Kusarudza Mota Yakakodzera: Nheyo dzeTorque, Speed, uye Saizi

Kune mhando dzakasiyana dzemota isina corepasi rose. Mota hombe nemota diki. Rudzi rwemota inogona kufamba ichidzokera shure isina kutenderera. Pakutanga, hazvizivikanwe kuti sei ichidhura kudaro. Zvisinei, pane chikonzero chekusarudza marudzi ese emota isina coreSaka, ndeapi marudzi emota, mashandiro, kana hunhu hunodiwa kuti mota yemagetsi ive yakakodzera?

Chinangwa chenyaya iyi ndechekupa ruzivo rwekuti ungasarudza sei injini yakakodzera. Tinovimba kuti zvichabatsira kana ukasarudza injini. Tinovimba kuti zvinogona kubatsira vanhu kudzidza ruzivo rwekutanga rwemainjini.

1. Torque

Torque isimba rinoita kuti zvinhu zvitenderere.mota isina coreZvakagadzirwa nenzira dzakasiyana-siyana kuti zviwedzere torque. Kutenderera kwakawanda kwewaya yemagetsi, ndiko kukura kwetorque. Nekuda kwemiganhu yehukuru hwema coils akagadzika, waya ine enamel ine dhayamita hombe inoshandiswa. Mota dzedu dzemabhurashi dzisina brushless dzinosanganisira saizi dzine dhayamita yekunze ye16mm, 20mm, 22mm, 24mm, 28mm, 36mm, 42mm, uye 50mm. Sezvo saizi ye coil ichikwirawo nedhayamita yemota, torque yakakwira inogona kuwanikwa.

Magineti akasimba anoshandiswa kugadzira torque yakakura pasina kuchinja saizi yemota. Magineti epasi rare ndiwo magineti ane simba rekugara kwenguva refu, achiteverwa nemagineti emagnesium cobalt. Zvisinei, kunyangwe ukangoshandisa magineti akasimba chete, magnetism inobuda mumota, uye magnetism inobuda haizowedzere torque. Kuti ushandise magnetism yakasimba zvizere, chinhu chitete chinoshanda chinonzi electromagnetic steel plate chinoiswa laminated kuti chigone kufambisa magnetic circuit zvakanaka.

2. Kumhanya (kuchinja-chinja)

Kumhanya kwemota yemagetsi kunowanzonzi "kumhanya." Ndiko kushanda kwekuti mota inotenderera kangani payuniti yenguva. Zvichienzaniswa ne torque, kuwedzera huwandu hwekutenderera hakusi kwakaoma tekinoroji. Ingoderedza huwandu hwekutenderera mu coil kuti uwedzere huwandu hwekutenderera. Zvisinei, sezvo torque ichiderera sezvo huwandu hwekutenderera huchiwedzera, zvakakosha kusangana nezvinodiwa zve torque nekumhanya kwekutenderera.

Pamusoro pezvo, kana ikashandiswa nekumhanya kwakanyanya, zvakanaka kushandisa mabhora ekufambisa panzvimbo pemabheya akajairika. Kumhanya kwacho kwakanyanya, kurasikirwa nekukakavadzana kunowedzera, uye hupenyu hwemota hupfupi. Zvichienderana nekunyatsorongeka kweshaft, kumhanya kwacho kwakanyanya, matambudziko ane chekuita neruzha nekudengenyeka anowedzera. Sezvo mamota asina mabhurashi asina mabhurashi kana macommutator, anogadzira ruzha nekudengenyeka kushoma pane mamota ane mabhurashi (anoita kuti mabhurashi abatane necommutator inotenderera).

3. Saizi

Kana tichitaura nezvemota yemagetsi yakakodzera, saizi yemota ndeimwe yezvinhu zvakakosha pakushanda kwayo. Kunyangwe kumhanya (kutenderera) uye torque zvakakwana, hazvina zvazvinoreva kana isingakwanise kuiswa muchigadzirwa chekupedzisira.

Kana uchida kungowedzera kumhanya, unogona kuderedza huwandu hwekutenderera kwewaya. Kunyangwe huwandu hwekutenderera huri hudiki, hahuzotenderere kunze kwekunge paine torque shoma. Saka, zvakakosha kutsvaga nzira dzekuwedzera torque.

Pamusoro pekushandisa magineti akasimba ataurwa pamusoro apa, kuwedzera duty cycle yemawindings kwakakoshawo. Tave tichikurukura nezvekuderedza huwandu hwemawindings kuti tive nechokwadi chekuti maturns acho apera, asi izvi hazvirevi kuti waya yacho yakasungirirwa zvisina kusimba.

Kutsiva kudzikiswa kwehuwandu hwemawindings newaya dzakakora kunogonawo kuita kuti magetsi awedzere uye torque yakakwira nekumhanya kumwe chete. Chinhu chemuchadenga chinoratidza kuti waya yacho yakasungirirwa zvakasimba sei. Ingave iri kuwedzera huwandu hwematenderedzwa akatetepa kana kuderedza huwandu hwematenderedzwa akakora, chinhu chakakosha pakuwana torque.
