—Ngakho-ke kuphakama umbuzo mayelana nokuthi kusho ukuthini igama elithi 'injini yamagnethi ehlala njalo'. Ihluke ngaziphi izindlela kunjini evamile?
A imoto ye-AC ehlala njalo yemagnethi(PMM) ichazwa njenge-injini kagesiesebenzisa izakhiwo zamagnetic zangaphakathi zamamagnethi ahlala njalo ukukhiqiza insimu yamagnetic edingekayo ekusebenzeni kwayo. Ngokungafani nama-motor avamile, avame ukuthembela ku-electromagnet aqhutshwa ugesi wangaphandle ukukhiqiza insimu yamagnetic, i-PMM isebenzisa amandla amagnetic angaphakathi amamagnethi ahlala njalo. Lo mehluko oyisisekelo ekwakhiweni uveza izinzuzo eziningi ezibalulekile, ikakhulukazi maqondana nokusebenza kahle kanye nokongiwa kwamandla.
Inzuzo eyinhloko yama-motor adonsa unomphela ukusebenza kahle kwawo okuphezulu kanye nekhono lawo lokonga amandla. Ukungabikho kwesidingo samanje esengeziwe sokukhiqizwa kwensimu yamagnetic kubonisa ukwehla okukhulu kokulahlekelwa amandla ngesikhathi sokusebenza, inzuzo ehambisana nama-motor adonsa unomphela. Lokhu kusebenza okuthuthukisiwe kuphumela ekunciphiseni ukusetshenziswa kwamandla, ngaleyo ndlela kwenza ama-motor adonsa unomphela abe inketho ekhangayo yezinhlelo zokusebenza ezahlukahlukene, okuhlanganisa izimoto zikagesi kanye nemishini yezimboni.
Ngokuphambene nalokho, izinjini ezivamile (ezifanai-ac motor yokungenisa kagesis) zithembele ekugelezeni kwamandla kagesi nge-coil ukuze kudalwe insimu yamagnetic. Le nqubo iholela ekulahlekelweni kwamandla ngenxa yokushisa nezinye izici, okunciphisa ukusebenza kahle okuphelele. Ngakho-ke kungaphethwa ngokuthi injini evamile ingadinga ukufaka amandla amaningi ukuze kufezwe izinga elifanayo lokukhipha njengenjini yamagnetic ehlala njalo.
Ngaphezu kwalokho, ukwakheka okubumbene kwama-motor amagnethi ahlala njalo kuvumela ukudalwa kwezilungiselelo zama-motor alula futhi acinene kakhulu, okuyinto ezuzisa kakhulu ekusetshenzisweni lapho isikhala nesisindo kuyizinto ezibalulekile okufanele uzicabangele. Ngaphezu kwalokho, ama-motor amagnethi ahlala njalo avame ukubonisa izici zokusebenza eziphakeme, kufaka phakathi ukuminyana kwe-torque ephezulu kanye nezikhathi zokuphendula ngokushesha.
Umehluko omkhulu phakathi kwenjini yamagnetic ehlala njalo kanye nenjini evamile yindlela ekhiqiza ngayo insimu yamagnetic. Amandla okonga amandla amanjini amagnet ehlala njalo awenza abe ukukhetha okuhle kakhulu kwezicelo eziningi zesimanje, ngokungafani nemiklamo yezimoto yendabuko.
