Mukugadzirwa kwemazuva ano kwemaindasitiri, mota dzemagetsi dzinoshandiswa zvakanyanya.Mhando dzakasiyana-siyana, mafomu emagetsi uye mazinga emagetsi emagetsi emagetsi anobuda asingagumi.Izvi zvinotevera tsanangudzo pfupi yezvikonzero zvekushanda kwechikamu chimwe chete uye matanho ekudzivirira.
Classification of motors
Mota dzemagetsi dzinogona kukamurwa kuita DC mota, asynchronous mota uye synchronous motors zvinoenderana neakasiyana zvimiro uye misimboti yekushanda.Synchronous motors inogona zvakare kukamurwa kuita magineti echigarire synchronous motors, kusada synchronous mota uye hysteresis synchronous motors.Asynchronous motors inogona kukamurwa kuita induction motors uye AC commutator mota.Induction motors inokamurwa kuita matatu-chikamu asynchronous mota, imwe-chikamu asynchronous mota uye shaded pole asynchronous motors.AC commutator motors inopatsanurwa kuita imwe-chikamu chinoteedzera mota,AC uye DC mbiri-chinangwa mota uye repulsion mota.
Njodzi dzinokonzerwa ne-single-phase kushanda kwematatu-phase asynchronous motors
Matatu-chikamu asynchronous motors ane nzira mbiri dze wiring: Y-mhando uye Δ-mhando.Kana Y-yakabatana mota ichishanda muchikamu chimwe chete, ikozvino muchikamu chakabviswa ndeye zero.The phase currents yezvimwe zvikamu zviviri zvinova mitsetse mitsetse.Panguva imwecheteyo, ichakonzera zero point drift uye chikamu chayo chemagetsi chichawedzerawo.
Kana iyo mota ine Δ-type wiring ikabviswa mukati, mota inoshanduka kuita V-mhando wiring pasi pechiito chemagetsi matatu-chikamu, uye maviri-chikamu ikozvino inowedzera ne 1.5 nguva.Kana iyo mota ine Δ-type wiring yakabviswa kunze, yakaenzana ne-ma-phase-phase windings iri kubatanidzwa munhevedzano uye boka rechitatu remamhepo richibatanidzwa mukufanana pakati pemitsara miviri.Ikozvino mune maviriwindingsyakabatanidzwa munhevedzano inoramba isina kuchinjwa.Ikozvino yekuwedzera yeboka rechitatu ichawedzerwa ne 1.5 nguva.
Kupfupisa, kana mota ikashanda muchikamu chimwe chete, iko kupeta kwayo kunowedzera nekukurumidza, uye mhepo inomonereka uye simbi casing inopisa nekukurumidza, ichipisa iyo yekuvharisa inovhara uye yobva yapisa mota inomonereka, inokanganisa mabasa akajairwa ekugadzira.Kana iyo pa-saiti nharaunda isiri yakanaka, iyo yakapoteredza nharaunda inounganidza.Kune zvinhu zvinopisa zvinogona kukonzera moto nyore nyore uye zvinokonzera migumisiro yakakomba.
Zvikonzero zvemotokari imwe-chikamu chekushanda uye matanho ekudzivirira
1. Kana mota isingakwanise kutanga, pane ruzha rwekutinhira, uye goko rine tembiricha inokwira kana kumhanya kunoderera zvakanyanya panguva yekushanda, uye tembiricha inokwira inowedzera, magetsi anofanirwa kugurwa nekukasira uye chikonzero chekutadza kunofanirwa kubviswa. kuwanikwa nokungwarira.Sarudza kana mamiriro ari pamusoro apa anokonzerwa nekushaikwa kwechikamu.
2.Kana tambo yemagetsi yedunhu guru yakanyanya kutetepa kana kusangana nekukuvara kwekunze, iyo matatu-chikamu magetsi emagetsi emagetsi achaita kuti single-phase kushanda nekuda kwechikamu chekutsva kana kunze kwesimba kurova.Iyo yakachengeteka kutakura kugona kweiyo huru yemagetsi tambo yemota ndeye 1.5 kusvika 2.5 nguva yakayerwa ikozvino yemota, uye yakachengeteka kutakura kugona kweiyo tambo yemagetsi yakabatana zvakanyanya neiyo yekuisa nzira yetambo yemagetsi.Kunyanya kana iri parallel kana kupindirana nepombi yekupisa, nguva yacho inofanira kunge yakakura kudarika 50cm.Kutakura kwakachengetedzeka kwetambo yemagetsi inokwanisa kufamba kwenguva yakareba pa70°C tembiricha inokwira kazhinji inogona kutariswa nebhuku remugadziri wemagetsi.Maererano nezvakaitika kare, kutakura kwakachengeteka kwetambo dzemhangura i6A pa square millimeter, uye iyo yealuminium waya i 4A pa square millimeter.Uye zvakare, mhangura-aluminium shanduko majoini anofanirwa kushandiswa kana mhangura-aruminiyamu waya majoini, kuitira kudzivirira oxidation pakati pemhangura-aluminium zvinhu uye kukanganisa kubatana kwekudzivirira.
3.Kugadziriswa kusina kunaka kwemhepo inoshandura kana kuvhara kwekudzivirira kunogona kukonzera imwe-chikamu kushanda kwemotokari.Kana iyo air switch configuration iri diki kwazvo, inogona kunge iri nekuda kwesimba rekupa ikozvino rakakura zvakanyanya kupisa mabiko emukati emhepo switch, zvichikonzera kuti chikamu chekubata chinopikisa chakakura kwazvo, ichigadzira imwe-phase mota oparesheni.Iyo yakarongerwa ikozvino yemhepo inochinja inofanira kunge iri 1.5 kusvika 2.5 nguva yakatarwa ikozvino yemota.Mukuwedzera, panguva yekushanda kwemotokari, inofanira kutariswa kuti kushandiswa kwemhepo kuduku kuduku, kana kuti hutano hwemhepo inoshandura pachayo hunonetsa, uye mhepo yakakodzera yekushandura inofanira kutsiviwa.
4.Mutsara wekubatanidza pakati pezvikamu mubato rekutonga rinopiswa, izvo zvinogona kuita kuti motokari iite muchikamu chimwe chete.Zvikonzero zvekupisa kwetambo yekubatanidza ndezvizvi:
① Mutsetse wekubatanidza wakanyanya kutetepa, kana mota yakawandisa ikozvino inowedzera, inogona kupisa tambo yekubatanidza.② Zvibatanidza kumativi ose emutsara wekubatanidza hazvina kunaka, zvichiita kuti mutsara wekubatanidza uwedzere kupisa, nokudaro uchipisa mutsara wekubatanidza.Pane kukuvara kwemhuka diki, senge mbeva dzinokwira pakati pemitsetse miviri, zvichikonzera kupfupika kwedunhu pakati pemitsara uye kupisa kubva pamutsetse wekubatanidza.Mhinduro ndeyokuti: usati watanga kushanda kwega kwega, kabati yekutonga inofanira kuvhurwa kunyatsotarisa kana ruvara rwemutsara wega wega wekubatanidza wachinja, uye kana ganda rekudzivirira rine mavanga ekupisa.Iyo tambo yemagetsi inoshongedzerwa zvine mutsindo zvinoenderana neazvino mutoro wemota, uye chinongedzo chakabatana zvinoenderana nemaitiro ekuita.
