E法與E1法的唯一區(qū)別是，E法是通過(guò)試驗(yàn)確定負(fù)載雜散耗，而E1法是按推薦值確定負(fù)載雜散耗。
五三相異步電動(dòng)機(jī)效率確定之F法或F1法——等值電路法
　　F法適用于中、大型電動(dòng)機(jī)。如不能進(jìn)行負(fù)載試驗(yàn)，可依據(jù)等值電路求取電機(jī)的運(yùn)行特性（效率、功率因數(shù)、轉(zhuǎn)速等）。
　　F法與F1法的唯一區(qū)別是，F(xiàn)法是通過(guò)試驗(yàn)確定負(fù)載雜散耗，而F1法是按推薦值確定負(fù)載雜散耗。
六三相異步電動(dòng)機(jī)效率確定之H法——圓圖法

　　轉(zhuǎn)子流量計(jì)在工業(yè)生產(chǎn)過(guò)程中應(yīng)用較廣，可以測(cè)量多種介質(zhì)的流量，特別適用于中小管徑和低雷諾數(shù)的中小流量測(cè)量。轉(zhuǎn)子流量計(jì)結(jié)構(gòu)簡(jiǎn)單，靈敏度高，量程比寬（10：1），壓力損失小且恒定，對(duì)直管段的要求不高，刻度近似線性，價(jià)格便宜，使用維護(hù)簡(jiǎn)便。但儀表受被測(cè)介質(zhì)密度、粘度、溫度、壓力等因素的影響，其精度一般在1．5級(jí)左右。

　　H法適用于無(wú)法進(jìn)行滿載試驗(yàn)的中、大型電動(dòng)機(jī)，H法是假設(shè)當(dāng)轉(zhuǎn)速保持恒定時(shí)，隨著電壓的降低電機(jī)的負(fù)載電流隨著電壓同比減少，功率隨電壓的平方減少。
　　這幾種效率確定的試驗(yàn)方法中，A、B準(zhǔn)確度最高，在功率較大的電機(jī)中，采用C法準(zhǔn)確度較高，其次是E、F、G法，H法準(zhǔn)確度相對(duì)較低。
