Permanent Magnet Jenareta: An Overview

Nhanganyaya

Permanent magnet generator (PMGs) zvishandiso zvitsva zvinoshandura simba remagetsi kuita simba remagetsi richishandisa magineti echigarire kugadzira magnetic field. Aya majenareta anozivikanwa nekushanda kwawo kwepamusoro, kuvimbika, uye kuderedzwa kwezvinodiwa zvekugadzirisa zvichienzaniswa nemajenareta echinyakare. Ichi chinyorwa chichakurukura zvikamu zvavo, misimboti yekushanda, mhando, uye mashandisirwo.

Zvikamu zvePermanent Magnet Generator

Permanent Magnet Generators (PMGs) akakosha mukushandisa kwakasiyana. Kuti unzwisise mabasa avo, zvakakosha kuongorora zvakakosha zveaya majenareta.

 Rotor:

Rotor ndiyo chikamu chinotenderera chejenareta. Yakaiswa nemagetsi echigarire. Aya magineti anopa inopindirana uye yakasimba magineti munda sezvo rotor inotenderera.

 Stator:

Iyo stator ndiyo yakamira iyo inogara rotor. Iine windings (coils of wire) uko iyo induced voltage inogadzirwa.

 Permanent Magnets:

Magineti echigarire senge neodymium, samarium-cobalt, kana ferrite, anogadzira yakagadzikana magineti pasina kudiwa kwekunze kwesimba sosi. Vanowedzera kushanda kwejenareta.

 Bearings:

Bearings anotsigira rotor, saka rotor inogona kutenderera zvakanaka mukati me stator. Mabhengi emhando yepamusoro anoderedza kukweshana uye kupera uye anoita kuti jenareta rirarame kwenguva refu.

 Kutonhodza System:

PMGs inogona kusanganisira inotonhorera sisitimu yekubvisa kupisa kunogadzirwa panguva yekushanda. Iyo inotonhorera sisitimu inovimbisa kuita kwakaringana uye inodzivirira kupisa.

Kushanda Misimboti yePermanent Magnet Generator

PMGs inoita basa rakakosha mukushandura simba remagetsi kuita simba remagetsi. Heano mashandiro anoita majenareta aya.

1.Pakutanga, simba remagetsi rinoshandiswa kuneshaft, zvichiita kuti itenderere. Sezvo rotor inotenderera, inogadzira shanduko yemagineti. Iyi dynamic magnetic field inobva yapindirana nestator, iyo ine mhangura inomonereka. Kudyidzana pakati pemagineti inotenderera uye mhepo yakamira inoita kuti magetsi avepo mu stator.

2.Zvino, thema bearingschengetedza kuti rotor inotenderera zvakanaka nekudzikisa kukweshera uye kutsigira shaft. Iyo yose nzira inochengeterwa mukati meiyo yakasimbafuremu, kuchengetedza zvikamu zvemukati uye kuchengetedza kuvimbika kwemaitiro.

3.Pakupedzisira,control systemsgadzirisa kubuda kwejenareta, saka simba remagetsi rinogadzirwa rakagadzikana uye rinoenderana. Aya masisitimu anokwirisa mashandiro uye anonatsiridza kugona kwejenareta.

4.Nemitemo iyi yekushanda, Permanent Magnet Generators inonyatsoshandura magetsi emagetsi mumagetsi emagetsi akavimbika, achitsigira zvakasiyana-siyana zvekushandisa.

Mhando dzePermanent Magnet Generators

Aya majenareta anoshanda anouya mumhando dzakasiyana. Chimwe nechimwe chazvo chinokodzera kushandiswa kwakasiyana uye zvinodiwa zvekushanda.

Brushless PMGs inofarirwa zvakanyanya nekuda kwekuderera kwavo kwekugadzirisa zvinodiwa uye hupenyu hurefu. Aya majenareta anobvisa kudiwa kwemabhurashi uye kutsvedza mhete, kuderedza kusakara uye kubvaruka uye kuwedzera kugona kwese.

Axial Flux PMGs inouya ne compact uye lightweight dhizaini. Aya majenareta akanakira kunyorera senge mumaindasitiri emotokari uye aerospace.

Radial Flux PMGs ndiyo yakajairika dhizaini inoshandiswa mumhepo turbines uye maindasitiri maapplication. Aya majenareta anomira pachena pakuvaka kwawo kwakasimba uye kubuda kwemagetsi akawanda, zvichiita kuti ave akakodzera basa rinorema-basa.

High-Speed ​​PMGs akagadzirwa kuti ashande zvakanyanya kutenderera kumhanya, achipa yakakwira simba density. Aya anowanzo shandiswa mumashandisirwo anoda komputa jenareta ine yakakwira simba-kusvika-huremu reshiyo, senge mumamicro-turbines uye madiki-chikero masisitimu emagetsi.

Low-Speed ​​PMGs akanyatsokodzera zvikumbiro senge hydroelectric simba rekugadzira, uko kumhanya kwekutenderera kwakadzikira. Aya majenareta akavakwa kuti ape simba rinoenderana rinobuda kunyangwe nekumhanya kwakaderera, kuve nechokwadi chekuvimbika uye kugona mune avo chaiwo mashandisiro kesi.

Zvishandiso zvePermanent Magnet Jenareta

 1.Wind Turbines:

PMGs anowana kushandiswa kwakakura mumaturbine emhepo nekuda kwekushanda kwawo kwakanyanya uye kuvimbika. Vanoshandura simba remagetsi remashizha anotenderera kuita simba remagetsi, kushandisa simba remhepo kuti rivezve simba rekugadzira.

 2.Hydropower:

Mune madiki-scale hydropower masisitimu, PMGs inoshandura mechanical simba remvura inoyerera kuva simba remagetsi. Kushanda kwavo uye kugadzirisa kwakaderera kunoita kuti vakwanise kunzvimbo dziri kure kana kure-grid.

 3.Electric Vehicles:

PMGs anoshandiswa mumotokari dzemagetsi kugadzira magetsi kubva kune regenerative braking systems, kuvandudza simba rose uye kuwedzera hupenyu hwebhatiri.

 4.Portable jenareta:

Compact uye inobudirira PMGs anobatsira mune anotakurika jenareta, kupa yakavimbika simba sosi yekunze zviitiko, kuvaka nzvimbo, uye emergency backup simba.

 5.Marine Applications:

PMGs anoshandiswa munzvimbo dzemugungwa kugadzira magetsi kubva kumafungu kana simba remvura. Kugara kwavo uye kuramba kumamiriro ezvinhu akaoma kunoita kuti vakwanise kushandiswa mugungwa.

Kubudirira uye Kuchengetedza

Permanent maginereta anoshanda zvakanyanya nekuda kwekuenderana uye kwakasimba remagineti inopihwa neanogara magineti. Vanoda kugadziridzwa kushoma kana zvichienzaniswa nemajenareta echinyakare, sezvo vachishaya mabhurashi uye zvindori zvinotsvedza zvinopera nekufamba kwenguva. Kugara uchiongorora mabheri uye kutonhora masisitimu, pamwe nekuchenesa nguva nenguva, inova nechokwadi chekushanda kwakakwana uye hupenyu hurefu.

Mhedziso

Permanent maginereta majenareta akakosha kufambira mberi mujenareta tekinoroji nekuda kwekuita kwavo kwakanyanya, kuvimbika, uye kuderera kwekugadzirisa. Kunzwisisa zvikamu zvavo, misimboti, mhando, uye mashandisirwo kwakakosha pakusimudzira mabhenefiti avo munzvimbo dzakasiyana siyana.

Kubva kumagetsi emagetsi emagetsi semhepo uye simba remvura kuenda kumotokari dzemagetsi uye majenareta anotakurika, maPMG anoita basa rakakosha mukugadzira simba kwemazuva ano. Ivo vari kuzotungamira kune remangwana rakagadzikana uye rinoshanda.
