切換式磁阻馬達及其轉子Switched reluctance motor and its rotor

本發明係關於一種切換式磁阻馬達，尤指該切換式馬達及其轉子之構造發明者。The present invention relates to a switched reluctance motor, and more particularly to the inventor of the switching motor and its rotor.

由於稀土元素價格日益高漲，導致具稀土元素成分之強力磁石價格也居高不下，進而影響永磁馬達之成本與競爭力。Due to the increasing price of rare earth elements, the price of strong magnets with rare earth elements is also high, which in turn affects the cost and competitiveness of permanent magnet motors.

由於切換式磁阻馬達為無須使用稀土族強力磁石之結構，具有結構簡單製造成本低、結構堅固可應用於惡劣環境，且具有效率及轉矩/轉動慣量比高，以及具彈性運轉的能力與容錯性高、安全及可靠等多項優點，非常適合做為動力馬達，又加上目前之控制技術提升，該切換式磁阻馬達已成為各大馬達廠商競相研發之產品。Since the switched reluctance motor is a structure that does not require the use of a rare earth strong magnet, the structure is simple, the manufacturing cost is low, the structure is strong, and it can be applied to a harsh environment, and has high efficiency and torque/moment of inertia ratio, and the ability to operate elastically. It has many advantages such as high fault tolerance, safety and reliability. It is very suitable as a power motor, and with the improvement of current control technology, the switched reluctance motor has become a product developed by major motor manufacturers.

惟切換式磁阻馬達因本身結構問題，其運轉時之轉矩漣波(torque ripple)較大，導致振動與噪音等問題。為克服此一問題，目前大多藉由複雜的控制迴路以期得到良好的控速效果，進而改善振動與噪音之問題。然而，目前未見有人對該切換式磁阻馬達本身之構造，提出創新的技術方案來解決切換式磁阻馬達運轉時轉矩漣波偏大之技術問題。However, due to its structural problems, the switched reluctance motor has a large torque ripple during operation, which causes vibration and noise. In order to overcome this problem, most of the current control loops are used to obtain a good speed control effect, thereby improving the vibration and noise problems. However, no one has seen the construction of the switched reluctance motor itself, and an innovative technical solution has been proposed to solve the technical problem of large torque chopping during the operation of the switched reluctance motor.

本發明之主要目的在於提供一種切換式磁阻馬達及其轉子，希藉此發明，解決現有切換式磁阻馬達因本身幾何結構特性，於轉子運轉時產生轉矩漣波而造成振動與噪音之問題。The main object of the present invention is to provide a switched reluctance motor and a rotor thereof, and the present invention solves the problem of the existing switched reluctance motor due to its own geometry.

本案發明人曾進一步以試作實物樣品進行實驗測試，請配合參閱表一與附件一之分析數據，其中，分析之樣品中，包含未偏移之轉子(case A)、區塊偏移1度之轉子(case B)、區塊偏移3度之轉子(case C)、區塊偏移5度之轉子(case D)以及區塊偏移7度之轉子(case E)等五件實物樣品，該些具有區塊偏移之轉子是以轉子極齒中段形成一偏移區塊之型態為基礎，其實驗測試結果如下： The inventor of the case has further tested the physical samples with the test samples. Please refer to the analysis data in Table 1 and Annex 1. The analyzed samples include the rotor with no offset (case A) and the block offset of 1 degree.

由表一可證明，轉子之區塊偏移3度~5度時，確能明顯地降低磁阻馬達運轉之轉矩漣波，進而減少磁阻馬達運轉之振動與噪音。It can be proved from Table 1 that when the block of the rotor is shifted by 3 to 5 degrees, the torque ripple of the reluctance motor can be significantly reduced, thereby reducing the vibration and noise of the reluctance motor.

再請參閱表二與附件二所示之分析數據，以下進一步就本發明各式較佳實施例之轉子偏移方式分析說明，其中，樣品0為未有區塊偏移(即偏移0度)之轉子，並以具有複數個區塊偏移之轉子極齒之轉子為基礎，依序設定樣品1(case 1)為具有單一區塊(後段區塊)偏移3度之轉子(即轉子極齒沿軸區分為2段)、樣品2(case 2)為具有二段間隔排列之區塊偏移3度之轉子(即轉子極齒沿軸向區分為4段)、樣品3(case 3)為具有單一區塊(即後段區塊)偏移5度之轉子(即轉子極齒沿軸向區分為2段)、樣品4(case 4)為具有二段間隔排列之區塊偏移5度之轉子(即轉子極齒沿軸向區分為4段)，以前述樣品1(case 1)至樣品4(case 4)與樣品0相較： Referring to the analysis data shown in Table 2 and Annex 2, the rotor offset mode analysis of the preferred embodiments of the present invention is further described below, wherein the sample 0 has no block offset (ie, offset 0 degrees). Rotor, and based on the rotor with a plurality of block offset rotor pole teeth, sequentially set sample 1 (case 1) to a rotor with a single block (rear block) offset by 3 degrees (ie rotor) The pole teeth are divided into 2 segments along the axis), and the sample 2 (case 2) is a rotor with a block interval of 3 degrees arranged in two intervals (ie, the rotor teeth are divided into 4 segments in the axial direction), and sample 3 (case 3) ) is a rotor with a single block (ie, the back block) offset by 5 degrees (ie, the rotor teeth are divided into 2 segments in the axial direction), and sample 4 (case 4) is a block offset with a two-segment interval. The rotor of the degree (ie, the rotor teeth are divided into 4 segments in the axial direction), compared with sample 0 in the aforementioned sample 1 (case 1) to sample 4 (case 4):

由以上所述之實驗測試結果可知，轉子之區塊偏移之區塊數量增加，其降低磁阻馬達運轉產生轉矩漣波之效果更加明顯。It can be seen from the experimental test results described above that the number of blocks in which the block of the rotor is offset increases, and the effect of reducing the torque ripple generated by the reluctance motor operation is more obvious.
