Kuyera Permanent Magnet Characteristics

Permanent Magnet Testing: Maonero eTechnician

Kukosha Kwechiyero Chakarurama
Kana iwe ukashanda nemagineti zvikamu, unoziva kuti kuita kwakavimbika kunotanga nekuyera kwakaringana. Iyo data yatinounganidza kubva mukuyedzwa kwemagineti inokanganisa zvakananga sarudzo muinjiniya yemotokari, zvemagetsi zvevatengi, tekinoroji yekurapa, uye kushandiswazve kwesimba rekushandisa.

Mana Critical Performance Parameters
Kana isu tichiongorora magineti echigarire mulabhu, isu tinowanzo kutarisa mana akakosha paramita anotsanangura kugona kwavo:

Br: Memory yeMagnet
Remanence (Br):Fungidzira izvi se "memory" yemagineti yemagnetism. Mushure mekunge tabvisa iyo yekunze magnetizing munda, Br inotiratidza kuti yakawanda sei magineti inochengeta. Izvi zvinotipa hwaro hwesimba remagineti mukushandiswa chaiko.

Hc: Kupokana neDemagnetization
Kumanikidza (Hc):Funga izvi se "willpower" yemagineti - kugona kwayo kuramba demagnetization. Isu tinozvityora muHcb, iyo inotitaurira iyo reverse ndima inodiwa kudzima iyo magineti kubuda, uye Hci, iyo inoratidza kuti yakasimba sei munda watinoda kudzima zvachose kurongeka kwemukati megineti.

BHmax: The Power Indicator
Maximum Energy Product (BHmax):Iyi ndiyo nhamba ine simba-yakazara yatinodhonza kubva kune hysteresis loop. Inomiririra iyo yakanyanya simba yekumisikidza iyo magineti zvinhu zvinogona kuunza, zvichiita kuti ive yedu kuenda-kune metric yekuenzanisa akasiyana magineti marudzi uye mazinga ekuita.

Hci: Kugadzikana Pasi Pekumanikidzwa
Intrinsic Coercivity (Hci):Kune anhasi epamusoro-kuita NdFeB magineti, uku ndiko kugadzira-kana-kupwanya kutaurwa. Kana Hci hunhu hwakasimba, magineti anogona kumira nemamiriro ezvinhu akaomarara - kusanganisira tembiricha yakakwira uye kurwisa magineti - pasina kurasikirwa kukuru kwekuita.

Zvishandiso Zvinokosha zvekuyera
Mukuita, isu tinovimba nemichina yakasarudzika kutora zvivakwa izvi. Iyo hysteresisgraph inoramba iri bhiza redu remurabhoritari, ichigadzira iyo yakazara BH curve kuburikidza neinodzorwa magineti kutenderera. Pafekitari pasi, isu tinowanzo chinja kune inotakurika mhinduro senge Hall-effect gaussmeters kana Helmholtz coils kuti ikurumidze kuongororwa kwemhando.

Kuedza Adhesive-Backed Magnets
Zvinhu zvinonyanya kuita nuances patinoyedzaadhesive-backed neodymium magineti. Iko kureruka kweakavakirwa-mukati anonamatira kunouya nemamwe matambudziko ekuyedza:

Fixture Matambudziko
Kukwidza Matambudziko:Iyo inonamira layer inoreva kuti magineti haambogara zvakakwana muyakajairwa bvunzo zvigadziriso. Kunyangwe mapeji emhepo asingaoneki anogona kukanganisa kuverenga kwedu, zvinoda mhinduro dzekugadzira dzekuisa kwakaringana.

Geometry Kufunga
Mafungiro eFomu Factor:Hunhu hwavo hutete, hunopindika hunoda kugadziridzwa. Maseti akajairwa akagadzirirwa mabhuroko akaomesesa haashande kana sampuro yako yebvunzo inogona kuchinjika kana isina ukobvu hwakafanana.

Testing Environment Zvinodiwa
Magnetic Isolation Zvinodiwa:Kufanana nekuyedza kwese magineti, isu tinofanirwa kupesana nezvekuchengeta zvese zvisiri-magineti padyo. Nepo iyo yekunamira pachayo isina magineti isina kwayakarerekera, chero maturusi esimbi ari padyo kana mamwe magineti anokanganisa mhedzisiro yedu.

Nei Kuedza Kuchikosha?
Mateki ekuongorora chokwadi akakwira. Kunyangwe isu tichikodzera magineti emagetsi mota drivetrains kana zvekurapa zvekuongorora, hapana nzvimbo yekukanganisa. Nemhando dzakanamira-dzinotsigirwa, hatisi kungotarisa simba remagineti - isu tiri kuona kusimba kwekupisa, sezvo iyo inonamira layer inowanzotadza pamberi pemagineti pachayo mumamiriro ekupisa kwepamusoro.

Nheyo Yokuvimbika
Pakupera kwezuva, kunyatsoyedzwa kwemagineti haingori cheki chemhando - ndiyo hwaro hwekufungidzira kuita mune yega application. Iwo musimboti wemisimboti anogara akafanana pamhando dzemagineti, asi nyanzvi dzehunyanzvi dzinoziva nguva yekuchinjisa nzira dzadzo dzemakesi akakosha senge anonamira-akatsigira dhizaini.
