Pali mitundu iwiri yama motors oyendetsa omwe amagwiritsidwa ntchito kwambiri pamagalimoto atsopano amphamvu: maginito okhazikika a synchronous motors ndi ma AC asynchronous motors. Magalimoto ambiri atsopano amagwiritsa ntchito maginito okhazikika a maginito, ndipo magalimoto ochepa okha ndi omwe amagwiritsa ntchito ma AC asynchronous motors.
Pakadali pano, pali mitundu iwiri yamagalimoto oyendetsa omwe amagwiritsidwa ntchito kwambiri pamagalimoto atsopano amphamvu: maginito okhazikika a ma synchronous motors ndi ma AC asynchronous motors. Magalimoto ambiri atsopano amagwiritsa ntchito maginito okhazikika a maginito, ndipo magalimoto ochepa okha ndi omwe amagwiritsa ntchito ma AC asynchronous motors.
Mfundo yogwira ntchito ya injini yokhazikika ya maginito synchronous:
Kupatsa mphamvu kwa stator ndi rotor kumapanga mphamvu ya maginito yozungulira, kuchititsa kuyenda kwapakati pakati pa ziwirizi. Kuti rotor idutse mizere ya maginito ndikupanga maginito, liwiro lozungulira liyenera kukhala pang'onopang'ono kuposa liwiro lozungulira la maginito a stator. Popeza awiriwa nthawi zonse amayenda mosiyanasiyana, amatchedwa asynchronous motors.
Mfundo yogwira ntchito ya AC asynchronous motor:
Kupatsa mphamvu kwa stator ndi rotor kumapanga mphamvu ya maginito yozungulira, kuchititsa kuyenda kwapakati pakati pa ziwirizi. Kuti rotor idutse mizere ya maginito ndikupanga maginito, liwiro lozungulira liyenera kukhala pang'onopang'ono kuposa liwiro lozungulira la maginito a stator. Popeza awiriwa nthawi zonse amayenda mosiyanasiyana, amatchedwa asynchronous motors. Popeza palibe kugwirizana kwamakina pakati pa stator ndi rotor, sizosavuta kupanga komanso kupepuka kulemera kwake, komanso kudalirika kwambiri pakugwira ntchito komanso kumakhala ndi mphamvu zambiri kuposa ma mota a DC.
Maginito osatha a ma synchronous motors ndi ma asynchronous motors a AC aliyense ali ndi zabwino ndi zoyipa zake pamagwiritsidwe osiyanasiyana. Zotsatirazi ndi kufananitsa kofala:
1. Kuchita bwino: Kuchita bwino kwa injini yokhazikika ya maginito nthawi zambiri kumakhala kokwera kuposa injini ya AC asynchronous motor chifukwa simafunikira maginito kuti apange mphamvu yamaginito. Izi zikutanthauza kuti pansi pa mphamvu yomweyo, injini yokhazikika ya maginito synchronous imadya mphamvu zochepa ndipo imatha kupereka maulendo ataliatali.
2. Kuchuluka kwa mphamvu: Mphamvu yamagetsi yamagetsi okhazikika a synchronous motor nthawi zambiri imakhala yapamwamba kuposa ya AC asynchronous motor chifukwa rotor yake simafuna ma windings ndipo motero imatha kukhala yaying'ono. Izi zimapangitsa maginito okhazikika a ma synchronous motors kukhala opindulitsa pakugwiritsa ntchito malo ocheperako monga magalimoto amagetsi ndi ma drones.
3. Mtengo: Mtengo wa AC asynchronous motors nthawi zambiri umakhala wotsika kuposa maginito okhazikika a synchronous motors chifukwa mawonekedwe ake ozungulira ndi osavuta ndipo safuna maginito osatha. Izi zimapangitsa ma mota a AC asynchronous kukhala opindulitsa pazinthu zina zotsika mtengo, monga zida zapakhomo ndi zida zamafakitale.
4. Kuwongolera zovuta: Kuwongolera kwamphamvu kwa maginito okhazikika a ma synchronous motors nthawi zambiri kumakhala apamwamba kuposa a AC asynchronous motors chifukwa kumafuna kuwongolera kolondola kwa maginito kuti akwaniritse bwino kwambiri komanso kusasunthika kwamphamvu kwambiri. Izi zimafuna ma aligorivimu ovuta kuwongolera ndi zamagetsi, kotero muzinthu zina zosavuta ma mota a AC asynchronous amatha kukhala oyenera.
Mwachidule, maginito okhazikika a ma synchronous motors ndi ma asynchronous motors a AC aliyense ali ndi zabwino ndi zovuta zake, ndipo amayenera kusankhidwa molingana ndi mawonekedwe ndi zosowa zawo. Pochita bwino kwambiri komanso kugwiritsa ntchito mphamvu zambiri monga magalimoto amagetsi, maginito okhazikika a synchronous motors nthawi zambiri amakhala opindulitsa; pomwe mumapulogalamu ena otsika mtengo, ma mota a AC asynchronous amatha kukhala oyenera.
Zolakwika zodziwika bwino zama motors oyendetsa magalimoto atsopano ndi awa:
- Kulakwitsa kwa insulation: Mutha kugwiritsa ntchito mita yotsekera kuti musinthe mpaka 500 volts ndikuyesa magawo atatu a motor uvw. Mtengo wabwinobwino wa kutchinjiriza ndi pakati pa 550 megohms ndi infinity.
- Mizere yong'ambika: Mota imang'ung'udza, koma galimotoyo sinayankhe. Gwirani injini kuti muwone kuchuluka kwa mavalidwe pakati pa mano a spline ndi mano amchira.
- Kutentha kwambiri kwa mota: kugawidwa m'magawo awiri. Choyamba ndi kutentha kwenikweni kwenikweni komwe kumachitika chifukwa cha kupopera madzi kusagwira ntchito kapena kusowa kwa choziziritsa. Chachiwiri chimayamba chifukwa cha kuwonongeka kwa sensor ya kutentha kwa injini, kotero ndikofunikira kugwiritsa ntchito kukana kwa multimeter kuyeza masensa awiri a kutentha.
- Kulephera kothetsa: kugawidwa m'magawo awiri. Choyamba ndi chakuti kulamulira kwamagetsi kumawonongeka ndipo mtundu uwu wa zolakwika umanenedwa. Chachiwiri ndi chifukwa cha kuwonongeka kwenikweni kwa solver. Sine, cosine ndi chisangalalo cha motor solver zimayezedwanso padera pogwiritsa ntchito zosintha za resistor. Nthawi zambiri, kukana kwa sine ndi cosine kuli pafupi kwambiri ndi 48 ohms, zomwe ndi sine ndi cosine. Kukana kosangalatsa kumasiyana ndi ma ohm angapo, ndipo chisangalalo ndi ≈ 1/2 sine. Ngati wothetsayo alephera, kukana kumasiyana kwambiri.
Ma splines a motor motor drive yamphamvu amavala ndipo amatha kukonzedwa motere:
1. Werengani angler ya injini musanakonze.
2. Gwiritsani ntchito zida kuti ziro-sinthire chosinthira musanasonkhanitse.
3. Pambuyo pokonza kutsirizidwa, sonkhanitsani galimoto ndi kusiyanitsa ndiyeno perekani galimotoyo. #electricdrivecyclization# #electricmotorconcept# #motorsinnovationtechnology# # motorprofessionalknowledge# # motorovercurrent# #深蓝superelectricdrive#
