- Inverter motere
Ma inverter motors ndi ma motors omwe amagwiritsa ntchito ukadaulo wa inverter kuwongolera liwiro la mota. Tekinoloje ya inverter imagwiritsa ntchito zida zamagetsi kuti ziwongolere liwiro la mota, motero kuzindikira kuwongolera kwa liwiro la mota, mphamvu ndi magwiridwe antchito.
Makina osinthira pafupipafupi ndi "makina apadera opangira ma frequency motor + frequency converter" njira yowongolera liwiro la AC yopangidwa ndi makina apamwamba kwambiri a zida zamagalimoto, kuphatikiza uku kwalowa m'malo mwadongosolo lakale lamakina owongolera liwiro ndi pulogalamu yowongolera liwiro la DC; Ndi ukadaulo wamagetsi amagetsi, ukadaulo wa microelectronics, chitukuko chodabwitsa chogwiritsa ntchito Ndi chitukuko chodabwitsa cha ukadaulo wamagetsi amagetsi, ukadaulo wa microelectronics, kugwiritsa ntchito "ma frequency induction motor + frequency converter" ya AC liwiro mode, ndikuchita bwino komanso chuma chake, pankhani yowongolera liwiro kuti atsogolere m'malo mwa liwiro lakale lam'badwo watsopano wosintha.
Chifukwa cha inverter galimoto liwiro kulamulira ndi kulamulira pamwamba zosayerekezeka, kuti digiri ya makina zochita zokha ndi zokolola bwino kwambiri; EPS mphamvu yamagetsi monga tsogolo la chitukuko cha ukadaulo wa inverter ndipo motero ili ndi ukadaulo wake, koma chifukwa cha inverter motor system yothamanga kwambiri kapena yotsika kwambiri, liwiro lozungulira la kuyankha kwamphamvu ndi zosowa zina za thupi lalikulu la mota yamagetsi monga mphamvu yopititsa patsogolo zofunika zolimba zidzaperekedwa kwa inverter motor idzabweretsedwa ku inverter motor. Mu ma electromagnetic, kapangidwe kake, kusungunula ndi zina mwazatsopano. Tikhoza kunena kuti chifukwa chapamwamba kwa injini ya inverter mu kayendetsedwe kafupipafupi pamagetsi wamba, kulikonse komwe kusinthika kwafupipafupi kumagwiritsidwa ntchito sizovuta kuwona chithunzi cha injini ya inverter.
- Industrial Frequency Motors
Ma motor frequency motors amatanthawuza ma mota a AC omwe amayendetsedwa mwachindunji pogwiritsa ntchito ma frequency ogwiritsira ntchito (nthawi zambiri 50Hz kapena 60Hz) ngati gwero lamagetsi, ndipo nthawi zambiri amagwiritsidwa ntchito m'njira zotsika kwambiri, zothamanga kwambiri, komanso zocheperako. Ubwino wa ma motor frequency motors ndi mawonekedwe osavuta, odalirika kwambiri komanso otsika mtengo, koma choyipa ndichakuti liwiro ndi torque ndizovuta kuwongolera ndikuwongolera, ndipo kulondola kumakhala kochepa, sikuli koyenera kugwiritsa ntchito zomwe zili ndi zofunikira zowongolera bwino kwambiri.
Pakupanga kwamafakitale amakono, ndikusintha kosalekeza kwa mtundu wazinthu ndi zofunika kuchita bwino, kuchulukirachulukira kumafunikira kulondola komanso kuwongolera magwiridwe antchito, chifukwa chake inverter motor yalowa m'malo mwa ma frequency motor monga mainstream. Ma inverter motors amatha kuwongolera liwiro ndi torque ya mota kudzera pakusintha ma frequency, kukonza magwiridwe antchito komanso kulondola kwagalimoto, ndipo ndi oyenera kugwiritsa ntchito mitundu ingapo.
- Kusiyana pakati pa inverter motor ndi ma frequency motor motor
Inverter motor ndi ma frequency motor motor ndiye kusiyana kofunikira kwambiri pakati pa kusinthasintha kwamagetsi awiri, ma frequency amagetsi amagetsi amagetsi ndi ma frequency amakhala osasintha, pomwe ma voliyumu olowera ndi ma frequency a inverter motor akusintha, ndichifukwa cha izi, zomwe zimapangidwira kuti inverter motor zizikhala zovutirapo, ndipo chifukwa chake pazokhudza thupi lagalimoto, ndikofunikira kuchitapo kanthu kuti mupewe zovuta zamagalimoto.
Inverter motor imayendetsedwa ndi inverter, zotulutsa kuchokera ku inverter ndizopanda sinusoidal rectangular waveform, ma harmonics apamwamba opangidwa ndi inverter amakhudza kwambiri magwiridwe antchito agalimoto, ma harmonics apamwamba amapangitsa kugwiritsa ntchito mkuwa kwa mota, kugwiritsa ntchito mkuwa wa rotor, kugwiritsa ntchito chitsulo ndi kutayika kwina, chofunikira kwambiri ndikugwiritsa ntchito mkuwa wa rotor. Chifukwa cha kuchuluka kwa zotayika, zotsatira zachindunji ndi kukwera kwa kutentha kwa injini.
Pazifukwa zomwe tafotokozazi, inverter motor yokhotakhota kapangidwe kanyumba poyerekeza ndi ma frequency motor padzakhala kusiyana kwina: inverter motor insulation level iyenera kukhala yopitilira mulingo umodzi kuposa ma mota wamba, monga ma frequency motors ambiri a B level insulation, and inverter motors osachepera molingana ndi F level insulation design, kuwonjezera pa kusiyana pakati pa zida zotchinjiriza, zogwirizana ndi mzere wa electromagnetic zidzakhalanso ndi kusiyana:
(1) Ma waya osagwira kutentha kwa ma electromagnetic ma mota a inverter motors akuyenera kufananizidwa ndi ma inverter omwe amapangidwira, ndikusankhidwa molingana ndi kalasi yosachepera 155.
(2) Waya wamagetsi wamagetsi opangira ma inverter uyenera kusankhidwa ngati waya wapadera wamagetsi, kusiyana pakati pa waya wamtundu uwu wamagetsi ndi waya wamba wamagetsi kumakhala pamtundu wa varnish wotsekera, womwe ungapewe kutulutsa komanso vuto la kutentha kwa sing'anga yotchinga, yomwe imatha kutsimikizira kugwira ntchito kotetezeka kwa ma motors otalikitsa moyo komanso moyo wautali wautumiki wa injini.
Mukugwiritsa ntchito kwenikweni, ena opanga ma mota mu inverter motor yokhotakhota yokhala ndi waya wandiweyani wa varnish yamagetsi, amatha kuchepetsa vuto lomwe limayambitsa, koma sangathe kuthetsa vutoli. Chifukwa chake, kuchokera pakuwunika zofunikira za injini ya inverter, kugwiritsa ntchito waya wapadera wa inverter electromagnetic, kumatha kuthetsa kukana kutentha ndikuletsa kuchitika kwamavuto a corona.
