Motar Micro stepper:tare da hankula mataki kwana na 1.8 °, zai iya cimma har zuwa 51200 subdivision / juyawa ta micro stepper drive, da sakawa daidaito iya isa ± 0.09 °

Motar N20 DC: babu aikin sakawa da aka gina a ciki, yana buƙatar encoder don cimma ikon sarrafa matsayi, ƙara yawan encoder yana ba da 12-48CPR

Hankalin injiniya: A cikin al'amuran da ke buƙatar cikakken kulawar matsayi, matakan motsa jiki zaɓi ne na halitta; Don aikace-aikacen da ke buƙatar sarrafa saurin gudu, injinan DC na iya zama mafi dacewa.

2. Halayen juzu'i: Kula da wasan tsakanin jujjuyawar juzu'i da saurin jujjuyawa

Motar Micro stepper:tare da ingantacciyar juzu'i mai ƙarfi (kamar motar NEMA 8 har zuwa 0.15N · m), ƙarfin ƙarfi mai ƙarfi a ƙananan gudu.

Motar N20 DC:karfin juyi yana raguwa tare da karuwa mai sauri, babban gudun babu kaya amma iyakataccen karfin juyi mai kullewa

Teburin Kwatancen Bayanan Gwaji na Gaskiya:

3. Sarrafa rikitarwa: bambance-bambancen fasaha tsakanin bugun jini vs. PWM

Ikon Motar Stepper:yana buƙatar ƙwararren direban stepper don samar da bugun bugun jini da sigina

Gudanar da motocin DC:Sauƙaƙan da'irar H gada na iya cimma gaba da jujjuya juyi da ƙa'idodin saurin gudu

4. Tattalin Arziki: Tunani daga Farashin Raka'a zuwa Jimillar Kuɗin Tsarin

Farashin naúrar mota: Motar N20 DC yawanci yana da fa'idar fa'ida sosai (yawan siyan kusan dalar Amurka 1-3)

Jimlar farashin tsarin: Tsarin motsi na stepper yana buƙatar ƙarin direbobi, amma tsarin saka motocin DC yana buƙatar masu ƙididdigewa da ƙarin hadaddun masu sarrafawa

Hangen sayayya: Ƙananan ayyukan R&D na iya mai da hankali kan farashin raka'a, yayin da manyan ayyukan samarwa dole ne su ƙididdige jimlar farashin tsarin.

A cikin wasu aikace-aikace masu girma, ana iya la'akari da haɗin fasaha guda biyu:

Babban motsi yana amfani da injin stepper don tabbatar da daidaito

Ayyukan taimako suna amfani da injina na DC don sarrafa farashi

Rufe madauki matakin yana ba da mafita ga sasantawa a cikin yanayi inda ake buƙatar aminci

Halin kirkire-kirkire: A cikin ƙirar injin kofi mai tsayi, ana amfani da motar stepper don tabbatar da daidaitaccen wurin tsayawa don ɗaga kai, yayin da ake amfani da injin DC don sarrafa farashi don famfo na ruwa da injin niƙa.

V, Yanayin Gaba: Yadda Ci gaban Fasaha ke Shafar Zaɓuɓɓuka

Juyin Halitta na Fasahar Mota:

Ƙirƙirar tsarin ƙira na injin stepper mai hankali tare da haɗaɗɗen direba

Sabuwar ƙirar da'irar maganadisu tare da mafi girman ƙarfin juyi

Farashin yana raguwa kowace shekara, yana shiga cikin aikace-aikacen tsaka-tsaki

Inganta fasahar motar DC:

Motocin DC masu hankali tare da haɗe-haɗen incoders sun fara fitowa

Aikace-aikacen sababbin kayan yana ci gaba da rage farashi

VI, Jadawalin tsari na zaɓi na zahiri

Ta bin tsarin yanke shawara mai zuwa, za a iya yin zaɓin bisa tsari:

Kammalawa: Neman Ma'auni tsakanin Abubuwan Fasaha da Gaskiyar Kasuwanci

Zaɓa tsakanin injin micro stepper ko injin N20 DC ba shine yanke shawara mai sauƙi ba. Ya ƙunshi fasaha na daidaita aikin injiniyoyi don aiwatarwa tare da sarrafa farashi.

Babban ƙa'idodin yanke shawara:

Lokacin da daidaito da aminci sune abubuwan farko, zaɓi motar stepper

Lokacin da farashi da sauƙi suka mamaye, zaɓi motar DC

Lokacin a tsakiyar yankin, a hankali ƙididdige jimlar farashin tsarin da ƙimar kulawa na dogon lokaci

A cikin yanayin fasahar zamani mai saurin jujjuyawar yau, injiniyoyi masu hikima ba sa tsayawa kan hanya guda ta fasaha, amma suna yin zaɓi mafi ma'ana bisa ƙayyadaddun ƙuntatawa da manufofin kasuwanci na aikin. Ka tuna, babu motar "mafi kyau" kawai, kawai mafita "mafi dacewa".
