Below with reference to accompanying drawing and combine embodiment to specify the utility model.
The utility model provides a kind of permanent magnetism assist in synchronization reluctance motor; Comprise stator 30 and the rotor 20 that is arranged in the stator 30; Rotor 20 comprises rotor core 50 and the permanent magnet 40 of being located at 50 inside unshakable in one's determination; Its circumferential direction of rotor core 50 upper edges is provided with many group mounting grooves 10, and every group of mounting groove 10 comprises two or more mounting grooves 10 that is provided with at interval in the radial direction in rotor core 50; Permanent magnet 40 is many groups, and each permanent magnet 40 in every group of permanent magnet 40 embeds in the mounting groove 10 accordingly; Have between the two ends of the two ends of each permanent magnet 40 and the mounting groove of its embedding 10 at interval; The external diameter of rotor is D1, and the external diameter of stator 30 is D2, wherein, and D1/D2 >=0.55.
First embodiment with permanent magnetism assist in synchronization reluctance motor shown in Figure 3 describes; Its rotor 20 comprises the rotor core 50 of being processed by high permeability material or silicon steel sheet and places the permanent magnet 40 of rotor core 50; Six groups of magnetic pole units are distributing in the iron core 50 wherein; All magnetic pole units are arranged in the form that the N utmost point and the S utmost point replace in the rotor circumference direction; Each magnetic pole unit is by two-layer mounting groove 10 and place the permanent magnets 40 in the mounting groove 10 to form, and in mounting groove 10, puts into permanent magnet 40, requires same group of interior permanent magnet 40 to be same polarity towards the rotor peripheral direction during placement; Require two groups of adjacent magnetic opposite simultaneously, four groups of permanent magnets externally along the circumferential direction alternately distribute according to the NS utmost point.The radial direction ecto-entad of two-layer mounting groove 10 relative rotor centers is confirmed as outer mounting groove 10a and internal layer mounting groove 10b respectively, and correspondingly permanent magnet 40 is divided into outer permanent magnet 40a and internal layer permanent magnet 40b.Mounting groove 10 shown in Fig. 3 is an arc, and permanent magnet 40a and 40b are respectively an integral body, form arc in shape, and the end of this two permanent magnet 40 keeps certain distance with mounting groove 10 with layer respectively.
Because the stator outer diameter D2 to permanent magnetism assist in synchronization reluctance motor under some occasions has restriction; Through emulation and verification experimental verification; As shown in Figure 6, keeping under the constant situation of permanent magnetism assist in synchronization reluctance motor stator outer diameter D2 and permanent magnet use amount, the inductance parameters of permanent magnetism assist in synchronization reluctance motor changes along with the change of rotor diameter D1; Promptly along with the increase of rotor diameter D1; The d of permanent magnetism assist in synchronization reluctance motor, q axle inductance all increase to some extent, and the increase of q axle inductance is more obvious, make permanent magnetism assist in synchronization reluctance motor q, d axle inductance difference increase; Therefore permanent magnetism assist in synchronization reluctance motor has the ability of the bigger reluctance torque of generation; Improved the reluctance torque utilance, made the anti-demagnetization capability of permanent magnetism assist in synchronization reluctance motor strengthen greatly, thereby improved permanent magnetism assist in synchronization reluctance motor efficient and prolonged useful life.As shown in Figure 6, when D1/D2 >=0.55, can significantly improve permanent magnetism assist in synchronization reluctance motor q, d axle difference in inductance, make permanent magnetism assist in synchronization reluctance motor efficient improve.Preferably, D1/D2≤0.65.
When increasing permanent magnetism assist in synchronization magnetic resistance motor rotor external diameter; Combine the magnet structure design of multilayer again; Can make the q axle inductance of permanent magnetism assist in synchronization reluctance motor increase rapidly; Thereby increase q, the d axle difference in inductance of permanent magnetism assist in synchronization reluctance motor as much as possible, improve the utilance of permanent magnetism assist in synchronization reluctance motor reluctance torque further.
According to permanent magnetism assist in synchronization reluctance motor electromagnetic torque formula; The reluctance torque that increases permanent magnetism assist in synchronization reluctance motor need increase the q of permanent magnetism assist in synchronization reluctance motor, d axle inductance difference; And because under the situation of certain permanent magnet use amount; The d axle inductance of permanent magnetism assist in synchronization reluctance motor is difficult to big variation physically; Therefore can only increase q, the d axle difference in inductance of permanent magnetism assist in synchronization reluctance motor through the q axle inductance that increases permanent magnetism assist in synchronization reluctance motor, thereby improve the ability that permanent magnetism assist in synchronization reluctance motor produces reluctance torque.Fig. 7 is the number of plies of permanent magnetism assist in synchronization magnetic resistance motor rotor mounting groove 10 and the emulated data of the relation between inductance parameters; As shown in Figure 7; Keeping under the certain thickness situation of permanent magnet, changing what of permanent magnetism assist in synchronization magnetic resistance motor rotor mounting groove 10 numbers of plies, the d axle variation inductance of permanent magnetism assist in synchronization reluctance motor is very little; And q axle inductance has the sudden change of individual matter between one deck and multilayer; Promptly when the permanent magnetism assist in synchronization reluctance motor number of plies during greater than one deck, the q axle inductance of permanent magnetism assist in synchronization reluctance motor sharply increases, this mainly be because with one deck mounting groove structure in q axle magnetic flux mainly outer through different from permanent magnet; In two-layer or multilayer mounting groove structure; Q axle magnetic flux causes producing bigger q axle inductance more via the magnetic conduction channel flow mistake of 10 of two-layer mounting grooves, thereby has increased the ability of permanent magnetism assist in synchronization reluctance motor generation reluctance torque.From Fig. 7, also can find out, when the layer data of mounting groove 10 need be increased to 3 or more for a long time, Lq has increase slightly, so obvious not as there is one deck to become when two-layer the increase of q axle inductance when the number of plies in other words.On the other hand, in conjunction with the difficulty of manufacture craft, so the two-layer mounting groove rotor structure of optimal selection in the utility model.
In order further to improve permanent magnetism assist in synchronization reluctance motor efficient; Among first embodiment of the utility model, through increasing the height H 1 and stator ratio along height H axis direction on 2 of rotor, except much more more utilizing the permanent-magnet torque of permanent magnetism assist in synchronization reluctance motor along axis direction; Can also increase the reluctance torque of permanent magnetism assist in synchronization reluctance motor; Permanent magnetism assist in synchronization magnetic resistance motor rotor height H 1 shown in Fig. 8 has just been verified this point with the ratio of stator height H 2 to the influence of permanent magnetism assist in synchronization reluctance motor permanent magnetism magnetic linkage and inductance parameters well, from Fig. 8, can find out, along with the increase of rotor height H1; Permanent magnetism magnetic linkage and permanent magnetism assist in synchronization reluctance motor q axle inductance increase to some extent; But the d axle inductance of permanent magnetism assist in synchronization reluctance motor remains unchanged basically, reaches 1.3 when above when rotor height H1 increases to stator height H 2 ratios, and q axle inductance and magnetic linkage all increase very slow; When this ratio met or exceeded 1.4, q axle inductance and magnetic linkage were constant basically.Therefore, in the present embodiment, 1≤H1/H2≤1.4.
In addition; Has gap g in the radial direction at stator 30 between rotor 20 and the stator 30; This gap g generally also is called as permanent magnetism assist in synchronization reluctance motor width of air gap, and it is favourable to improving permanent magnetism assist in synchronization reluctance motor permanent-magnet torque to reduce permanent magnetism assist in synchronization reluctance motor width of air gap g.Permanent magnetism assist type synchronous reluctance permanent magnetism assist in synchronization reluctance motor for the utility model; Reduce permanent magnetism assist in synchronization reluctance motor width of air gap g except increasing permanent magnetism assist in synchronization reluctance motor permanent-magnet torque; Can also improve the reluctance torque of permanent magnetism assist in synchronization reluctance motor effectively; Thereby promote the efficient of permanent magnetism assist in synchronization reluctance motor further; This built-in type permanent-magnet synchronous permanent-magnet assist in synchronization reluctance motor with the low magnetic property ferrite permanent magnet of available technology adopting is compared, and performance advantage is more obvious.In first embodiment, 0.3mm≤g≤0.45mm.The width of air gap g of permanent magnetism assist in synchronization reluctance motor is to the influence of inductance parameters among first embodiment of Fig. 3 shown in Fig. 9; From Fig. 9, can find out; Under the situation that permanent magnetism assist in synchronization reluctance motor width of air gap g reduces gradually, the d axle inductance of permanent magnetism assist in synchronization reluctance motor slightly descends, but the increase of q axle inductance increases sharply; Particularly be reduced to 0.5mm when following when width of air gap; The increase of q axle inductance is more obvious, and this is highly beneficial to improving permanent magnetism assist in synchronization reluctance motor reluctance torque, however; Consider that permanent magnetism assist in synchronization reluctance motor under the small air gap width makes the difficulty with assembly technology, the width of air gap of common permanent magnetism assist in synchronization reluctance motor is not less than 0.3mm.
As shown in Figure 4 is second embodiment of the utility model, as shown in Figure 4, and the stator 30 among this embodiment is identical with first embodiment, and difference only is rotor 20.Mounting groove 10 in this embodiment rotor unshakable in one's determination 50 is the U-shaped structure; The radial direction ecto-entad of its relative rotor center is confirmed as outer mounting groove 10a and internal layer mounting groove 10b respectively; Correspondingly permanent magnet 40 is divided into outer permanent magnet 40a and internal layer permanent magnet 40b; Permanent magnet 40a and 40b are rectangle, place the middle part of mounting groove 10, and mounting groove 10 ends of the end of 40a and 40b and same layer keep certain distance.Among this embodiment, adjacent outer mounting groove 10a and the middle ware of outer mounting groove 10b are apart from being W, and the width between its relative both ends is respectively Wa and Wb, wherein, and Wa＞W, Wb＞W.The both ends Wa of ectonexine mounting groove 10 spacings and Wb width are greater than middle part spacing W; This makes the q axle magnetic flux at rotor 20 peripheral edge portions can get into rotor 20 more smoothly; Avoid mounting groove 10 ends to hinder the situation of q axle magnetic flux, in addition, do not place permanent magnet at the both ends of U-shaped mounting groove 10; This has also been avoided the permanent magnet end to be prone to the demagnetization and the undersaturated situation that magnetizes, and the anti-demagnetization capability of permanent magnetism assist in synchronization reluctance motor increases.
Fig. 5 is the 3rd embodiment of the utility model, and among this embodiment, the mounting groove 10 in the rotor 20 is a v-shaped structure, and the permanent magnet 40a of two rectangles and 40b place the two ends of V-arrangement mounting groove 10, and keeps certain spacing at the middle part of mounting groove 10.Among this embodiment; The two ends that permanent magnet 40a and 40b embedded V-arrangement mounting groove 10 respectively can be at the air gap flux density that keeps increasing effectively under the constant situation of permanent magnet 40 use amounts permanent magnetism assist in synchronization reluctance motor; Confirm according to emulation; Like Figure 10 and shown in Figure 11, under identical permanent magnet use amount, the air gap flux density of embodiment three increases nearly 50% than air gap flux density among the embodiment one; Increase closely 61% than air gap flux density among the embodiment two, this is to the permanent-magnet torque that increases permanent magnetism assist in synchronization reluctance motor and then to promote permanent magnetism assist in synchronization reluctance motor efficient highly beneficial.
Further, the permanent magnet that is provided with in the radial direction 40 numbers in rotor core 50 are less than or equal to mounting groove 10 numbers.As for fear of rotor outer layer permanent magnet demagnetization, the parameters such as back-emf and inductance that cause permanent magnetism assist in synchronization reluctance motor change and cause permanent magnetism assist in synchronization reluctance motor to drive reliability decrease, can not place permanent magnet in the outermost layer mounting groove 10a.
The utility model also provides a kind of compressor, comprises aforesaid permanent magnetism assist in synchronization reluctance motor.
According to above embodiment; Through adopting different mounting grooves and permanent magnet shape on the rotor structure and changing the position of permanent magnet in mounting groove; Can play different effects respectively; This is highly beneficial when the compressor seriation; Promptly can select different permanent magnetism assist in synchronization magnetic resistance motor rotor structures according to the watt level of compressor; With the technical problem that the compressor permanent magnet assist in synchronization reluctance motor that solves under the different capacity is difficult to break through, the not enough problem of the anti-demagnetization capability of low, the high-power compressor permanent magnet assist in synchronization of baby compressor permanent magnetism assist in synchronization reluctance motor efficient reluctance motor that particularly when the magnetic ferrites permanent magnet is hanged down in the employing of permanent magnetism assist in synchronization reluctance motor, is prone to.
