技術簡介

市場上應用於冷凝風扇馬達，主要以定頻的內轉子馬達為主，效率只有60％。若改以外轉子馬達，效率約可達到85％，能有效節電。冷凝風機應用是處於戶外、高溫等環境，需要防水防塵的要求，若散熱不良，容易造成線圈或磁鐵溫度過高，導致毀損。 因此，本專利提出外轉子馬達散熱架構設計，來解決目前所遇到之技術瓶頸。將考量到防水防塵及散熱兩部分需求，進行了防水防塵設計，於此馬達外殼以三件式進行設計，包含：定子固定件、中圈及上蓋，此以模組化配合，達到低成本製造。於散熱設計則以定子固定件與馬達下蓋成一件式，以達到熱傳導功效。

Abstract

The fixed frequency internal rotor motor has an efficiency of only 60％, which is applied to the condensing fan motor. If the external rotor motor is used instead, the efficiency can reach about 85％, which can effectively save electricity. Condensing fan units are used in outdoor and high-temperature environments, so they need to be waterproof and dustproof. If the heat dissipation is not good, the temperature of the coil or magnet may be too high, resulting in damage. Therefore, this patent proposes the heat dissipation structure design of the external rotor motor to solve the current technical bottleneck. At the same time, waterproof, dustproof and heat dissipation are considered, the motor casing is designed in three parts, including: stator fixing parts, middle ring and upper cover, which are modularized to achieve low-cost manufacturing. In the heat dissipation design, the stator fixing part and the lower motor cover are integrated into one assembly to achieve heat conduction.
