I enei wa, he tino hiahia nga kaiwhaiwhai ki te whakahaere i te Brushless DC (BLDC)
Ka whakatauritea ki te motuka DC tawhito, kua pai ake te mahi o te motuka, kua pai ake te kaha o te kaha, engari he uaua ake te whakamahi. He maha nga hua kei waho i te
papa mo tenei kaupapa.
Hei tauira, he maha nga kaiwhakahaere BLDC iti e mahi pai ana mo nga waka rererangi RC.
Mo te hunga e hiahia ana ki te titiro hohonu atu ki te mana whakahaere o te BLDC, he maha ano nga momo moroiti-whakahaere me etahi atu taputapu hiko mo nga kaiwhakamahi ahumahi, he tino pai nga tuhinga.
I tenei wa kaore ano kia kitea he whakamaarama matawhānui mo te whakamahi Arduino micro-controller mo te mana BLDC.
Ano, mena kei te pirangi koe ki te mahi regenerative braking, ki te whakamahi ranei i te BLDC mo te whakangao hiko, kaore au i kitea he maha nga hua e tika ana mo te whakamahi me nga motuka iti, kaore ano au i mohio me pehea te whakahaere i te kaihanga 3-Phase.
Ko tenei hanganga i te tuatahi i roto i te pakiwaitara e pa ana ki te tatau-
Time, ka mahi tonu ahau i muri i te mutunga o te akoranga.
Ko te whakaaro o te kaupapa ko te whakaatu i tetahi tauira taurite o te waka ranu me te putunga hiko wīra me te regenerative braking.
Ko te motuka i whakamahia i roto i te kaupapa he BLDC iti kua horoia mai i te puku rorohiko kua pakaru.
Ko tenei pukapuka e whakaatu ana me pehea te whakamahi i te Arduino micro-controller me te Hall-
Ka pa ki nga pukoro tuunga i roto i te taraiwa me te aratau braking whakahou.
Kia mahara ko te toro ki oscillisoft he tino awhina, ki te kore he mea nui, ki te whakaoti i tenei kaupapa.
Mena kaore e taea e koe te uru atu ki te waahi, kua taapirihia e au etahi whakaaro mo te mahi me te kore o te waahanga (taahiraa 5).
Ko tetahi mea e kore e whakauruhia e tenei kaupapa ki roto i tetahi motuka motuka ko tetahi mahi haumaru penei i te whakamarumaru o naianei.
Inaa, ko te mea kino rawa atu ka tahuna e koe te motuka HD.
Heoi, ko te whakatinana i te whakamarumaru o naianei me nga taputapu o naianei ehara i te uaua, tera pea ka mahia e au i etahi wa.
Mena kei te ngana koe ki te whakahaere i tetahi motuka nui ake, tena koa taapirihia te whakamarumaru o naianei hei tiaki i to motuka me to ake haumaru.
Kei te hiahia ahau ki te whakamahi i tenei kaiwhakahaere me tetahi motuka nui ka taea te mahi i etahi mahi \'tino\' engari kare ano i a au te mea tika.
I kite ahau i hokona e eBay tetahi motuka 86 W mo te $40 pea.
He kaitono pai te ahua.
He paetukutuku RC ano te ingoa ko \'GoBrushless\' e hoko kete e whakahiato ana i a ratou ake BLDC.
Ehara enei i te utu nui, a he pai te wheako ki te hanga i tetahi.
Kia mahara karekau he pukoro whare mo te motuka kei runga i tenei paetukutuku. Wha!
He mahi nui te tuhi i tenei hanganga.

Koinei anake te pepa i kitea e au e whakaatu ana i te raupapa o te huringa o te wahanga braking regenerative.
He whaihua tenei pepa, he regenerative braking i roto i nga waka hiko, he iti noa nga nama i tarewahia e au, engari ki taku whakaaro kei te he te korero mo te mahi whakaora.
I mahia e au tenei kaupapa me te motini puku kopae recycled na te mea he ngawari ki te haere me te pai ki ahau ki te whakamahi i te miihini iti ngaohiko iti ki te ako i te taura e whakahaerea ana e BLDC kia kaua e raru te haumaru.
I tua atu, ka tino ngawari te whirihoranga aukume o te pukoro hall ma te whakamahi i te mowhiti aukume (rotor)
Mai i te tuarua o enei motuka (Tirohia te Hipanga 4).
Ki te kore koe e hiahia ki te haere ki nga raruraru katoa o te whakauru me te whakatika i te pukoro o te whare (nga taahiraa 5-7)
E mohio ana ahau kei te iti rawa etahi motini puku CD/DVD i hangaia i roto i te Whare Puoko.
Kia taea ai e au te huri i te inertia ki te motini ka hoatu he taumahatanga iti ki a ratou, ka hoatu e ahau nga puku pakeke e 5 ki runga i te motini, ka whakapiri marietia me te kapia iti kaha ka piri ki te motini (
Na tenei i hanga te wira i roto i taku kaupapa taketake).

I tua atu, ka hiahia koe ki te tuarua o taua motini puku pakeke hei tango i te rotor mai i taua motini (
He aukume kei roto).
Hei wehe i te motini, ka mau ahau ki te rotor (runga)
He tohu o te motini ka werohia ki runga i te stator (raro)
He 180 nga nekehanga te wehe o nga wiwiri e rua.
Ehara i te mea ngawari ki te pupuri i te motuka i runga i te takirua kia kore e pakaru.
Ka hiahia pea koe ki te hanga rakau v-
Poraka mo tenei kaupapa.
I keria e ahau he kohao i roto i te mowhiti autō i runga i te miihini kia pai ai te noho ki runga o te motuka.
Mena kaore e taea e koe te whakamahi i te miihini, ka taea e koe te whakatika i te rotor hurihuri i runga i te motuka me te kapia kaha.
Ko nga pikitia 2 me te 3 kei raro nei e whakaatu ana i te roto o tetahi o nga motini kua wetewete ahau.
I te haurua tuatahi kei reira (te rotor) e 8 nga pou (
Aukume i takaia ki te kirihou).
I te haurua tuarua (te stator)
E 12 nga waahi (nga awhi).
Ia o nga wahanga motini e toru e 4 nga mokamoka i te raupapa.
Ko etahi o nga motuka HD e toru nga hononga kei raro, kotahi te whakapiri mo ia wahanga, ko tetahi ko te kopa pokapū o te motuka (
Kei te toru nga waahanga ka tutaki).
I roto i tenei kaupapa, karekau e hiahiatia he tap pokapū, engari ka taea e ia te uru mai i roto i te mana whakahaere kore-puoro (
Ko taku tumanako ka tukuna he tuhipoka mo te mana-kore-kore i tetahi ra).
Mena e wha nga hononga o to motuka, ka taea e koe te tautuhi i te waahanga me te ohmita.
Ko te parenga i waenganui i te tap pokapū me te wahanga ko te haurua o te parenga i waenga i nga wahanga e rua.
Ko te nuinga o nga tuhinga mo nga motini BLDC e pa ana ki te hunga he ahua ngaru o muri te ahua o te arawhata, engari te ahua o te motini puku maama he ahua o muri he rite ki te sine (Tirohia i raro nei).
Ki taku mohio, kei te pai te mahi a te taraiwa ngaru hiko me te ngaru ngaru PWM, ahakoa ka heke te kaha.
Pērā i ngā motopaika BLDC katoa, he mea hanga tenei e toru-wahanga haurua-
Transistor Bridge (
Tirohia nga whakaahua tuarua kei raro nei).
Ka whakamahi ahau i te IC i hangaia e ST Micro (L6234)
Mo te piriti, e mohiotia ana ko te taraiwa motuka.
Ko te hononga hiko o L6234 e whakaatuhia ana i te taahiraa 8.
Ko te whakaahua tuatoru i raro nei e whakaatu ana i te hoahoa hoahoa o te taraiwa motuka me nga waahanga motini e toru.
Kia taea ai te mahi a te motini ki te karaka karaka, ka mahia te pana i roto i te raupapa e whai ake nei (
Ko te reta tuatahi ko te transistor o runga, ko te reta tuarua ko te transistor raro)
: Hipanga 1 2 3 4 5 6 karakakakaraka: CB, AB, AC, BC, BA, CA porotiti karaka: BC, BA, CA, CB, AB, AC enei 6-
Ko te raupapa taahiraa o te tohu 6- Ko te \\\'\\\' he tohu tinana 90 anake mo enei motuka.
No reira, e wha nga wa ka puta te tere hurihuri o ia motuka.
Ko nga raupapa e rua he ahua rite, engari kaore i te rite na te mea mo
te raupapa 6- Hipanga, mo CW, ko te ahunga o naianei i roto i te waahanga he kotahi te ahunga, mo te CCW, he rereke te ahunga o naianei.
Ka taea e koe te kite i tenei ma te whakamahi i te ngaohiko o te pākahiko, hiko hiko ranei ki tetahi waahanga motuka.
Mena ka tono koe i te ngaohiko, ka neke iti te motuka ki tetahi huarahi ka mutu.
Mena ka taea e koe te whakarereke tere i te ngaohiko i runga i te waahanga i tetahi o nga raupapa o runga ake nei, ka taea e koe te huri i te motuka ma te ringa.
He tere rawa te whakaoti o nga whakawhiti me nga microcontrollers i enei huringa katoa, ka huri rau nga wa ia hekona i te wa e rere ana te motuka i te tere tere.
Me mahara ano mena ka tukuna te ngaohiko ki nga wahanga e rua, ka neke paku te motini ka mutu.
Na te mea he kore te taipana.
Ka kite koe i tenei i te whakaahua tuawha i raro nei, e whakaatu ana i te kaha o muri o nga wahanga motuka takirua.
He ngaru hiko tenei.
Ina haere te ngaru i roto i te x-
Shaft, he kore te taipana e whakaratohia ana e tenei wahanga. I roto i te raupapa huringa wahanga BLDC ono-
Step kare i puta.
I mua i te whakahekenga o te taipana i runga i tetahi waahanga, ka huri te hiko ki tetahi atu waahanga huinga.
Ko nga motuka BLDC nui ake ka hangaia e nga pukoro Hall i roto i te motuka.
Mena kei a koe he motuka penei ka taea e koe te peke i tenei taahiraa.
Ano, e mohio ana ahau kei te iti rawa etahi motini puku CD/DVD kua hangaia ki roto i te puoro-Hall.
I te hurihanga o te motuka, e toru nga pukoro o te whare e whakamahia ana mo te rapu waahi, na reira ka mahia te huringa wahanga i te wa tika.
Ko taku motuka HD ka eke ki te 9000 RPM (150 Hz).
I te mea e 24 nga huringa mo ia wira, i te 9000 RPM, ka huri te miihini ia 280 microseconds.
Ko te Arduino micro-controller e mahi ana i te 16 MHz, na ko ia huringa karaka he 0. 06 microseconds.
Kare au i te mohio e hia nga huringa karaka e hiahiatia ana hei whakaiti i te rerenga rerenga, engari ahakoa 100 nga huringa karaka e hiahiatia ana, ara, e 5 nga microhekona mo ia whakahekenga o te rerenga.
Ko nga motuka HD karekau he puoro Hall, na reira me whakauru ki waho o te motuka.
Me whakatika te puoro mo te hurihanga motuka me te whakaatu ki te raupapa o nga pou e rite ana ki te hurihanga motuka.
Ko taku otinga ko te tango i te whakakai autō mai i te motini kotahi, ka whakauruhia ki raro ki runga i te motini hei whakahaere.
Katahi ka utaina e ahau nga pukoro whare e toru ki runga ake i tenei mowhiti autō, 30 nga nekehanga te wehe tetahi ki tetahi i runga i te kaaka motuka (
120 tohu te hurihanga hiko hiko).
Ko taku kaipupuri puoro Hall he putunga ngawari e toru nga waahanga konumohe i tukatukahia e au me nga waahanga kirihou e toru i hangaia i runga i te tauira tere.
Mena karekau enei taputapu, kaua e uaua ki te kimi huarahi kee hei tohu i te tuunga.
Ko te hanga taiapa mo nga pūoko Hall ka uaua ake.
He huarahi tenei hei mahi: 1.
Kimihia he paepae kirihou e tika ana te rahi ka taea e koe te whakapoxy i te pukoro o te whare. 2.
Ka taia he tauira ki te pepa, he rite te porowhita ki te radius mowhiti autō, a ko nga tohu e toru he 15 nga nekehanga 3 te wehenga.
Whakapirihia te tauira ki te kōpae katahi ka whakamahi i te tauira hei kaiarahi ki te whakanoho i te epoxy sensor o te whare.
Inaianei kua whakauruhia nga puoro Hall ki runga i te motini, hono atu ki te ara iahiko e whakaatuhia ana i raro nei ka whakamatau ma te whakamahi i te DMM, i te oscilloscope ranei kia mohio kei te piki haere te whakaputanga i te wa e huri haere ana te motuka.
Ka whakahaerehia e au enei pukoro i raro i te 5 v ma te whakamahi i te putanga 5 v a Arduino.
He teitei, he iti ranei te putanga o te pūoko Hall (1, 0)
Ka whakawhirinaki ki te ahua o te Antarctic, te Arctic ranei.
I te mea he 15 nga nekehanga te wehe, ka huri nga aukume i raro i a raatau ka huri i te polarity ia 45 nga nekehanga, ko enei pukoro e toru e kore e teitei, e iti ranei i te wa kotahi.
I te hurihanga o te motuka, ko te putanga o te puoro he 6-
Ko te tauira taahiraa e whakaatuhia ana i te ripanga e whai ake nei.
Me whakahāngaitia te pūoko ki te nekehanga o te motini kia huri tika tetahi o nga pukoro e toru i te waahi huringa o te wahanga motuka.
I roto i tenei take, ko te taha pikinga o te puoko whare tuatahi (H1)
Me rite ki te whakatuwheratanga o te huinga C (tiketike) me B (iti).
He rite tenei ki te huri i nga transistors 3 me te 5 i te ara iahiko piriti.
Ka whakahāngai ahau i te pūoko ki te aukume ki te oscilloscope.
Ki te mahi i tenei, me whakamahi ahau e toru nga hongere o te whanui.
Ka hurihia e ahau te motini ma te hono ki te whitiki o te motuka tuarua ka ine i te kaha o muri i waenga i nga huinga wahanga e rua (
A me B, A me C)
E rua tenei.
Pērā i ngā ngaru i te pikitia i raro nei
Kātahi ka tirohia te tohu o te pūoko Hall 2 i te hongere 3 o te oscilloscope.
Ka hurihia te kaipupuri o te puoro o te Hall kia tae ra ano ki te whakangao o te taha pikinga o te pukoro o te whare ki te waahi e tika ai te whakarereke i te wahanga (Tirohia i raro nei).
Kei te mohio ahau inaianei e rua noa nga hongere hei mahi i taua whakatikatika.
Mena ko te BEMF o te huinga wahanga B-
Ma te whakamahi i te C, ka hono te tapa piki o H2 ki te pihi BC.
Ko te take e tika ai te whakarereke i te wahanga ki konei ko te pupuri tonu i te taipana motuka kia teitei rawa.
Ko te pumanawa o muri he rite ki te taipana, a ka kite koe ka puta nga huringa o ia wahanga ina pahemo te pumanawa o muri ki raro i te pihi o muri.
Na reira, ko te taipana tuuturu ko te waahanga teitei o ia huinga wahanga.
Ki te kore e taea e koe te uru atu ki te whanuitanga, koinei taku whakaaro mo te tirohanga.
He tino whakaihiihi tenei mo te hunga e hiahia ana ki te mohio ki te mahi a te BLDC Motor.
Mena ka hono te motini Wāhanga A (he pai) me te B (kino)
Ki te hiko hiko ka huri i te hiko, ka huri iti te motini ka mutu.
Na, ki te nekehia te arataki hiko kino ki te wahanga C ka huri te hiko, ka huri atu te motuka ka mutu.
Ko te waahanga e whai ake nei ko te neke i te mata pai ki te Wāhanga B, me etahi atu.
Ina mahi koe i tenei, ka tu tonu te motini ki te kore te taipana, e rite ana ki tetahi waahi ka haere te tūtohi i te tuaka-x i te tūtohi.
Kia mahara ko te ira kore o te huinga tuatoru-waahanga e rite ana ki te waahi huringa o nga huinga tuatahi e rua.
No reira, ko te tuunga taipana kore o B-
Ko te huinga C ko te waahi e hiahia ana koe ki te tuu i te tapa piki o te h2.
Tohua tenei tuunga ki nga tohu pai, ki nga mata koi ranei, katahi ka whakatikahia te pupuri pukoro o te whare ma te whakamahi i te DMM kia tino teitei ake te putanga o te H2 ki runga i tenei tohu.
Ahakoa ka kotiti kee koe i te waarangi o to kura, me pai te mahi o te motuka.
Ko te wahanga motini e toru ka whiwhi mana mai i te taraiwa motika toru-waa L6234.
I kitea e ahau he hua pai tenei ka taea te tu i te whakamatautau o te waa.
He maha nga huarahi hei parai aitua i o waahanga i te wa e whakamahi ana i te hikohiko hiko, ehara ahau i te miihini hiko, kaore au i te mohio he aha nga mahi.
I roto i taku kaupapa kura, i mahia e matou ta matou ake 3-
Wāhanga haurua piriti putanga o te 6 transistors MOSFET me te 6 ngohe.
I whakamahia e matou tenei i runga i te HIP4086 o tetahi atu taraiwa Intersil, engari he maha nga raruraru mo tenei tatūnga
I tahuna e matou he paihere transistors me nga maramara.
Ka rere ahau i te L6234 (
Na te motuka) i te 12V.
Ko te L6234 he huinga whakauru rereke hei whakahaere i te haurua piriti o te 6 transistors.
Ehara i te mea he whakaurunga katoa, engari he
urunga whakaahei (EN) mo ia o nga wahanga e toru, katahi ano he urunga (IN)
Tīpakohia ko tehea transistor i te wahanga tuwhera (runga, raro ranei).
Hei tauira, whakakāhia te transistor 1 (runga) me te 6 (raro)
He teitei te EN1 me te EN3 (
EN2 iti kia kati te atamira)
IN1 Teitei, IN3 iti.
Ma tenei ka hanga te huinga wahanga-C.
Ahakoa i kii te tuhipoka tono L6234 ki te tono i te PWM i whakamahia hei whakahaere i te tere o te motini ki te pine IN, ka whakatau ahau ki te mahi i runga i te titi EN na te mea, i taua wa, ki taku whakaaro he 'ahurei' te huri i nga transistors o runga me raro o te waahanga ''.
Inaa, te ahua nei kaore he he ki te huri i nga waahanga e rua, na te mea he rite tonu te kaha o te huri i nga waahanga e rua.
Ma taku tikanga, ka whakahoehia te waahanga teitei
Ka haere ratou i roto i te naianei.
me te mono i te auau PWM, ka noho tonu te wahanga iti i te huringa o te
wahanga katoa Kei raro nei he hoahoa o te puku motika, kua taapirihia e au
te hononga titi ki te papa Arduino ka
taapirihia e au he 2. 5 amps i waenga

simple that it seems like
a waste to do this task with a microprocessor. In fact, L6234's application notes recommend a simple programmable gate array (
ki te mahi i tenei mahi kaore au i te mohio ki te kaupapa o
GAL16V8 he mea hanga mai i te Lattice Semiconductor)
tenei taputapu, engari ko te utu mo te IC he $2 anake i te Newark He iti rawa atu etahi atu waahanga ko
te whakahiato i nga kuaha arorau ngawari e whakaatu ana i nga wahanga A6 e whakaatu ana i nga wahanga o te IC kei raro, me te ripanga pono mo nga wahanga e toru katoa ( Kia taea ai te iahiko arorau o nga wahanga B me C, me huri te tatau \'kore\' ki tera taha o te \' ranei. Ko te raruraru o tenei huarahi he tata ki te 20 nga hononga i ia wahanga, no reira ka nui te mahi ki te whakakotahi.
