Ko te tikanga whakangao tohu motika motuka korekore me te hanga tere

Ka tere te whakaputa i te maapono me nga hanganga,

te tikanga hoahoa i runga i te tauira ma te Mathworks he raupapa taputapu, ka taea te whakatutuki tika mai i te ariā hoahoa ki te tauira algorithm, katahi ka hangaia aunoa e te tauira o te tukanga whanaketanga pai o te waehere whakauru. Mo tenei tauira, i runga i te maramara LPC2124 ki te whakatutuki i te mana motopaika kore (刷)Te ahua o te huringa, kaore nga kaihoahoa e whai whakaaro me pehea te motuka i roto i te reo C, te reo huihuinga ranei, me aro noa ki te algorithm ano, ki te whakaoti i te mahi whakangao waehere whakaraerae ki te rorohiko. Ka taea e tenei te whakapoto i te huringa whanaketanga hua, te whakapai ake i te pai o te mahi. 1 maataapono tātaritanga o brushless dc motopaika mahi waiho te iahiko whakakā hiko, na te ontology i te motopaika, rotor tūnga pūoko me te hiko whakakā iahiko o toru nga wahi, te brushless dc motopaika pūnaha whakahaere, tona hoahoa hoahoa e whakaaturia i roto i te ahua 1. Dc mana supply mana ki te nekeneke stator awhiowhio i roto i te ara iahiko whakakā, pūoko tūnga kitea te tūnga rotor i nga wa katoa, me te rite ki te ahua o te rere o te hau, te hiko o te waka rererangi, me te tohu o te hiko o te hau ki te whakahaere i te hiko. e whakahaere aunoatia ana e te mate hiko, ka whakatinana i te whakawhiti hiko.

whakaahua 1 te ahua o te punaha whakahaere motopaika korepu i raro iho nei
i roto i te motini paraihe awhiowhio toru-waahanga hei tauira, he kupu whakataki poto mo tana maapono mahi. Whakaatu 2 mo te toru-waahanga piriti puku katoa hoahoa ara iahiko iahiko, me te tikanga o rua puku hiko noa ki tona, te hiko awhiowhio rua i te wa ano. E ono nga wahanga toru-waahanga hiko i roto i te ahua o nga transistors, diodes, Ha, Hb, Hc mo te tohu tuunga rotor mo te huānga o te whare o te urupare. Ka whakatauhia te ara iahiko mana kia rite ki te tohu tuunga 6 tohu tohu huarahi PWM i runga me te atu, e hanga ana i te whakahaerenga ngongo hiko ka tutakina atu ranei, ko te kawe awhiowhio i roto i tetahi ota, motika puku hurihuri tonu.
i te wa e whakamahi ana i nga motuka e rua nga waahanga kawe, ko te ngongo hiko o te ahuatanga i muri i te huringa 1/6 (whakahaere i runga, i runga ranei i te 60 & deg; ）。 Kua whakauruhia ki roto o te motuka dc brushless e toru nga tuunga o te whare, he rereke i runga i te waahi & 120 deg; 180 & deg;


由
A和C的合磁场产生的转矩使转子转动到AC位置。 Ko te hurihanga o te rotor ki te huri i te putanga o te pūoko hall, ka whakatika iahiko mana whakahaere ngongo, ka rere atu te motini ki te V6, i tenei wa ka rere te whakaahua mai i te V5 motini, ko te papa aukume i hangaia e te ahunga awhiowhio ko (A，B）。 由A和B的合磁场产生的转矩使转子转动到AB位置。 Waihoki, ka taea e te taputapu whakahaere te whakaputa i tetahi waahanga rereke.
