Description
本創作係有關於一種轉子的磁性元件結構,尤其指一種應用於風扇馬達的轉子的磁性元件結構。The present invention relates to a magnetic element structure of a rotor, and more particularly to a magnetic element structure applied to a rotor of a fan motor.
一般習知無刷直流風扇馬達的基本結構可分為定子與轉子部分,因馬達的轉動方式是靠兩個磁場體的交互垂直利作用而使之轉動,所以基本上就是要有兩個可以製造出磁場的來源體,基本上這兩個可以製造出磁場的來源體就是用電磁鐵與永久磁鐵來設計,而電磁鐵與永久磁鐵的設計方式大致可分為靜止與轉動兩個部分,靜止的部分稱為定子其包括軸、電樞心及電樞繞組,主要功用是產生磁場,以與外部永久磁鐵的磁場作用,產生轉矩。轉動的部分稱為轉子,其包括永久磁鐵與扇葉,經由磁場的相互作用產生轉矩及帶動扇葉轉動。Generally, the basic structure of a conventional brushless DC fan motor can be divided into a stator and a rotor portion. Since the rotation mode of the motor is rotated by the interaction of the two magnetic field bodies, basically two items can be manufactured. The source of the magnetic field, basically the two sources that can produce the magnetic field are designed with electromagnets and permanent magnets, and the design of electromagnets and permanent magnets can be roughly divided into two parts, static and rotating, stationary. Partially referred to as the stator, which includes the shaft, the armature core, and the armature winding, the main function is to generate a magnetic field to react with the magnetic field of the external permanent magnet to generate torque. The portion that is rotated is called the rotor, which includes the permanent magnets and the blades, which generate torque through the interaction of the magnetic fields and drive the blades to rotate.
由於目前的無刷直流風扇馬達係利用電子換相技術接收轉子的轉動位置信號及告知定子要換相的時間點,使轉子可以持續的轉動。常用來接收轉子的轉動位置信號的元件主要以霍爾元件為主,利用霍爾元件感應轉子的N-S磁極變換時間點以令驅動電路驅動轉子運轉。但是目前轉子的永久磁鐵的充磁方式為正充磁(斜度為零)或斜充磁,較常用的正充磁要搭配移動霍爾元件的位置找出最佳效率點,但是往往受限於機構上的限制,無法得到最佳換相點,導致振動產生,因此有利用斜充磁來作改善,企以減少換相時產生的振動,卻因此犧牲馬達的效率,導致馬達轉動效率不佳。Since the current brushless DC fan motor uses the electronic commutation technique to receive the rotational position signal of the rotor and inform the stator of the time point of commutation, the rotor can be continuously rotated. The component that is often used to receive the rotational position signal of the rotor is mainly a Hall element. The Hall element senses the N-S magnetic pole of the rotor to change the time point to cause the drive circuit to drive the rotor. However, at present, the permanent magnet of the rotor is magnetized by positive magnetization (slope is zero) or oblique magnetization. The more common positive magnetization is matched with the position of the moving Hall element to find the best efficiency point, but it is often limited by the mechanism. The upper limit, the best commutation point can not be obtained, resulting in vibration, so the use of oblique magnetization to improve, in order to reduce the vibration generated during commutation, but sacrifice the efficiency of the motor, resulting in poor motor rotation efficiency.
綜上,目前的設計存在改善振動與提生效能二者難以兩全其美之問題與缺憾。因此如何克服振動產生並兼提升轉動效能以達到兩全其美,是本創作的課題。In summary, the current design has the problems and shortcomings of improving both the vibration and the effective energy. Therefore, how to overcome the vibration generation and improve the rotation efficiency to achieve the best of both worlds is the subject of this creation.

The slope extends to the underside 112 of the body 11.
請繼續參考第2A圖係為本創作風扇馬達裝置之局部結構組合剖視示意圖;第2B圖係為本創作轉子的磁性元件結構與定子的局部展開示意圖。如圖所示前述的磁性元件10係應用在一風扇馬達裝置30,該風扇馬達裝置30包括一定子31及一轉子32,該定子31設置在一基座33上,該定子31具有一徑向磁面314,該徑向磁面314係由複數矽鋼片311堆疊組成,一繞線組312繞設該複數矽鋼片311。該定子31的下方連接一電路板35其上設有至少一感測元件34例如霍爾(Hall)元件。Please refer to FIG. 2A for a schematic diagram of a partial structural combination of the fan motor device. FIG. 2B is a partial exploded view of the magnetic component structure and the stator of the rotor. The magnetic element 10 as described above is applied to a fan motor unit 30 including a stator 31 and a rotor 32 which is disposed on a base 33 having a radial direction The magnetic surface 314 is composed of a plurality of silicon steel sheets 311 stacked, and a winding group 312 surrounds the plurality of steel sheets 311. Connected to a circuit board 35 below the stator 31 is provided with at least one sensing element 34, such as a Hall element.
該轉子32係對應該定子31,且包括一輪轂321,該輪轂321的外側設有複數扇葉322,該輪轂321的內側設有一鐵殼323,前述的磁性元件10設置在該鐵殼323的內側且間隔對應該定子31,磁性元件10的上側111及下側112之間界定一第一區域114及一第二區域115在該第一區域114下方,該第一區域114係徑向對應該定子31的徑向磁面314,該第二區域115沒有對應該定子31的徑向磁面314,但是鄰近該感測元件34。磁力交界線12的第一垂直部分121位於該第一區域114面對該定子31的徑向磁面314。磁力交界線12的傾斜部分122及第二垂直部份123及第二轉折點125在該第二區域115,且間隔相鄰該感測元件34。The rotor 32 corresponds to the stator 31 and includes a hub 321 . The outer side of the hub 321 is provided with a plurality of blades 322 . The inner side of the hub 321 is provided with an iron shell 323 . The magnetic element 10 is disposed on the iron shell 323 . The inner side and the spacing correspond to the stator 31. The upper side 111 and the lower side 112 of the magnetic element 10 define a first area 114 and a second area 115 below the first area 114. The first area 114 is radially corresponding. The radial magnetic face 314 of the stator 31 does not correspond to the radial magnetic face 314 of the stator 31 but is adjacent to the sensing element 34. The first vertical portion 121 of the magnetic boundary line 12 is located at a radial magnetic face 314 of the first region 114 facing the stator 31. The inclined portion 122 of the magnetic boundary line 12 and the second vertical portion 123 and the second inflection point 125 are in the second region 115 and are spaced adjacent to the sensing element 34.
尤其要說明的是,該磁力交界線12的傾斜部分122係朝該本體10轉動的方向傾斜,該第一區域114及第二區域115的交界處係為磁力交界線12的第一轉折部124。所以當定子31通電時,該徑向磁面314與該磁性元件10產生磁場作用驅動該轉子32轉動,藉由該第一區域114內的磁力交界線12的第一垂直部份121保持定子31與轉子32之間的轉動效率,並藉由該第二區域內的磁力交界線12的傾斜部分122減少本體11的N極及S極換相時產生的振動,並能讓感測元件34找到最佳的換相點,改善習知機構上所造成的結構限制。In particular, the inclined portion 122 of the magnetic boundary line 12 is inclined toward the direction in which the body 10 rotates, and the boundary between the first region 114 and the second region 115 is the first turning portion 124 of the magnetic boundary line 12. . Therefore, when the stator 31 is energized, the radial magnetic surface 314 and the magnetic element 10 generate a magnetic field to drive the rotor 32 to rotate, and the first vertical portion 121 of the magnetic boundary line 12 in the first region 114 holds the stator 31. The rotational efficiency between the rotor 32 and the inclined portion 122 of the magnetic boundary line 12 in the second region reduces the vibration generated when the N and S poles of the body 11 are commutated, and allows the sensing element 34 to find The best commutation point to improve the structural constraints imposed by conventional institutions.
請繼續參考第3A圖係為本創作轉子的磁性元件結構之充磁示意圖;第3B圖係為本創作轉子的磁性元件結構之充磁示意圖。通常磁鐵的充磁方式分為前充磁(Component Magnetization, CM)與後充磁(Post-Assembly Magnetization, PAM)兩種。前充磁係指磁性元件為組裝於馬達轉子之前已有磁性,而後充磁係將未充磁的磁性元件裝於轉子,利用外部電路或充磁機供應瞬間大電流,以產生強大磁場,對轉子內部的磁鐵充磁。本創作的磁性元件10係利用前充磁的方式完成。首先提供一柱狀的充磁器40,該充磁器40係可產生多極磁場,充磁器40的外表面設有數個等角度間隔分佈的間隔部41,間隔部41係作為N極及S極磁場的交界,充磁器40的內部設有電路透過電線連接外部電源46以使充磁器40產生磁場。為了讓前述的磁性元件10的磁力交界線12包括第一垂直部分121、傾斜部分122、第二垂直部份123、第一轉折部124及第二轉折部125,所以該間隔部41設計成具有一第一垂直部份411、一傾斜部分412、一第二垂直部份413、一第一轉折部414及一第二轉折部415。在充磁器40尚未通電時預先將沒有磁性的磁性元件10套設在充磁器40的外側,當充磁器40通電後產生磁場對套設在充磁器40外側的磁性元件10充磁,進而使該磁性元件10具有磁性,同時該間隔部41對應在磁性元件10的位置形成N極及S極之間形成該等磁力交界線12(如第1圖所示),其中間隔部41的第一垂直部份411、傾斜部分412、第二垂直部份413、第一轉折部414及第二轉折部415對應形成該磁力交界線12的第一垂直部分121、傾斜部分122、一第二垂直部份123、第一轉折部124及第二轉折部125(如第1圖所示)。Please refer to FIG. 3A for the magnetization of the magnetic component structure of the rotor of the present invention; FIG. 3B is a schematic diagram of the magnetization of the magnetic component structure of the rotor.

The magnetizer 40 generates a multi-pole magnetic field. The outer surface of the magnetizer 40 is provided with a plurality of equally angularly spaced spacers 41. The spacers 41 serve as N-pole and S-pole magnetic fields. At the interface of the magnetizer 40, an electric circuit is connected to the external power source 46 through the electric wire to cause the magnetizer 40 to generate a magnetic field. In order to allow the magnetic boundary line 12 of the magnetic element 10 to include the first vertical portion 121, the inclined portion 122, the second vertical portion 123, the first turning portion 124, and the second turning portion 125, the spacing portion 41 is designed to have A first vertical portion 411, an inclined portion 412, a second vertical portion 413, a first turning portion 414 and a second turning portion 415.
