二與堵轉(zhuǎn)試驗相關(guān)的定義
1、最大轉(zhuǎn)矩倍數(shù)（Tm):最大轉(zhuǎn)矩Tmax與額定轉(zhuǎn)矩Tn值之比。
2、堵轉(zhuǎn)轉(zhuǎn)矩和堵轉(zhuǎn)電流：
用外力將電機(jī)轉(zhuǎn)子軸與電機(jī)外殼固定一起，然后給電機(jī)通電，此時電機(jī)根本不轉(zhuǎn)，此時電機(jī)的電流為形象地稱為“堵轉(zhuǎn)電流”，或者電機(jī)轉(zhuǎn)起來后給軸端施加制動使之停轉(zhuǎn)也可測量堵轉(zhuǎn)電流。
3、轉(zhuǎn)差率：
同步轉(zhuǎn)速(n1)與轉(zhuǎn)子轉(zhuǎn)速(n)之差稱為“轉(zhuǎn)差”
“轉(zhuǎn)差”與同步轉(zhuǎn)速(n1)之比---轉(zhuǎn)差率(s)
s=(n1-n)/n1

轉(zhuǎn)子流量計在工業(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。
