Dc mota drive mode.Dc drive senzira yakachipa yekutyaira yagara ichishandiswa zvakanyanya mumidziyo yemagetsi.Dc system pachayo ine zvimwe zvakakanganisika mukuita, kugadzirisa uye zvichingodaro.Mota dzemagetsi pamberi pe1990s dzakange dzave kutotyairwa nedc motors.Dc mota pachayo ine yakaderera kushanda zvakanaka, vhoriyamu hombe uye kuwanda, commutator uye kabhoni brashi inodzikamisa kuvandudzwa kwekumhanya kwayo, kumhanya kwakanyanya kwe6000 ~ 8000r/min.
Mota yemagetsi inogadzirwa nechiitiko cheiyo coil ine simba inotenderera nechisimba mundima yemagineti.Kuenzaniswa neiyo DC mota, iyo AC mota yeforklift ine isingaenzaniswi yakanakisa kuita.Vagadziri vanotevera forklift vanotsanangura maitiro e AC mota uye DC mota.Injini ye AC inonyanya kuve nemagetsi emagetsi anomonereka kana akagoverwa stator mhepo yekugadzira magineti uye inotenderera armature kana rotor.Hapana guruva rinogadzirwa mushure mekupfeka kabhoni brashi, yakachena yemukati nharaunda, inovandudza hupenyu hwesevhisi yemota.Ac motor kushanda zvakanaka kwakakwira, uye hapana utsi, kunhuwa, kusasvibisa nharaunda, ruzha idiki.Nekuda kweakatevedzana mabhenefiti, anoshandiswa zvakanyanya mukugadzirwa kwemaindasitiri uye zvekurima, zvekufambisa, kudzivirira kwenyika, zvekutengesa uye zvemumba midziyo yemagetsi yekurapa uye zvimwe zvinhu.
Induction mota AC drive system tekinoroji nyowani yakagadziriswa muma1990's.Mukana wakatanhamara weac motors nderekuti iwo haana kabhoni mabhurashi, uye haana iwo akakwira zvino zvisingakwanisi izvo dc motors inowanzove nazvo, zvinoreva kuti mukuita vanogona kuwana simba rakawanda uye rakawanda braking torque, saka vanogona kumhanya nekukurumidza.Kupisa kweiyo AC mota kunonyanya kuitika mune stator coil yemota shell, iyo yakanakira kutonhora uye kutonhora.Naizvozvo, ac motors inoda zvakanyanya mashoma zvikamu pane DC motors, hapana kupfeka zvikamu zvinoda kutsiviwa nguva dzose, zvinenge zvisina kugadzirisa, zvakanyanya kushanda, zvakanyanya kugara.
Dc mota imota inoshandura yakananga simba razvino kuita magetsi emagetsi.Nekuda kwekunaka kwayo kumhanyisa kuita, inoshandiswa zvakanyanya mukutyaira kwemagetsi.Dc mota zvinoenderana neiyo excitation modhi yakakamurwa kuita magineti echigarire, mamwe anonakidza uye anozvifarira ega mapoka matatu.Carbon brush kupfeka inoburitsa huruva, iyo inokanganisa zvakananga hupenyu hwesevhisi yemota.Iyo mota haina kuvharirwa zvizere chimiro, kupisa kunogadzirwa mumotokari panguva yebasa, kupisa kwekupisa mhedzisiro haina kusimba, haigone kumota kwenguva yakareba.Energy backflush kunyatsoshanda pabhureki iri pasi pe15%.DC mota ine chimiro chakaomarara uye yakakwira mutengo wekugadzira;Dambudziko rekugadzirisa, uye dc magetsi ekupa, mari yekuchengetedza yakakwira.Inowanzo shandiswa kutanga pasi pemutoro unorema kana kuti inoda kugadziridzwa yunifomu yemuchina wekumhanyisa, senge hombe inodzoreredza inotenderedza chigayo, winch, magetsi locomotive, trolley, nezvimwewo, inofambiswa nedc mota.
Mumakore achangopfuura, nekufambira mberi kweac induction motor variable frequency tekinoroji, uye yakakwirira simba semiconductor zvishandiso uye microprocessor kumhanya, yakagadziridzwa ac induction mota drive system ichienzaniswa nedc mota drive system, ine hunyanzvi hwepamusoro, vhoriyamu diki, yakaderera mhando, chimiro chakareruka, kuchengetedza mahara, nyore kutonhora uye zvakanakira zvehupenyu hurefu hwebasa.Iyo yekumhanyisa huwandu hweiyo system yakafara, uye inogona kuona yakaderera kumhanya inogara torque uye yakanyanya kumhanya inogara ichishanda simba, iyo inogona kunyatso kuenderana nekumhanya hunhu hunodiwa nekutyaira chaiko kwemotokari dzemagetsi.Zvinogona kutaurwa kuti ndiko kukurumidza kufambira mberi kweiyo semiconductor tekinoroji inobereka shanduko yetekinoroji yeA AC mota uye inosimudzira zvakanyanya kugona kwekutonga kwe AC mota.Uyezve, nekuramba kuderera kwemutengo wezvigadzirwa zvemagetsi, mutengo weac motor controller Hardware unogona kuderedzwa, nekudaro nekuisa hwaro hwekusimudzirwa kukuru uye kushandiswa kweAC drive system, kugadzira mamiriro.
