Ko te miihini dc brushless moroiti, nga kaiwhakarato kounga miihini kore

Ka whakatauritea ki te motika o naianei me te motika asynchronous, ko te hangarau matua o te motuka dc brushless e tohuhia ana e:

1, te mana hiko mo nga taonga whakahaere motika dc, penei i te pai ake o te whakahaere, te whanui tere.

2, me nga korero urupare tuunga rotor me te puku hiko hiko polyphase inverter.

3, tino, ac motor, ki kahore he korakora o te paraihe me te commutator, kakahu raruraru, te moroiti brushless dc nekeneke, Ka taea te mahi i te tere tiketike, ka taea te whiwhi pono nui, te roa o te ora mahi, me kore e maha tiaki.

Ko te 4, te kaha teitei o te miihini dc korepu (BLDCM), te rotor ngaro me te kirikaa, he pai ake te kaha: te rereke o nga raraunga, 7. 5 kw te kaha o te motika asynchronous he 86. Te kaha o te 4%, me te kaha o te miihini dc brushless ki runga ki te 92. 4%.

5, me whai waahanga mana hiko, he nui ake te utu katoa i te motuka dc. Ko te motini matua e whakamahia ana i roto i te punaha korero e rua nga momo miihini whakauru me te motuka tukutahi aukume tuturu, kia rite ki te kaupapa mahi o te momo rereke o te miihini tukutahi aukume tuuturu, ka taea te wehea ki te ngaru o muri emf o te miihini tukutahi aukume pumau (永磁同步电动机) Na te ngaru tapawha ki muri emf maataapono o naianei, he rereke te mana o te motopaika emf me te mana o naianei. e kore e rite.

sinusoidal aukume tuturu synchronous motor counter electromotive kaha ko tetahi momo o te sinusoid, ki te hanga nekeneke taipana maeneene, brushless dc motor, nekeneke awhiowhio o naianei rere me hoki tauira sinusoidal, me mohio koe e te tohu tūnga rotor tonu, ka taea e te inverter whakarato nekeneke ngaohiko hiko o naianei ranei, na reira, katoa-mamati fuzzy hiahia ki te tango i te tūnga o te taumira teitei e hurihanga uaua hoki.

Ko te kaha o te hiko hiko he trapezoidal brushless dc motor (BLDCM), i te mea he papatahi te whakaurunga tapawha-ngaru nekeneke awhiowhio me te taipana, dongguan brushless motor, no reira, te waahi o te BLDCM e kore e hiahiatia he pūoko taumira teitei, he ngawari te taputapu urupare, he ngawari te whakahaere algorithm. I tua atu i te BLDCM trapezoidal ngaru hau-aputa papa autō he nui atu i taua o te katoa-mamati fuzzy sine ngaru rangi-aputa papa autō i runga i te whakamahi o te matua rino he teitei; A he teitei ake te BLDCM i te kiato hiko puhoi-mamati katoa, he nui ake te taipana whakaputa mo ia roopu roopu. Na te tono o te aukume pūmau brushless dc nekeneke me te rangahau aro nui atu.
