Zinthu zomwe tikambirana m'mutu uno ndi izi:
Kulondola kwa liwiro/kusalala/kukhala ndi moyo wabwino komanso kusamalidwa bwino/kupanga fumbi/kuchita bwino/kutentha/kugwedezeka ndi phokoso/njira zotsukira utsi/malo ogwiritsira ntchito
1. Kukhazikika kwa gyrost ndi kulondola
Injini ikayendetsedwa pa liwiro lokhazikika, imasunga liwiro lofanana malinga ndi inertia pa liwiro lalikulu, koma imasiyana malinga ndi mawonekedwe apakati a injini pa liwiro lotsika.
Pa ma mota opanda maburashi olumikizidwa, kukopana pakati pa mano olumikizidwa ndi maginito ozungulira kudzagunda pa liwiro lotsika. Komabe, pankhani ya mota yathu yopanda maburashi, popeza mtunda pakati pa stator core ndi maginito ndi wokhazikika mu circumference (kutanthauza kuti magnetoresistance ndi wokhazikika mu circumference), sizingatheke kupanga ma ripples ngakhale pa voltage yotsika. Liwiro.
2. Moyo, kusamalira bwino zinthu komanso kupanga fumbi
Zinthu zofunika kwambiri poyerekeza ma mota opangidwa ndi burashi ndi opanda burashi ndi moyo, kukhazikika komanso kupanga fumbi. Chifukwa burashi ndi commutator zimakumana pamene mota wa burashi ikuzungulira, gawo lolumikizana lidzawonongeka chifukwa cha kukangana.
Motero, mota yonse iyenera kusinthidwa, ndipo fumbi chifukwa cha kuwonongeka kwa zinyalala limakhala vuto. Monga momwe dzinalo likusonyezera, mota zopanda burashi zilibe maburashi, kotero zimakhala ndi moyo wabwino, zimasamalidwa bwino, ndipo zimapanga fumbi lochepa kuposa mota zopukutidwa.
3. Kugwedezeka ndi phokoso
Ma mota opangidwa ndi burashi amatulutsa kugwedezeka ndi phokoso chifukwa cha kukangana pakati pa burashi ndi commutator, pomwe ma mota opanda burashi satero. Ma mota opanda burashi opangidwa ndi burashi amatulutsa kugwedezeka ndi phokoso chifukwa cha torque ya slot, koma ma mota opangidwa ndi ma slot ndi ma mota opanda chikho satero.
Mkhalidwe umene mzere wozungulira wa rotor umapatuka pakati pa mphamvu yokoka umatchedwa kusalinganika. Rotor yosalinganika ikazungulira, kugwedezeka ndi phokoso zimapangidwa, ndipo zimawonjezeka ndi kuwonjezeka kwa liwiro la injini.
4. Kuchita bwino komanso kupanga kutentha
Chiŵerengero cha mphamvu yamakina yotulutsa ndi mphamvu yamagetsi yolowera ndi momwe injini imagwirira ntchito. Zotayika zambiri zomwe sizimakhala mphamvu yamakina zimakhala mphamvu yotentha, zomwe zimatenthetsa injini. Zotayika za injini zikuphatikizapo:
(1). Kutayika kwa mkuwa (kutayika kwa mphamvu chifukwa cha kukana kugwedezeka)
(2). Kutayika kwa chitsulo (kutayika kwa stator core hysteresis, kutayika kwa eddy current)
(3) Kutayika kwa makina (kutayika komwe kumachitika chifukwa cha kukana kukangana kwa mabearing ndi maburashi, ndi kutayika komwe kumachitika chifukwa cha kukana mpweya: kutayika kwa kukana mphepo)
Kutayika kwa mkuwa kungachepe pokulitsa waya wa enamelled kuti achepetse kukana kwa kuzunguzika. Komabe, ngati waya wa enamelled wapangidwa kukhala wokhuthala, kuzunguzika kumakhala kovuta kuyika mu mota. Chifukwa chake, ndikofunikira kupanga kapangidwe ka kuzunguzika koyenera mota powonjezera duty cycle factor (chiŵerengero cha kondakitala kudera lozungulira la kuzunguzika).
Ngati mphamvu ya maginito yozungulira imakhala yokwera, kutayika kwa chitsulo kudzawonjezeka, zomwe zikutanthauza kuti makina amagetsi omwe ali ndi liwiro lalikulu lozungulira adzapanga kutentha kwambiri chifukwa cha kutayika kwa chitsulo. Pa kutayika kwa chitsulo, kutayika kwa eddy current kungachepe pochepetsa mbale yachitsulo yopangidwa ndi laminated.
Ponena za kutayika kwa makina, ma mota opangidwa ndi brush nthawi zonse amakhala ndi kutayika kwa makina chifukwa cha kukana kukangana pakati pa burashi ndi commutator, pomwe ma mota opanda brush alibe. Ponena za ma bearing, coefficient ya friction ya ma ball bearing ndi yotsika kuposa ya ma plain bearing, zomwe zimapangitsa kuti mota igwire bwino ntchito. Ma mota athu amagwiritsa ntchito ma ball bearing.
Vuto ndi kutentha ndilakuti ngakhale kugwiritsa ntchito kulibe malire pa kutentha komweko, kutentha komwe kumapangidwa ndi mota kumachepetsa magwiridwe ake.
Pamene kuzunguliza kwayamba kutentha, kukana (impedance) kumawonjezeka ndipo zimakhala zovuta kuti magetsi aziyenda, zomwe zimapangitsa kuti mphamvu yamagetsi ichepe. Komanso, injini ikayamba kutentha, mphamvu ya maginito ya maginito imachepa chifukwa cha kutentha kwa magetsi. Chifukwa chake, kupanga kutentha sikunganyalanyazidwe.
Chifukwa maginito a samarium-cobalt ali ndi mphamvu yochepa ya demagnetization ya kutentha kuposa maginito a neodymium chifukwa cha kutentha, maginito a samarium-cobalt amasankhidwa m'malo omwe kutentha kwa injini kuli kokwera.
