Description
本發明係關於一種同步馬達，特別係關於一種適用於同步馬達之配重結構。 The present invention relates to a synchronous motor, and more particularly to a counterweight structure suitable for use in a synchronous motor.
馬達於現今社會中，無論工業上或者民生方面皆為不可或缺之設備，於近年來馬達的技術也日新月異，市面上馬達種類繁多，相較於其他近代馬達，同步馬達因其轉子與定子旋轉磁場為同步旋轉，因此沒有感應電流，也無二次銅損，所以具有能量轉換效率高、製程簡單、不須另投入大量資金購買加工設備、生產成本低等優點。 In today's society, motors are indispensable equipments in terms of industry or people's livelihood. In recent years, the technology of motors has also changed with each passing day. There are many types of motors on the market. Compared with other modern motors, synchronous motors rotate with their rotors and stators. The magnetic field is synchronously rotated, so there is no induced current and no secondary copper loss, so it has the advantages of high energy conversion efficiency, simple process, no need to invest a large amount of money to purchase processing equipment, and low production cost.
惟，同步馬達之轉子容易具有偏擺、動平衡偏差量等缺失，為克服此問題業界便發展出幾種配重之方式，如圖1所示，該轉子90係由一本體91及穿設於該本體91之一主軸92所構成，該本體91之兩端具有一第一端面911及一第二端面912，該第一端面911延伸至該第二端面912之方向為一軸向A，該本體91軸向A開設複數長條形之穿孔93，各該穿孔93間成形複數連結部94，習知配重之方式係藉由於該本體91較重之一側的連結部94開設複數配重孔95，藉此使該本體91整體的重量均衡，惟，此種方式容易使該轉子90之結構脆弱，大幅提高損壞之風險。 However, the rotor of the synchronous motor is prone to eccentricity, dynamic balance deviation, etc. In order to overcome this problem, the industry has developed several ways of weighting. As shown in Fig. 1, the rotor 90 is composed of a body 91 and a through-body. The main body 91 has a first end surface 911 and a second end surface 912. The first end surface 911 extends to the second end surface 912 in an axial direction A. A plurality of long-shaped perforations 93 are formed in the axial direction A of the main body 91, and a plurality of connecting portions 94 are formed between the perforations 93. The weight is conventionally created by the connecting portion 94 on the heavier side of the main body 91. The weight 95 is thereby balanced by the weight of the body 91 as a whole, but in this manner, the structure of the rotor 90 is easily weakened, and the risk of damage is greatly increased.
又，如圖2所示，為另一種習知的配重方式，使用者於該本體91較輕之一側黏貼一平衡土B，藉此增加重量使該轉子90之重量平衡，惟此方式應用於高溫、低溫、高濕等惡劣環境與高轉速之應用場合，易使該平衡土B自該轉子90脫落，大幅降低可靠度與縮短電機壽命。 Moreover, as shown in FIG. 2, in another conventional weighting manner, the user adheres a balance soil B to one side of the body 91, thereby increasing the weight to balance the weight of the rotor 90. When applied to harsh environments such as high temperature, low temperature, high humidity and high speed, it is easy to make the balance soil B fall off from the rotor 90, which greatly reduces the reliability and shortens the life of the motor.
本發明提供一種適用於同步馬達之配重結構，其主要目的係提供一種避免破壞馬達結構，方便又有效之適用於同步馬達之配重結構。 The invention provides a weight structure suitable for a synchronous motor, and the main purpose thereof is to provide a weight structure suitable for a synchronous motor that avoids damaging the motor structure and is convenient and effective.
為達前述目的，本發明提供一種適用於同步馬達之配重結構，供以裝設於同步馬達之一轉子，該轉子係由一本體及穿設於該本體之一主軸所構成，該本體具有相對之一第一端面及一第二端面，而該適用於同步馬達之配重結構，包括：二壓合件，結合於該本體之該第一端面及該第二端面，該壓合件具有一軸孔，該轉子之主軸係穿設於該軸孔，該壓合件具有一第一側面及一第二側面及連接該第一側面及該第二側面之一圓周面，該第一側面對該轉子之本體，該第二側面或該圓周面具有至少一配重部。 To achieve the foregoing objective, the present invention provides a weight structure suitable for a synchronous motor, which is provided with a rotor mounted on a synchronous motor, the rotor being composed of a body and a main shaft penetrating the body, the body having a first end surface and a second end surface, and the weight structure suitable for the synchronous motor, comprising: a second pressing member coupled to the first end surface and the second end surface of the body, the pressing member has a shaft hole, the main shaft of the rotor is disposed in the shaft hole, the pressing member has a first side surface and a second side surface and a circumferential surface connecting the first side surface and the second side surface, the first side pair The body of the rotor, the second side or the circumferential surface has at least one weight.
由前述可知，本發明適用於同步馬達之配重結構主要係藉由於該轉子之本體的第一端面及第二端面分別結合該壓合件，再依需求調整該壓合件對應該本體較重或較輕一側之配重部，若對應轉子重量較重之一側，便調整配重部使壓合件於重量較重之一側的重量減少，若對應轉子重量較輕之一側，便調整配重部使壓合件於重量較輕之一側的重量增加，以達到配重之效果，進而達成提供一種避免破壞馬達結構，方便又有效之適用於同步馬達之配重結構。 It can be seen from the foregoing that the weighting structure of the present invention is mainly applied to the weighting structure of the synchronous motor, mainly because the first end surface and the second end surface of the body of the rotor are respectively combined with the pressing member, and then the pressing member is adjusted according to requirements to be correspondingly heavy. Or the weight portion of the lighter side, if the weight of the rotor is one of the heavier sides, adjust the weight portion to reduce the weight of the pressing member on one side of the heavier weight, if the weight of the rotor is lighter than one side, Adjusting the weight portion increases the weight of the pressing member on one side of the lighter weight to achieve the effect of the weight, thereby achieving a weight-reducing structure suitable for the synchronous motor that is convenient and effective to avoid damage to the motor structure.
