- I-inverter motor
Iimotor eziguquguqukayo ziimotor ezisebenzisa itekhnoloji yokuguqula ukulawula isantya semoto. Itekhnoloji ye-inverter isebenzisa izixhobo zombane ukulawula isantya semoto, ngaloo ndlela iqonda ulawulo lwesantya semoto, amandla kunye nokusebenza kakuhle.
Ukuguqulwa kwemoto rhoqo nge "imoto ekhethekileyo yokungeniswa kwemoto + isiguquli esijikelezayo" indlela yokulawula isantya se-AC eyenziwe ngumgangatho ophezulu wokuzitshintsha komatshini wezixhobo zemoto, olu luhlu luthathe indawo yolawulo lwesantya soomatshini kunye nenkqubo yokulawula isantya seDC; Ngobuchwepheshe bombane we-elektroniki, itekhnoloji ye-microelectronics, uphuhliso olumangalisayo lokusetyenziswa kwetekhnoloji yombane, itekhnoloji ye-microelectronics, ukusetyenziswa kwe "imotor ekhethekileyo yokungenisa i-motor + frequency frequency converter" yemowudi yesantya ye-AC, kunye nokusebenza kwayo okugqwesileyo kunye noqoqosho, kwibala lolawulo lwesantya ukukhokela ukutshintshwa kwemowudi yesantya yemveli yesizukulwana esitsha sotshintsho.
Ngenxa yolawulo lwesantya semoto ye-inverter kunye nolawulo ekuphakameni okungenakuthelekiswa nanto, ukwenzela ukuba inqanaba lokuzenzekelayo komatshini kunye nemveliso kuphuculwe kakhulu; Ubonelelo lwamandla e-EPS njengekamva lophuhliso lobuchwepheshe be-inverter kwaye ngenxa yoko inobungcali bayo, kodwa ngenxa yenkqubo ye-inverter motor yokusebenza ngesantya esiphezulu okanye esisezantsi, isantya esijikelezayo sokuphendula okuguquguqukayo kunye nezinye iimfuno zomzimba ophambili wemoto yombane njengamandla okubeka phambili iimfuno eziqatha ziya kunikwa i-inverter motor iya kuziswa kwi-inverter motor. Kwi-electromagnetic, ulwakhiwo, ukugquma kunye neminye imiba yokuqalisa izinto ezintsha. Kunokuthiwa ngenxa yokuphakama kwe-inverter motor kulawulo lwamaza kwiimoto eziqhelekileyo, naphi na apho i-converter frequency isetyenzisiweyo asikho nzima ukubona umzobo we-inverter motor.
- IiMoto eziphindaphindayo kwishishini
Iimotor ze-Industrial frequency motors zibhekisa kwiimotor ze-AC eziqhutywa ngokuthe ngqo usebenzisa i-frequency ye-utility (idla ngokuba yi-50Hz okanye i-60Hz) njengomthombo wamandla, kwaye zihlala zisetyenziselwa ukuchaneka okuphantsi, isantya esiphantsi, kunye nesicelo esisezantsi. Iingenelo ze-industrial frequency motors ziyisakhiwo esilula, ukuthembeka okuphezulu kunye neendleko eziphantsi, kodwa ukungonakali kukuba isantya kunye ne-torque kunzima ukulawula nokulungelelanisa, kwaye ukuchaneka kuphantsi, akufanelekile kwizicelo ezineemfuno zokulawula ngokuchanekileyo.
Kwimveliso yale mihla yemizi-mveliso, ngokuphuculwa okuqhubekayo komgangatho wemveliso kunye neemfuno ezisebenzayo, ngakumbi nangakumbi izicelo zifuna ukuchaneka okuphezulu kunye nokusebenza kolawulo, ngoko ke i-inverter motor iye ngokuthe ngcembe yathatha indawo yemotor frequency yeshishini njengeyona iphambili. Iimotor ze-inverter zinokulawula isantya kunye ne-torque ye-motor nge-converter frequency, ukuphucula ukusebenza kunye nokuchaneka kwemoto, kwaye ilungele uluhlu olubanzi lwezicelo.
- Umahluko phakathi kwe-inverter motor kunye ne-industrial frequency motor
I-inverter motor kunye ne-industrial frequency motor ngowona mahluko usisiseko phakathi kokubini ukwahluka kobonelelo lwamandla, i-industrial frequency motor input voltage and frequency ayiguquguquki, ngelixa i-voltage yegalelo kunye ne-frequency ye-inverter motor iyatshintsha, kungenxa yale nto, imiselwe ukuguqula imeko yokusebenza kweemoto ukuba ibe rhabaxa, kwaye ngenxa yoko kwimiba efanelekileyo yomzimba wemoto, kuyafuneka ukuba uthathe amanyathelo omgangatho wokusebenza kwemoto ukuthintela ukwenzeka kweengxaki.
I-inverter motor inikwe amandla yi-inverter, imveliso evela kwi-inverter yi-non-sinusoidal rectangular waveform, i-harmonics ephezulu eveliswa yi-inverter inempembelelo enkulu ekusebenzeni kwemoto, i-harmonics ephezulu iya kubangela ukusetyenziswa kwe-motor stator yobhedu, ukusetyenziswa kobhedu lwe-rotor, ukusetyenziswa kwentsimbi kunye nelahleko eyongezelelweyo, eyona nto ibalulekileyo kukusetyenziswa kobhedu lwe-rotor. Ngenxa yokwanda kwelahleko, eyona siphumo sithe ngqo kukunyuka kobushushu bemoto.
Ngokubhekiselele kwezi zizathu zingasentla, i-inverter motor winding insulation structure xa kuthelekiswa ne-frequency motor kuya kubakho umahluko: inqanaba lokugquma i-inverter motor kufuneka libe linqanaba elinye ngaphezulu kuneemotor eziqhelekileyo, ezinje ngeemotor frequency uninzi lwe-insulation level B, kunye ne-inverter motors ubuncinci ngokwe-F level insulation design, ukongeza kumahluko phakathi kwezixhobo zokugquma, ezihambelana nomgca we-electromagnetic nazo ziya kuba nomahluko:
(1) Ibakala elimelana nobushushu locingo lwe-electromagnetic kwiimotor eziguquguqukayo kufuneka lihambelane nesakhiwo sokugquma ii-windings, kwaye zikhethwe ngokwenqanaba elingekho ngaphantsi kwe-155.
(2) I-electromagnetic wire yeemotor inverter kufuneka ikhethwe njengocingo olukhethekileyo lwe-electromagnetic, umahluko phakathi kolu hlobo locingo lwe-electromagnetic kunye nocingo oluqhelekileyo lwe-electromagnetic lusebume be-varnish ekhuselayo, enokuthi ithintele into yokukhutshwa kunye nengxaki yokufudumeza okuphakathi kwe-insulating, enokuqinisekisa ngokufanelekileyo ukusebenza ngokukhuselekileyo kobomi benkonzo ye-motor inverter.
Kwisicelo sokwenyani, abanye abavelisi beemoto kwi-inverter motor winding kunye ne-varnish engqingqwa yocingo lwe-electromagnetic, banokudambisa ngokufanelekileyo unobangela wempazamo, kodwa abanakuyisombulula ingxaki. Ke, ukusuka kuhlalutyo lweempawu eziyimfuneko ze-inverter motor, ukusetyenziswa kwe-inverter ekhethekileyo yocingo lwe-electromagnetic, kunokusombulula ngempumelelo ukumelana nobushushu kunye nokuthintela ukwenzeka kweengxaki ze-corona.
