Kufambira mberi, zvichireva izvi, unogona kufunga nezvekufambira mberi kwekutora zvitupa zvehunyanzvi, seCET-4 uye CET-6.Mumota, mota inewo matanho.Iwo akatevedzana pano haarevi kureba kwemota, asi kune synchronous kumhanya kwemota.Ngatitorei nhanho 4 mota semuenzaniso kuti tione chirevo chemota dzakatevedzana.
Level 4 motokari inoreva 1-miniti synchronous speed yemotor = {frequency of power supply (50Hz) × 60 seconds} ÷ (motor stages ÷ 2) =3000 ÷ 2 = 1500 revolutions.Mufekitari, tinowanzonzwa kuti injini ndeyematanho akati wandei.Kuti tinzwisise, isu tinofanira kutanga taziva pfungwa yedanda: danda rinoreva danda remagineti rakaumbwa nejenareta rotor mushure meiyo excitation ikozvino inoshandiswa kune rotor coil.Muchidimbu, zvinoreva kuti shanduko yega yega ye rotor inogona kupinza akati wandei kutenderera kweazvino mune imwe kutendeuka kweiyo stator coil.Izvo zvinodikanwa kugadzira 50Hz inogona kana huwandu hwemapango hwakasiyana Kumhanya kwakasiyana kunodiwa.50Hz, 60 seconds nemaminetsi (kureva 3000) yakakamurwa nenhamba yemapango ndiyo nhamba yematenderedzwa emotor paminiti.Izvi zvakafanana kune mota, inongori inverse process yejenareta.
Huwandu hwemapango hunoratidza kukurumidza kwemotikari.Iyo 2-pole synchronous kumhanya i3000rmin, iyo 4-pole synchronous kumhanya i1500rmin, iyo 6-pole synchronous kumhanya i1000rmin, uye masere-pole synchronous kumhanya i750rmin.Zvinogona kunzwisiswa kuti 2-pole ndiyo nhamba yepasi (3000), 4 matanda anogona kungopatsanurwa kuita 2, 6 mapango anogona kukamurwa kuita 3, uye mapango 8 anogona kukamurwa kuita 4. Panzvimbo pematanda maviri, 3000 inofanira kushandiswa kubvisa 2. Kuwanda kwenhamba yemapango emota, inodzikira kumhanya kwemota, asi yakakura torque yayo;pakusarudza mota, iwe unofanirwa kufunga nezve yekutanga torque inodiwa nemutoro.Semuenzaniso, torque inodiwa kutanga nemutoro yakakura kupfuura iyo yekusatakura-mutoro kutanga.Kana iri yepamusoro-simba uye inorema mutoro kutanga, Iyo nhanho-pasi kutanga (kana nyeredzi delta kutanga) ichatariswa zvakare;kana iri yekumhanya inoenderana nemutoro mushure mekuona huwandu hwemapango emota, inogona kutariswa kutyaira ine bhandi pulley yedhayamita yakasiyana kana neinosiyana spidhi giya (Gearbox) Kana simba rinodiwa remutoro risingakwanisi kuzadzikiswa mushure mekuona. nhamba yemapango emota kuburikidza nebhandi kana giya rekufambisa, simba rekushandisa remota rinofanira kutariswa.
Zvitatu chikamu AC mota inonyanya kuumbwa ne stator uye rotor.Kana matatu-phase AC yakabatana kune stator, inotenderera magineti inogadzirwa.Magnetic field inogara iine mapango maviri (anogonawo kunzi anoonekwa ari maviri), anoti N pole (North Pole) neS pole (south pole) , inozivikanwawo sea counter pole.Kana iyo inotenderedza modhi ye AC mota stator mhepo ichisiyana, huwandu hwemagineti mapango einotenderera yemagineti inosiyana.Nhamba yemagineti mapango inobata zvakananga kumhanya kwemota, uye hukama hwavo ndehwe: synchronous speed = 60 × Frequency level logarithm.Kana iyo synchronous kumhanya yemota iri 1500 rpm, inogona kuverengerwa kuti pole logarithm ndeye 2, kureva, 4-pole mota zvinoenderana neformula iri pamusoro.Synchronous kumhanya uye pole logarithm ndiwo akakosha maparamita emota, ayo anogona kuwanikwa pane nameplate emota.Nekuti pole logarithm inogona kukanganisa kumhanya kwemota, kumhanya kwemota kunogona kuchinjwa nekuchinja pole logarithm yemota.
Kune mitoro yemvura yakadai semafeni nemapombi, rudzi urwu rwemutoro rune chinhu chakatanhamara.Sezvo chirevo chichienda, chinonzi kuramba mutation, zvinoreva kuti rudzi urwu rwemutoro rune kupokana kukuru kune shanduko yemamiriro ezvinhu aripo.Kunyangwe torque inodiwa kusimudzira shanduko yerudzi urwu rwemutoro haina kukwirira, inoda simba rakawanda kushandura mamiriro aripo nekukurumidza.Zvakaita semvura iri kufashaira.Moto muduku unogonawo kubika, uye inofanira kunge Ichafashaira nokukurumidza, uye moto unogona kudiwa uchava mukuru kwazvo.
Aya ndiwo tsananguro dzakananga dzemota dzakatevedzana.Kune yakapihwa frequency uye yekutanga ikozvino, hapana hukama husingadzivisike pakati pavo.Iko kutanga ikozvino kunoenderana nekumisikidzwa kwekutanga VF curve uye kureba kwekumhanyisa nguva.Zvekuremerwa kwemvura, kushandisa akawanda magetsi curve kunogona kuita kuti michina ishande yakawanda-yekuchengetedza simba uye kuwana mamwe mabhenefiti ehupfumi.
