外轉式設計可採直接驅動,磁路最佳化使得馬達有高功率密度及低頓動轉矩,使馬達體積有效縮小並達到平順運轉的優點。
Outer-spin design can be driven directly. Optimized magnetic circuit makes motor has high power density and low torque moment to effectively reduce motor size and achieve smooth operation.
為達成易啟動特性,故低頓動轉矩設計是重點,且低電流密度可提升發電機壽命,外轉式轉子設計則可提升整體慣量。
In order to achieve east startup feature, low torque moment design is focused. Low current density improve service life of generator. Outer-spin rotor design improves entire inert mass.
應用於閥門控制,必須搭配特殊機構操作,並旋轉在特定角度內,應用空間小故採高功率密度設計,並使用特殊超高導磁材料。
Apply to valve control and should be operated with special mechanism to be rotated in s specific angle. High power density design is used due to small application space. Special high magnetic conduction material is used.
300V永磁無刷馬達及Sensorless驅動器設計,整合切換式電源及馬達驅動電路,有效控制產品體積及成本。
300V permanent magnet brushless motor and design of sensorless driver integrates switching power and motor driving circuit to control product size and cost effectively.
因馬達浸於燃油中,必須進行氣隙尺寸優化並將馬達特性優化,除要能有效抵抗燃油的黏滯阻力,還要讓操作電流控制在夠低的狀態。
Motor is immersed in fuel, it is necessary to optimize size of air gap and motor features to resist viscous resistance of fuel and control operation current to a low level.
為求直接驅動負載時能獲得暫態響應快及運轉平順的優勢,故反電動勢波形設計為弦波,並且將動子線圈進行有效排列,縮小佔用空間。
In order to obtain advantages of quick transient response and smooth operation when drive load directly, back-EMF wave is designed as sine wave. Moving coil is arranged effectively to reduct space occupied.
