Izici eziyinhloko zokusebenza okuhle kakhulu kwama-motor ahlala njalo amagnethi

Uma kuqhathaniswa nama-motor ajwayelekile angenazo izigaba ezintathu, ama-motor ahambisanayo anomazibuthe angunaphakade anezinzuzo ze-torque ephezulu yokuqala, isikhathi esifushane sokuqala kanye nomthamo omkhulu wokulayisha ngokweqile, okunganciphisa umthamo ofakiwe we-motor yokushayela yemishini ngokuya ngamandla angempela e-shaft, ukonga amandla kanye nokunciphisa ukutshalwa kwezimali ezimpahleni ezihleliwe ngesikhathi esisodwa.
Uma kuqhathaniswa, ukulawulwa kwemoto ehambisanayo nemagnethi ehlala njalo kulula, ijubane linqunywa kuphela yimvamisa, ukusebenza kubushelelezi futhi kuthembekile, futhi akushintshi ngokushintshashintsha komthwalo kanye ne-voltage. Uma sibheka izici zejubane lemoto ehambisanayo nemagnethi ehlala njalo, sinquma ukuthi ukusebenza kwempendulo enamandla yemoto kuhle, kufaneleka kakhulu ekulawulweni kwemvamisa.
Inzuzo yokuthiimoto ehambisanayo yemagnethi engapheliItholakala kakhulu kokubili okuphansi nokuphakeme okubili, okungukuthi, ukulahlekelwa okuphansi kanye nokwenyuka kwezinga lokushisa, amandla aphezulu kanye nokusebenza kahle, okuyilokho kanye abantu abakufunayo ukuze injini isebenze, okunquma nesimo semakethe senjini yamagnetic ehlala njalo.

Ama-motor amagnet ahlala njalo anokulahlekelwa okuphansi kanye nokwenyuka kwezinga lokushisa eliphansi

Njengoba insimu yamagnetic yemoto ehambisanayo yamagnethi ehlala njalo ikhiqizwa omamagnethi abahlala njalo, ngaleyo ndlela kugwenywe ugesi wokuvuselela ukukhiqiza insimu yamagnetic ngokulahlekelwa ugesi, okungukuthi, sithi ukulahleka kwethusi; ukusebenza kwemoto ukusebenza kwerotor ngaphandle kogesi, kunciphisa kakhulu ukuphakama kwezinga lokushisa lemoto, ngokusho kwezibalo ezingaphelele, ezimweni ezifanayo zomthwalo, ukunyuka kwezinga lokushisa kuzoba phansi cishe ngama-20K.

Amandla aphezulu kanye nokusebenza kahle okuphezulu kwama-motor ahambisanayo amagnetic unomphela

Uma kuqhathaniswa nama-motor angahambisani, ama-motor angahambisani amagnetic angunaphakade anenani eliphezulu kakhulu lokusebenza kahle emithwalweni elula, anezinhlobo eziningi zokusebenza kahle kakhulu, kanye nokusebenza kahle okungaphezu kuka-90% ngaphakathi kobubanzi obungu-25% kuya ku-120% wesilinganiso somthwalo. Ukusebenza kahle okulinganiselwe kwama-motor angahambisani amagnet angunaphakade kungafinyelela izidingo zendinganiso kazwelonke yamanje yokusebenza kahle kwamandla ekilasini 1, okungenye yezinzuzo ezinkulu ekongeni amandla uma kuqhathaniswa nama-motor angahambisani.

Ekusebenzeni kwangempela, ama-motor awavami ukusebenza ngamandla aphelele lapho eshayela imithwalo. Isizathu siwukuthi: ngakolunye uhlangothi, abaklami abakhethweni lwemoto, ngokuvamile ngokusekelwe ezimweni zokusebenza zomkhawulo womthwalo ukuze banqume amandla emoto, kanye nethuba lezimo zokusebenza zomkhawulo alivamile kakhulu, ngesikhathi esifanayo, ukuze kuvinjelwe ukushiswa kwemoto ezimweni zokusebenza ezingavamile, umklamo uzoba kude namandla emoto okushiya umkhawulo; ngakolunye uhlangothi, umenzi wemoto ukuze aqinisekise ukuthembeka kwemoto, ngokuvamile ezidingweni zomsebenzisi zesisekelo samandla, futhi ashiye umkhawulo wamandla athile. Ngakolunye uhlangothi, ukuze kuqinisekiswe ukuthembeka kwemoto, umenzi wemoto ngokuvamile uzoshiya umkhawulo wamandla athile ngokusekelwe emandleni adingwa umsebenzisi. Lokhu kuholela ekusebenzeni kwangempela kwemoto, iningi lomsebenzi emandleni alinganisiwe lingaphansi kuka-70%, ikakhulukazi ukushayela abalandeli noma imithwalo yamaphampu, imoto ivame ukusebenza endaweni yomthwalo wokukhanya. Kumoto engahambisani, ukusebenza kahle komthwalo wayo wokukhanya kuphansi kakhulu, kuyilapho imoto ehlala njalo ehambisanayo kamazibuthe endaweni yomthwalo wokukhanya, isakwazi ukugcina ukusebenza kahle okuphezulu.

Isici samandla enjini esihambisanayo sikamagnethi esihlala njalo siphezulu, futhi asihlobene nenani lezigaba zenjini, isici samandla omthwalo ogcwele wenjini siseduze no-1, ngakho-ke uma siqhathaniswa nenjini ehambisanayo, ugesi wayo wenjini uncane, futhi ngenxa yalokho ukusetshenziswa kwethusi le-stator kwenjini kuncane, futhi ukusebenza kahle nakho kuphakeme. Isici samandla senjini ehambisanayo siya ngokuya sehla njengoba inani lezigaba zenjini landa. Ngaphezu kwalokho, ngenxa yesici samandla aphezulu senjini ehambisanayo kamagnethi ehlala njalo, amandla okunikezwa kwamandla (i-transformer) yenjini angancishiswa ngokombono, futhi ngesikhathi esifanayo imininingwane ye-switchgear esekelayo kanye nezintambo ingancishiswa.
