Chinhu chakanyanya kujeka cheasynchronous motors ndechekuti pane musiyano pakati peiyo chaiyo kumhanya kwemota uye kumhanya kweiyo magnetic field, ndiko kuti, pane kutsvedza; zvichienzaniswa nemamwe maparamita ekuita kwemota, kutsvedza kwemota ndiko kuri nyore kuwana, uye chero mushandisi wemota anogona kushandisa imwe yakapusa Kushanda kunoverengerwa.
Mukutaura kwemaitiro emagetsi emota, chiyero chekutsvedza chinhu chakakosha kuita parameter, iyo inotaridzwa neperesenti yekutsvedza inoenderana nekumhanya kwesynchronous. ye.Semuenzaniso, magetsi frequency 2-pole mota ine slip rate ye1.8% uye 12-pole mota ine musiyano mukuru mukutsvedza chaiko. Kana kutsvedza kwakafanana ne1.8%, kutsvedza kwe2-pole power frequency asynchronous mota iri 3000 × 1.8% = 54 rpm, kutsvedza kwe12-pole power frequency mota i500 × 1.8% = 9 rpm.Saizvozvo, kune mota dzine mapango akasiyana ane inotsvedza yakafanana, inoenderana inotsvedza ratios ichavewo yakanyatsosiyana.
Kubva pakuenzanisa kuongorora kwemafungiro ekutsvedza uye kutsvedza, kutsvedza ndiko kukosha kwakakwana, ndiko kuti, musiyano wakakwana pakati pekumhanya chaiko uye synchronous magnetic field speed, uye chikwata chinonzi rev/min; nepo kutsvedza kuri mutsauko pakati pekutsvedza uye nekumhanyisa kumhanya . muzana.
Naizvozvo, iyo synchronous kumhanya uye kumhanya chaiko kwemota kunofanirwa kuzivikanwa kana uchiverenga slip.Iko kuverenga kweiyo synchronous kumhanya kwemota kunobva pane formula n = 60f / p (apo f ndiyo yakatemerwa frequency yemota, uye p ndiyo nhamba yemapole pairs emota); saka, iyo synchronous kumhanya inoenderana neiyo simba frequency 2, 4, 6, 8, 10 uye 12 Iyo inomhanya ndeye 3000, 1500, 1000, 750, 600 uye 500 rpm.
Iyo chaiyo yekumhanyisa mota inogona kunyatsoonekwa ne tachometer, uye inoverengerwawo zvichienderana nenhamba yekuchinja paminiti.Iyo chaiyo yekumhanya yeasynchronous mota ishoma pane iyo synchronous kumhanya, uye mutsauko pakati peiyo synchronous kumhanya uye chaiyo kumhanya ndiko kutsvedza kweasynchronous mota, uye iyo unit ndeye rev/min.
Kune akawanda marudzi ematachometers, uye emagetsi tachometers ipfungwa yakajairika: inotenderera yekuyeresa yekuyeresa maturusi akagadzirwa uye akagadzirwa zvichibva pamagetsi emazuva ano tekinoroji kazhinji ane masensa uye zviratidziro, uye mamwe zvakare ane chiratidzo chekubuda uye kutonga.Yakasiyana neyakajairwa photoelectric speed yekuyera tekinoroji, iyo inductive tachometer haidi kuisa photoelectric sensor, hapana mota shaft yekuwedzera, uye inogona kushandiswa muindasitiri yepombi yemvura uye mamwe maindasitiri uko zvakaoma kuisa sensors.
