Nekufarirwa kwesimba remagetsi rinoshanduka-shanduka, dambudziko rekutanga remota rave nyore kugadzirisa, asi kune magetsi akajairwa, kutanga kwerotor yekeji yetsindimota dzisina simba rakawanda dzagara dziri dambudziko. Kubva mukuongorora mashandiro ekutanga uye ekushanda kwemamota asina simba, zvinogona kuonekwa kuti kuti kuwedzera torque yekutanga uye kuderedza simba panguva yekutanga, kuramba kwerotor kunofanirwa kunge kwakakura; nepo mota iri kushanda, kuti kuderedza kurasikirwa kwemhangura yerotor uye kuvandudza kushanda kwemota, kuramba kwerotor kunofanirwa kunge kudiki; izvi zviri pachena kuti zvinopesana.
Kune mamota e rotor e wound, sezvo resistor ichigona kubatanidzwa mumutsara panguva yekutanga uye yozobviswa panguva yekushanda, chinodiwa ichi chinozadzikiswa zvakanaka. Zvisinei, mota ye rotor ye wound asynchronous ine chimiro chakaoma, inodhura zvakanyanya, uye kugadzirisa kusina kunaka, izvo zvinoderedza kushandiswa kwayo kusvika pamwero wakati; izvi zvinokurudzira vanhu kuti vatange kubva pachimiro che rotor che keji ye squirrel.mota isina kuenderanauye edza kushandisa "mhedzisiro yeganda" kuti uwane chinangwa chekudzivirira kukuru kwekutanga uye kudzivirira kudiki panguva yekushanda. Mamota e rotor e deep slot uye double squirrel cage ane mashandiro aya ekutanga. Nhasi, ngatitaurei nezvemamota e deep slot rotor.
Mota yakadzika isina simba
Kuti ganda riwedzere kushanda zvakanaka, chimiro chemugero we deep slot asynchronous motor rotor chakadzika uye chakamanikana, uye chiyero chekudzika kwemugero kusvika paupamhi hwemugero chiri pakati pe10-12. Kana magetsi achipfuura nemumigero yerotor, kuyerera kwemugero kwakabatana nepasi pemigero kwakakura kupfuura kuyerera kwemugero kwakabatana nekuvhurwa kwemugero. Saka, kana migero ichionekwa semakondirakiti madiki akakamurwa pamwe chete nekukwirira kwemugero kwakabatana zvakafanana, makondirakiti madiki ari pedyo nepasi pemugero ane kuyerera kukuru, uye kana mugero uri pedyo, kuyerera kwemugero kudiki.
Pakutanga, sezvo frequency yerotor current yakakwira uye leakage reaction yakakura, kupararira kwe current mu diki rega rega conductor kunoenderana ne leakage reaction. Leakage reaction yakakura, leakage current idiki. Nenzira iyi, pasi pesimba rimwechete rinokonzerwa ne main magnetic flux yemhepo gap, current density iri pedyo nepasi pe slot iri mumabhawa ichave diki kwazvo, uye kana slot opening iri pedyo, current density yakakura.
Nekuda kweganda, mushure mekunge simba rakawanda remagetsi radzvanywa pamusoro pebhawa remuchina wemagetsi, basa rebhawa remuchina wemagetsi riri pasi penzvimbo yacho diki kwazvo, izvo zvakaenzana nekuderedza kukwirira uye chikamu chebhawa remuchina wemagetsi, saka kuramba kwerotor kunowedzera, uye kunosangana nezvinodiwa zvekudzivirira kukuru pakutanga. Kana mota yatanga uye mota yave kushanda zvakanaka, nekuda kwehuwandu hushoma hwesimba remuchina wemagetsi wemagetsi wemagetsi, kuyerera kwemhepo kwemuchina wemagetsi ...
Sezvo kuramba kwemuchina wega wega mudiki kwakaenzana, simba remagetsi riri muchina uyu richagoverwa zvakaenzana, saka ganda rinopera, uye kuramba kwemuchina uyu kunova kudiki zvakare, pedyo nekuramba kweDC. Zvinogona kuonekwa kuti kushanda kwakajairika kwesimba remuchina uyu kuchadzikira otomatiki, nokudaro zvichisangana nemhedzisiro yekuderedza kurasikirwa kwemhangura uye kuvandudza kushanda zvakanaka.
Chii chinoita kuti ganda rive nemhedzisiro yacho?
Mhedzisiro yeganda inonziwo mhedzisiro yeganda. Kana alternating current inopfuura nemu conductor, current inozonyanya kutarisisa pamusoro pe conductor. Chiitiko ichi chinonzi mhedzisiro yeganda. Kana current kana voltage zvikaitwa mu conductor nema electron ane frequency yakakwira, zvinoungana pamusoro pe conductor yese pachinzvimbo chekugoverwa zvakaenzana munzvimbo ye cross-section ye conductor yese.
Kushanda kweganda hakungokanganisi chete kuramba kwerotor, asiwo kukanganiswa kwekubuda kwerotor. Kubva munzira yekubuda kweslot leakage flux, zvinoonekwa kuti magetsi anopfuura nemumuchina mudiki anongoburitsa kubuda kwemvura kubva kumuchina mudiki kuenda kumuchina, asi kwete kubva kumuchina mudiki kuenda pasi peslot, nekuti wekupedzisira hauna hukama nemagetsi. Nenzira iyi, kune magetsi akafanana, kuswedera pedyo nepasi peslot, kubuda kwemvura kunowedzera, uye kuswedera pedyo neslot, kubuda kwemvura kushoma kunogadzirwa. Zvinoonekwa kuti kana ganda richidzvanya magetsi ari mumuchina kuenda kumuchina, kubuda kwemvura kunokonzerwa nemuchina mumwechete kunoderedzwa, saka kubuda kwemvura kunoderedza. Nokudaro, ganda rinowedzera kuramba kwerotor uye rinoderedza kubuda kwemvura kurotor.
Simba rekushanda kweganda rinoenderana nekufamba kwenguva kwe rotor current uye saizi ye slot. Kana frequency yakakwira uye yakadzika slot, mhedzisiro yeganda ichave yakakosha. Kune rotor imwechete, kana frequency yakasiyana, mhedzisiro yeganda ichave yakasiyana, uye ma parameter e rotor achave akasiyanawo. Nekuda kweizvi, kuramba kwe rotor uye kudonha kwemvura panguva yekushanda kwakajairika uye kutanga kunofanirwa kusiyanisa zvakanyanya uye hakugone kuvhiringidzwa. Kune frequency imwe chete, mhedzisiro yeganda ye deep groove rotors yakasimba kwazvo, asi mhedzisiro yeganda inewo mwero wakati wepesvedzero pa rotors dze squirrel cage. Naizvozvo, kunyangwe kune rotor ye squirrel-cage ine chimiro chakajairika, ma parameter e rotor pakutanga uye kushanda anofanirwa kuverengerwa zvakasiyana.
Kubuda kwemvura murotor yakadzikamota isina kuenderana, nekuda kwechimiro chemugero wakadzika werotor, inodzikiswa nemhedzisiro yeganda, asi mushure mekuderedzwa, kuyerera kwemugero werotor kuchiri kukuru kupfuura kwerotor yemugero wakajairika wesquirrel cage. Nokudaro, simba remagetsi uye torque yepamusoro yemota dzemugero wakadzika zvakaderera zvishoma pane zvemota dzemugero wakajairika wesquirrel cage.
