    當(dang)在(zai)定(ding)子(zi)繞(rao)組(zu)通(tong)上(shang)三(san)相(xiang)交(jiao)流(liu)電(dian)源(yuan)時(shi)，電(dian)動(dong)機(ji)內(nei)就(jiu)產(chan)生(sheng)了(le)一(yi)個(ge)旋(xuan)轉(zhuan)磁(ci)場(chang)
，鼠(shu)籠(long)繞(rao)組(zu)切(qie)割(ge)磁(ci)力(li)線(xian)而(er)產(chan)生(sheng)感(gan)應(ying)電(dian)流(liu)

，從(cong)而(er)使(shi)電(dian)動(dong)機(ji)旋(xuan)轉(zhuan)起(qi)來(lai)。電(dian)動(dong)機(ji)旋(xuan)轉(zhuan)之(zhi)後(hou)，其(qi)速(su)度(du)慢(man)慢(man)增(zeng)高(gao)到(dao)稍(shao)低(di)於(yu)旋(xuan)轉(zhuan)磁(ci)場(chang)的(de)轉(zhuan)速(su)，此(ci)時(shi)轉(zhuan)子(zi)磁(ci)場(chang)線(xian)圈(quan)經(jing)由(you)直(zhi)流(liu)電(dian)來(lai)激(ji)勵(li)，使(shi)轉(zhuan)子(zi)上(shang)麵(mian)形(xing)成(cheng)一(yi)定(ding)的(de)磁(ci)極(ji)，這(zhe)些(xie)磁(ci)極(ji)就(jiu)企(qi)圖(tu)跟(gen)蹤(zong)定(ding)子(zi)上(shang)的(de)旋(xuan)轉(zhuan)磁(ci)極(ji)
