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.
