電動車輪轂馬達 Electric car wheel motor

 

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.

風力發電機  Wind driven generator

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.

單相無刷馬達  Single phase brushless motor

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.

燃油泵Fuel Pump

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.

無鐵心式永磁同步線性馬達  Coreless permanent synchro linear motor

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.
