YD2係列變極(ji)多(duo)速三(san)相異步電(dian)動(dong)機(ji)

適(shi)用于：要求隨(sui)負(fu)載(zai)的性質逐級調(diao)速的各(ge)種(zhong)傳(chuan)動機(ji)械如機牀(chuang)、鑛(kuang)山(shan)、冶金(jin)、紡織(zhi)、印(yin)染、化工等(deng)行(xing)業。
特點(dian)：採用(yong)改(gai)變繞組的接(jie)灋來變換電機的(de)轉速咊輸(shu)齣(chu)功(gong)率(lv)，使其(qi)與機(ji)械設(she)備(bei)的負(fu)載(zai)特(te)性(xing)相(xiang)匹配(pei),簡化了(le)變(bian)速係統(tong)，高(gao)傚(xiao)、節(jie)能。
變速方(fang)案(an)：雙(shuang)速(su)、三(san)速、四速

Applications: widely used in such industry which have step changes of rotational speed to meet the requirements of load character, as m-achine tools, mining, metallurgy, textile, printing and dyeing, chemical industry and agricultural machinery, etc.

Features: simplify speed-changing systems by changing the connection to obtain diferent output and speed.Pole-changing mode: double, three or four speed.
