T: Za a iya sake haɗa maganadisu ta zobe zuwa wata hanya daban bayan fara maganadisu?

A: A'a. Ga maganadisu na zobe na NdFeB da aka sintered, ana tantance yanayin maganadisu a lokacin matsi. Da zarar an haɗa maganadisu, sake haɗa maganadisu a wata hanya daban ba zai yi aiki ba saboda yankunan maganadisu sun riga sun daidaita. Idan kuna buƙatar canza alkiblar maganadisu, dole ne ku yi odar sabbin maganadisu tare da daidaitaccen alkiblar da aka ƙayyade kafin a danna. A Fullzen Technology, muna tabbatar da alkiblar maganadisu a matakin sake duba zane don guje wa wannan matsala.

T: Dogayen sanda nawa ne maganadisu na zobe mai girman mm 30 zai iya tallafawa?

A: Magnet mai zobe mai girman mm 30 zai iya ɗaukar har zuwa sanduna 16-20, ya danganta da kauri na bango da mafi ƙarancin faɗin sandunan. Tare da mafi ƙarancin baka na sandunan 3 mm, kewayen waje yana ba da damar kusan sanduna 31 mafi girma, amma ƙuntatawa masu amfani - daidaiton kayan aikin maganadisu, kauri na bango, da ɗigon kwararar tsakanin sandunan - suna iyakance yawancin ƙira zuwa sanduna 16-20. Muna ba da shawarar tabbatar da adadin sandunan ku tare da ƙungiyar injiniyanmu kafin yin odar kayan aiki.

T: Me yasa magnetization na radial ya fi tsada fiye da axial?

A: Magnetization na radial yana buƙatar kayan aiki na musamman wanda ke samar da ƙarfin filin radial daga ID zuwa OD, wanda ya fi rikitarwa don tsarawa da ƙera fiye da kayan aiki na farantin axial mai sauƙi. Kayan aikin radial yawanci suna kashe kuɗi sau 5-20 fiye da kayan aikin axial ($600-$6,000+ dangane da girman zobe da adadin sandunan). Bugu da ƙari, magnetization na radial yana da ƙarancin ƙimar yawan amfanin ƙasa (yawanci 90-95% vs 98%+ don axial) saboda buƙatun ƙarfin filin da daidaiton daidaitawa da ake buƙata.

T: Wane tsari ne na maganadisu ya fi dacewa da injinan BLDC?

A: Ga yawancin injinan BLDC, magnetization na radial mai yawa shine zaɓi na yau da kullun. Injinan Inrunner BLDC yawanci suna amfani da sanduna 8-14; injinan da suka wuce gona da iri suna amfani da sanduna 12-24. Alkiblar filin radial (ID-zuwa-OD) ta yi daidai da hanyar kwararar iska, tana samar da amfani mafi girma na 15-20% fiye da magnetization na axial. A Fullzen Technology, sama da kashi 70% na umarnin abokan cinikin motarmu sun ƙayyade magnetization na radial mai yawa.

Tambaya: Menene matsakaicin zafin aiki na maganadisu na zobe masu yawa?

A: Magnet ɗin zobe mai sanduna da yawa suna bin iyakokin zafin jiki iri ɗaya da maganadisu na zobe na yau da kullun - maki N35–N45 suna aiki har zuwa 80°C, yayin da maki SH suna aiki har zuwa 150°C kuma maki UH suna aiki har zuwa 180°C. Duk da haka, zoben mai sanduna da yawa suna fuskantar haɗarin rushewa a yanayin zafi mai yawa saboda sassan siririn sanduna suna da ƙarancin juriya ga rushewa. Don aikace-aikacen injin sama da 120°C, muna ba da shawarar amfani da matakin 38SH ko 40UH maimakon matakin N42 na yau da kullun.
