Kushandiswa kweNdFeB Permanent Magnets In New Energy Vehicles

At ikozvino, NdFeB yakashandiswa zvakanyanya munzvimbo dzakasiyana siyana, senge marobhoti, maindasitiri motors, midziyo yemumba, earphone, etc. Nhasi tichadaro suma mashandisirwo eNdFeB magineti echigarire mumotokari nyowani dzesimba. Mota dzemagetsi nyowani dzinonyanya kusanganisira mota dzakasanganiswa uye mota dzemagetsi dzakachena. Yepamusoro-inoshanda NdFeB yekusingaperi magineti zvinhu zvinonyanya kushandiswa mukutyaira mota dzemagetsi matsva. Dhiraivha mota dzakakodzera mota nyowani dzesimba kunyanya zvinosanganisira zvechigarire magineti synchronous motors, AC asynchronous motors uye kushandura magineti pakati pavo, iyo inogara magineti synchronous mota ine iva iyo mota huru nekuda kwehupamhi hwekumhanya siyana, yakakwirira simba density, saizi diki, uye kugona kwakanyanya. NdFeB magineti echigarire ane hunhu hwepamusoro magineti simba chigadzirwa, yakakwira intrinsic yekumanikidza simba uye yakakwirira remanence, iyo inogona zvinobudirira kuvandudza simba density uye torque density yemamota, uye anoshandiswa zvakanyanya mune anogara magineti mota rotor.

EPS (Electric Power Steering System) ndicho chikamu chinoshandisa chisingaperi magineti (0.25kg/mota) mukuwedzera kune mota yekutyaira. Simba-kubatsirwa micromotor muEPS inogara magineti mota, ine zvakakwirira zvinodiwa kushanda, uremu uye vhoriyamu. Naizvozvo, iyo yekusingaperi magineti zvinhu mukati EPS inonyanya kuita sintered kana kupisa-kudzvanywa NdFeB magineti.

In kuwedzera kune mota yekutyaira yemota nyowani dzesimba, iwo mota pane yasara mota yacho ese mamicro-motor. Micro-motor dzine zvakaderera zvinodiwa pamagnetism. Parizvino, ferrite ndiyo huru. Nekudaro, kugona kwemotor kushandisa NdFeB inowedzerwa ne8-50%. Iko kushandiswa kwesimba kunoderedzwa ne10% uye iyo uremu hunoderedzwa neanopfuura 50%, iyo yave nzira yekuvandudza ye micro motors mune ramangwana.

For semuenzaniso, akasiyana masensa pamotokari inzvimbo iyo NdFeB isingaperi magineti inoshandiswa kumotokari itsva dzine simba. Masensa anoshandisa magineti echigarire kunyanya zvinosanganisira: kureba sensors, bhureki sensors, chigaro bhandi sensors, etc. Ivo kunyanya shandisa Hall sensors. MuHoro sensors, magineti echigarire anoshandiswa kugadzira magineti ekuita kuti zvinhu zveHoro zviburitse mafashama, nekudaro kugadzira electromotive simba, ine miniaturization uye kubatanidzwa kwe Horo sensor kuvandudza, kusarudzwa kwemagineti echigarire kunowanzo shandisa NdFeB magineti echigarire ane yakanaka magineti zvivakwa uye saizi diki.

Car vatauri zvakare chimwe chiitiko uko NdFeB magineti echigarire anoisirwa motokari itsva dzine simba. Kuita kwemagineti echigarire kune chekuita kwakananga paruzha rwevatauri. Iyo yakakwirira iyo magnetic flux density ye magineti echigarire, anowedzera kunzwisiswa kwevatauri uye zviri nani chenguva pfupi. Kazhinji kutaura, ndiye mutauri Zviri nyore kugadzira a inzwi, uye inzwi harina madhaka. Magineti echigarire evatauri pa musika unonyanya kusanganisira AlNiCo, ferrite uye NdFeB. Iyo magnetic properties ye NdFeB yakakwirira kwazvo kune iyo yeAlNi uye ferrite. Kunyanya kune yepamusoro-soro vatauri, vazhinji vavo vanoshandisa NdFeB.

Yedu kambani inopa akasiyana NdFeB, akasungwa NdFeB, jekiseni rakaumbwa remagineti zvindori, ferrite magineti mataira, NdFeB yakasimba magineti mataira, etc. Isu tinopa customized masevhisi evatengi, ndapota inzwa wakasununguka kutibata nesu kana uchida.
