Direct current (DC) le alternating current (AC) motors ke mefuta e 'meli ea motlakase e sebelisoang hangata. Pele re tšohla phapang pakeng tsa mefuta ena e ’meli, a re qaleng ka ho utloisisa hore na ke eng.
Enjene ea DC ke mochini o potolohang oa motlakase o ka fetolang matla a motlakase hore e be matla a mochini (ho potoloha). E ka boela ea sebelisoa e le jenereithara e fetolang matla a mochine (rotation) hore e be matla a motlakase (DC). Ha enjene ea DC e tsamaisoa ke motlakase o tobileng, e theha matla a khoheli ho stator ea eona (karolo e emeng ea enjene). Tšimo e hohela le ho leleka makenete ho rotor (karolo e bilikang ea enjene). Sena se etsa hore rotor e fetohe. Ho boloka rotor e ntse e potoloha, commutator, e leng sesebelisoa sa motlakase se potolohang se sebelisa motlakase ho mapheo. Torgue e tsitsitseng e pota-potileng e hlahisoa ka ho khutlisa tsela ea maqhubu a matsoelintsoeke ho potoloha halofo ka 'ngoe.
Li-motors tsa DC li na le bokhoni ba ho laola lebelo la tsona ka nepo, e leng tlhokahalo ea mechini ea indasteri. Li-motors tsa DC li khona ho qala hang-hang, ho emisa le ho khutlela morao. Ena ke ntlha ea bohlokoa bakeng sa ho laola ts'ebetso ea lisebelisoa tsa tlhahiso. Ka tsela e latelang,XBD-4070ke e 'ngoe ea likoloi tsa rona tse tsebahalang haholo tsa DC.
Hoa tšoana le koloi ea DC, rotor ea hona joale (AC) e koahelang matla a motlakase ho matla a mochini (ho potoloha). E ka boela ea sebelisoa e le jenereithara e fetolang matla a mochine (khetho) ho ba matla a motlakase (AC).
Haholo-holo li-motor tsa AC li arotsoe ka mefuta e 'meli. Enjene ea synchronous le enjene ea asynchronous. Ea ho qetela e ka ba mohato o le mong kapa mekhahlelo e meraro. Ka mochine oa AC, ho na le selikalikoe sa maqhubu a koporo (ho etsa stator), e etselitsoeng ho hlahisa matla a khoheli a potolohang. Ha li-winding li tsamaisoa ke matla a motlakase a AC, matla a khoheli, a hlahisa pakeng tsa bona a etsa hore ho be le hona joale ho rotor (karolo ea ho phunya). Hona joale ho hlahisoa matla a eona a khoheli, a hanyetsanang le matla a khoheli a tsoang ho stator. Tšebelisano pakeng tsa masimo a mabeli e etsa hore rotor e bilike. Ka har'a enjene ea asynchronous ho na le lekhalo lipakeng tsa mabelo ao a mabeli. Lisebelisoa tse ngata tsa motlakase tsa ntlo li sebelisa li-motors tsa AC hobane matla a tsoang matlong ke alternating current (AC).
Phapang lipakeng tsa enjene ea DC le AC:
● Lisebelisoa tsa motlakase li fapane. Ha li-motor tsa DC li tsamaisoa ke hona joale ka kotloloho, li-motor tsa AC li tsamaisoa ke hona joale.
● Mechineng ea AC, sephaka se eme ha matla a khoheli a ntse a potoloha. Ho li-motors tsa DC, lihlomo lia potoloha empa matla a khoheli a lula a eme.
● Li-motor tsa DC li ka finyella taolo e boreleli le ea moruo ntle le lisebelisoa tse eketsehileng. Taolo ea lebelo e finyelloa ka ho eketsa kapa ho fokotsa matla a motlakase. Li-motors tsa AC li tsosolosa tšebeliso ea lisebelisoa tsa ho fetola maqhubu ho fetola lebelo.
Melemo ea li-motors tsa AC li kenyelletsa:
● Litlhoko tse tlase tsa motlakase oa ho qala
● Taolo e betere ea ho qala maemo a hona joale le ho potlakisa
● Boikemisetso bo pharaletseng bakeng sa litlhoko tse fapaneng tsa tlhophiso le ho fetola lebelo le litlhoko tsa torque
● Ho tšoarella hamolemonyana le ho phela nako e telele
Melemo ea li-motors tsa DC li kenyelletsa:
● Litlhokahalo tse bonolo tsa ho kenya le ho hlokomela
● Matla a ho qala a phahameng le torque
● Linako tsa karabo e potlakileng bakeng sa ho qala/ho emisa le ho potlakisa
● Mefuta e fapaneng e pharaletseng bakeng sa litlhoko tse fapaneng tsa motlakase
Mohlala, haeba u na le fene ea motlakase ea lapeng, e kanna ea sebelisa enjene ea AC hobane e hokela ka kotloloho mohloling oa motlakase oa ntlo ea hau, e leng ho etsang hore ho be bonolo ho e sebelisa le tlhokomelo e tlase. Likoloi tsa motlakase, ka lehlakoreng le leng, li ka sebelisa li-motor tsa DC hobane li hloka taolo e nepahetseng ea lebelo la koloi le torque ho fana ka boiphihlelo bo bonolo ba ho khanna le ho potlakisa hantle.
