nkhani

Kusankha mota ya micro DC kungawoneke ngati kosavuta, koma kusankha kolakwika kungayambitse kusagwira bwino ntchito, phokoso lalikulu, kapena kulephera msanga. Monga wopanga, timaona makasitomala ambiri akuvutika ndi magawo oyambira. Nayi chitsogozo cha sitepe ndi sitepe kuti chikuthandizeni kusankha bwino.

1. Fotokozani malire anu a magetsi ndi magetsi

Ma mota ambiri a micro DC amayendetsa pa 3V, 6V, 12V, kapena 24V. Mphamvu yamagetsi yokwera nthawi zambiri imatanthauza mphamvu yamagetsi yotsika pa mphamvu yomweyo, koma mphamvu yamagetsi ya makina anu ndi IC ya driver zidzatsimikizira kuchuluka kwa mphamvu zomwe zingagwiritsidwe ntchito. Nthawi zonse yang'anani mphamvu yamagetsi yopanda katundu ndi stall - zimakhudza moyo wa batri komanso kutayika kwa kutentha.

2. Liwiro ndi mphamvu zigwirizane ndi katundu wanu

Liwiro (RPM) ndi torque (g·cm kapena mNm) ndi zinthu ziwiri zofunika kwambiri. Cholakwika chofala kwambiri ndi kuyang'ana kwambiri liwiro lokha. Mwachitsanzo, fani yaying'ono imafuna liwiro lalikulu koma torque yochepa, pomwe loko yoyendetsedwa ndi giya imafuna torque yayikulu pa liwiro lotsika. Gwiritsani ntchito torque ya injini (yomwe ikupezeka patsamba la data) kuti mupeze malo ogwirira ntchito. Ngati torque yanu yonyamula katundu ipitirira torque yovomerezeka ya injini, injiniyo ikhoza kuyima kapena kutentha kwambiri.

3. Sankhani pakati pa burashi ndi burashi

Ma mota a DC opangidwa ndi brushed ndi otsika mtengo komanso osavuta kuwalamulira pogwiritsa ntchito PWM yosavuta. Ndi abwino kwambiri pa ntchito zogwira ntchito nthawi ndi nthawi kapena zotsika mtengo monga zoseweretsa, mapampu, ndi ma actuator. Ma mota a DC opanda brushless (BLDC) amapereka mphamvu zambiri, moyo wautali, komanso phokoso lochepa lamagetsi, koma amafunika chowongolera zamagetsi. Sankhani BLDC kuti mugwiritse ntchito mosalekeza (monga mafani, zida zamankhwala, maloboti).

4. Ganizirani kukula ndi kuyika

Fakitale yathu imapanga ma mota kuyambira 6mm mpaka 60mm m'mimba mwake. Yesani malo omwe alipo mu chipangizo chanu - musaiwale kutalika kwa shaft ndi mawonekedwe a cholumikizira. Mabowo okhazikika kapena mabulaketi amatha kusinthidwa, koma zida zapadera zimawonjezera ndalama ndi nthawi yotsogolera.

5. Yang'anani zofunikira pa chilengedwe ndi moyo wonse

Kutentha kwa ntchito, chinyezi, fumbi, ndi kugwedezeka zonse zimakhudza moyo wa galimoto. Pa ntchito zakunja kapena zamagalimoto, yang'anani ma IP ratings (monga, IP54). Pazinthu zomwe zimakhala nthawi yayitali (maola opitilira 1000), ganizirani maburashi achitsulo chamtengo wapatali kapena mapangidwe opanda burashi. Pemphani malipoti oyesa moyo kuchokera kwa ife.

Langizo lomaliza: nthawi zonse yesani ndi katundu wanu weniweni. Ma datasheet ndi poyambira, koma magwiridwe antchito enieni amatha kusiyana. Funsani zitsanzo ndikutsatira kutsimikizira kwanu. Mota yosankhidwa bwino imasunga ndalama, nthawi, komanso mavuto a chitsimikizo.
