1. Okulindelwe injini: ukunyakaza okujikelezayo
I-motor ngokuvamile ibhekisela kunjini ethola amandla emishini emandleni kagesi, futhi ezimweni eziningi ibhekisela enjini ethola ukunyakaza okujikelezayo.(Kukhona nenjini yomugqa enyakazayo, kodwa sizokushiya ngaphandle kulokhu.)

Ngakho, hlobo luni lokuzungezisa olufunayo?Ingabe ufuna ukuthi ijike ngamandla njenge-drill, noma ufuna ijike ibuthakathaka kodwa ngesivinini esikhulu njengesiphephetha-moya sikagesi?Ngokugxila emehlukweni wokunyakaza okufunayo, izici ezimbili zejubane lokujikeleza kanye netorque ziba zibalulekile.

2. Torque
I-torque ingamandla okujikeleza.Iyunithi ye-torque ingu-N · m, kodwa endabeni yamamotho amancane, i-mN·m ivame ukusetshenziswa.

I-motor yakhelwe ngezindlela ezahlukahlukene zokwandisa i-torque.Ukuphenduka okwengeziwe kwentambo kagesi, itorque iba nkulu.
Ngenxa yokuthi inombolo yokusonta inqunyelwe usayizi wekhoyili ongashintshi, kusetshenziswa intambo enameline enobubanzi obukhulu bentambo esetshenziswayo.
Uchungechunge lwethu lwe-brushless motor (TEC) oluno-16 mm, 20 mm no-22 mm no-24 mm, 28 mm, 36 mm, 42 mm, izinhlobo ezingu-8 zikasayizi wama-60 mm ngaphandle kobukhulu.Njengoba usayizi wekhoyili nawo ukhuphuka ngobubanzi bemoto, i-torque ephakeme ingatholakala.
Ozibuthe abanamandla basetshenziselwa ukukhiqiza ama-torque amakhulu ngaphandle kokushintsha usayizi wenjini.Ozibuthe be-Neodymium yizibuthe ezinamandla kakhulu ezihlala njalo, zilandelwa yizibuthe ze-samarium-cobalt.Kodwa-ke, noma ngabe usebenzisa omazibuthe abanamandla kuphela, amandla kazibuthe azovuza emotweni, futhi amandla kazibuthe avuzayo ngeke abe nomthelela ku-torque.
Ukuze usebenzise ngokugcwele uzibuthe oqinile, into encane esebenzayo ebizwa ngokuthi i-electromagnetic steel plate yenziwe i-laminated ukuze ithuthukise ukujikeleza kazibuthe.
Ngaphezu kwalokho, ngenxa yokuthi amandla kazibuthe kazibuthe we-samarium cobalt azinzile ekushintsheni kwezinga lokushisa, ukusetshenziswa kozibuthe be-samarium cobalt kungashayela imoto ngokuzinza endaweni enezinguquko ezinkulu zokushisa noma amazinga okushisa aphezulu.

3. Isivinini (amarevolution)
Inombolo yama-revolutions of motor ngokuvamile ibizwa ngokuthi "isivinini".Ukusebenza kokuthi injini iphenduka kangaki ngesikhathi seyunithi ngayinye.Nakuba i-"rpm" ivame ukusetshenziswa njengokuguquguquka ngomzuzu, iphinda izwakale ngokuthi "min-1" ohlelweni lwe-SI lwamayunithi.

Uma kuqhathaniswa ne-torque, ukukhulisa inani lama-revolution akunzima ngokwezobuchwepheshe.Nciphisa nje inani lokuphenduka kukhoyili ukwandisa inani lokuphenduka.Kodwa-ke, njengoba i-torque iyancipha njengoba inani lama-revolution likhula, kubalulekile ukuhlangabezana nezidingo ze-torque ne-revolution.

Ukwengeza, uma ukusetshenziswa kwesivinini esikhulu, kungcono ukusebenzisa ama-ball bearings kune-plain bearings.Lapho ijubane liphakeme, kukhulu ukulahleka kokumelana nokungqubuzana, impilo yemoto iba mfishane.
Kuye ngokunemba kwe-shaft, lapho isivinini siphezulu, kuba mkhulu izinkinga ezihlobene nomsindo nokudlidliza.Ngenxa yokuthi i-brushless motor ayinalo ibhulashi noma isihambisi, ikhiqiza umsindo omncane nokudlidliza kunenjini ebhulashiwe (okwenza ibhulashi lihlangane nomshini ojikelezayo).
Isinyathelo sesi-3: Usayizi
Uma kukhulunywa ngemoto ekahle, usayizi wemoto nawo ungenye yezinto ezibalulekile zokusebenza.Ngisho noma isivinini (ama-revolutions) kanye ne-torque kwanele, akusizi uma ingakwazi ukufakwa kumkhiqizo wokugcina.

Uma nje ufuna ukwandisa isivinini, unganciphisa inani lokuphenduka kocingo, noma ngabe inani lokujika lincane, kodwa ngaphandle uma kukhona i-torque encane, ngeke ijikeleze.Ngakho-ke, kuyadingeka ukuthola izindlela zokwandisa i-torque.

Ukwengeza ekusebenziseni omazibuthe abanamandla abangenhla, kubalulekile futhi ukwandisa isici somjikelezo wokusebenza kokusonga.Besilokhu sikhuluma ngokunciphisa inani lokusongelwa kwezintambo ukuze kuqinisekiswe inani lama-revolution, kodwa lokhu akusho ukuthi ucingo lulimele ngokuxekethile.

Ngokusebenzisa izintambo eziwugqinsi esikhundleni sokunciphisa inani lama-windings, amanani amaningi wamanje angageleza futhi i-torque ephezulu ingatholakala ngisho nangesivinini esifanayo.I-coefficient yendawo iyinkomba yokuthi ucingo luqine kangakanani.Noma ngabe kukhulisa inani lokujika okuncane noma ukunciphisa inani lokujika okujiyile, kuyisici esibalulekile ekutholeni itorque.

Ngokuvamile, ukukhishwa kwemoto kuncike ezintweni ezimbili: insimbi (umazibuthe) nethusi (i-winging).
