Kuyini isilawuli semoto yezimoto
Isilawuli semoto yezimoto (i-MCU) siyimojuli eyinhloko ye-elekthronikhi yezimoto ezintsha zamandla, etholakala phakathi kwebhethri lamandla kanye nemoto yokushayela. Inesibopho esikhulu sokuguqula ugesi oqondile ube ugesi oshintshashintshayo ukuze imoto isebenze, kanye nokulungisa isivinini, i-torque kanye nesiqondiso semoto ngokwemiyalelo yokushayela, ukufeza ukulawula ukuqala, ukusheshisa, ukubhuleka, ukukhwela kanye nezinye izimo zokushayela zemoto.
Umsebenzi oyinhloko
Ukuguqulwa kwe-Voltage ye-Youdaoplaceholder0 : Guqula ugesi oqondile ovela ebhethrini lamandla ube ugesi oshintshashintshayo wezigaba ezintathu ukuze ushayele i-AC motor. Le nqubo ifinyelelwa nge-inverter yangaphakathi, esebenzisa amadivayisi okushintshanisa ama-semiconductor afana nama-transistors noma ama-IGBT ukulawula imvamisa kanye nobukhulu bogesi.
I-Youdaoplaceholder0 Isivinini kanye nokulawula i-torque : Lungisa isivinini semoto kanye ne-torque ngokuya ngezidingo zokushayela (njengesikhundla segiya, i-accelerator, ibhuleki), bese ufinyelela ukulawula okunembile ngobuchwepheshe be-PWM (pulse width modulation).
Ukuvikelwa kwesistimu ye-Youdaoplaceholder0 : Ifakwe ukuvikelwa kokulayisha ngokweqile, ukutholwa kwamaphutha, ukuvikelwa kwetheminali yokufaka ibhethri kanye nezinye izindlela zokuqinisekisa ukusebenza okuphephile kwesistimu.
I-Youdaoplaceholder0 Ukubuyiselwa kwamandla : Ngesikhathi sokubhuleka, amandla e-kinetic angaguqulwa abe amandla kagesi ngenqubo ye-inverter ukuze ashaje ibhethri, ngaleyo ndlela kuthuthukiswe ububanzi bokushayela.
Izingxenye ezibalulekile
Imojula yokulawula ye-Youdaoplaceholder0 : Icubungula imiyalelo yokushayela futhi ikhiqize amasignali e-PWM ukulawula i-inverter.
Imojula yamandla ye-Youdaoplaceholder0 : Iqukethe i-IGBT nezinye izingxenye zokushintsha ukuze kufezwe ukuguqulwa kwe-voltage.
Inzwa ye-Youdaoplaceholder0 : iqapha isimo senjini (njengokushisa, isivinini) bese iyibuyisela ohlelweni lokulawula.
Uhlelo lokususa ukushisa lwe-Youdaoplaceholder0 : lugcina izinga lokushisa lokusebenza lizinzile ngaphansi kwezimo zomthwalo ophezulu.
Ukusebenza kwesilawuli semoto kuthinta ngqo ulwazi lokushayela kanye nokusebenza kahle kwamandla kwezimoto zikagesi futhi kuyisikhungo esiyinhloko esixhumanisa ibhethri lamandla kanye nemoto yokushayela.
Isilawuli semoto yezimoto siyingxenye eyinhloko yezimoto zikagesi, futhi imisebenzi yaso eyinhloko ihlanganisa:
Isivinini kanye nokulawula i-torque
Ijubane lenjini kanye ne-torque kulungiselelwa ngokwemiyalelo efana ne-accelerator kanye ne-brake. I-voltage kanye ne-frequency kulawulwa ngobuchwepheshe be-PWM ukuze kufezwe ukulawulwa kwejubane okunembile, kuhlangatshezwane nezidingo zokushayela njengokusheshisa, ukubhuleka, kanye nemithambeka yokukhuphuka.
Ukuguqulwa kwamandla kanye nokushayela
Ugesi oqondile ovela ebhethrini lamandla uguqulwa ube ugesi oshintshanayo ukuze ushayele injini, futhi isiqondiso samandla silungiswa nge-inverter ukulawula ukujikeleza phambili nokuhlehla kwenjini. Lapho kubhuleka, amandla e-kinetic angaguqulwa abe amandla kagesi bese ebuyiselwa ebhethrini.
Ukuvikelwa kwesistimu kanye nokuxilongwa kwayo
Gada amapharamitha afana nokushisa kwemoto kanye ne-voltage, thola amaphutha ngesikhathi sangempela (njengokushisa ngokweqile kanye nokulayisha ngokweqile), bese uthatha izinyathelo zokuzivikela ukuvimbela umonakalo. Ngesikhathi esifanayo, xhumana futhi wabelane ngedatha nezinye izinhlelo (njenge-BMS) ngenethiwekhi ye-CAN.
Ukulawula impendulo enamandla
I-torque kanye ne-magnetic flux zilungiswa ngokuzimela ngokusebenzisa ama-algorithms okulawula i-vector ukuze kufezwe impendulo esheshayo emiyalweni yokushayela. Ukushintsha okushelelayo ngesikhathi sokuqala/sokuma ukuze kuncishiswe umuzwa wokushaqeka.
Amaphutha esilawuli semoto ezimotweni ezintsha zamandla abonakala kakhulu njengokwehla kokusebenza kwamandla, ukuqala okunzima, ukusetshenziswa kwamandla okwandisiwe kanye nezinye izinkinga. Izimbangela ezithile zidinga ukwahlulela ngokuphelele kanye nezimo zamaphutha.
Ukubonakaliswa kwamaphutha okuvamile
Ukwehla kokusebenza kwamandla kwe-Youdaoplaceholder0: I-pedal ye-accelerator iphendula kancane, okwenza kube nzima ngemoto ukusheshisa futhi inciphise isivinini esiphezulu.
I-Youdaoplaceholder0 Ukuqalisa okungajwayelekile : Kungase kube nobunzima ekuqaliseni, imizamo eminingi yokwehluleka ukuqala, noma imisindo/ukudlidliza okungajwayelekile ngesikhathi sokuqalisa.
I-Youdaoplaceholder0 Ukusetshenziswa kwamandla okwandisiwe : Ukwehluleka kwesilawuli kungaholela ekunciphiseni ukusebenza kahle kwemoto kanye nokunciphisa ibanga lemoto.
I-Youdaoplaceholder0 Isibani sesikhombisi sephutha : Iphaneli yethuluzi ikhombisa isibani sephutha sesistimu yamandla noma isibani sephutha sesistimu yemoto.
Indlela yokuxilonga amaphutha
Ukuhlolwa okuyisisekelo kwe-Youdaoplaceholder0 :
Hlola ukuthi i-voltage yokunikezwa kwamandla ijwayelekile yini (sebenzisa i-multimeter ukukala ukuthi i-voltage engu-5V ayijwayelekile yini)
Bheka ukuthi ngabe kukhona yini into eshisa kakhulu kusekethe eyinhloko yesilawuli (amashubhu okushintsha angu-6 e-MOS)
Ukutholwa kwesignali ye-Youdaoplaceholder0 :
Linganisa ushintsho lwe-voltage lapho uphendula isibambo (ububanzi obujwayelekile: 0-4.2VDC)
Hlola ukuthi izintambo zokuxhuma zikhululekile noma zigugile yini
Ukuhlolwa okuhlukile kwe-Youdaoplaceholder0 :
Uma ukumelana kwenqola esunduzayo kunyamalala ngemva kokunqamula imigqa emithathu emikhulu yemoto, kungaba iphutha lomlawuli
Sebenzisa amathuluzi ochwepheshe (njenge-multimeter) ukuhlola amapharamitha anjenge-diode kanye ne-voltage yesibambo
Ukuhlaziywa Kwezimbangela Zamaphutha
Umonakalo wehadiwe ye-Youdaoplaceholder0: Ukuguga noma ukushisa ngokweqile umonakalo kumadivayisi wamandla angaphakathi (njengamamojula e-IGBT)
Inkinga yokuxhumeka kwe-Youdaoplaceholder0 : Imigqa yesignali exegayo negugile iholela ekulahlekelweni kwesignali yokulawula
I-Youdaoplaceholder0 Iphutha lomklamo : ukwakheka kokushabalalisa ukushisa okunganele noma ukucushwa okungenangqondo kwamapharamitha wesekethe
