- 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 be-elektroniki yamandla, itekhnoloji ye-microelectronics, uphuhliso olumangalisayo lokusetyenziswa Ngophuhliso olumangalisayo lwetekhnoloji ye-elektroniki yamandla, itekhnoloji ye-microelectronics, ukusetyenziswa "kwemotor ekhethekileyo yokufaka i-motor + frequency converter" yemowudi yesantya ye-AC, kunye nokusebenza kwayo okugqwesileyo. kunye noqoqosho, kwintsimi yolawulo lwesantya ukukhokela ukutshintshwa kwendlela 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; Unikezelo lwamandla e-EPS njengekamva lophuhliso lwetekhnoloji ye-inverter kwaye ngenxa yoko inobungcali bayo, kodwa ngenxa yenkqubo ye-inverter motor yokusebenza ngesantya esiphezulu okanye esisezantsi, isantya sokujikeleza kwempendulo eguqukayo kunye nezinye iimfuno zomzimba ophambili. yemoto yombane njengamandla okubeka phambili iimfuno eziqatha ziya kunikwa kwi-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-industry frequency motor ngowona mahluko usisiseko phakathi kokubini ukwahluka kobonelelo lwamandla, amandla ombane okufakelwa kwimizi-mveliso kunye neefrikhwensi aziguquguquki, ngelixa igalelo lombane kunye nokuphindaphinda kwemoto yokuguqula iyatshintsha, kungenxa yale nto, imiselwe Iimeko zokusebenza kwe-inverter motor kufuneka zibe mbi kakhulu, kwaye ngenxa yoko kwimiba efanelekileyo yomzimba wemoto, kuyimfuneko ukuthatha amanyathelo ayimfuneko ukuthintela inkqubo yokusebenza kweemoto Iingxaki zomgangatho zenzeka.
I-inverter motor inikwe amandla yi-inverter, imveliso evela kwi-inverter ayiyo-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 kwe-rotor. , ukusetyenziswa kwentsimbi kunye nokulahleka okongeziweyo kwanda, eyona nto ibaluleke kakhulu 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: i-inverter motor insulation level kufuneka ibe kwinqanaba elinye eliphakamileyo kuneemotor eziqhelekileyo, ezinje ngeemotor frequency most of the B level insulation, kunye iimotor inverter ubuncinci ngokwenqanaba loyilo lwe-insulation, 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) Ucingo lwe-electromagnetic lweemotor eziguquguqukayo kufuneka lukhethwe njengocingo olukhethekileyo lwe-electromagnetic, umahluko phakathi kolu hlobo locingo lwe-electromagnetic kunye nocingo oluqhelekileyo lwe-electromagnetic lusebume bevarnish ekhuselayo, enokuthintela ukukhutshwa kunye nengxaki yokufudumeza. i-insulating medium, enokuqinisekisa ngokufanelekileyo ukusebenza okukhuselekileyo kwee-motor inverter kunye nokwandisa ubomi benkonzo yeenjini.
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.
