Fetoha Reluctance Motor Magnets


Enjene ea ho tsilatsila e fetotsoeng ke mofuta o ikhethileng oa enjene eo rotor e nang le lipara tse ngata tsa palo, para e 'ngoe le e' ngoe e na le makenete le ho tsilatsila. Li-motors tsa ho tsilatsila tse fetotsoeng hangata li sebelisoa lits'ebetsong tse hlokang torque e phahameng le ts'ebetso e phahameng, joalo ka likoloi tsa motlakase le li-drive tsa indasteri.

Mocheng o fetotsoeng oa ho tsilatsila, limakete hangata ke limakete tse sa feleng 'me li sebelisetsoa ho theha matla a khoheli a sa feleng. Magneto-resistors li entsoe ka lisebelisoa tsa makenete tse laoloang ke motlakase oa motlakase ho lokisa matla le tataiso ea matla a khoheli. Ha hona joale e feta ka ho tsilatsila, matla a makenete a ho tsilatsila a eketseha, a theha matla a khoheli a matla a hohelang makenete ho tsilatsila ho haufi le eona. Ts'ebetso ena e etsa hore rotor e bilike, e tsamaisang enjene.

Makenete o bapala karolo ea ho hlahisa matla a khoheli a sa feleng mochining oa ho tsilatsila o fetotsoeng, 'me ho tsilatsila ho fetola matla le tataiso ea matla a khoheli ho laola ts'ebetso ea enjene.

Molao-motheo oa ts'ebetso oa motlakase o fetotsoeng oa ho tsilatsila

Enjene ea ho tsilatsila e fetotsoeng (Switched Reluctance Motor, SRM) ea koloi ea motlakase e na le sebopeho se bonolo. Stator e nka mohaho o tsitsitseng oa ho pota-pota, ha rotor e se na maqhubu. Sebopeho sa enjene ea ho tsilatsila e fetotsoeng le enjene ea ho hatakela li batla li tšoana, 'me ka bobeli li sebelisa matla a khoheli (Max-well force) lipakeng tsa mecha ea litaba e fapaneng tlasa ts'ebetso ea matla a khoheli ho hlahisa torque ea motlakase.

Stator le rotor ea switched reluctance motor e entsoe ka silicon sheet laminations mme e nka sebopeho se setle sa palo. Lipalo tsa stator le rotor tsa motlakase oa ho tsilatsila o fetotsoeng li fapane, 'me stator le rotor li na le li-cogging tse nyenyane. Rotor e entsoe ka tšepe e phahameng ea makenete e se nang likhoele. Ka kakaretso, rotor e na le lipalo tse peli tse ka tlase ho stator. Ho na le mefuta e mengata ea li-stators le li-rotor, tse tloaelehileng ke sebopeho sa li-stator tse tšeletseng le li-rotor tse 'nè (6/4) le sebopeho sa li-stator tse robeli le li-rotor tse tšeletseng (8/6).

Switched reluctance motor is a type of speed control motor developed after DC motor and brushless DC motor (BLDC). The power levels of the products range from a few watts to hundreds of kw, and are widely used in the fields of household appliances, aviation, aerospace, electronics, machinery and electric vehicles.


E latela molao-motheo oa hore matla a khoheli a lula a koaletsoe tseleng ka matla a khoheli a maholo ka ho fetesisa, 'me a hlahisa matla a khoheli ho theha torque-reluctance electromagnetic torque. Ka hona, molao-motheo oa eona oa sebopeho ke hore ho tsilatsila ha potoloho ea makenete ho lokela ho fetoha ka hohle kamoo ho ka khonehang ha rotor e potoloha, kahoo mochine oa ho tsilatsila o fetotsoeng o amohela sebopeho sa lipalo tse peli, 'me palo ea lipalo tsa stator le rotor e fapane.

Potoloho e laolehang e fetohang ke converter, e etsang potoloho e kholo ea matla hammoho le phepelo ea motlakase le moea oa motlakase. Sesebelisoa sa boemo ke karolo ea bohlokoa ea enjene ea ho tsilatsila e fetotsoeng. E lemoha boemo ba rotor ka nako ea sebele mme e laola mosebetsi oa converter ka tlhophiso le ka katleho.

Enjene e na le torque e kholo ea ho qala, e nyane e qalang hona joale, matla a phahameng a matla le torque inertia ratio, karabelo e matla e potlakileng, ts'ebetso e phahameng ka lebelo le pharalletseng, 'me e khona ho lemoha taolo ea li-quadrant tse 'ne habonolo. Litšobotsi tsena li etsa hore enjene ea ho tsilatsila e fetotsoeng e tšoanelehe haholo bakeng sa ts'ebetso tlas'a maemo a fapaneng a ts'ebetso ea likoloi tsa motlakase, 'me ke mohlala o nang le bokhoni bo boholo har'a likoloi tsa likoloi tsa motlakase. Mochini o fetotsoeng oa ho tsilatsila o sebelisa lisebelisoa tsa makenete tse sebetsang hantle haholo ho 'mele oa enjene o fetotsoeng, e leng ntlafatso e matla sebopehong sa enjene. Ka hona enjene e hlola mefokolo ea ho tsamaea butle le ts'ebeliso e tlase ea matla ho li-SRM tsa setso, mme e eketsa bongata ba matla a enjene. Enjene e na le torque e kholo, e molemo haholo bakeng sa ts'ebeliso ea eona ho likoloi tsa motlakase.
