Abahlinzeki bedivayisi yempendulo yamandla bakukhumbuza ukuthi amamotho alawula isivinini esishintshashintshayo, esifushanisiwe njengamamotho amafrikhwensi aguquguqukayo, igama elivamile lamamotho ashayelwa iziguquli zefrikhwensi. Inzuzo yabo ukuthi banomsebenzi wokuqala; Ukwamukela umklamo we-electromagnetic kunciphisa ukumelana kwe-stator ne-rotor; Ukujwayela ukuguquguquka njalo ngaphansi kwezimo ezihlukene zokusebenza; Ngokwezinga elithile, yonga amandla. Njengamanje, isiphenduke isikimu sokulawula isivinini esivamile futhi singasetshenziswa kabanzi ezimbonini ezihlukahlukene zokudlulisela okuguquguqukayo okuqhubekayo.
(1) Ukusabela kwamamotho anesivinini esikhulu kuncane, futhi ama-harmonics e-oda eliphezulu azokhuphula inani lamanje. Ngakho-ke, lapho ukhetha i-frequency converter yama-motor anesivinini esikhulu, umthamo wesiguquli semvamisa kufanele ube mkhulu kancane kunalowo wamamotho ajwayelekile. Lapho i-GD2 yesistimu yokushayela ingashintshi, ububanzi besivinini samamotho anesivinini esikhulu bubanzi, futhi isikhathi esidingekayo sokusheshisa/ukunciphisa side kakhulu. Ngakho-ke, isikhathi sokusheshisa/sokwehlisa kufanele simiswe sibe side kancane.
(2) Uma isiguquli sefrikhwensi sisetshenziselwa i-pole motor eguquguqukayo, singasetshenziswa lapho ijubane lejubane lesiguquli sefrikhwensi libanzi, kodwa ukunaka okugcwele kufanele kukhokhwe ekukhetheni umthamo wesiguquli sefrikhwensi ukuze isilinganiso esiphezulu samanje senjini sibe ngaphansi komphumela wamanje olinganiselwe wesiguquli sefrikhwensi. Ngaphezu kwalokho, lapho ushintsha inombolo yezigxobo ngesikhathi sokusebenza, sicela umise injini kuqala. Uma ukushintsha kwenziwa ngesikhathi sokusebenza, kungase kubangele ukuvikeleka kwe-overvoltage noma ukuvikelwa kwe-overcurrent ukusebenza, okuholela ekulimaleni kwemoto kanye nokulimala okukhulu kwesiguquli sefrikhwensi.
(3) Uma ushayela izinjini ezingaqhumi, isiguquli sefrikhwensi kufanele sibekwe ngaphandle kwezindawo eziyingozi noma ngaphakathi kwezindawo ezivikela ukuqhuma ngenxa yokuntuleka kwezakhiwo ezingaqhumi.
(4) Uma usebenzisa isiguquli sefrikhwensi ukushayela injini yokunciphisa igiya, ububanzi bokusetshenziswa bukhawulwa indlela yokugcoba yezingxenye ezijikelezayo zegiya. Ngesivinini esiphezulu ngaphezu kwejubane elilinganiselwe, kunengozi yokuphelelwa uwoyela wokugcoba, ngakho-ke isivinini esiphezulu esivumelekile akufanele sidlule. Kufanele kuqashelwe futhi umsindo okhiqizwa amagiya.
(5) Lapho isiguquli sefrikhwensi sishayela i-rotor yesilonda e-asynchronous motor ngesikhathi sokusebenza, ngenxa yokuphazamiseka okuphansi kwe-rotor yesilonda engavumelaniyo ne-asynchronous motor, ukukhubeka ngokweqile okubangelwa i-ripple current kujwayele ukwenzeka. Ngakho-ke, isiguquli semvamisa esinomthamo omkhulu kunokuvamile kufanele sikhethwe. Ngokuvamile, ama-motor asynchronous motors avame ukusetshenziswa ezimweni lapho i-flywheel torque GD2 inkulu, futhi kufanele kuqashelwe ukulungiselelwa kokusheshisa/ukunciphisa isikhathi.
(6) Uma ushayela i-synchronous motor, umthamo wokuphumayo uzokwehla ngo-10% uma uqhathaniswa nokunikezwa kwamandla okuvama kwamandla. Okukhiphayo okuqhubekayo kwamanje kwesiguquli sefrikhwensi kufanele kube kukhulu kunomkhiqizo wamanje olinganiselwe wenjini ehambisanayo kanye nenani elijwayelekile le-synchronous traction current.
(7) Ngemithwalo ene-torque enkulu eguquguqukayo njengama-compressor nama-vibrator, kanye nemithwalo ephakeme kakhulu njengamaphampu adonsa amanzi, uma isiguquli semvamisa sinqunywa ngokusekelwe enanini elilinganiselwe lamanje noma lamandla enjini, kungenzeka isenzo sokuvikela esidlulele ngenxa yezinga eliphezulu lamanje. Indlela engenzeka iwukubona i-waveform yamanje ngesikhathi sokusebenza kwemvamisa yamandla bese ukhetha isiguquli sefrikhwensi esinomphumela wamanje olinganiselwe omkhulu kunomkhawulo wamanje wamanje.
(8) Uma ushayela injini yepompo ye-submersible nge-converter yefrikhwensi, igagasi elilinganiselwe lesiguquli sefrikhwensi kufanele libe likhulu kunaleso senjini yepompo engaphansi kwamanzi ngenxa yokuthi isilinganiso sayo samanje siphezulu kunesenjini evamile.
(9) Amamotho esigaba esisodwa awafanele ukushayela ngeziguquli zefrikhwensi. Uma usebenzisa i-capacitor based single-phase motor, i-capacitor ingase yonakaliswe ngenxa yomphumela wamanje we-high-frequency current.
Ngesikhathi sokusebenza kwesistimu yokulawula isivinini esishintshashintshayo, amanye amaphutha angase abangwe injini. Ngakho-ke, ngaphezu kokuhlola i-converter ye-frequency, kuyadingeka futhi ukuhlola ukuthi isixhumanisi ngasinye se-motor sijwayelekile. Kufanele futhi kuqashelwe ukugcinwa kwezinjini zikagesi emsebenzini wansuku zonke.
