Brushless dc hanganga mana nekeneke me te hiranga

Brushless dc motini mana whakahaere me te hiranga o



o brushless dc motini mana whakahaere brushless dc motor he ahua o te motini tukutahi, ara, te tere rotor motopaika o te tere motini hurihuri papa autō o te stator me te pou rotor (P)F/P. Mena ka whakatauhia te maha o te rotor, ka huri te auau o te papa hiko hurihuri ka taea te whakarereke i te tere o te rotor. Brushless dc motor ko te pūkaha tukutahi ki te mana hiko (Drive), whakahaere i te auau o te stator hurihuri mara autō me te pūkaha rotor tere urupare ki te pokapū mana o te whakatika toutou, i roto i te tikanga ki te whakatutuki tata ki te ara nga āhuatanga o te nekeneke dc. Arā, ka taea e te motini dc brushless kei roto i te taumahatanga kua whakatauhia ka taea tonu e nga huringa uta te pupuri i te tere tere rotor motuka. Ko nga taraiwa dc kore-paraihe tae atu ki te tari hiko me te tari whakahaere e whakaatuhia ana i te ahua (1): ko te mana hiko e whakarato ana i nga waahanga hiko e toru-waahanga ki te motini, te motuka, te hiko o te hurihanga hiko o te tari whakauru whakauru e rite ana ki nga whakaritenga.

brushless dc motopaika hiko ka taea te hono tika ki te urunga dc (Te tikanga mo te 24 v) I roto ranei i te urunga o naianei tauutuutu (110V/220 V)Me uru ki te tuatahi, mena ko te whakauru he kaitahuri o naianei. Ko te whakaurunga dc, te whakauru ac ranei hei huri ki te motini motuka me noho i mua i te ngaohiko dc e te inverter (inverter)Kia toru nga wahanga ngaohiko hei peia nekeneke. Kaihuri hiko dc Brushless (inverter)Ma te ono hiko hiko (te nuingaQ1～Q6)Wehea ki te ringa o runga (Q1和Q3, Q5)/ ringa raro,Q2、Q4、Q6)Kua hono atu ki te motini i te wa e rere ana te mana whakahaere i roto i te whakakoi porohita motuka. Ko te tari whakahaere motuka dc Brushless e whakarato ana i te PWM (Pulse width modulation) Te whakatau i te kaha whakawhiti whakawhiti whakawhiti me te inverter (inverter)Ko te wa o te whakawhiti. Ko te motuka dc Brushless e hiahia ana ki te whakamahi i roto i te tere ka taea te pumau i roto i te uara ka kore te huringa o te kawenga e huri i te mana tere, na reira ka taea e te motuka te whakauru i te papa autō o te pukoro hall kua whakauruhia ki roto (大厅-传感器) Ka rite ki te tere katia te mana o te porowhita, me te wa ano ko te kaupapa o te mana raupapa wahanga. Engari ka whakamahia noa hei whakahaere tere, kaore e whakamahia hei huinga o


nga painga o te motuka dc brushless dc motor he tere te whakautu, he nui te tiimata o te tiimata, te tere hurihuri mai i te kore ki te tere reiti ka taea te whakarato i te mahi taipana whakatau, engari ko nga painga o te motuka dc brushless he hokinga, na te miihini dc brushless ki te whakaputa i te taipana mau tonu, me te mau tonu o te mara autō9, i raro i te waahi o te miihini kua whakatauhia. & deg; Kua tata ki te nama mai i te paraihe waro me te commutator. Ko te paraihe waro me te hurihanga nekeneke ka puta he korakora, paura waro, no reira ka kino nga waahanga, ka aukatia te whakamahi. Ac motor kahore paraihe waro me te commutator, tiaki kore utu, kaha, tono whānui, engari ki te āhuatanga ki te whakatutuki rite ki te mahi o te brushless dc nekeneke me whakamahi hangarau mana matatini ki te whakatutuki. I enei wa ko te whanaketanga tere o te waahanga semiconductor e huri ana i te kaha o te kaha ki te tere ake i te tini, te whakapai ake i te mahi o te motuka taraiwa. Ko te Microprocessor he tere ake, ka taea te mohio ki te mana o te motuka ac e rua i runga i te hurihanga i roto i te punaha taunga tapawhā, te whakahaere tika o te waahanga hiko ac i roto i nga tuaka e rua, he rite ki te mana motuka dc me te mahi o te motuka dc he tino pai. He maha ano hoki nga miihini whakahaere miihini miihini e hiahiatia ana mo te mahi i roto i te maramara, me te iti o te riipene me te iti ake; Hei kaitahuri tairitenga/mamati (模拟,-数字转换器ADC)Me te whakahuringa whanui puihi (脉宽调制器,PWM)…A pera tonu. Ko te motuka dc kore-paraihe e whakahaere hiko ana i te whakawhiti nekeneke ac me nga momo umanga penei i nga ahuatanga motuka dc kore-paraihe me te kore motika dc i runga i te kore tono.
