Description
本發明係有關一種電機裝置,特別是有關於一種定子配置有電樞繞組及/或場繞組,定子與動子設有凸齒與槽部之磁通切換型電機裝置。 The present invention relates to a motor device, and more particularly to a flux switching type motor device in which a stator is provided with an armature winding and/or a field winding, and a stator and a mover are provided with a convex tooth and a groove portion.
電機裝置包含馬達與發電機,結構大致上皆包含定子及動子。一般永磁無刷馬達的永久磁鐵是位於動子上,但磁鐵亦可位於定子上,如美國專利第5672925號所揭露之磁通切換型永磁馬達。一般低速的馬達若動子採取多磁極的設計較容易得到大扭力的特性,然而受限於定子繞線及結構強度的要求,定子槽數與動子極數的設定有其物理上的限制。而多磁極的動子磁石的黏貼加工亦會造成問題,因此美國專利第4190779號、第4695777號、第4712028號揭露了不具有永久磁鐵的無刷馬達以達成多磁極的作法。又如美國專利第4757220號、第7064468號揭露了永磁無刷馬達以達成多磁極的作法。因此,如何有效率的產生多磁極的馬達架構,即成業界亟欲解決的問題。 The motor device includes a motor and a generator, and the structure generally includes a stator and a mover. Generally, the permanent magnet of the permanent magnet brushless motor is located on the mover, but the magnet can also be located on the stator, such as the magnetic flux switching type permanent magnet motor disclosed in U.S. Patent No. 5,672,925. Generally, a low-speed motor is more likely to obtain a large torque characteristic if the multi-pole is designed. However, due to the stator winding and structural strength requirements, the number of stator slots and the number of poles have physical limitations. The sticking process of the multi-pole pole magnets also causes problems. Therefore, U.S. Patent Nos. 4,190,779, 4,695,777, and 4,712,028 disclose a brushless motor having no permanent magnets to achieve a multi-pole. A permanent magnet brushless motor is disclosed in U.S. Patent Nos. 4,757,220 and 7,064,468 to achieve a multi-pole. Therefore, how to efficiently generate a multi-pole motor structure is an issue that the industry is eager to solve.

The motor device mainly includes a stator 11 and a mover 12, and the mover 12 is formed with n first equidistantly arranged first convex teeth 121 facing the stator 11, and each of the two first convex teeth 121 is spaced apart by a first groove portion 124. The stator 11 is formed with a plurality of grooves 115 facing the mover 12, and each of the grooves 115 is open to the end of the mover 12 with a second groove portion 117. The number of the grooves 115 is S, and the movement between each two grooves 115 is toward the mover. The third groove portion 119 is opened, and the armature winding 13 spanning the groove portion 115 is wound between the adjacent third groove portions 119. At least one second protruding tooth 110 is formed between each of the second groove portions 117 and its adjacent third groove portion 119. The width of the second groove portion 117 of the stator 11 is e times the width of the second convex tooth 110; the width of the third groove portion 119 of the stator 11 is f times the width of the second convex tooth 110; every two adjacent The second groove portions 117 include 2t second protruding teeth 110; the width of the first groove portion 124 of the mover 12 is k times the width of the first protruding teeth 121. Where e, f, m, Q, t, k, and n are configuration parameters. When the number of phases of the motor device is P, the total number S of the groove portions 115 has a first configuration relationship with the phase number P; e and f have a second configuration relationship; m, P, Q, t, k, e, and f have the first Three configuration relationships; n, m, k, and Q have a fourth configuration relationship.
本發明根據上述配置關係所提出的電機裝置具有相當優異的性能,請參考第7A圖至第7D圖,為本發明所提出之電機裝置的其中一個實施例,其中定子為3相(P=3)12槽、動子12的第一凸齒數n=38。第7A圖至第7D圖為動子12往左前進90度、180度、270度與360度電氣角的狀況。由第7A圖至第7D圖可以看出,定子11的第二凸齒110與動子12的第一凸齒121所對應重疊的凸齒寬度W01+W02+W03+W04的總和在四種電氣角時,幾乎固定不變,可預期動子12的運轉過程中,在各個電氣角時定子11的第二凸齒110與動子12的第一凸齒121所對應重疊的凸齒寬度W01+W02+W03+W04的總和亦幾乎固定。對於一般雙凸極電機裝置(包括馬達與發電機)的設計而言,假若定子11與動子12對應重疊的凸齒寬度W01+W02+W03+W04的總和在運轉時的變異量大,頓轉轉矩則大;假若定子11與動子12對應重疊的凸齒寬度W01+W02+W03+W04的總和在運轉時的變異量小,頓轉轉矩則小。本發明所提出之電機裝置的定子11與動子12對應重疊的凸齒寬度W01+W02+W03+W04的總和在運轉時幾乎固定不變,因此頓轉轉矩極低,不像一般雙凸極電機都有極大的頓轉轉矩。 The motor device according to the above configuration relationship of the present invention has quite excellent performance. Please refer to FIGS. 7A to 7D, which are one embodiment of the motor device proposed by the present invention, wherein the stator has three phases (P=3). The number of the first convex teeth of the 12-slot and the mover 12 is n=38. 7A to 7D are diagrams in which the mover 12 advances 90 degrees, 180 degrees, 270 degrees, and 360 degrees of electrical angle to the left. It can be seen from FIG. 7A to FIG. 7D that the sum of the convex tooth widths W01+W02+W03+W04 of the second convex teeth 110 of the stator 11 and the first convex teeth 121 of the mover 12 is in four kinds of electrical When the angle is almost constant, it is expected that the convex tooth width W01+ of the second convex tooth 110 of the stator 11 and the first convex tooth 121 of the mover 12 overlap at each electrical angle during the operation of the mover 12. The sum of W02+W03+W04 is also almost fixed. For the design of a general doubly salient motor device (including a motor and a generator), if the sum of the convex tooth widths W01+W02+W03+W04 of the stator 11 and the mover 12 overlaps, the variation amount during operation is large. The turning torque is large; if the sum of the convex tooth widths W01+W02+W03+W04 of the stator 11 and the mover 12 overlaps, the variation amount during the operation is small, and the torque is small. The sum of the convex tooth widths W01+W02+W03+W04 of the stator 11 and the mover 12 of the motor device proposed by the present invention is almost constant during operation, so the torque is extremely low, unlike the general biconvex The pole motor has a great torque.
因此,本發明之主要目的在於提供一種電機裝置,藉由配置參數的調整,容易達成多磁極又具有低的頓轉轉矩,當配合輔助的場繞組時,可藉由調整場繞組的電流來控制氣隙磁通密度,達到弱磁或增磁的功能,極適合用在直驅式電動車馬達或風力發電機等的應用。 Therefore, the main object of the present invention is to provide a motor device that can easily achieve multiple magnetic poles and low torques by adjusting the configuration parameters.

The pair of fifth groove portions 280 that span the second groove portion 117 may further include the armature winding 13 as needed.
本發明所提出的電機裝置9具有特殊的配置參數與配置關係,可以強化並彈性地調整電機裝置9的性能。以下將詳細說明各項配置參數與配置關係,並請參見第6A圖至第6C圖。 The motor device 9 proposed by the present invention has a special configuration parameter and configuration relationship, and can strengthen and elastically adjust the performance of the motor device 9. The configuration parameters and configuration relationship will be described in detail below, and please refer to Figures 6A to 6C.
配置參數包含有a、b、e、f、t、k、m、P、Q與S,其中t、k、m、P、Q與S,均大於0,a與b為大於等於0的整數,且其中t、P、Q、S為正整數;每二個相鄰的第二槽部117之間包含2t個第二凸齒110;k為動子12的第一槽部124的寬度與第一凸齒121寬度的比值;e為定子11之第二槽部117的寬度與第二凸齒110寬度的比值;f為定子11之第三槽部119寬度與第二凸齒110寬度的比值;實際設計時,上述配置參數會依設計最佳化而可能不會有整數關係。另,於計算動子12的第一凸齒121的齒數n時,e與f可取值0,其實際意義為第二槽部117的槽寬相對於第二凸齒110寬度的比值極小,例如小於0.3齒寬。 The configuration parameters include a, b, e, f, t, k, m, P, Q, and S, where t, k, m, P, Q, and S are all greater than 0, and a and b are integers greater than or equal to 0. And wherein t, P, Q, and S are positive integers; each of the two adjacent second groove portions 117 includes 2t second protruding teeth 110; k is the width of the first groove portion 124 of the mover 12 and The ratio of the width of the first convex tooth 121; e is the ratio of the width of the second groove portion 117 of the stator 11 to the width of the second convex tooth 110; f is the width of the third groove portion 119 of the stator 11 and the width of the second convex tooth 110 Ratio; in actual design, the above configuration parameters may be optimized by design and may not have an integer relationship. In addition, when calculating the number of teeth n of the first convex teeth 121 of the mover 12, e and f may take a value of 0, and the practical meaning is that the ratio of the groove width of the second groove portion 117 to the width of the second convex tooth 110 is extremely small. For example less than 0.3 tooth width.
電機裝置之相數為P;溝部115之總數量為S;上述配置參數必須符合第一配置關係:S=2 * P * Q;上述配置參數必須符合第二配置關係:在不同的k時,e與f必須滿足e=(k+1)a且f=(k+1)b+k-1、或e=(k+1)a+1且f=(k+1)b+k-2、、、、或e=(k+1)a+k-1且f=(k+1)b;第三配置關係:m=2 * P * Q *(2 *(t *(1+k)-k)+e+f);第四配置關係:n=m/(k+1)、或n=m/(k+1)±1、或n=m/(k+1)±Q。 The number of phases of the motor device is P; the total number of the groove portions 115 is S; the above configuration parameters must conform to the first configuration relationship: S = 2 * P * Q; the above configuration parameters must conform to the second configuration relationship: at different k, e and f must satisfy e=(k+1)a and f=(k+1)b+k-1, or e=(k+1)a+1 and f=(k+1)b+k- 2, , , or e=(k+1)a+k-1 and f=(k+1)b; third configuration relationship: m=2 * P * Q *(2 *(t *(1+ k)-k)+e+f); fourth configuration relationship: n=m/(k+1), or n=m/(k+1)±1, or n=m/(k+1)± Q.
上述第二配置關係是以k為自變數,當k的值增加時,第二配置關係會產生更多的組合方式。例如當k=1時,第二配置關係可以進一步設定為(e=2a且f=2b)。 The second configuration relationship is that k is an independent variable, and when the value of k is increased, the second configuration relationship generates more combinations. For example, when k=1, the second configuration relationship may be further set to (e=2a and f=2b).
當k=2時,第二配置關係可以進一步設定為(e=3a且f=3b+1);或(e=3a+1且f=3b)。 When k=2, the second configuration relationship may be further set to (e=3a and f=3b+1); or (e=3a+1 and f=3b).
當k=3時,第二配置關係可以進一步設定為(e=4a且f=4b+2)或(e=4a+1且f=4b+1)或(e=4a+2且f=4b);當k=4、5、6、7、.....時,可依此類推。亦即,針對每一個預設的配置參數k的值,e與f只要滿足上述的任何一個第二配置關係即可。 When k=3, the second configuration relationship may be further set to (e=4a and f=4b+2) or (e=4a+1 and f=4b+1) or (e=4a+2 and f=4b) ); when k=4, 5, 6, 7, . . . , can be deduced by analogy. That is, for each of the preset values of the configuration parameter k, e and f may satisfy any one of the second configuration relationships described above.
上述的第四配置關係,當P=1時,即單相馬達,適用n=m/(k+1);當P≧2時,即多相馬達,適用n=m/(k+1)±1或n=m/(k+1)±Q。 The fourth configuration relationship described above, when P=1, that is, a single-phase motor, n=m/(k+1) is applicable; when P≧2, that is, a multi-phase motor, n=m/(k+1) is applicable. ±1 or n=m/(k+1)±Q.
根據上述的的配置參數與配置關係,底下提出幾個配置實施例: According to the above configuration parameters and configuration relationship, several configuration embodiments are proposed below:
k=1、t=1、P=3、Q=2,取a=1,b=1則得到e=2、f=2,因此m=2*3*2*(2*(2-1)+2+2)=12*6=72,n=72/2±1=35或37;n=72/2±2=34或38。 k=1, t=1, P=3, Q=2, take a=1, b=1 to get e=2, f=2, so m=2*3*2*(2*(2-1 +2+2)=12*6=72, n=72/2±1=35 or 37; n=72/2±2=34 or 38.
所以動子12的第一凸齒121的數量n可以是35、37、34或38。 Therefore, the number n of the first convex teeth 121 of the mover 12 may be 35, 37, 34 or 38.
k=1、t=2、P=3、Q=2,取a=1,b=1則得到e=2、f=2,因此m=2*3*2*(2*(4-1)+2+2)=12*10=120,n=120/2±1=61或59;n=120/2±2=62或58。 k=1, t=2, P=3, Q=2, take a=1, b=1 to get e=2, f=2, so m=2*3*2*(2*(4-1 +2+2)=12*10=120, n=120/2±1=61 or 59; n=120/2±2=62 or 58.
所以動子12的第一凸齒121的數量n可以是61、59、62或58。 Therefore, the number n of the first convex teeth 121 of the mover 12 may be 61, 59, 62 or 58.
k=2、t=1、P=3,Q=2, 令a=1、b=0,取(e=3a且f=3b+1),得到e=3、f=1,因此m=2*3*2*(2*(3-2)+3+1)=12*6=72,n=72/3±1=23或25;n=72/3±2=22或26。 k=2, t=1, P=3, Q=2, Let a=1, b=0, take (e=3a and f=3b+1), get e=3, f=1, so m=2*3*2*(2*(3-2)+3 +1)=12*6=72, n=72/3±1=23 or 25; n=72/3±2=22 or 26.
