Kuenzaniswa neasynchronous motors, inogara magineti synchronous motors ine akawanda ari pachena mabhenefiti. Permanent magnet synchronous motors ane akawanda maficha akadai seyakakwira simba chinhu, yakanaka kutyaira kugona index, saizi diki, huremu huremu, kukwira kwakadzika tembiricha, nezvimwe. kusvika pakukwanisa kwegridhi yemagetsi iripo, uye chengetedza mari yemagetsi emagetsi.
Kubudirira uye simba factor kuenzanisa
Asynchronous motor mubasa, iyo rotor inotenderera kuti inotora chikamu chesimba kubva kune grid excitation, kuitira kuti kushandiswa kwegridi simba, chikamu ichi chesimba kusvika kune yekupedzisira ikozvino mu rotor inoputika mukupisa kunopedzwa, kurasikirwa kunoverengera. inenge 20-30% yekurasikirwa kwese kwemotokari, izvo zvinotungamirira zvakananga kuderedzwa kwekushanda kwemotokari. 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 yekuremerwa 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, mukushanda kwakajairwa, iyo rotor uye stator magineti magineti kuenderana kushanda, hapana induced ikozvino mu rotor, hapana kurasikirwa kwerotor kuramba, chete iyi inogona kuvandudza kushanda kwemota ne4% kusvika 50%. Panguva imwecheteyo, nekuti hapana induction yazvino excitation mu rotor yekusingaperi magineti synchronous mota, iyo stator mhepo inogona kunge iri yekuremedza mutoro, zvekuti simba remota rinenge 1. Permanent magineti synchronous mota muyero yekuremerwa. > 20%, kushanda kwayo zvakanaka uye simba rekushandisa rine shanduko shoma, uye kushanda zvakanaka kuri> 80%.
Kutanga torque
Asynchronous mota kutanga, mota inodiwa kuve neyakakura yakaringana yekutanga torque, asi vimba kuti yekutanga ikozvino haina kunyanyokurisa, kuitira kuti isaburitse yakawandisa kudonha kwemagetsi mugidhi uye kukanganisa kushanda kwakajairwa kwemamwe mota nemidziyo yemagetsi yakabatana. kugridi. 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 kutanga modhi, nekuda kwechigarire magineti synchronous mota yakajairika kushanda kweiyo rotor mhepo haishande, mukugadzirwa kwechigarire magineti mota, iyo rotor mhepo inogona kuitwa kuzadzisa zvizere zvinodiwa yakakwira yekutanga torque, semuenzaniso, kuitira kuti yekutanga torque kuwedzera neasynchronous mota 1.8 nguva kusvika 2.5 nguva, kana kutopfuura, mhinduro iri nani kune yakajairwa magetsi midziyo, Inogadzirisa zvinobudirira chiitiko che "mabhiza mahombe anodhonza mota diki.t” mumidziyo yemagetsi yakajairika.
Operationkukwira kwekushisa
Sezvo iyo asynchronous mota basa, iyo rotor inomonereka ikozvino kuyerera, uye ikozvino iri zvachose muchimiro chekupisa kwesimba rekushandisa, saka mune rotor mhepo inovhuvhuta inoburitsa huwandu hukuru hwekupisa, kuitira kuti tembiricha yemota inokwira, iyo inokanganisa zvakanyanya. hupenyu hwebasa hwemota.
Kana iri magineti echigarire synchronous mota, nekuda kwekushanda kwakanyanya kwechigarire magineti mota, hapana kurasikirwa kwekupokana mumhepo yerotor, pane kushoma kana kupotsa kushaikwa ikozvino mumhepo inoputika, kuitira kuti tembiricha yemota ikwire. , izvo zviri nani zvinowedzera hupenyu hwebasa hwemotokari.
Kufurira pakushanda kwegridi
Nekuda kweiyo yakaderera simba chinhu cheasynchronous mota, mota inoda kutora huwandu hwakakura hweiyo reactive ikozvino kubva kune yemagetsi gidhi, nekudaro ichikonzeresa yakawanda yeanoshanda ikozvino mugedhi remagetsi, kuendesa uye shanduko midziyo uye magetsi ekugadzira magetsi, nekudaro kugadzira. iyo yemhando yegetsi yemagetsi inoderera, iyo isingangokwidzi mutoro wegidhi remagetsi uye kutumira uye shanduko yemidziyo uye midziyo yekugadzira magetsi, panguva imwecheteyo, iyo inoshanda ikozvino inoshandisa chikamu chemagetsi mugetsi remagetsi, kutumira uye midziyo yekushandura uye midziyo yekugadzira 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 kune yekambani mutemo we "yekutanga-kirasi zvigadzirwa, yekutanga-kirasi manejimendi, yekutanga-kirasi masevhisi, uye ekutanga-kirasi mhando", kurongedza hungwaru hwechigarire magineti mota system inochengetedza mhinduro dzese dzevashandisi. , uye kuyedza kuve mutungamiri uye akajairwa seta muChina isingawanzo pasi inogara magineti mota indasitiri.
