Musiyano wekushanda kwemota 1: kumhanya/torque/saizi
Kune mhando dzakasiyana-siyana dzemota pasi rose. Mota hombe nemota diki. Mota inofamba ichidzokera shure panzvimbo pekutenderera. Mota isinganyatsoonekwe kuti sei ichidhura kudaro. Zvisinei, mota dzese dzinosarudzwa nechikonzero. Saka mota yako yaunoda inofanira kuva nerudzii rwemota, mashandiro kana hunhu hupi?
Chinangwa chenyaya iyi ndechekupa ruzivo rwekuti ungasarudza sei mota yakakodzera. Tinovimba kuti zvichabatsira kana ukasarudza mota. Uye, tinovimba kuti zvichabatsira vanhu kudzidza zvekutanga zvemota.
Kusiyana kwekushanda kuchatsanangurwa kuchakamurwa kuita zvikamu zviviri zvakasiyana seizvi:

1. Zvinotarisirwa nemota: kufamba kwekutenderera
Mota inowanzoreva mota inowana simba remakanika kubva kusimba remagetsi, uye kazhinji inoreva mota inowana kufamba kwekutenderera. (Panewo mota ine mutsara inofamba yakatwasuka, asi tichaisiya panguva ino.)
Saka, unoda kutenderera kwerudzii? Unoda kuti itenderere nesimba sechibhora, kana kuti unoda kuti itenderere zvisina simba asi ichimhanya zvakanyanya sefeni yemagetsi? Nekutarisa pamusiyano wekufamba kwekutenderera kwaunoda, hunhu hwese hwekumhanya kwekutenderera netorque hunova hwakakosha.
2. Torque
Torque isimba rekutenderera. Chiyero chetorque iN·m, asi kana iri mota diki, mN·m ndiyo inowanzoshandiswa.
Mota iyi yakagadzirwa nenzira dzakasiyana-siyana kuti iwedzere torque. Kana waya yemagetsi ichitenderera zvakanyanya, torque yacho inowedzerawo.
Nekuti huwandu hwekumonera hunogumira pahukuru hwema coil akagadzika, waya ine enamelled ine dhayamita yakakura inoshandiswa.
Mota dzedu dzemhando ye "brushless motor series" (TEC) dzine 16 mm, 20 mm, 22 mm, 24 mm, 28 mm, 36 mm, 42 mm, idzo mhando sere dzine saizi yedhayamita yekunze ye60 mm. Sezvo saizi ye "coil" ichikwirawo nedhayamita yemota, torque yakakwira inogona kuwanikwa.
Magineti ane simba anoshandiswa kugadzira ma torque makuru pasina kuchinja saizi yemota. Magineti eNeodymium ndiwo magineti ane simba rekugara kwenguva refu, achiteverwa nemagineti esamarium-cobalt. Zvisinei, kunyangwe ukangoshandisa magineti akasimba chete, simba remagineti rinobuda mumota, uye simba remagineti rinobuda harizobatsiri pakuita kuti torque ibude.
Kuti zvinyatsobatsira simba remagineti, chinhu chitete chinoshanda chinonzi electromagnetic steel plate chinoiswa laminated kuti chigone kusimudzira magnetic circuit.
Uyezve, nekuti simba remagineti remagineti esamarium cobalt rakagadzikana kana tembiricha yachinja, kushandiswa kwemagineti esamarium cobalt kunogona kutyaira mota zvakanaka munzvimbo ine tembiricha yakakura kana tembiricha yakakwira.
3. Kumhanya (kuchinja-chinja)
Huwandu hwekutenderera kwemota hunowanzonzi "speed". Ndiko kushanda kwekuti mota inotenderera kangani panguva imwe neimwe. Kunyangwe "rpm" ichiwanzo shandiswa semarevolutions paminiti, inoratidzwawo se "min-1" muSI system yemayuniti.
Zvichienzaniswa ne torque, kuwedzera huwandu hwema revolutions hakusi kwakaoma tekinoroji. Ingoderedza huwandu hwema turns mu coil kuti uwedzere huwandu hwema turns. Zvisinei, sezvo torque ichidzikira sezvo huwandu hwema revolutions huchiwedzera, zvakakosha kusangana nezvinodiwa zve torque ne revolution.
Pamusoro pezvo, kana ukashandisa mota inomhanya zvakanyanya, zvakanaka kushandisa mabhora ekufambisa kwete mabhora ekufambisa. Kana mota ichifamba zvakanyanya, kurasikirwa nekukakavadzana kunowedzera, uye hupenyu hwemota hupfupi.
Zvichienderana nekururama kweshaft, kumhanya kwakakwira, matambudziko ane chekuita neruzha nekudengenyeka anowedzera. Nekuti mota isina brush haina brush kana commutator, inoita ruzha nekudengenyeka kushoma pane mota yakakweshwa (iyo inoita kuti brush ibatane ne rotating commutator).
Danho rechitatu: Saizi
Kana zvasvika kune injini yakakodzera, saizi yemota ndeimwe yezvinhu zvakakosha pakushanda kwayo. Kunyangwe kumhanya (revolutions) uye torque zvakakwana, hazvina basa kana isingakwanise kuiswa pachigadzirwa chekupedzisira.
Kana uchida kungowedzera kumhanya, unogona kuderedza huwandu hwekutenderera kwewaya, kunyangwe huwandu hwekutenderera huri hudiki, asi kunze kwekunge paine torque shoma, haizotenderere. Saka, zvakakosha kutsvaga nzira dzekuwedzera torque.
Pamusoro pekushandisa magineti akasimba ari pamusoro apa, zvakakoshawo kuwedzera duty cycle factor yekumonera. Tave tichitaura nezvekuderedza huwandu hwekumonera waya kuti tive nechokwadi chekuti pane ma revolutions akawanda, asi izvi hazvirevi kuti waya yacho yakamonera zvisina kusimba.
Nekushandisa waya dzakakora pachinzvimbo chekuderedza huwandu hwemawindings, huwandu hwakawanda hwemagetsi hunogona kuyerera uye torque yakakwira inogona kuwanikwa kunyangwe nekumhanya kumwe chete. Spatial coefficient chiratidzo chekuti waya yakasungirirwa zvakasimba sei. Ingave iri kuwedzera huwandu hwematenderedzwa akatetepa kana kuderedza huwandu hwematenderedzwa akakora, chinhu chakakosha pakuwana torque.
Kazhinji, kubuda kwemota kunoenderana nezvinhu zviviri: simbi (magineti) uye mhangura (kutenderera).
