1, AC asynchronous mota

AC asynchronous mota inotungamira AC voltage mota, inoshandiswa zvakanyanya mumafeni emagetsi, mafiriji, michina yekuwachisa, maair conditioner, hair dryer, vacuum cleaners, mahodhi emhando, madhishi, michina yekusonesa yemagetsi, michina yekugadzira chikafu nemimwe midziyo yemumba, se. pamwe chete nemidziyo yemagetsi yakasiyana-siyana uye zviduku-duku zvemagetsi.

AC asynchronous mota yakakamurwa kuita induction mota uye AC commutator mota.Induction mota yakakamurwa kuita imwe-chikamu asynchronous mota, AC / DC mota uye repulsion mota.

Kumhanya kwemota (rotor kumhanya) ishoma pane kumhanya kweiyo inotenderera magineti, saka inonzi asynchronous mota.Izvo zvakangofanana neiyo induction mota.S = (ns-n) / NS.S ndiyo mwero wekutsvedza,

NS ndiyo magineti kumhanya uye N ndiyo inomhanyisa rotor.

Basic principle:

1. Kana iyo matatu-phase asynchronous mota yakabatana neatatu-phase AC magetsi, matatu-phase stator winding inoyerera nepakati-nhatu-phase magnetomotive simba (stator inotenderera magnetomotive simba) inogadzirwa neyetatu-phase symmetrical ikozvino uye inogadzira. inotenderera yemagineti.

2. Iyo inotenderera yemagineti ine hama yekucheka mafambiro neiyo rotor conductor.Zvinoenderana nemusimboti we electromagnetic induction, iyo rotor conductor inogadzira induced electromotive simba uye induced ikozvino.

3. Zvinoenderana nemutemo wemagetsi emagetsi, ikozvino inotakura rotor conductor inobatwa nemagetsi emagetsi mune remagineti kuumba electromagnetic torque uye kutyaira rotor kutenderera.Kana paine mekiniki mutoro pamota shaft, inoburitsa simba remagetsi kunze.

Asynchronous mota imhando ye AC mota, uye chiyero chekumhanya pasi pemutoro kune kuwanda kweiyo yakabatana gidhi yemagetsi haina kugadzikana.Inoshandukawo nehukuru hwemutoro.Iyo yakakura torque yemutoro, iyo yakaderera iyo rotor kumhanya.Asynchronous mota inosanganisira induction mota, yakapetwa kaviri induction mota uye AC commutator mota.Induction mota ndiyo inonyanya kushandiswa.Inogona kunzi asynchronous mota pasina kukonzera kusanzwisisana kana kuvhiringidzika.

Iyo stator mhepo yeyakajairwa asynchronous mota yakabatana kune AC magetsi grid, uye iyo rotor mhepo haidi kubatanidzwa kune mamwe magetsi masosi.Naizvozvo, ine zvakanakira chimiro chakareruka, kugadzira kuri nyore, kushandisa uye kugadzirisa, kushanda kwakavimbika, yakaderera mhando uye mutengo wakaderera.Asynchronous mota ine yakanyanya kushanda zvakanaka uye yakanaka kushanda maitiro.Iyo inomhanya nekumhanya inogara kubva pasina-mutoro kusvika kuzere mutoro, iyo inogona kusangana nekutapurirana zvinodiwa zveakawanda maindasitiri uye ekurima ekugadzira michina.Asynchronous motors zvakare ari nyore kugadzira akasiyana edziviriro marudzi kuti asangane nezvinodiwa zvezvakasiyana mamiriro ezvakatipoteredza.Kana iyo asynchronous mota ichimhanya, iyo reactive excitation simba inofanirwa kutorwa kubva kune yemagetsi grid kuti ishatise simba remagetsi remagetsi.Naizvozvo, masynchronous motors anowanzo shandiswa kutyaira yakakwira-simba uye yakaderera-inomhanya michina michina senge bhora zvigayo uye compressors.Nekuti kumhanya kweasynchronous mota ine imwe hukama hwekutsvedza nekutenderera kwayo magineti kumhanya, Kumhanya kwayo kudzora kuita kwakashata (kunze kwe AC commutator mota).Mota yeDC ine mari yakawanda uye yakanakira muchina wekufambisa, chigayo, chigayo chikuru, kudhinda nekudhaya nekugadzira mapepa muchina unoda hupamhi uye hwakatsetseka hwekumhanya kudzora renji.Nekudaro, nekuvandudzwa kweakakwira-simba emagetsi emagetsi uye AC yekumhanyisa regulation system, iyo yekumhanyisa mutemo kuita uye hupfumi hweasynchronous mota inokodzera yakafara kumhanya mutemo inofananidzwa neiyo DC mota.
