Description
本創作係有關於一種鼠籠轉子相關之技術領域，尤其是一種短路環之導電銅片快速熔融結構。 This creation is related to a technical field related to squirrel-cage rotors, especially a rapid melting structure of a conductive copper sheet of a short-circuit ring.
馬達的設計上，除了利用交流電相位的變化以產生變動的磁場外，更可以利用變動的周圍磁場，感應中間轉子產生磁場，如此轉子可以不必再纏繞線圈，亦不需有碳刷等構造，而可簡化轉子的構造，請參閱第4圖所示，如感應電動機(單相和三相)的鼠籠轉子，在積疊的矽鋼片鐵心91中穿插複數導電銅片92(或棒)，兩端利用短路環93變成鼠籠型，經周圍變動磁場感應，產生渦流及磁力而旋轉，連動同心設置於矽鋼片鐵心91之轉軸94轉動，俾以輸出動力。 In the design of the motor, in addition to utilizing the change of the phase of the alternating current to generate a varying magnetic field, it is also possible to use the varying surrounding magnetic field to induce the magnetic field generated by the intermediate rotor, so that the rotor can be wound without the need of a carbon brush or the like. The structure of the rotor can be simplified, as shown in Fig. 4, such as the squirrel-cage rotor of the induction motor (single-phase and three-phase), in which a plurality of conductive copper sheets 92 (or rods) are interposed in the stacked silicon steel core 91, two The short-circuit ring 93 is turned into a squirrel-cage type, and is induced by a surrounding magnetic field to generate a vortex and a magnetic force to rotate, and the rotating shaft 94 concentrically disposed on the silicon steel sheet core 91 is rotated to output power.
習知鑄造工藝成形之短路環93作法，係配合鑄造模具(圖中未示)將凸出於矽鋼片鐵心91兩端之各導電銅片92繞圍，並澆注銅鑄造液至鑄造模具中，使銅鑄造液包覆各導電銅片92，待銅鑄造液冷卻後即可得與各導電銅片92一體形成之短路環93。1 The short-circuit ring 93 formed by the casting process is formed by a casting mold (not shown) surrounding the conductive copper sheets 92 protruding from both ends of the silicon steel sheet core 91, and pouring the copper casting liquid into the casting mold. The copper casting solution is coated with the conductive copper sheets 92. After the copper casting liquid is cooled, the short-circuit ring formed integrally with the conductive copper sheets 92 is obtained.
上述鑄造工藝過程中，導電銅片92兩自由端過大的面積，會降低銅鑄造液整體之溫度，造成銅鑄造液無法對導電銅片92外周面形成熔融，使得導電銅片92與短路環93間形成虛接。 During the above casting process, the excessively large area of the two free ends of the conductive copper sheet 92 reduces the temperature of the copper casting liquid as a whole, and the copper casting solution cannot melt the outer peripheral surface of the conductive copper sheet 92, so that the conductive copper sheet 92 and the short-circuit ring 93 Form a virtual connection.
有鑑於上述習知技藝之問題與缺失，本創作之主要目的，乃在於提供一種短路環之導電銅片快速熔融結構，藉由導電銅片之結構改良，避免短路環鑄造工藝形成短路環時衍生之結構缺失。 In view of the above problems and shortcomings of the prior art, the main purpose of the present invention is to provide a rapid melting structure of a conductive copper piece of a short-circuit ring, which is improved by the structure of the conductive copper sheet to avoid the formation of a short-circuit ring when the short-circuit ring casting process is formed. The structure is missing.
根據本創作上述目的，係包括於一導電銅片兩末端分別設有一熔融段、及於熔融段設有複數裁切部，俾以限縮該熔融段之總面積。藉由上述構件之組成，當導電銅片實施於短路環鑄造工藝過程中，可被其澆注之銅鑄造液局部且快速的形成熔融，確保導電銅片與短路環熔融形成一體。 According to the above object of the present invention, a melting section is respectively disposed at both ends of a conductive copper sheet, and a plurality of cutting portions are disposed in the melting section to limit the total area of the melting section. By the composition of the above components, when the conductive copper sheet is implemented in the short-circuit ring casting process, the copper casting liquid cast by it can be locally and rapidly melted, and the conductive copper sheet is melted and integrated with the short-circuit ring.
