Te mana korekore o te tuunga motini dc brushless

Sensorless brushless dc motor i roto i te mana o te tūnga
i roto i te brushless dc motor, induction hiko hiko i roto i stator awhiowhio me te rotor tūnga mau tonu tetahi hononga, rite ki ' Tikanga o hoki emf ' Commutation o te brushless motopaika dc i runga i te parau tumu o te mahi. A ko te kaha kaha o te hiko hiko o te whakaurunga he rite ki te tere o te motuka. Ko te tere tere hurihuri ranei i te wa e tino iti ana te motuka, he kore, he iti rawa ranei te kaha o te kaha hiko hiko o te whakauru, kaore i whakamahia hei whakatau i te waahi o te pou o te rotor, na reira kaore e taea e te tiimata o te miihini dc brushless te huri i runga i te kaha hiko hiko.
i roto i te tikanga ki te whakarite i te tikanga noa o te motini brushless dc taea tīmata, Me tuatahi koe ki te whakatau i te tūnga o nāianei o te rotor, i raro i te huru o te kawenga marama, me te ra o te trapezoidal bemf waveform brushless dc nekeneke he tikanga WHAKAMAHI te autō frein moto tūnga rotor. I timata te punaha ki te hiko, tetahi huinga o te pupuhi whakaoho, i hangaia i roto i te hau hau te kaha kaha, te ahunga o te rere tonu, te miihini korepu, kia mohio he nui te kaha o tona kaha, kia taea ai te rere o te aukume i roto i etahi waa ka kaha te tuunga o te motuka motuka ki tenei huarahi.
engari, no te mea o te rangirua o te okiokinga nekeneke rotor tūnga, ki te i mua i te kimi i tona tūranga, te tūnga tika i roto i te kawe VT1 me VT6, waka rererangi tauira, nekeneke stator awhiowhio hiato rere autō d o Fa me rotor rakau Koki he 180 nekehanga, e kore e te nekeneke rotor takahuri ki te tūranga, rahunga takotoranga. Hei whakaoti i tenei rapanga, ka taea te whakamahi ' E rua karapīpiti ' Tikanga Turanga. Ka rite ki whakaaturia i roto i te runga ake, i runga i te turanga o te tūranga tuatahi, ka whakahaere i te āhua i muri mai, pērā i te kawe VT1 me VT2, he angitu kore ranei, ahakoa mo te wa tuatahi me angitu te tūranga tuarua.
