采用星(xing)(xing)三角(jiao)(jiao)(jiao)(jiao)起(qi)(qi)(qi)(qi)動(dong)(dong)(dong)時，起(qi)(qi)(qi)(qi)動(dong)(dong)(dong)電流(liu)只是原來按三角(jiao)(jiao)(jiao)(jiao)形接(jie)法直(zhi)接(jie)起(qi)(qi)(qi)(qi)動(dong)(dong)(dong)時的1/3。如(ru)果(guo)直(zhi)接(jie)起(qi)(qi)(qi)(qi)動(dong)(dong)(dong)時的起(qi)(qi)(qi)(qi)動(dong)(dong)(dong)電流(liu)以6—7Ie計(ji)，則(ze)在星(xing)(xing)三角(jiao)(jiao)(jiao)(jiao)起(qi)(qi)(qi)(qi)動(dong)(dong)(dong)時，起(qi)(qi)(qi)(qi)動(dong)(dong)(dong)電流(liu)才2—2.3倍。這(zhe)就(jiu)是說采用星(xing)(xing)三角(jiao)(jiao)(jiao)(jiao)起(qi)(qi)(qi)(qi)動(dong)(dong)(dong)時，起(qi)(qi)(qi)(qi)動(dong)(dong)(dong)轉矩也降為原來按三角(jiao)(jiao)(jiao)(jiao)形接(jie)法直(zhi)接(jie)起(qi)(qi)(qi)(qi)動(dong)(dong)(dong)時的1/3。適用于(yu)無(wu)載(zai)或者(zhe)輕(qing)載(zai)起(qi)(qi)(qi)(qi)動(dong)(dong)(dong)的場(chang)合。并且同(tong)任(ren)何別的減(jian)壓(ya)起(qi)(qi)(qi)(qi)動(dong)(dong)(dong)器相比較(jiao)，由于(yu)其結(jie)構簡單，價格(ge)也。星(xing)(xing)三角(jiao)(jiao)(jiao)(jiao)起(qi)(qi)(qi)(qi)動(dong)(dong)(dong)方式還有(you)一個優點，即(ji)當負(fu)載(zai)較(jiao)輕(qing)時，可以讓電動(dong)(dong)(dong)機在星(xing)(xing)形接(jie)法下(xia)運行。此時，額定轉矩與負(fu)載(zai)可以匹配(pei)，這(zhe)樣(yang)能(neng)使電動(dong)(dong)(dong)機的效率有(you)所提(ti)高，并因之(zhi)節約(yue)了電力消耗。
