Motors ke e 'ngoe ea lisebelisoa tsa motlakase tse tloaelehileng bophelong ba letsatsi le letsatsi. Phapano ke efe pakeng tsamefuta e fapaneng ea maqhubu a motlakasele li-motor tse tloaelehileng tsa indasteri?
Li-motors ke lisebelisoa tsa motlakase tse itšetlehileng ka molao-motheo oa induction ea motlakase ho lemoha matla a motlakase le phetisetso. Mosebetsi oa eona o ka sehloohong ke ho hlahisa torque e le mohloli oa matla a motlakase kapa a mochini.
Li-motors tse tloaelehileng'me li-motor tse fapaneng tsa maqhubu ka bobeli ke li-asynchronous motors. Molao-motheo oa eona oa ts'ebetso: Ho tsoelipana ha stator ea enjene ke matsoelintsoeke a mekhahlelo e meraro a lekanang sebakeng. Ha motlakase oa AC oa mekhahlelo e meraro o kenngoa ho stator winding, matla a khoheli a potolohang a tla thehoa ka hare ho motlakase. Matla ana a khoheli a potolohang a fokotsa matsoelintsoeke a rotor, ka hona a hlahisa moea o ts'oarellang matsoelineng a rotor. Rotor e tsamaisang hona joale e tla hlahisa matla a motlakase tlas'a ts'ebetso ea stator e potolohang matla a khoheli, ka hona e khanna koloi ho potoloha.
Li-motor tsa frequency tse feto-fetohang le li-motor tse tloaelehileng tsa indasteri Li-motor tse tloaelehileng li atile haholo, empa melemo ea li-motor frequency tse fapaneng ha li bapisoa le li-motor tse tloaelehileng ke life?
- Li-motor tse feto-fetohang li ka sebetsa ka maqhubu a tlase haholo le li-voltage. 'Me li ka qalisoa ntle le tšusumetso ea hona joale. Mekhoa e fapaneng ea braking e fanoeng ke inverter e ka sebelisoa bakeng sa braking e potlakileng ho fihlela ho qala le ho qhoma khafetsa. Hobane li-motor frequency tse fapaneng li ka fihlela ts'ebetso e boima haholo le maemo a sebetsang a thata ho feta li-motor tse tloaelehileng. Ka hona, li-motors tsa maqhubu a feto-fetohang li na le maemo a phahameng a ho ts'oaroa ho feta li-motor tse tloaelehileng tlhahisong, lits'ebetso tsa ho pholisa tse qobelloang (li-fan tse pholileng tse hahelletsoeng), matla a matla a mochini sebopeho, li-rotor bearings le bophelo bo bolelele ba ts'ebeletso ho feta li-motor tse tloaelehileng.
- Joalokaha bohle re tseba, li-motors tse tloaelehileng li ka sebetsa feela tlas'a boemo ba50 Hz maqhubu a matla. Haeba mefuta e fapaneng ea maqhubu e le kholo haholo, enjene e tla chesa haholo kapa e chese enjene. Leha ho le joalo, li-mothara tse feto-fetohang li ka fetola lebelo la enjene ka lebelo lefe kapa lefe ka har'a lebelo ntle le tšenyo. Tlas'a maemo a tloaelehileng, li-motor frequency tse fapaneng li ka sebetsa li sa khaotse ka har'a lebelo le lekantsoeng ka mojaro o lekantsoeng ka botlalo, 'me ho phahama ha mocheso oa koloi ho ke ke ha feta boleng ba ho lekanya koloi.
- Leha li-motors tsa frequency tse fapaneng li theko e tlase hanyane ho feta li-motors tse tloaelehileng ka theko, melemo ea tsona e hlakile haholo. Mokhoa oa taolo ea lebelo la AC oa frequency converter hammoho le enjene ea frequency frequency e ka ntlafatsa haholo boemo ba boits'oaro ba mochini le katleho ea tlhahiso. Ntle le moo, ts'ebetso e bonolo ea ho qala ea converter ea frequency e boetse e fokotsa ts'usumetso ea motlakase o moholo ho marang-rang ha li-motors tse tloaelehileng li qala, 'me li boloka matla a mangata ho feta li-motor tse tloaelehileng.
Ha litheko tsa li-frequency converters le li-motor frequency li ntse li theoha, ts'ebeliso ea li-motor tse feto-fetohang e tla ba kholo le ho feta.
