Abahlinzeki beyunithi yamabhuleki bakukhumbuza ukuthi kokubili iziguquli zefrikhwensi namamotho kungamadivayisi kagesi anamandla amakhulu. Lapho okwamanje kugeleza kumjikelezo, ngenxa yokuba khona kokumelana, ngokusho komthetho kaJoule, bazokhiqiza imiphumela yokushisa futhi bakhiqize ukushisa. Imisinga yamandla aphezulu ivamise ukuba namandla amakhulu uma kuqhathaniswa, futhi kuzoba khona into ethile yokushisa. Ngokuvamile, kwahlulelwa ukuthi isandla asizizwa sishisa. Uma kushisa kakhulu, kufanele kubhekwane nakho ngesikhathi.
Naka ukunemba kokukhetha
Injini iyinhliziyo yokusebenza kwemishini kanye nomthombo wamandla cishe wayo yonke imithwalo. Lapho uklama ukukhethwa kwemishini, kuyadingeka ukuthi ucabangele ngokuphelele i-torque namandla adingwa umthwalo, ukuze ukhethe amandla emoto afanele kanye ne-torque. Uma umthamo wemoto ukhethwa omncane kakhulu, ulingana nehhashi elincane elidonsa imoto esindayo. Yiqiniso, injini ngokwayo isebenza esimweni esigcwele kakhulu futhi izokhiqiza ukushisa okukhulu.
Ngokufanayo, uma ukucaciswa kwesiguquli se-frequency kuphinde kukhethwe ukuthi kube kuncane, isiguquli semvamisa sisazokhiqiza ukushisa okunzima uma sidlula emisinga ephezulu kuneyamanje elinganiselwe isikhathi eside, futhi izinkinga zizokwenzeka ngokushesha futhi zishise.
Ukukhetha kuncane kakhulu, ngakho-ke singakwazi ukufaka imodeli enkulu kuphela ukuze sibhekane nayo. Lena imfuneko eqinile futhi asikho isinqamuleli. Kumele kusetshenzwe ngesikhathi esifanele. Noma ungayiqaqa le ekhona bese uyidayisa njengesekeni, kungcono uqhubeke nokuyisebenzisa. Phela uma kunezinkinga ezibambezela ukukhiqiza noma zidale ukuqhuma noma ukusha ngenxa yokushisisa nezinye izinto, kukhulu lokho.
Eminye imithwalo ingase ingabonakali inzima, kodwa ihilela ukuqala nokumisa njalo, okudinga nokukhulisa amandla ukuze kusetshenziswe, ngaphandle kwalokho basazobhekana nezinkinga ezishiwo ngenhla.
Izinkinga zemishini nokulayisha
Uma kukhona ukungahambi kahle emishinini eyimishini noma umthwalo, njengamagiya noma ama-bearings omshini wokudlulisa wonakaliswa, ukumelana kuzokwanda futhi okuphumayo kwenjini nakho kuzokhuphuka. Kwezinye izimo ezibucayi, ukumiswa kwemoto kungase kwenzeke, futhi umsinga uzoba phezulu kakhulu. Nakuba iziguquli eziningi zefrikhwensi zizobangela ukugcwala nokudlula ngokweqile, okuholela ekuvaleni kwe-alamu, zikhona futhi ezimweni ezibucayi, noma uma imingcele yokuvikela yesiguquli sefrikhwensi ingasethwanga kahle, isengadala izenzakalo ezingavamile ezifana nokushisisa. Kulesi simo, yiqiniso, sidinga ukuqala ngemishini yemishini kanye nemithwalo yokuxazulula inkinga.
Isibonelo, isiguquli sefrikhwensi silawula amanye amaphampu adlulisa uketshezi noma amafeni okuhambisa umoya. Ngenxa yamapayipi angcolile noma agobile, ukumelana okuphezulu kungabangela amandla amanje ngokweqile kusiguquli se-motor ne-frequency. Lezi zidinga ukuhlanzwa futhi ziphathwe ngesikhathi.
Izinkinga ngesiguquli sefrikhwensi kanye nenjini ngokwayo
Uma i-motor isetshenziswa isikhathi eside, ayikwazi ukukhishwa ukuthi ukusebenza kwe-insulation kumpofu noma ama-bearings anamathele, okungabangela ukukhiqiza okuphezulu kwamanje nokushisa. Ukuxhumana phakathi kwemoto nomthwalo kungase kugqokwe, noma injini ingase ibe nokungalingani kwezigaba ezintathu, izinto zokulungisa okuxekethile zenjini, njll., okungabangela umsindo nokushisa okungavamile.
Ukuguga kwezingxenye ezithile kusiguquli se-frequency, ukuchezuka phakathi kwamapharamitha e-vector nokumataniswa kwemoto, ukusetha okweqile kwamapharamitha njengokukhushulwa kwe-torque, ukusheshisa okufushane kanye nesikhathi sokwehla, kanye nemvamisa ephansi yesithwali yesiguquli sefrikhwensi konke kungabangela isiguquli senjini kanye nemvamisa ukuthi kushise ndawonye.
Intambo yokuxhuma phakathi kwenjini nesiguquli sefrikhwensi akufanele ibe yinde kakhulu, ngaphandle kwalokho izodala ukuncishiswa nokuhlanekezeka kwe-waveform. Uma idinga ukusetshenziswa, isiguquli sefrikhwensi esizinikele kanye ne-reactor eyengeziwe kufanele futhi kusetshenziswe ukuyiphatha.
Kwezinye izimo lapho kudingeka khona ukubhuleka ngokushesha, kubalulekile ukukhetha ama-resistors ama-braking afanelekile namayunithi okubhuleka ngokwamandla okubhuleka.
Umsebenzi wesikhathi eside esimweni se-low-frequency
Ngokuvamile akunconywa ukuklama injini ukuthi isebenze ngaphansi kwe-8HZ, ngisho neziguquli zefrikhwensi ezilawulwa yi-vector, ukusetshenziswa okunjalo kufanele kugwenywe ngangokunokwenzeka. Lokhu kubangelwa ikakhulukazi ukuhlanekezela okunamandla kwe-waveform kumaza aphansi, aqhelelene kakhulu ne-sine wave, okuholela ekusebenzeni kabi kwemoto, ukuncishiswa kwetorque okunzima, kanye nokukhiqizwa kokushisa. Ithagethi ingafinyelelwa ngokwandisa isilinganiso sokudlulisela bese ukhuphula imvamisa yokuphumayo yesiguquli sefrikhwensi.
Uma kudingekile ukuthi usebenze endaweni ephansi-imvamisa isikhathi eside, i-motor frequency frequency ingasetshenziswa, noma injini ingapholiswa ngokupholisa umoya okuphoqelekile noma ukupholisa amanzi.
Lungiselela indawo yokusetshenziswa
Esikhathini esidlule, ngenxa yezimo zezomnotho ezimbi, izimboni eziningi ezincane azizange zenze amakamelo okulawula azimele. Ngisho noma babenamakamelo okulawula, babengawafaki umoya opholile emakamelweni okulawula. Manje njengoba izimo zizinhle, kungenzeka ngokuphelele ukufaka iziguquli zemvamisa nezinye izakhi kuzilawuli ezine-air conditioning. Ngale ndlela, izinga lokushisa lesiguquli semvamisa sisesimweni saso esifanele, okwenza kube mancane amathuba okuthi likhiqize ukushisa nokwelula impilo yaso yesevisi ngenxa yothuli oluncishisiwe nezinye izici. Sekukonke, empeleni kuwutshalomali oluhle uma kuqhathaniswa.
