Description

具低噪音散熱片的永磁傳動器結構Permanent magnet actuator structure with low noise heat sink

本新型係關於散熱之技術領域，尤指一種具低噪音散熱片的永磁傳動器結構。The present invention relates to the technical field of heat dissipation, and more particularly to a permanent magnet actuator structure with a low noise heat sink.

現今傳動系統中，聯軸器已被廣泛應用於各種機械上。 主要可分為機械式聯軸器以及磁性聯軸器。磁性聯軸器是應用冷次定律(Lenz’s law)以及藉由改變氣隙，以達到傳遞轉矩與動力的功用。同時，在實際應用上具有許多優點，例如：藉由降低馬達的啟動電流，進而延長馬達壽命、減少對電力系統的影響、減少了機械震動和雜訊、以及節約電能等。但是，磁性聯軸器需要將轉差功率消耗在導體轉子上，造成磁性聯軸器之功率與導體轉子的溫度成正比；然而，高溫會使永磁轉子上的永磁體永久退磁，導致磁性聯軸器的損壞。In today's transmission systems, couplings have been widely used in a variety of machinery. Mainly can be divided into mechanical couplings and magnetic couplings. Magnetic couplings use the Lenz's law and by changing the air gap to achieve the transfer of torque and power. At the same time, there are many advantages in practical applications, such as: reducing the motor starting current, thereby extending the life of the motor, reducing the impact on the power system, reducing mechanical vibration and noise, and saving energy. However, magnetic couplings need to dissipate the slip power on the conductor rotor, causing the power of the magnetic coupling to be proportional to the temperature of the conductor rotor; however, the high temperature permanently demagnetizes the permanent magnets on the permanent magnet rotor, resulting in magnetic coupling. Damage to the shaft.

因此，現有一種散熱裝置，係將複數散熱葉片裝設於一導體轉子的邊緣上。當該導體轉子旋轉時，該些散熱葉片可產生氣流以進行散熱。然而，習知散熱裝置未有降低噪音之設計，且散熱效果需要加強。因此降低聯軸器旋轉時所產生的噪音以及增加散熱效果，已成為相關產業業者亟欲解決的問題。Therefore, a conventional heat dissipating device is provided with a plurality of heat dissipating blades mounted on the edge of a conductor rotor. When the conductor rotor rotates, the heat dissipating blades generate an air flow for heat dissipation. However, the conventional heat sink has no design to reduce noise, and the heat dissipation effect needs to be strengthened. Therefore, reducing the noise generated when the coupling rotates and increasing the heat dissipation effect have become problems that the relevant industry players are eager to solve.

有鑑於此，本創作人係極力加以研究創作，而終於研發完成本新型之一種具低噪音散熱片的永磁傳動器結構。In view of this, the creator has tried his best to research and create, and finally developed a new type of permanent magnet actuator structure with low noise fins.
