So-called high-efficiency motors are those with reduced power consumption. A standard 10-hp motor has an efficiency of 87 %, while a high-efficiency motor's efficiency is 89.5 %. This difference reduces energy losses by a fifth.
所謂「高效率馬達」，是指比一般馬達減少能量耗損的馬達，以「10 馬」為例，一般馬達效率 87 %，高效率馬達的效率至少達 89.5 %，減少了 2 成的能量損失。
