Okokuqala, izinga lomthwalo wemoto liphansi.Ngenxa yokukhethwa okungafanele kwenjini, insalela ngokweqile noma izinguquko ohlelweni lokukhiqiza, umthwalo wangempela wokusebenza wenjini ungaphansi kakhulu kunomthwalo olinganiselwe, futhi injini ehlanganisa cishe u-30% kuya ku-40% womthamo ofakiwe ugijima. ngaphansi komthwalo olinganiselwe wama-30% kuya ku-50%.Ukusebenza kahle kuphansi kakhulu.

Okwesibili, i-voltage yokunikezwa kwamandla ayi-asymmetric noma i-voltage iphansi kakhulu.Ngenxa yokungalingani komthwalo wesigaba esisodwa sohlelo lokuphakela amandla kagesi olunezintambo ezine-voltage enezigaba ezintathu, i-voltage yezigaba ezintathu zenjini ayi-asymmetrical, futhi injini ikhiqiza i-torque engalungile yokulandelana.Ukulahlekelwa ekusebenzeni kwamamotho amakhulu.Ngaphezu kwalokho, i-voltage yegridi iphansi isikhathi eside, okwenza i-motor current ekusebenzeni okujwayelekile ibe mkhulu kakhulu, ngakho-ke ukulahlekelwa kuyanda.Uma i-voltage yezigaba ezintathu i-asymmetry enkulu, i-voltage ephansi, ukulahlekelwa okukhulu.

Okwesithathu wukuthi amamotor amadala namadala (aphelelwe yisikhathi) asasetshenziswa.Lawa ma-motor asebenzisa ukufakwa kwe-class E, makhulu, awakwazi ukuqala kahle, futhi awasebenzi kahle.Nakuba isineminyaka ilungiswa, isasetshenziswa ezindaweni eziningi.

Okwesine, ukuphathwa kabi kwesondlo.Amanye amayunithi awagcini ama-motor nemishini njengoba kudingeka, futhi awavumele ukuthi asebenze isikhathi eside, okwenza ukulahlekelwa kuqhubeke kwanda.

Ngakho-ke, ngenxa yalokhu kusebenza kokusetshenziswa kwamandla, kufanelekile ukutadisha ukuthi yiluphi uhlelo lokonga amandla ongalukhetha.

Cishe kunezinhlobo eziyisikhombisa zezixazululo zokonga amandla ezinjini:

1. Khetha injini yokonga amandla

Uma kuqhathaniswa namamotho ajwayelekile, i-motor esebenza kahle kakhulu ilungiselela ukwakheka okuphelele, ikhetha amawindi ethusi ekhwalithi ephezulu namashidi ensimbi ye-silicon, inciphisa ukulahlekelwa okuhlukahlukene, inciphisa ukulahleka ngo-20% ~ 30%, futhi ithuthukisa ukusebenza kahle ngo-2% ~ 7%;isikhathi sokukhokha Ngokuvamile iminyaka engu-1-2, izinyanga ezithile.Uma kuqhathaniswa, injini esebenza kahle kakhulu isebenza kahle ngo-0.413% kune-J02 series motor.Ngakho-ke, kubalulekile ukushintsha amamotho kagesi amadala ngamamotho kagesi asebenza kahle kakhulu.

2. Ukukhetha okulungile kwamandla emoto ukuze kuzuzwe ukonga amandla

Umbuso wenze le mithethonqubo elandelayo yezindawo ezintathu zokusebenza ze-asynchronous motors ezigabeni ezintathu: indawo yokusebenza komnotho iphakathi kuka-70% no-100% wezinga lomthwalo;indawo yokusebenza evamile iphakathi kuka-40% no-70% wezinga lomthwalo;izinga lomthwalo lingama-40% Okulandelayo izindawo zokusebenza okungezona ezomnotho.Ukukhetha okungalungile kwamandla emoto ngokungangabazeki kuzoholela ekumoshweni kwamandla kagesi.Ngakho-ke, ukusebenzisa injini efanelekile ukuthuthukisa isici samandla kanye nezinga lokulayisha kunganciphisa ukulahleka kwamandla futhi konge amandla.

3. Sebenzisa i-magnetic slot wedge esikhundleni seweji yesikhala sokuqala

4. Yamukela i-Y/△ idivayisi yokuguqula okuzenzakalelayo

Ukuze kuxazululwe ukumosheka kwamandla kagesi lapho okokusebenza kulayishwe kancane, ngesisekelo sokungashintshi injini, idivayisi yokuguqula okuzenzakalelayo engu-Y/△ ingasetshenziswa ukufeza inhloso yokonga ugesi.Ngoba kugridi yamandla we-AC yezigaba ezintathu, i-voltage etholwe ukuxhuma okuhlukile komthwalo ihlukile, ngakho-ke amandla athathwe kugridi yamandla nawo ahlukile.

5. Isinxephezelo samandla asebenzayo we-Motor factor

Ukuthuthukisa isici samandla kanye nokunciphisa ukulahleka kwamandla yizinhloso eziyinhloko zesinxephezelo samandla asebenzayo.Isici samandla silingana nesilinganiso samandla asebenzayo namandla abonakalayo.Ngokuvamile, isici samandla aphansi sizobangela amandla amaningi ngokweqile.Ngomthwalo onikeziwe, lapho i-voltage yokuhlinzeka ingashintshi, i-factor yamandla ephansi, i-current enkulu.Ngakho-ke, isici samandla siphezulu ngangokunokwenzeka ukuze wonge amandla kagesi.

6. Ukulawulwa kwesivinini sokuguqulwa kwemvamisa

7. Ukulawulwa kwejubane lamanzi enjini ejikajikayo
