47.某三相 4 極感應電動機，採用直接啟動時啟動電流(IS)為 120A，啟動轉矩(TS)為 30 牛頓－公尺。若改為 Y–Δ 降壓啟動，則啟動電流(IS)與啟動轉矩(TS)分別為何？
(A) IS = 120A、TS = 10 牛頓－公尺
(B) IS = 40A、TS = 30 牛頓－公尺
(C) IS = 40A、TS = 10 牛頓－公尺
(D) IS = 120A、TS = 30 牛頓－公尺
(A) IS = 120A、TS = 10 牛頓－公尺
(B) IS = 40A、TS = 30 牛頓－公尺
(C) IS = 40A、TS = 10 牛頓－公尺
(D) IS = 120A、TS = 30 牛頓－公尺
