Zinthu zomwe tikambirana m'mutu uno ndi:
Kuthamanga kolondola / kusalala / moyo ndi kusungika / kutulutsa fumbi / kuchita bwino / kutentha / kugwedezeka ndi phokoso / kutulutsa mphamvu / malo ogwiritsira ntchito
1. Gyrostability ndi kulondola
Motor ikayendetsedwa pa liwiro lokhazikika, imasunga liwiro lofananira molingana ndi inertia pa liwiro lalikulu, koma imasiyana malinga ndi mawonekedwe apakati a mota pa liwiro lotsika.
Kwa ma motors opanda brushless, kukopa pakati pa mano otsetsereka ndi maginito ozungulira kumathamanga kwambiri.Komabe, pa nkhani ya galimoto yathu brushless slotless, popeza mtunda pakati pa stator pachimake ndi maginito mosalekeza mu circumference (kutanthauza kuti magnetoresistance nthawi zonse mu circumference), n`zokayikitsa kutulutsa ripples ngakhale pa voteji otsika.Liwiro.
2. Moyo, maintainability ndi fumbi m'badwo
Zinthu zofunika kwambiri poyerekeza ndi ma brushed ndi brushless motors ndi moyo, kusungika komanso kutulutsa fumbi.Chifukwa burashi ndi commutator zimalumikizana wina ndi mnzake pomwe mota ya burashi ikuzungulira, gawo lolumikizana nalo limatha chifukwa chakukangana.
Chotsatira chake, galimoto yonse iyenera kusinthidwa, ndipo fumbi chifukwa cha kuvala zinyalala limakhala vuto.Monga momwe dzinalo likusonyezera, ma motors opanda maburashi alibe maburashi, motero amakhala ndi moyo wabwinoko, osasunthika, ndipo amapanga fumbi lochepa kuposa ma motors opukutidwa.
3. Kugwedezeka ndi phokoso
Ma motors opukutidwa amatulutsa kugwedezeka ndi phokoso chifukwa cha kukangana pakati pa burashi ndi commutator, pomwe ma brushless motors samatero.Ma motors otsekemera opanda maburashi amatulutsa kugwedezeka ndi phokoso chifukwa cha torque ya slot, koma ma motors otsekeka ndi ma hollow cup motors samatero.
Dziko limene mbali ya kuzungulira kwa rotor imachoka pakati pa mphamvu yokoka imatchedwa kusalinganika.Pamene rotor yosayenerera imazungulira, kugwedezeka ndi phokoso zimapangidwira, ndipo zimawonjezeka ndi kuwonjezeka kwa liwiro la galimoto.
4. Kuchita bwino ndi kutulutsa kutentha
Chiŵerengero cha mphamvu yamakina opangira mphamvu yamagetsi ndi mphamvu yamagetsi.Zotayika zambiri zomwe sizikhala mphamvu zamakina zimakhala mphamvu zotentha, zomwe zimatenthetsa mota.Kutayika kwa injini kumaphatikizapo:
(1).Kutayika kwa mkuwa (kutayika kwa mphamvu chifukwa cha kukana kwa mphepo)
(2).Kutayika kwachitsulo (stator core hysteresis loss, eddy current loss)
(3) Kutayika kwamakina (kutayika komwe kumachitika chifukwa cha kukangana kwa ma bere ndi maburashi, ndi kuwonongeka komwe kumachitika chifukwa cha kukana kwa mpweya: kutayika kwa mphepo)
Kutayika kwa mkuwa kumatha kuchepetsedwa mwa kukulitsa waya wa enamelled kuti muchepetse kukana kwa mafunde.Komabe, ngati waya wa enamelled wapangidwa mokulirapo, ma windings adzakhala ovuta kuyika mu injini.Chifukwa chake, ndikofunikira kupanga mawonekedwe omangirira oyenerera ma mota powonjezera gawo la ntchito yozungulira (chiwerengero cha kondakitala kudera lagawo lozungulira).
Ngati ma frequency ozungulira maginito ndi apamwamba, kutayika kwachitsulo kudzawonjezeka, zomwe zikutanthauza kuti makina amagetsi omwe ali ndi liwiro lapamwamba amatulutsa kutentha kwakukulu chifukwa cha kutaya kwachitsulo.Pakutayika kwa chitsulo, kuwonongeka kwa eddy panopa kumatha kuchepetsedwa pochepetsa mbale yachitsulo.
Ponena za kuwonongeka kwamakina, ma motors opukutidwa nthawi zonse amakhala ndi zotayika zamakina chifukwa cha kukana kukangana pakati pa burashi ndi commutator, pomwe ma brushless motors alibe.Pankhani ya ma bearings, kugundana kokwanira kwa mayendedwe a mpira kumakhala kotsika poyerekeza ndi mayendedwe owoneka bwino, zomwe zimapangitsa kuti injiniyo ikhale yogwira ntchito bwino.Ma motors athu amagwiritsa ntchito mayendedwe a mpira.
Vuto la kutentha ndiloti ngakhale ntchitoyo ilibe malire pa kutentha komweko, kutentha komwe kumapangidwa ndi galimoto kudzachepetsa ntchito yake.
Kuwotcha kukawotcha, kukana (impedance) kumawonjezeka ndipo kumakhala kovuta kuti pakali pano ikuyenda, zomwe zimapangitsa kuchepa kwa torque.Komanso, injini ikatentha, mphamvu ya maginito ya maginito imachepetsedwa ndi demagnetization yamafuta.Choncho, kubadwa kwa kutentha sikungathe kunyalanyazidwa.
Chifukwa maginito a samarium-cobalt ali ndi demagnetization yaying'ono yotentha kuposa maginito a neodymium chifukwa cha kutentha, maginito a samarium-cobalt amasankhidwa m'mapulogalamu omwe kutentha kwagalimoto kumakhala kokwera.
