Lin Hong-hsiang, vice chief executive of TECO's Industrial Motors and Applications Department, says that high-efficiency motors minimize energy loss inside the motor and boost drive efficiency though improvements to internal structural design, changes in coil winding techniques, and the use of high-conductivity copper rods instead of aluminum rods.
東元電機重電事業部副執行長林弘祥指出，高效率馬達是透過設計改善內部結構、改變繞線方式，或者使用導電性高的銅棒來取代鋁棒，來減少馬達內部的能量損失，提高傳動效率。
