- I-inverter motor
Ama-inverter motors amamotho asebenzisa ubuchwepheshe be-inverter ukulawula isivinini semoto. Ubuchwepheshe be-inverter busebenzisa okokusebenza kwe-elekthronikhi ukulawula isivinini semoto, ngaleyo ndlela kubone ukulawulwa kwejubane lemoto, amandla nokusebenza kahle kwayo.
Injini yokuguqula imvamisa nge "special frequency induction motor + frequency converter" indlela yokulawula isivinini se-AC eyakhiwe izinga eliphezulu lokuzishintsha kwemishini yemishini yemoto, le nhlanganisela ithathe indawo ngokuphelele yokulawula isivinini komshini kanye nohlelo lokulawula isivinini se-DC; ngobuchwepheshe bamandla kagesi, ubuchwepheshe be-microelectronics, ukuthuthukiswa okumangalisayo kokusetshenziswa kwe-Ngokuthuthuka okumangalisayo kobuchwepheshe bamandla kagesi, ubuchwepheshe be-microelectronics, ukusetshenziswa "kwe-special frequency induction motor + converter frequency" yemodi yesivinini se-AC, nokusebenza kwayo okuhle kakhulu. kanye nomnotho, emkhakheni wokulawula isivinini ukuhola esikhundleni sendlela evamile yejubane yesizukulwane esisha soshintsho.
Ngenxa yokulawulwa kwesivinini se-inverter motor kanye nokulawula ekuphakameni okungenakuqhathaniswa, ukuze izinga lokuzenzakalelayo komshini kanye nokukhiqiza lithuthuke kakhulu; Ukunikezwa kwamandla kwe-EPS njengomkhuba wesikhathi esizayo wokuthuthukiswa kobuchwepheshe be-inverter futhi ngaleyo ndlela inomsebenzi wayo, kodwa ngenxa yesistimu ye-inverter motor yokusebenza ngesivinini esiphezulu noma esiphansi, isivinini sokujikeleza kokuphendula okuguquguqukayo nezinye izidingo zomzimba oyinhloko. we-motor kagesi njengamandla okubeka phambili izidingo ezinzima zizonikezwa ku-inverter motor izolethwa ku-inverter motor. Ku-electromagnetic, ukwakheka, ukwahlukanisa nezinye izici zokuqamba izinto ezintsha. Kungashiwo ukuthi ngenxa yokuphakama kwe-inverter motor ekulawuleni imvamisa phezu kwama-motor ajwayelekile, nomaphi lapho kusetshenziswa i-converter frequency akunzima ukubona isibalo se-inverter motor.
- I-Industrial Frequency Motors
Amamotho emvamisa yezimboni abhekisa kumamotha e-AC ashayelwa ngokuqondile kusetshenziswa imvamisa yensiza (imvamisa engu-50Hz noma engu-60Hz) njengomthombo wamandla, futhi ngokuvamile asetshenziswa kwezinye izinhlelo zokusebenza ezinembayo, ezinesivinini esiphansi, nezinesidingo esiphansi. Izinzuzo zama-motor frequency motors yisakhiwo esilula, ukuthembeka okuphezulu kanye nezindleko eziphansi, kodwa okubi ukuthi isivinini ne-torque kunzima ukulawula nokulungisa, futhi ukunemba kuphansi, akufanelekile izinhlelo zokusebenza ezinezidingo zokulawula ukunemba okuphezulu.
Emkhiqizweni wesimanje wezimboni, ngokuthuthuka okuqhubekayo kwekhwalithi yomkhiqizo kanye nezidingo ezisebenza kahle, izinhlelo zokusebenza eziningi zidinga ukunemba okuphezulu nokusebenza kokulawula, ngakho-ke i-inverter motor ithathe indawo ye-industrier frequency motor njengeyona ehamba phambili. Ama-inverter motors angakwazi ukulawula isivinini kanye ne-torque ye-motor ngokusebenzisa isiguquli semvamisa, athuthukise ukusebenza kahle nokunemba kwemoto, futhi afanele uhla olubanzi lwezinhlelo zokusebenza.
- Umehluko phakathi kwe-inverter motor kanye ne-industrial frequency motor
I-inverter motor kanye ne-industrie frequency motor ingumehluko obaluleke kakhulu phakathi kokuhlukahluka kokunikezwa kwamandla okubili, amandla kagesi embonini kanye nemvamisa ayishintshile, kuyilapho i-voltage yokufaka kanye nemvamisa ye-inverter motor iyashintsha, kungenxa yalesi sici, esimiselwe izimo zokusebenza ze-inverter motor zibe nzima, ngakho-ke ezicini ezifanele zomzimba wemoto, kuyadingeka ukuthatha izinyathelo ezidingekayo ukuze kuvinjelwe inqubo yokusebenza kwezimoto Izinkinga zekhwalithi zenzeka.
I-inverter motor inikwa amandla yi-inverter, okukhiphayo okuvela ku-inverter akuyona i-non-sinusoidal rectangular waveform, i-harmonics ephezulu ekhiqizwa yi-inverter inomthelela omkhulu ekusebenzeni kwemoto, ama-harmonics aphezulu azodala ukusetshenziswa kwe-motor stator yethusi, ukusetshenziswa kwethusi kwe-rotor. , ukusetshenziswa kwensimbi kanye nokulahlekelwa okwengeziwe kwanda, okubaluleke kakhulu ukusetshenziswa kwe-rotor yethusi. Ngenxa yokwanda kokulahlekelwa, umphumela oqondile kakhulu ukukhuphuka kwezinga lokushisa lemoto.
Ngenxa yalezi zizathu ezingenhla, inverter motor winding insulation structure uma kuqhathaniswa ne-frequency motor kuzoba nomehluko othile: izinga lokufakwa kwe-inverter motor kufanele okungenani libe yizinga elilodwa eliphakeme kunama-motor ajwayelekile, njengama-motor frequency iningi le-insulation yezinga B, futhi ama-inverter motors okungenani ngokuya nge-F level insulation design, ngaphezu komehluko phakathi kwezinto zokufakelwa, ezihambisana nomugqa we-electromagnetic nazo zizoba nomehluko:
(1) Ibanga elikwazi ukumelana nokushisa locingo lwe-electromagnetic motors inverter kufanele lihambisane nesakhiwo sokufakwa kwama-windings, futhi likhethwe ngokuya ngebanga elingekho ngaphansi kuka-155.
(2) I-electromagnetic wire yama-inverter motors kufanele ikhethwe njengocingo olukhethekile lwe-electromagnetic, umehluko phakathi kwalolu hlobo lwezintambo zikagesi kanye ne-electromagnetic wire ejwayelekile isekucacisweni kwe-varnish evikelayo, engagwema ukukhishwa kwento kanye nenkinga yokushisisa. i-insulating medium, engaqinisekisa ngempumelelo ukusebenza okuphephile kwama-inverter motors futhi yandise impilo yesevisi yamamotho.
Ekusetshenzisweni kwangempela, abanye abakhiqizi bezimoto ku-inverter motor winding ene-varnish ewugqinsi kagesi kagesi, bangadambisa ngempumelelo imbangela yephutha elijikayo, kodwa abakwazi ukuxazulula inkinga ngokuyisisekelo. Ngakho-ke, kusukela ekuhlaziyweni kwezici ezibalulekile ze-inverter motor, ukusetshenziswa kwe-inverter ekhethekile yocingo lwe-electromagnetic, kungaxazulula ngempumelelo ukumelana nokushisa futhi kuvimbele ukuvela kwezinkinga ze-corona.
