Description
本發明係一種磁阻馬達，尤指開關式磁阻馬達(switched reluctance motor, SRM)之改良構造。
The invention is a reluctance motor, in particular an improved configuration of a switched reluctance motor (SRM).
近年來由於高科技產業的發達，各種技術都在不斷的創新，以期望使其相關產品能夠達到更佳的品質與性能，在現今許多高科技產品，例如：電動機車、電動汽車、洗衣機、電冰箱、跑步機…等等，都須依賴馬達來驅動，才能夠發揮功能。所以在現在的馬達也不能只注重實用性，還要更進一步設計出高性能、高效率的馬達。一般的馬達的都包含轉子和定子，轉子為可旋轉的部份，定子為固定不動的部份，提供周圍的磁場，馬達係由外界提供一電源通過轉子或定子，使產生磁力相互作用而旋轉。由於磁場的磁力，可由永久磁鐵或電磁鐵產生，因此馬達的轉子或定子，都可以是電磁鐵或永久磁鐵。然而，永磁無刷馬達磁鐵所使用的釹（Nd）等稀土金屬(Rare-earth Metal；RE或REM)的價格不斷上漲，且市場價格也會隨著時間的不同，有時會出現2至3倍的變動，因此會影響馬達廠商對於未來穩定量產的計畫。In recent years, due to the development of high-tech industries, various technologies are constantly innovating in the hope that their related products can achieve better quality and performance. In today's many high-tech products, such as: electric motor cars, electric cars, washing machines, electricity Refrigerators, treadmills, etc., must rely on the motor to drive, in order to function. Therefore, in the current motor, we can not only focus on practicality, but also design a high-performance, high-efficiency motor. A typical motor includes a rotor and a stator. The rotor is a rotatable part. The stator is a stationary part that provides a surrounding magnetic field. The motor is supplied with a power source through the rotor or the stator to cause a magnetic interaction to rotate. . Since the magnetic force of the magnetic field can be generated by a permanent magnet or an electromagnet, the rotor or the stator of the motor can be an electromagnet or a permanent magnet. However, the price of rare earth metals such as niobium (Nd) used in permanent magnet brushless motor magnets is rising, and the market price will sometimes vary from time to time. Three times the change, it will affect the motor manufacturers' plans for stable mass production in the future.
因此市面上出現一種不使用永久磁鐵的開關式磁阻馬達(switched reluctance motor, SRM)，因此馬達廠商可以制定未來穩定量產的計畫，而且成本也會較一般使用磁鐵之馬達低，因此使該開關式磁阻馬達近年來也漸漸被廣泛應用，該開關式磁阻馬達除了成本低之外，由於該開關式磁阻馬達係利用磁阻轉矩運轉，不需要使用永久磁鐵，因此結構堅固，可承受高轉速所產生的離心力，所以經常被應用在高速的場合，且開關式磁阻馬達具有能量密度高、啟動轉矩大、調速性能好、轉矩與慣量比大、且因結構簡單而更有低的製造成本優點，所以該開關式磁阻馬達有逐漸被廣泛使用的趨勢，成為各種科技產品的驅動動力源。Therefore, there is a switched reluctance motor (SRM) that does not use permanent magnets. Therefore, motor manufacturers can formulate plans for stable mass production in the future, and the cost will be lower than that of motors that generally use magnets. The switched reluctance motor has been widely used in recent years. In addition to the low cost, the switched reluctance motor operates with reluctance torque and does not require permanent magnets. It can withstand the centrifugal force generated by high speed, so it is often used in high speed applications, and the switched reluctance motor has high energy density, large starting torque, good speed regulation performance, large torque to inertia ratio, and The simple and low manufacturing cost advantage, the switch reluctance motor has a tendency to be widely used, and has become a driving power source for various technology products.
然而，由於該開關式磁阻馬達係利用磁阻轉矩運轉，所以不需要使用永久磁鐵來產生轉矩轉動，而因為該開關式磁阻馬達不含磁性元件，因此該開關式磁阻馬達的感測元件係以光柵感應元件( light barrier )為主，而非磁感元件，例如霍爾元件；光柵感應元件兩邊包括一光源器與一光感測器，及一間格寬度柵欄，該柵欄遮住光源而產生明暗變化而讓該光感測器接收，但是，使用光柵感應元件的缺點在於易受到粉塵遮光的影響，而影響該光柵感應元件的感應靈敏度，且而該柵欄呈直立狀，因此令該光柵感應元件體積也較一般的感應元件大，且光柵感應元件的成本也較高，因此，本發明者認為將該霍爾元件應用於該開關式磁阻馬達，則可改善該光柵感應元件上述不足之處。However, since the switched reluctance motor operates using reluctance torque, there is no need to use a permanent magnet to generate torque rotation, and since the switched reluctance motor does not contain a magnetic element, the switched reluctance motor The sensing element is mainly a light barrier, rather than a magnetic sensing element, such as a Hall element; the grating sensing element includes a light source and a light sensor on both sides, and a grid width fence, the fence Covering the light source to produce a change in brightness and darkness for the light sensor to receive, however, the use of the grating sensing element has the disadvantage of being susceptible to dust shading, affecting the sensing sensitivity of the grating sensing element, and the fence is upright, Therefore, the grating sensing element is also larger in volume than the general sensing element, and the cost of the grating sensing element is also higher. Therefore, the inventors believe that the application of the Hall element to the switched reluctance motor can improve the grating. The above disadvantages of the sensing element.
然而，本發明者於研究創作過程中上嘗試直接將無刷直流馬達之霍爾元件裝設於習知之該開關式磁阻馬達上，但，該習知之該開關式磁阻馬達內轉子與定子並沒有永久磁場，故霍爾元件無法感應周圍迴轉磁場之變化，進而無法偵測未通電時轉子凸極之位置;又由於該直流無刷馬達轉子本身之磁場，或外加磁鐵，皆為連續磁場，此種磁場架構同時存在N極與S極，所以可使用該雙極霍爾元件，能使其正常偵測該轉子位置，也因此該雙極霍爾元件可以減低周圍磁場干擾雜訊，降低該轉子錯誤位置雜訊的產生，然而該開關式磁阻馬達之轉子磁場架構，係對應該轉子凸極的磁場，所以無法使用連續磁場，也意即無法直接使用該雙極霍爾元件，來偵測該轉子位址，因此，本發明者認為將霍爾元件應用於該開關式磁阻馬達上仍有可改良改進之處。
However, the inventors attempted to directly mount the Hall element of the brushless DC motor to the conventional switched reluctance motor during the research and creation process. However, the conventional rotor and stator of the switched reluctance motor are known. There is no permanent magnetic field, so the Hall element can not sense the change of the surrounding rotating magnetic field, and thus can not detect the position of the salient pole of the rotor when the power is not energized; and because of the magnetic field of the DC brushless motor rotor or the external magnet, it is a continuous magnetic field. The magnetic field structure has N pole and S pole at the same time, so the bipolar Hall element can be used to detect the rotor position normally, and therefore the bipolar Hall element can reduce the surrounding magnetic field to interfere with the noise and reduce the noise. The rotor error position noise is generated. However, the rotor magnetic field structure of the switched reluctance motor is a magnetic field corresponding to the salient pole of the rotor, so the continuous magnetic field cannot be used, that is, the bipolar Hall element cannot be directly used. The rotor address is detected, and therefore, the inventors believe that there are still improvements in the improvement of the Hall element applied to the switched reluctance motor.
為解決先前技術不足之處，因此本發明者提出一種開關式磁阻馬達(switched reluctance motor, SRM)之改良構造，該開關式磁阻馬達包括一轉子組，於該轉子組外側方套設一定子組，且該轉子組包括一軸桿，於該軸桿外側壁沿環向間隔設置複數凸極，更設複數對應各凸極之磁性元件，該些磁性元件設於各凸極表面，或設於該軸桿軸設之盤體端面，且該盤體與該轉子組連動；及一單極霍爾組件，該單極霍爾組件設於任一磁性元件之一側方，該單極霍爾組件可供分別感應各磁性元件。In order to solve the deficiencies of the prior art, the inventors propose an improved structure of a switched reluctance motor (SRM), which includes a rotor set, and is sleeved on the outer side of the rotor set. a sub-group, and the rotor set includes a shaft, and a plurality of salient poles are arranged along the circumferential direction of the outer sidewall of the shaft, and a plurality of magnetic elements corresponding to the salient poles are further disposed, and the magnetic elements are disposed on the surface of each salient pole, or And a single-pole Hall assembly disposed on one side of any one of the magnetic components, the monopole Hall assembly The components are adapted to sense the respective magnetic components separately.
因此，本發明者使用該單極霍爾元件組，且針對不同磁性元件之磁力高斯值來搭配不同種之單極霍爾元件組，藉此以正確感應各磁性元件所對應的轉子凸極，進而能使該單極霍爾元件組正常偵測該些凸極之位址，進而解決一般直流無刷馬達之雙極霍爾元件無法直接應用於該開關式磁阻馬達之問題；經由本發明使得該單極霍爾組件得以應用於該開關式磁阻馬達，因此能達到縮減該開關式磁阻馬達體積及減少製造成本；而且使用該單極霍爾組件之該開關式磁阻馬達就能較不受粉塵所影響，例如該開關式磁阻馬達應用於鋸木頭之電鋸時，就較不易受到木屑的影響，藉此令該開關式磁阻馬達在使用上得以應用在更多的用途上。
Therefore, the present inventors use the monopole Hall element group and match different kinds of monopole Hall element groups for magnetic Gauss values of different magnetic elements, thereby correctly sensing the rotor salient poles corresponding to the respective magnetic elements. Further, the monopole Hall element group can normally detect the addresses of the salient poles, thereby solving the problem that the bipolar Hall element of the general DC brushless motor cannot be directly applied to the switched reluctance motor; The unipolar Hall assembly can be applied to the switched reluctance motor, thereby reducing the size of the switched reluctance motor and reducing the manufacturing cost; and the switched reluctance motor using the unipolar Hall assembly can It is less affected by dust. For example, when the switched reluctance motor is applied to saws for sawing wood, it is less susceptible to wood chips, so that the switched reluctance motor can be used in more applications. on.
