Kuenzaniswa neasynchronous motors, inogara magineti synchronous motors ine akawanda ari pachena mabhenefiti. Permanent magineti synchronous motors ane akawanda maficha akadai seyakakwira simba chinhu, yakanaka kutyaira kugona index, diki saizi, huremu huremu, yakaderera tembiricha kukwira, etc. Panguva imwecheteyo, ivo vanogona kuvandudza zvirinani kunaka kweiyo grid yemagetsi, kupa kutamba kwakazara kune kugona kweiyo iripo gidhi remagetsi, uye chengetedza iyo investimendi yemagetsi grid.
Kubudirira uye simba factor kuenzanisa
Asynchronous mota mubasa, iyo rotor inomonereka kutora chikamu chesimba kubva kune grid excitation, kuitira kuti mashandisirwo emagetsi egidhi, ichi chikamu chesimba kusvika kune yekupedzisira ikozvino mune rotor mhepo mukupisa kunopedzwa, kurasikirwa kunosvika 20-30% yekurasikirwa kwese kwemota, izvo zvinotungamira zvakananga kudzikisira kugona kwemota. Rotor excitation ikozvino yakashandurwa kuita stator winding is inductive current, kuitira kuti ikozvino mu stator winding inononoka kuseri kwegrid voltage, zvichiita kuti kuderedzwa kwesimba remagetsi.
Uye zvakare, asynchronous mota mune inoremerwa chinhu (= P2 / Pn) <50%, kushanda kwayo uye kushanda kwayo simba chinhu inodonha zvakanyanya, saka kazhinji inoda kuti ishande munzvimbo yehupfumi, ndiko kuti, chiyero chekuremerwa che75% -100%.
Permanent magineti synchronous mota mune rotor yakanyudzwa mune isingaperi magineti, iyo isingaperi magineti yekumisikidza rotor magineti, mune yakajairika kushanda, iyo rotor uye stator magineti magineti kuenderana kushanda, hapana induced ikozvino mu rotor, hapana rotor kuramba kurasikirwa, iyi chete inogona kuvandudza kushanda kwemota ne4% kusvika 50%. Panguva imwecheteyo, nokuti hapana induction ikozvino excitation mu rotor yekusingaperi magineti synchronous motor, stator winding inogona kunge iine resistive load, kuitira kuti simba remotokari rive rinenge 1. Permanent magnet synchronous motor mumuyero wekutakura> 20%, kushanda kwayo kushanda uye simba rekushandisa rine shanduko shoma, uye kushanda kwekushanda ndiko> 80%.
Kutanga torque
Asynchronous mota kutanga, mota inodikanwa kuti ive nehombe yakakwana yekutanga torque, asi vimba kuti yekutanga ikozvino haina kunyanyokurisa, kuitira kuti isaburitse yakawandisa kudonha kwemagetsi mugidhi uye kukanganisa kushanda kwakajairika kwemamwe mota nemidziyo yemagetsi yakabatana kune grid. Uye zvakare, kana iyo yekutanga ikozvino yakakura kwazvo, mota pachayo ichave yakatarisana neakanyanya simba remagetsi simba, kana kazhinji inotanga, pane njodzi yekupisa mamhepo. Naizvozvo, asynchronous mota yekutanga dhizaini inowanzotarisana nedambudziko.
Permanent magineti synchronous mota inogona zvakare kushandiswa asynchronous yekutanga modhi, nekuda kweiyo inogara magineti synchronous mota yakajairwa kushanda kweiyo rotor mhepo haishande, mukugadzirwa kwechigarire magineti mota, iyo rotor mhepo inogona kuitwa kuti ikwane zvizere zvinodikanwa zveiyo yepamusoro yekutanga torque, semuenzaniso, kuti yekutanga torque inowedzeredza neasynchronous nguva, kana dhizaini huru kune 25. midziyo yemagetsi, Inogadzirisa zvinobudirira chiitiko che "mabhiza mahombe anodhonza mota dikit” mumidziyo yemagetsi yakajairika.
Operationkukwira kwekushisa
Sezvo iyo asynchronous mota basa, iyo rotor inomonereka ikozvino kuyerera, uye ikozvino iri zvachose muchimiro chekupisa kwesimba rekushandisa, saka mumhepo inotenderera inoburitsa huwandu hukuru hwekupisa, kuitira kuti tembiricha yemota inokwira, iyo inokanganisa zvakanyanya hupenyu hwebasa remota.
Kana iri magineti echigarire synchronous mota, nekuda kwekushanda kwakanyanya kwechigarire magineti mota, hapana kurasikirwa kwekupokana mumhepo inotenderera, pane kushoma kana kunenge kusina reactive ikozvino mu stator winding, kuitira kuti tembiricha yemota ikwire, izvo zviri nani zvinowedzera hupenyu hwesevhisi yemota.
Kufurira pakushanda kwegridi
Nekuda kweiyo yakaderera simba chinhu cheasynchronous mota, mota inoda kutora huwandu hwakakura hweiyo reactive ikozvino kubva kune yemagetsi grid, zvichikonzera huwandu hukuru hwemagetsi emagetsi mugedhi remagetsi, kutapurirana uye shanduko yemidziyo nemagetsi ekugadzira magetsi, zvichiita kuti hunhu hwegedhi remagetsi hudzike, izvo zvisingango wedzera kuremerwa kwegidhi remagetsi uye kutapurirana uye kushandura midziyo nemagetsi ekugadzira magetsi, panguva imwe chete yemagetsi emagetsi, panguva imwe chete magetsi emagetsi. kutapurirana uye kushandura midziyo uye magetsi ekugadzira magetsi, zvichikonzera kuderera kwekushanda uye kukanganisa magetsi emagetsi. Panguva imwecheteyo, reactive current inoshandisa chikamu chemagetsi emagetsi mumagetsi emagetsi, kutumira uye kushandura midziyo uye midziyo yekugadzira magetsi, izvo zvinoita kuti girasi remagetsi rirege kushanda uye rinokanganisa kushandiswa kwesimba remagetsi. Saizvozvo, nekuda kwekushomeka kwemagetsi easynchronous motors, kuzadzisa kudiwa kwesimba rinobuda, zvinodikanwa kutora simba rakawanda kubva kune grid, nekudaro kuwedzera kurasikirwa kwesimba remagetsi uye kuwedzera mutoro pane grid.
Uye kune yekusingaperi magineti synchronous mota, rotor yayo isina induction ikozvino excitation, mota simba chinhu chakakwira zvakare, izvo zvisingangogadzirise kunaka kweiyo grid, kuitira kuti grid haichada kuisa reactive magetsi ekubhadhara michina. Uyezve, nekuda kwekushanda kwepamusoro kweiyo inogara magineti synchronous mota, inochengetedzawo simba regridi
Anhui Mingteng Permanent-Magnetic Machinery&Electrical Equipment Co., Ltd.yakavambwa muna 2007 uye ndeimwe yevagadziri vekutanga muChina kugadzira uye kugadzira zvisingaperi magineti mota. Iyo ine yakazara R&D, kugadzira, kutengesa, uye mushure-yekutengesa timu. Iyo kambani inogara ichiomerera kune yakazvimirira hunyanzvi uye inoomerera kuhurongwa hwekambani hwe "yekutanga-kirasi zvigadzirwa, yekutanga-kirasi manejimendi, yekutanga-kirasi masevhisi, uye ekutanga-kirasi mhando", kurongedza hungwaru hwekusingaperi magineti mota system inochengetedza mhinduro dzese dzevashandisi, uye kuyedza kuve mutungamiri uye akajairwa seta muChina isingawanzo garagi magineti mota indasitiri.
