB` and CC` refer to respectively A mutually, B mutually and C pole center mutually, and refer to two pole centers of pole center relative on two pairs of diameters of rotor respectively with 1-1` and 2-2`.And the stator winding of a phase only is shown, and electronic switch, power supply and winding connecting line are also only shown in Fig. 1 a.
Be briefly described the operation principle of prior art switched reluctance motor below with reference to Fig. 1 a to Fig. 1 c.For example in the position of Fig. 1 a, when the A of stator 101 phase pole center AA` does not overlap with the pole center 1-1` of rotor 102, when for example its angle of cut is 30 degree angles, switch S a closes, the energising of A phase winding, setting up in the motor with AA` is the magnetic field of axis, and magnetic flux is located closure through stator yoke, magnetic pole of the stator, air gap, rotor magnetic pole, rotor yoke etc.Magnetic resistance when the magnetic resistance of magnetic circuit is greater than the central lines of magnetic pole of the stator, rotor magnetic pole at this moment, so rotor 102 will be subjected to the torque that the tangential magnetic pull of the magnetic line of force crooked in the air gap produces, and rotor 102 is counterclockwise rotated.When last routine rotor 102 rotated 30 ° of angles, when AA` overlaps with 1-1`, the magnetic resistance minimum, rotor 102 reaches the equilbrium position, and promptly the stator 101 of A phase, rotor 102 are extremely to the utmost point, and at this moment tangential force disappears, shown in Fig. 1 b.By Fig. 1 b as seen, this moment, B phase magnetic pole of the stator center BB` was identical during just in time with the initial power-up of A phase with the relative position of rotor magnetic pole center line 2-2`.Carve at this moment and open A phase switch S and closed B phase switch not shown in the figures, setting up with BB` is the magnetic field of axis.Identical with above-mentioned principle, rotor 102 rotated counterclockwise when B switched on mutually, and when turning over 30 ° of angles, shown in Fig. 1 c, the center BB` of the magnetic pole of B phase stator 101 is relative with the pole center 2-2` of rotor 102.The rest may be inferred, switches on mutually to C when B cuts off the power supply mutually, and setting up with CC` is the magnetic field of axis.Turn over 30 ° of angles so again, when C cuts off the power supply mutually in the motor relative position of stator and rotor shown in Fig. 1 d, just the same with form shown in Fig. 1 a, only the relative rotor magnetic pole center line of stator A phase magnetic pole of the stator center line AA` is 2-2` rather than 1-1`.That is to say that rotor of A-B-C three-phase rotor winding wheel flow-thru electrode rotates counterclockwise 90 ° of rotor polar distance.Continuously press the order of A-B-C-A and give stator winding wheel flow-thru electrode respectively, rotor promptly rotates in the counterclockwise direction continuously.Give stator winding wheel flow-thru electrode respectively if continuously press the order of A-C-B-A, rotor promptly rotates along clockwise direction continuously.
From the above description as can be seen, when magnetic pole of the stator and rotor magnetic pole central lines, during just extremely to the utmost point, adjacent stator and rotor pole center line should the stagger angle of rotor polar distance/number of phases, just a step angle.Therefore, the stator magnet number of poles and the rotor magnetic pole number of prior art switched reluctance motor have certain relation, and for example, rotor magnetic pole is 4 o'clock, and the stator magnet number of poles is 6, and the rotor magnetic pole number is 6 o'clock, and the stator magnet number of poles is 8, and rotor number of poles and stator poles are unequal in a word.
Illustrate according to switched reluctance motor of the present utility model below with reference to a Fig. 2 and an a kind of execution mode shown in Figure 3 according to switched reluctance motor of the present utility model.
Fig. 2 is a half sectional view, and a kind of threephase switch reluctance motor according to three levels connection of the present utility model is shown.Fig. 3 schematically illustrates the stator and the rotor plane co-relation of each single-phase switched reluctance motor among Fig. 2, and the different angle position upper rotor part of rotor and the relative position between the stator are shown in Fig. 3 a-Fig. 3 d respectively.Switched reluctance motor shown in the figure comprises three single-phase switch reluctance motor A, B and C, and they have oneself stator 201 and rotor 202 separately.Wherein, three single-phase switched reluctance motor A, B and C separate installation in the axial direction successively between the upper and lower, and three rotors are fixedly mounted on the same rotation axis 208 with one heart, can synchronously rotate around the axis of public rotation axis 208.Referring to Fig. 3, stator 201a, the 201b of three single-phase motor A, B and C, the structure of 201c are identical, install around each self- corresponding rotor 202a, 202b and 202c, form very little air gap diametrically with corresponding rotor 202a, 202b and 202c.The pole center line radially of rotor 202a, the 202b of three single-phase switch reluctance motors and 202c aligns on the axial direction of motor, that is to say the rotor magnetic pole angle that spatially do not stagger.Rotor does not have coil.Stator 201a, 201b and 201c also respectively have four magnetic poles, and a coil 209 is all arranged on each magnetic pole.The pole center line of magnetic pole of the stator 201a, 201b and 201c motor axially on the projection 30 ° of angles of circumferentially staggering mutually.The stator coil string (also) of single stator 201a, 201b and 201c is associated in and constitutes A stator winding, B phase stator winding and C stator winding mutually mutually together respectively, and each is controlled with known mode in the field by electronic switch Sa, a Sb and Sc.Thereby constitute a motor assembly together by three motor A, B and C.Clear in order to show, exaggerated air gap among Fig. 3, simultaneously, electronic switch, power supply and winding connecting line are also only shown in Fig. 3 a.Omitted in the accompanying drawing for the inessential parts of explanation operation principle.
Below with reference to the operation principle of Fig. 3 a-Fig. 3 d explanation as the described switched reluctance motor of this execution mode.For the purpose of simplifying the description, the explanation of this paper based on each phase stator winding by 50% duty ratio making current.As shown in the figure, when position for example at Fig. 3 a, the pole center line of the stator 201a of A single-phase motor does not overlap with the pole center axis of rotor 202a, when for example its angle of cut as shown is miter angle, switch S a closes, A phase stator winding electrifying, setting up pole center line relative on the diameter with stator 201a in the motor is the magnetic field of axis, magnetic flux is located closure through stator yoke, magnetic pole of the stator, air gap, rotor magnetic pole, rotor yoke etc.Magnetic resistance when the magnetic resistance of magnetic circuit overlaps greater than stator 201a, rotor 202a pole center line at this moment, so rotor 202a will be subjected to the torque that the tangential magnetic pull of the magnetic line of force crooked in the air gap produces, and rotor 202a is counterclockwise rotated.When rotor 202a rotated 30 ° of angles, because rotor 202a, 202b and 202c are fixedly mounted on the same rotation axis coaxially, the magnetic pole of B phase stator 201b is identical when just in time beginning to switch on mutually with A with the relative position of the magnetic pole of rotor 202b, shown in Fig. 3 b.Carve the switch Sb of closed B phase stator 201b at this moment, set up in the B phase motor that relative pole center line is the magnetic field of axis on the diameter with B phase stator 201b, identical with above-mentioned principle, rotor 202b is subjected to the torque of the tangential magnetic pull generation of the magnetic line of force crooked in the air gap, rotor 202b is counterclockwise rotated, with A stator 201a torque phase superposition that rotor 202a is produced mutually.When this two-phase stator 201a, 201b switch on when making rotor turn over 15 ° of angles more jointly simultaneously, the pole center line of stator 201a and rotor magnetic pole central lines, at this moment magnetic resistance minimum, rotor 202a reaches the equilbrium position, be that A phase stator 201a and rotor 202a are during extremely to the utmost point, the tangential force of A phase motor contribution disappears, shown in Fig. 3 c.Carve at this moment and open A phase stator winding switch S a, make it rotor 102a not to be produced the braking square.The independent energising of B phase stator 201b turns over 15 ° of angles again, as Fig. 3 d as seen, this moment, the relative position of pole center line and the magnetic pole of rotor 202c of C phase stator 201c was just in time identical when beginning to switch on A, B phase winding, so closed C phase winding switch S c, the pole center line of setting up in the C phase motor with stator 201c is the magnetic field of axis.Switch on simultaneously when C, B phase winding and to make rotor turn over 15 ° of angles, then C phase winding when energising makes rotor turn over 15 ° of angle more separately, whole motor is promptly just the same with state shown in Fig. 3 a, and only the magnetic pole of the rotor 202a that the magnetic pole of A phase stator 201a is relative has turned over 90 ° of angles.That is to say that the once coaxial rotor of three phase winding A-B-C wheel flow-thru electrode rotates counterclockwise one 90 ° rotor polar distance.Continuously press the order of A-B-C-A and give each phase stator winding wheel flow-thru electrode respectively, coaxial rotor promptly rotates in the counterclockwise direction continuously.Give each phase stator winding wheel flow-thru electrode respectively if continuously press the order of A-C-B-A, rotor promptly rotates along clockwise direction continuously.
Coaxial mounted rotor 202a, the 202b of Fig. 2 and threephase switch reluctance motor shown in Figure 3 and the rotor polar distance of 202c have identical pole span with the rotor 102 of the switched reluctance motor of prior art three-phase 6-4 utmost point arrangement shown in Figure 1, therefore identical step angle is arranged, identical switching frequency is arranged under identical rotating speed.
Comparison diagram 1 and Fig. 3, the stator poles of motor shown in Figure 3 all is 90 ° of angles apart from identical with rotor polar distance, and the stator poles of switched reluctance motor shown in Figure 1 distance is 60 ° of angles.Satisfying under the condition of sufficient winding space, the maximum stator polar arc of Fig. 2 and switched reluctance motor shown in Figure 3 can reach 45 °, and the maximum stator polar arc of switched reluctance motor shown in Figure 1 is 30 ° of angles.Conducting side by side or the shutoff respectively of four stator coils of every phase winding of Fig. 2 and switched reluctance motor shown in Figure 3, and radially relative conducting simultaneously of two magnetic pole of the stator or the shutoff of the every phase of switched reluctance motor shown in Figure 1, so, under the thick identical condition of total stacked stator core, the total magnetic flux of the switched reluctance motor of present embodiment is not less than the switched reluctance motor total magnetic flux that the 6-4 utmost point is on year-on-year basis arranged during identical number of ampere turns.And because winding space is big, Fig. 2 and switched reluctance motor shown in Figure 3 can also improve number of ampere turns by increasing the number of turn.
Under the condition that only produces driving torque, effective angle of flow essence of the switched reluctance motor of Fig. 1 is about 30 °, and effective angle of flow of Fig. 2 and switched reluctance motor shown in Figure 3 almost can reach 45 °, and as mentioned above, both step angles are identical, all are 30 °.Therefore the utility model has improved repetition rate, helps reducing torque ripple.Also being not difficult to find out this operation principle from the front illustrates, is under 45 ° of conditions at the angle of flow, and A, B can reach 30 ° with the interior corner summation with the common conducting of other two-phase of the arbitrary turn-on cycle mutually of C.In other words, each phase torque is with strong complementarity.
In this article, " the effectively angle of flow " refers to such an extent that be, in the pass angle of rupture of switched reluctance motor under the prerequisite that only produces driving torque and the difference between the trigger angle.The stator magnet number of poles and the rotor magnetic pole number of ordinary tap reluctance motor as described above are unequal, therefore effectively the angle of flow must depend on stator poles apart from of rotor polar distance minimum, normally depend on the stator poles distance.And that each phase electromagnetic point of the utility model and mechanical angle stagger is irrelevant fully with the number of phases, and effectively the angle of flow has nothing to do with the irrelevant total even effectively angle of flow of the number of phases and number of magnetic poles, and the stator magnet number of poles equates with the rotor magnetic pole number.Be understood that the effective angle of flow of effective angle of flow of switched reluctance motor described in the utility model thus greater than the ordinary tap reluctance motor.
The difference of the angle of flow and step angle is big also for angle position control mode known in the field provides sufficient leeway, can more reasonably adopt control strategy known in the field.For example, known as those of ordinary skill in the field, suitably dwindle the pass angle of rupture and suitably turn-off reducing vibrating noise very useful in other words in advance.But, dwindle and close the angle of rupture and will be subjected to the restriction of aspect such as exert oneself of electric motor starting performance and motor.Be understood that from the above description switched reluctance motor of the present utility model dwindles and closes the angle of rupture and do not influence the leeway of the exerting oneself switched reluctance motor much larger than prior art.
In addition, Fig. 2 and every A of motor mutually, B of the execution mode shown in Figure 3 and radially magnetic pull of C is distributed on four magnetic pole of the stator circumferentially, and the radially magnetic pull of switched reluctance motor shown in Figure 1 is distributed on two relative on diameter magnetic pole of the stator.Therefore, the stator yoke deformation that the radially magnetic drawing of the switched reluctance motor of the deformation ratio 6-4 utmost point arrangement of the caused stator yoke of radially magnetic pull that Fig. 2 and switched reluctance motor stator shown in Figure 3 are subjected to rises is much smaller, that is to say in the time of can considerably reducing owing to switch motion because the noise that vibration causes.
Those of ordinary skill is appreciated that the stator magnet number of poles of single electric motor of each layer of threephase switch reluctance motor of above-mentioned execution mode is identical with the rotor magnetic pole number in the field, and can be arbitrarily, preferably even number.For example, when the low switching frequency of needs, also can be the arrangement of the 2-2 utmost point.The 6-6 utmost point, the 8-8 utmost point, the 10-10 utmost point or above arrangement can certainly be arranged.
The single switch reluctance motor that Fig. 4 illustrates a kind of each phase is rotor, the stator relative position schematic diagram of the single-phase switch reluctance motor of the embodiment that arranges of the 8-8 utmost point.Compare with the arrangement of the 4-4 utmost point, the step angle of 8-8 utmost point arrangement is reduced to 15 °, helps further reducing torque ripple.As can be seen from Figure 4, it all is the winding connection method of short magnetic circuit that the stator winding of the single phase of conducting simultaneously can have between adjacent pole, thereby can improve electromagnetic performance.The radially magnetic pull of embodiment shown in Figure 4 is dispersed on 4 pairs of magnetic pole of the stator circumferentially.Therefore further reduced the radially caused stator yoke deformation of magnetic pull.
Among the above embodiment, the rotor magnetic pole line of each layer single-phase motor spatially aligns, the number of phases/one the rotor polar distance and the stator magnet polar curve of adjacent phase spatially staggers.Certainly there is the stator magnet polar curve of each layer single-phase motor spatially to align, the execution mode of the number of phases/one rotor polar distance and the rotor magnetic pole line of adjacent phase spatially staggers, even the rotor magnetic pole line of adjacent phase and summation that the stator magnet polar curve spatially staggers are arranged is the execution mode of the number of phases/one rotor polar distance.
The threephase switch reluctance motor that is made of the coaxial arrangement of three single-phase motor multilayers cascade more than has been described, has certainly constituted the switched reluctance motor of the corresponding number of phases by the single-phase motor of any amount.
In the field those of ordinary skill as can be seen, the number of magnetic poles of switched reluctance motor of the present utility model and the number of phases are irrelevant, possess sizable flexibility, can satisfy various torque request and rotating speed requirement, therefore have wide practical use.
Be not difficult to find out, in above execution mode between phase and phase mutual inductance very little, so magnetic circuit is simple, can carry out independently that electromagnetism calculates to single monophase machine, has made things convenient for the magnetic structure optimal design.
The related control mode of the utility model is known in the field, because of not being illustrated than this paper.
Be to be understood that the above explanation of carrying out with reference to accompanying drawing is exemplary, and do not constitute that therefore, all fall into any modification of the defined spirit and scope of claims and become example and all should be encompassed in the utility model to restriction of the present utility model.
