Kusanthula kwa Hall Probe (Kugawa kwa Field)

Kusanthula kwa Hall probe kumayesa kufalikira kwa mphamvu ya maginito pamwamba pa maginito — kofunikira kwambiri pa mphete zokhala ndi mitengo yambiri.

Mfundo yaikulu:Chipangizo chofufuzira cha Hall chimazungulira ndikusanthula pamwamba pa maginito, ndikulemba mphamvu ya malo pamalo aliwonse a angular.

Cholinga:Tsimikizirani kusinthasintha kwa pakati pa pole, mawonekedwe a mafunde a m'munda (kuyera kwa sinusoidal/square-wave), ndi kukhazikika kwa pole-pitch m'ma ring a pole ambiri.

Muyeso wofunikira:Kupatuka kwa minda pakati pa mitengo yoyandikana sikuyenera kupitirira ±3%; mphete zolembera ma encoder zimafuna ±1%.

Makasitomala a encoder nthawi zambiri amafuna malipoti ofufuza a Hall probe. Ku Fullzen, ichi ndi chinthu chodziwika bwino cha QC cha mphete za encoder.

Njira Yogwiritsira Ntchito Ufa wa Iron (Kuyang'ana Mwachangu)

Njira ya ufa wachitsulo ndiyo njira yowunikira bwino kwambiri — ufa wachitsulo womwe umathiridwa pamwamba pa maginito umafanana ndi mizere ya flux, ndikuwulula mwachindunji kufalikira kwa munda.

Cholinga:Kutsimikizira mwachangu kuti njira yoyendetsera maginito ndi yolondola, kuchuluka kwa mizati ndi kolondola, ndipo palibe zolakwika zoonekeratu za maginito.

Malire:Kulondola kokha; sikupereka manambala. Kulondola kuli kocheperako poyerekeza ndi Hall probe scanning.

Njira ya ufa wachitsulo nthawi zambiri imagwiritsidwa ntchito poyang'ana koyamba komanso kusanja mwachangu pamzere wopanga — si yoyenera QC yotuluka, koma yabwino kwambiri poyang'ana komwe kukubwera komanso kutsimikizira mwachangu pambuyo pa maginito.

FAQ

Q: Kodi maginito a mphete angasinthidwenso mbali ina pambuyo pa maginito oyamba?

A: Ayi. Pa maginito a mphete a NdFeB opindidwa, mawonekedwe a maginito amadziwikiratu panthawi yokanikiza. Akangoyikiridwa, kubwezeretsanso maginito mbali ina sikungagwire ntchito chifukwa ma domain a maginito amakhala atagwirizana kale. Ngati mukufuna kusintha njira ya maginito, muyenera kuyitanitsa maginito atsopano ndi mawonekedwe oyenera musanakanikize. Ku Fullzen Technology, timatsimikizira njira ya maginito mu gawo lowunikira zojambula kuti tipewe vutoli.

Q: Kodi maginito a mphete ya OD ya 30 mm angathandizire mitengo ingati?

A: Magineti ya mphete ya 30 mm OD nthawi zambiri imatha kunyamula mipiringidzo mpaka 16-20, kutengera makulidwe a khoma ndi m'lifupi mwake. Ndi mipiringidzo yocheperako ya mipiringidzo ya 3 mm, kuzungulira kwakunja kumalola mipiringidzo pafupifupi 31, koma zoletsa zenizeni - kulondola kwa chogwirira cha maginito, makulidwe a khoma, ndi kutayikira kwa madzi pakati pa mipiringidzo - zimachepetsa mapangidwe ambiri ku mipiringidzo 16-20. Tikukulimbikitsani kutsimikizira kuchuluka kwa mipiringidzo yanu ndi gulu lathu la mainjiniya musanayitanitse mipiringidzo.

Q: N’chifukwa chiyani maginito a radial ndi okwera mtengo kuposa axial?

Yankho: Kuyika maginito pa radial kumafuna chogwirira ntchito chomwe chimapanga munda wolimba wa radial kuchokera ku ID kupita ku OD, chomwe chimakhala chovuta kupanga ndi kupanga kuposa chogwirira chosavuta cha axial plate. Zogwirira ntchito pa radial nthawi zambiri zimadula nthawi 5-20 kuposa zogwirira pa axial ($600–$6,000+ kutengera kukula kwa mphete ndi kuchuluka kwa pole). Kuphatikiza apo, kuyika maginito pa radial kumakhala ndi chiwongola dzanja chotsika (nthawi zambiri 90–95% vs 98%+ pa axial) chifukwa cha kufunikira kwakukulu kwa mphamvu yamunda komanso kulondola koyenera.

Q: Ndi chitsanzo chiti cha maginito chomwe chili chabwino kwambiri pa ma mota a BLDC?

A: Pa ma mota ambiri a BLDC, maginito a radial okhala ndi pole zambiri ndi omwe amasankhidwa mwachizolowezi. Ma mota a Inrunner BLDC nthawi zambiri amagwiritsa ntchito pole 8-14; ma mota a outrunner amagwiritsa ntchito pole 12-24. Njira ya radial field (ID-to-OD) imagwirizana ndi njira ya air gap flux, zomwe zimapangitsa kuti kugwiritsa ntchito maginito a axial kukhale kokwera ndi 15-20% kuposa axial magnetization. Ku Fullzen Technology, ma oda opitilira 70% a makasitomala athu amatchula maginito a radial okhala ndi pole zambiri.

Q: Kodi kutentha kwakukulu kogwirira ntchito kwa maginito a mphete ya pole zambiri ndi kotani?

A: Maginito a mphete ya pole zambiri amatsatira malire ofanana a kutentha monga maginito a mphete wamba — magiredi a N35–N45 amagwira ntchito mpaka 80°C, pomwe magiredi a SH amagwira 150°C ndipo magiredi a UH amagwira 180°C. Komabe, mphete za pole zambiri zimakhala ndi chiopsezo chachikulu cha demagnetization pa kutentha kwakukulu chifukwa magawo a pole woonda amakhala ndi kukana kochepa kwa demagnetization. Pakugwiritsa ntchito mota pamwamba pa 120°C, tikupangira kugwiritsa ntchito 38SH kapena 40UH grade m'malo mwa N42 wamba.
