Mota Dzisina Mabhurashi vs Dzakabhurwa: Ndedzipi Dzakakodzera Purojekiti Yako?

Nhanganyaya

Mhando mbiri dzakajairika dzemota dzeDC imota dzakarukwa nemamota asina mabhurashi (BLDC motors). Sezvinoreva zita racho, mota dzakarukwa dzinoshandisa mabhurashi kuchinja divi, zvichiita kuti mota itenderere. Kusiyana neizvi, mota dzisina mabhurashi dzinotsiva basa rekuchinja mashandiro emagetsi nekutonga kwemagetsi. Mhando dzese dziri mbiri dzinoshanda nepfungwa imwe chete, kureva kukwezvana kwemagineti uye kudzoreredza simba remagetsi pakati pecoil nemagneti inogara iripo. Imwe neimwe ine zvayakanakira nezvayakaipira, izvo zvinogona kukanganisa sarudzo yako zvichienderana nezvinodiwa zvekushandisa kwako. Kunzwisisa mutsauko uripo pakati pemota dzeDC dzakarukwa nemamota eDC asina mabhurashi kwakakosha pakuongorora mashandiro adzo. Sarudzo yekusarudza imwe mhando pane imwe yakavakirwa pane zvakasiyana-siyana zvinodiwa, zvinosanganisira kushanda zvakanaka, hupenyu hwenguva uye mutengo.

Zvinhu zvakakosha pakusiyanisa pakati pemotokari yeDC yakakweshwa neisina brush:

#1. Kushanda Nesimba Zviri Nani

Mota dzisina mabhurashi dzinoshanda zvakanyanya kupfuura mota dzakakweshwa. Dzinoshandura simba remagetsi kuita simba remakanika nemazvo, nokudaro dzichideredza kushaikwa kwesimba. Kusiyana nemamota eDC akakweshwa, mota dzisina mabhurashi hadzina kusangana nekukweshwa kana kurasikirwa nesimba kunokonzerwa nemabhurashi nemakomputa. Izvi zvinovandudza mashandiro, zvinowedzera nguva yekushanda, uye zvinoderedza kushandiswa kwesimba.

Kusiyana neizvi, mota dzakakweshwa dzinoonekwa sedzisina kushanda zvakanaka kupfuura mota dzeDC dzisina mabhurashi nekuda kwekurasikirwa kwesimba kunokonzerwa nekukweshana uye kutamiswa kwesimba kuburikidza nesystem ye commutator.

#2. Kugadzirisa uye Kugara kwenguva refu

Mota dzisina mabhurashidzine zvikamu zvishoma zvinofamba uye hadzina kubatana kwemakanika, zvichikonzera kugara kwenguva refu uye kudzikira kwezvinodiwa pakugadzirisa. Kusavapo kwemabhurashi kunobvisa matambudziko ane chekuita nekusakara kwemabhurashi nezvimwe zvinetso zvekugadzirisa. Saka, mota dzisina mabhurashi dzinowanzova sarudzo inodhura zvishoma kune vashandisi.

Pamusoro pezvo, mamota ane mabhurashi anoda kugadziriswa zvakanyanya nekuda kwekusakara kwemabhurashi ne commutator, izvo zvinogona kukonzera kusashanda zvakanaka uye matambudziko emota. Kuti mabhurashi arambe achishanda zvakanaka, anofanira kutsiviwa nguva nenguva.

#3. Ruzha uye Kudedera

Mumamota asina mabhurashi, simba rekutenderera rinogona kudzorwa, izvo zvinobatsira kuderedza torque pulsations inogona kukonzera kudedera uye ruzha rwemakanika. Nokudaro, mamota asina mabhurashi anowanzo buritsa ruzha rushoma uye kudedera kupfuura mamota ane mabhurashi. Nekuti haana mabhurashi kana macommutator. Kuderedzwa kwekudedera uye ruzha kunovandudza kunyaradzwa kwemushandisi uye kunoderedza kupera nekubvaruka kana ashandiswa kwenguva refu.

Mumota yeDC yakakweshwa, mabhurashi necommutator zvinoshanda pamwe chete senzira yekuchinja. Kana mota ichishanda, maswichi aya anogara achivhurika uye achivhara. Maitiro aya anobvumira mafungu emvura akakwira kuyerera nepakati pemawindings e rotor inductive, zvichiburitsa ruzha rudiki rwemagetsi nekuda kwekuyerera kukuru kwemagetsi.

#4. Mutengo uye Kuoma Kwazvo

Mota dzisina mabhurashi dzinowanzo kudhura zvakanyanya uye dzakaoma nekuda kwesystem yekudzora magetsi yekuchinja. Mutengo wemota dzeDC dzisina mabhurashi wakakwira uchienzaniswa nemota dzeDC dzakakweshwazvinonyanya kukonzerwa nemagetsi epamusoro anoshandiswa mukugadzirwa kwawo.

#5. Dhizaini uye Mashandiro

Mamota eDC asina brushless haazvifambi ega. Anoda dhiraivha inoshandisa ma transistors kudzora magetsi ari kuyerera nepakati pema coil emota. Mamota aya anoshandisa ma electronic controls uye Hall effect sensors kuti agadzirise magetsi ari muma windings, pane kuvimba nekubatanidza magetsi.

Mamota eDC akabhurwa anozvigadzirisa ega, zvichireva kuti haadi circuit yemutyairi kuti ashande. Pane kudaro, anoshandisa mabhurashi emakanika nemacommutator kudzora magetsi ari mumawindings, nokudaro achigadzira simba remagineti. Simba iri remagineti rinogadzira torque, zvichiita kuti mota itenderere.

#6. Mashandisirwo

Sezvo mutengo wemota dzekudederauye magetsi anoshandiswa navo ari kuramba achiderera, kudiwa kwemamota asina mabhurashi nemamota ane mabhurashi kuri kuwedzera. Mamota asina mabhurashi anonyanya kufarirwa pama smartwatches, zvishandiso zvekurapa, zvishandiso zvekunaka, marobhoti, nezvimwewo.

Asi kuchine nzvimbo uko mota dzakakweshwa dzine musoro. Kune kushandiswa kukuru kwemota dzakakweshwa mumafoni, e-cigarettes, video game controllers, eye massager, nezvimwewo.
