Ukuxhuma motor ezintathu okhombisa

Ngo ubunjiniyela kagesi, kunezindlela ezimbili ezilula zokuxhuma motor ezintathu okhombisa ukuphi. Ziyakwazi ngokuphongoza nomunye, futhi Ukukhetha kwabo kuncike kule mibandela yokusebenza injini hlobo.

Uhlobo lokuqala isebenzisa ezintathu okhombisa motor uxhumano ngokuthi "unxantathu." Ihilela Windings stator ochungechungeni uxhumano. Eqinisweni, ekupheleni kokuqala motor izinkampani exhunywe kwi-yesibili. Lolu hlobo uxhumano kudinga nesenzakalo ephezulu sokuqala imisinga futhi ivumela injini ukunikeza ephelele nameplate umthamo.

Uhlobo uxhumano yesibili ibizwa ngokuthi "inkanyezi". Lapho uyisebenzisa, kube semikhawulweni Windings axhunyiwe ndawonye phezulu yabo futhi akukhuthalele. uxhumano okunjalo ezintathu okhombisa motor umnene ngaphezulu, kodwa injini ikhiqiza amandla kancane nohafu kunangesikhathi ohlanganisa "unxantathu".

Inhlanganisela ezifanele kakhulu ubhekwa uxhumano. It isetshenziswa ngokuyinhloko yamandla aphezulu izinjini, kodwa ubuye efanelekayo izimo zokuphila, njengoba kuvikela injini kusuka ukuminyana ezingadingekile, futhi ngesikhathi esifanayo inikeza amandla aso agcwele, njengoba sishiwo encwadini iphasiphothi. Iqala injini ngokusebenzisa uhlobo uxhumano "inkanyezi". Nokho, ngeke usakubona imithwalo esindayo imisinga okusezingeni eliphezulu. Ngemva ijubane ifinyelela kwenani eliyimali, it is bashintshele emazombezombe uhlobo "unxantathu", okusho kuyaqhubeka kuze kube sekupheleni komsebenzi. Lokhu uxhumano kuhilela ukusetshenziswa ezintathu okhombisa motor isikhathi inkinobho noma ukuziqalela ekhethekile.

Endaweni ehlukile, kuyafaneleka ukuthi iningi izinjini omubi basabela voltage nokushintshashintsha noma nesifunda esincane. Ngakho-ke, imiklamo le ezintathu okhombisa motor uxhumano, ngokuvamile iketanga zihlanganisa fuses noma wonke izindlela zokuzivikela.

Kaningi, abantu abaningi babhekana nesimo lapho isitokwe has a motor ezintathu okhombisa, futhi inethiwekhi kagesi ine isigaba esisodwa kuphela. Ezimweni ezinjalo, sebenzisa uxhumano ezintathu okhombisa motor esigabeni inethiwekhi olulodwa ukusetshenziswa capacitors. Zikuxhuma nge esibulalayo khulula emazombezombe futhi ixhunywe kwinethiwekhi. Kufanele ikhumbule yokuthi capacitance capacitor kufanele yehluke kuye ngesistimu inani injini linemibhikisho. Ngakho-ke, axhunyiwe parallel komunye nomunye ngendlela yokuthi lapho kokubili capacitors abangu ushintshele inethiwekhi, futhi ngokufaka ijubane yokusebenza ye capacitor wesibili kumele inqanyuliwe.

Ngakho-ke, lapho ezintathu okhombisa motor uxhumano yenziwe wesifunda owodwa esigabeni, capacitor, njalo egijima, ngokuthi abasebenzi, kodwa onenhliziyo icishiwe, ngokuthi isibangeli. Kulesi ukuziqalela capacitor capacitance kufanele kube cishe kathathu kunenani zokusebenza. Qala capacitor ixhunyiwe nge inkinobho ehlukile, esiqhutshwa okukhishwayo injini ngejubane ecacisiwe.

Kuyaphawuleka ukuthi kule uxhumano injini ilahlekelwa ezingaphezu kuka-60% umthamo wayo, futhi uma ixhunywe usebenzisa "inkanyezi", nokulahlekelwa okunjalo kungase kwandise ngenye ingxenye. Ngakho-ke, ezimweni ezinje kunconywa ukusebenzisa uhlelo "unxantathu" emandleni ukulahlekelwa ziyancipha.
