Yintoni umlawuli wemoto yemoto
Isilawuli semoto yeemoto (i-MCU) sisixhobo esiphambili se-elektroniki sezithuthi zamandla amatsha, esiphakathi kwebhetri yamandla kunye nemoto yokuqhuba. Inoxanduva olukhulu lokuguqula umbane ngqo ube ngumbane otshintshanayo ukuze iqhube imoto isebenze, kunye nokulungisa isantya semoto, i-torque kunye necala layo ngokwemiyalelo yokuqhuba, ukufikelela kulawulo lokuqala, ukukhawulezisa, ukuqhobosha, ukunyuka kunye nezinye iimeko zokuqhuba kwemoto.
Umsebenzi oyintloko
Ukuguqulwa kweVolthi ye-Youdaoplaceholder0 : Guqula umbane othe ngqo ukusuka kwibhetri yamandla ube ngumbane otshintshayo wesigaba sesithathu ukuze uqhube i-AC motor. Le nkqubo ifezekiswa nge-inverter yangaphakathi, esebenzisa izixhobo zokutshintsha ze-semiconductor ezifana nee-transistors okanye ii-IGBTs ukulawula i-frequency kunye ne-amplitude yombane.
Isantya kunye nolawulo lwe-torque ye-Youdaoplaceholder0: Lungisa isantya semoto kunye ne-torque ngokweemfuno zokuqhuba (ezifana nendawo yegiya, i-accelerator, i-brake), kwaye ufumane ulawulo oluchanekileyo ngetekhnoloji ye-PWM (i-pulse width modulation).
Ukhuseleko lwenkqubo ye-Youdaoplaceholder0: Ixhotyiswe ngokhuseleko lokugqithiswa kakhulu, ukufunyanwa kweempazamo, ukhuseleko lwesiphelo sokufaka ibhetri kunye nezinye iindlela zokuqinisekisa ukusebenza ngokukhuselekileyo kwenkqubo.
Ukubuyiselwa kwamandla e-Youdaoplaceholder0: Ngexesha lokuqhobosha, amandla e-kinetic anokuguqulwa abe ngamandla ombane ngenkqubo ye-inverter yokutshaja ibhetri, ngaloo ndlela kuphucula uluhlu lokuqhuba.
Izinto eziphambili
Imodyuli yolawulo ye-Youdaoplaceholder0 : Iqhuba imiyalelo yokuqhuba kwaye ivelise imiqondiso ye-PWM ukulawula i-inverter.
Imodyuli yamandla ye-Youdaoplaceholder0 : Iqulethe i-IGBT kunye nezinye izinto zokutshintsha ukuze kufezekiswe ukuguqulwa kwe-voltage.
I-sensor ye-Youdaoplaceholder0 : ijonga imeko yemoto (njengobushushu, isantya) kwaye iyibuyisela kwinkqubo yolawulo.
Inkqubo yokususa ubushushu ye-Youdaoplaceholder0 : igcina ubushushu obusebenzayo obuzinzileyo phantsi kweemeko zomthwalo ophezulu.
Ukusebenza komlawuli wemoto kuchaphazela ngokuthe ngqo amava okuqhuba kunye nokusebenza kakuhle kwamandla kwezithuthi zombane kwaye sisixhobo esiphambili esidibanisa ibhetri yamandla kunye nemoto yokuqhuba.
Umlawuli wemoto yeemoto yinxalenye ebalulekileyo yezithuthi zombane, kwaye imisebenzi yakhe ephambili ibandakanya:
Isantya kunye nolawulo lwe-torque
Isantya semoto kunye ne-torque zilungiswa ngokwemiyalelo efana ne-accelerator kunye ne-brake. I-voltage kunye ne-frequency zilawulwa ngetekhnoloji ye-PWM ukuze kufezekiswe ulawulo oluchanekileyo lwesantya, ukuhlangabezana neemfuno zokuqhuba ezifana nokukhawulezisa, ukuqhobosha, kunye nokuthambeka kokunyuka.
Ukuguqulwa kwamandla kunye nokuqhuba
Umbane othe ngqo ovela kwibhetri yamandla uguqulwa ube ngumbane otshintshanayo ukuqhuba imoto, kwaye icala langoku lilungiswa nge-inverter ukulawula ukujikeleza phambili nokujika kwemoto. Xa kubhuleka, amandla e-kinetic anokuguqulwa abe ngamandla ombane aze abuyiselwe kwibhetri.
Ukukhuselwa kwenkqubo kunye nokuxilongwa kwayo
Jonga iiparameters ezifana nobushushu bemoto kunye ne-voltage, uchonge iimpazamo ngexesha langempela (ezifana nokushisa kakhulu kunye nokugqithisa kakhulu), kwaye uthathe amanyathelo okukhusela ukuthintela umonakalo. Kwangaxeshanye, nxibelelana kwaye wabelane ngedatha nezinye iinkqubo (ezifana ne-BMS) ngenethiwekhi ye-CAN.
Ulawulo lwempendulo oluguqukayo
I-Torque kunye ne-magnetic flux zilungiswa ngokuzimeleyo ngokusebenzisa ii-algorithms zolawulo lwe-vector ukuze kufumaneke impendulo ekhawulezileyo kwimiyalelo yokuqhuba. Utshintsho oluthambileyo ngexesha lokuqala/lokuyeka ukunciphisa imvakalelo yokothuka.
Iimpazamo zomlawuli wemoto kwizithuthi ezintsha zamandla zibonakala kakhulu njengokungasebenzi kakuhle kwamandla, ukuqala nzima, ukusetyenziswa kwamandla okwandileyo kunye nezinye iingxaki. Izizathu ezithile kufuneka zigwetywe ngokupheleleyo kunye neziganeko zempazamo.
