140DAI75300B法適用于不大于400KW的異步電動(dòng)機(jī),由于B法準(zhǔn)確度最高,是推薦的好方法。B法采用的是使用轉(zhuǎn)矩測量裝置,根據(jù)測試結(jié)果求取負(fù)載雜散耗損耗值,實(shí)現(xiàn)B法的關(guān)鍵是具備符合要求的輸出機(jī)械功率儀器、負(fù)載設(shè)備、及輸入測量儀表。
三三相異步電動(dòng)機(jī)效率確定之C法——成對電機(jī)雙電源對拖回饋試驗(yàn)損耗分析法

轉(zhuǎn)子流量計(jì)在工業(yè)生產(chǎn)過程中應(yīng)用較廣,可以測量多種介質(zhì)的流量,特別適用于中小管徑和低雷諾數(shù)的中小流量測量。轉(zhuǎn)子流量計(jì)結(jié)構(gòu)簡單,靈敏度高,量程比寬(10:1),壓力損失小且恒定,對直管段的要求不高,刻度近似線性,價(jià)格便宜,使用維護(hù)簡便。但儀表受被測介質(zhì)密度、粘度、溫度、壓力等因素的影響,其精度一般在1.5級左右。
有兩臺(tái)完全相同的成對電機(jī)可用時(shí),可用C法確定電機(jī)的效率。將兩臺(tái)電機(jī)耦合接在一起。電氣上接在兩個(gè)電源上,其中一個(gè)可調(diào)(電壓、頻率)電源。兩個(gè)電源都必須符合國標(biāo)要求,必須既能輸出功率又能吸收功率。
四三相異步電動(dòng)機(jī)效率確定之E法或E1法——測量輸入功率的損耗分析法
測量定子輸入功率,從輸入功率中減去總損耗即為輸出功率。總損耗等于規(guī)定溫度下定子I2R損耗、鐵耗、風(fēng)摩耗及負(fù)載雜散耗之和。
