ao895交流電機(jī)調(diào)速方法

一、變極對(duì)數(shù)調(diào)速方法

改變定子繞組的接紅方式來(lái)改變籠型電動(dòng)機(jī)定子極對(duì)數(shù)達(dá)到調(diào)速。

二、變頻調(diào)速方法

使用變頻器改變電動(dòng)機(jī)定子電源的頻率，從而改變其同步轉(zhuǎn)速的調(diào)速方法。

三、串級(jí)調(diào)速方法

串級(jí)調(diào)速是指繞線式電動(dòng)機(jī)轉(zhuǎn)子回路中串入可調(diào)節(jié)的附加電勢(shì)來(lái)改變電動(dòng)機(jī)的轉(zhuǎn)差，達(dá)到調(diào)速的目的。大部分轉(zhuǎn)差功率被串入的附加電勢(shì)所吸收，再利用產(chǎn)生附加的裝置，把吸收的轉(zhuǎn)差功率返回電網(wǎng)或轉(zhuǎn)換能量加以利用。根據(jù)轉(zhuǎn)差功率吸收利用方式，串級(jí)調(diào)速可分為電機(jī)串級(jí)調(diào)速、機(jī)械串級(jí)調(diào)速及晶閘管串級(jí)調(diào)速形式，多采用晶閘管串級(jí)調(diào)速。
