Ungayenza kanjani ibhayisekili kagesi enenjini yokuqalisa

Embonini yamabhayisekili kagesi, le moto ngokuvamile ibhekisa enhlanganweni yezimoto, kufaka phakathi isikhungo sezimoto, isinciphisi, njll. Ibhayisekili kagesi esilisho ngezansi konke libandla likagesi.

(1) Ukuhlukaniswa kwezimoto

Ngaphambi kokususa imoto, izintambo ezihola phambili zemoto nokulawula kufanele zidlule kuqala. Ngalesi sikhathi, ukurekhoda kokuxhumana ngakunye phakathi kombala wokuhola wemoto nombala wokuhola wesilawuli kumele kuqoshwe. Hlanza indawo osebenza kuyo ngaphambi kokuvula isembozo sokugcina se-motor ukuvikela isundries ukuthi ingangenwa amandla kazibuthe ngaphakathi emotweni. Maka isikhundla sokulinganisa se-cap cap ne-hub. Qaphela: qiniseka ukukhulula izikulufa ngendlela ye-diagonal ukugwema ukuguqulwa kwezindlu zezimoto. Igebe elingangemisebe phakathi kwe-rotor ne-stator yemoto libizwa ngokuthi i-air gap, kanti negebe lomoya wemoto jikelele liphakathi kuka-0.25-0.8mm. Ngemuva kokususa imoto ukuze ususe iphutha lemoto, qiniseka ukuthi ulandela umaki wokuqala wesembozo somhlangano, ukuvikela into yokuhlanza ngemuva komhlangano wesibili.

(2) Ukwebiwa kwamagiya emotweni

Uma kukhona ibhulashi eline-gear hub motor ne-brushless ene-gear hub motor egijima umsindo uqala ukwanda, noma ushintshe igiya kule moto, kufanele ngabe yonke indawo yezinyo segiya ihlanganiswe ngegrisi, ngokuvamile ungasebenzisi u-no. 3 i-grease noma i-oyili ekhethiwe yokuthambisa uwoyela.

(3) Umhlangano wezimoto

Ngaphambi kokuhlanganisa umshini wokuxubha, sicela ubheke ukuqina kwentwasahlobo ngaphakathi kwesiphathi samabhulashi, hlola ukuthi ngabe ibhrashi le-kabhulashi ne-ibhulashi lokuphatha kuyachithwa yini, hlola ukuthi ibhrashi le-carbon lingakufinyelela yini ukushaywa okuphezulu kwesibambi samabhulashi, futhi unake ukuma okulungile kwebhulashi yekhabhoni kanye noshintsho lwesigaba, ukuze uvikele ibhulashi elibi noma i-brashi grip.

Lapho ufaka i-motor, ukungcola okukhona ezingxenyeni zezimoto kufanele kuhlanzwe kuqala, ukuze kungathinti ukusebenza okujwayelekile kwale moto, futhi nomzimba wesondo le-wheel hub kumele ulungiswe ngokuqinile, ukuze ungabangeli ukushayisana nokulinyazwa izingxenye ngenxa yokuheha okuqinile kwensimbi kazibuthe ngesikhathi sokufakwa. Hlola i-36V evamile, ukuphuma kwesilawuli 5V, 12V okwejwayelekile, ukumelana kwemoto okujwayelekile. Xhuma imoto ngqo ibhethri le-36V, futhi imoto isebenza ngokujwayelekile.

(4) Indlela ye-wiring

Ngenxa yokuhamba okuhlukile, ama-motor angenamabhulashi nawama-brushless hhayi kuphela anezakhiwo ezihlukile zangaphakathi, kodwa futhi abe nomehluko omkhulu kwimodi yokuxhuma.

Indlela ye-1.Wiring ye-brashi motor. I-Brashi motors ngokuvamile ine-plus or minus lead. Ngokuvamile, umugqa obomvu uyigxobo elihle lemoto, kanti ulayini omnyama uyigxobo elibi lemoto. Uma i-wiring ye-pole, ne-negative switch engasebenzi kahle, izokwenza ukuthi imoto ibuye emuva, ngokuvamile ngeke ilimaze imoto.

2.Brushless motor isigaba Angle isahlulelo. Isigaba-Angle semoto eyi-brushless isifinyezo sesigaba se-algebraic Angle semoto eyi-brushless. Ama-angles wesigaba esijwayelekile sama-algebraic angles we-brushless motor asetshenziswa ezimotweni zikagesi angama-120 ° no-60 °.

Bheka indawo yokufaka yendawo yehholo ukwahlulela isigaba se-Angle motor brushless. Isikhala sokufakwa kwesakhiwo sehholo sika-120 ° no-60 ° isigaba se-Angle motor sihlukile.

Linganisa isibonakaliso sehholo langempela ukwahlulela isigaba se-Angle of motor brushless

Okudingeka kuchazwe kuqala yilokho okubizwa nge-brushless motor magnetic tension Angle. Ama-motor angenamabhulashi ngokuvamile anezingcezu eziyi-12, 16 noma eziyi-18 zensimbi kazibuthe, kanye nezigcawu ezihambisanayo zama-slator zingama-36, 48 noma i-54 Slots. Lapho imoto isaphumule, umugqa wamandla kazibuthe wensimbi kazibuthe onenimpawu yokuhamba ohlangothini lokungabaza okuncane, ngakho-ke isikhundla lapho insimbi kazibuthe ye-rotor ime khona yindawo yesigxobo se-stvex slot. Amandla kazibuthe awami emgodini we-stator, ngakho-ke kukhona kuphela izikhundla ezingama-36, 48 noma 54 phakathi kwe-rotor ne-stator. Ngakho-ke, ukungezwani okuncane okuphathelene nozibuthe kwe-Angle ye-brushless motor yi-360/36 °, 360/48 ° noma i-360/54 °.

Isakhiwo sehholo lemoto eyi-brushless motor has lead 5, okuyisigxobo esihle somthombo wamandla ojwayelekile, isigxobo esingesihle somthombo wamandla ojwayelekile, ukuphuma kwesigaba sehholo, ukuphuma kwesigaba sehholo le-B kanye nokuphuma kwehholo le-C isigaba. Singasebenzisa izinkomba ezinhlanu zehholo lesilawuli se-brushless (60 ° noma i-120 °) ukuxhuma amandla amahle nokubi weholo ihholo lemoto eyi-brushless, bese sixhuma izinkomba zezinye izinzwa ezintathu zesigaba A, B no-C kuye isibonakaliso sehholo sihola isilawuli ngokuzithandela. Isigaba se-Angle of motor brushless singabonakala ngokushintsha amandla wesilawuli futhi sondle amandla entweni yehholo.

Le ndlela imi kanjena: sebenzisa ibhlokhi engu- + 20V dc ye-multimeter, bese ulinganisa amandla kagesi wemikhondo emithathu ngocingo lokumisa ipeni lemitha elimnyama nepeni lemitha elibomvu ngokulandelana, bese urekhoda ivolumu ephezulu nephansi yemikhondo emithathu . Zungezisa imoto kancane bese uyenza ijikeleze nge-Angle tension Angle encane. Linganisa futhi urekhode umthamo ophakeme nophansi wemikhondo emi-3 futhi, futhi ukwenze izikhathi eziyisithupha. Sisebenzisa u-6 ukumela amandla aphezulu no-1 ukumela amandla aphansi. Ngakho-ke - uma imoto engenamabhulashi ingama-0 ° futhi ijikeleza ngokuqhubekayo ama-engeli wokuphikisana kazibuthe ayisithupha, isinali leqiniso lasehholo elilinganisiwe kufanele libe yi-60, 6, 100, 110, 111, 011. futhi wenze ushintsho lwesiginali seqiniso ngokuhambisana ne-oda elingenhla leqiniso, ukwahlulela isigaba A, B no-C senjini engenamabhulashi nge-001 °.

Uma imoto ye-brushless ingu-120 ° futhi ngokuqhubekayo ijikeleza ama-engeli angama-6 okungezwani komoya, isibonakaliso seqiniso lehholo elilinganisiwe kufanele sishintshe ngokuya ngomthetho we-100, 110, 010, 011, 001, 101, ukuze ukulandelana kwesigaba samanje kwehholo kuholele. kunganqunywa.

Uma ufuna ukunquma ngokushesha ukuthi ngabe imoto eyi-brushless ingu-60 ° noma u-120 °, sebenzisa i-+ 20V dc voltage block ye-multimeter, futhi ulinganise i-voltage yalezi zintathu ngokulandelana ngocingo olungamamitha amnyama nosiba olubomvu. Lapho izintambo ezintathu zinamandla kagesi noma zingenawo ugesi, nquma ukuthi imoto ingu-60 °, uma kungenjalo yi-120 °

Indlela ye-3.Wiring ye-brushless motor. I-Brushless motor ine-3 coil lead ne-5 ehholo eliholayo. Lezi zinkomba eziyi-8 kufanele zihambisane nemikhombandlela ehambisanayo yesilawuli, uma kungenjalo imoto ayikwazi ukujikeleza ngokujwayelekile.

Ngokujwayelekile, imoto engenamabhulashi ene-phase Angle ka-60 ° no-120 ° idinga ukuqhutshwa isilawuli sezimoto ezinamabhulashi anesigaba esihambisanayo Angle sama-60 ° no-120 °. Isilawuli esinama-engeli amabili wesigaba asikwazi ukuguqulwa ngokuqondile. I-motor brushless enama-60 ° isigaba ama-Angle nezintambo ezi-8 ezixhumeke kwisigaba sama-60 ° Isilawuli se-Angle zingaxhunywa ngokufanele ngezindlela ezimbili: enye iya phambili ngokujikeleza, enye ijikeleza ngokubuyela emuva.

Okwezimoto ezingenamabhulashi ezine-phase Angle ka-120 °, ngokulungisa ukulandelana kwesigaba sokuhola kwe-coil nokulandelana kwesigaba sokuhola kwehholo, izinhlobo ezi-6 zokuxhunyaniswa ngokufanele zingenziwa izintambo ezi-8 ezixhunywe yi-motor ne-isilawuli, phakathi kwazo ezi-3 ezixhunyelwe phambili ukuzungeza imoto, kanti enye engu-3 ixhumekile ngokushintshana ngemoto emuva.

Uma imoto ye-brushless ibuyela emuva, okukhombisa ukuthi isigaba se-Angle sesilawuli se-brushless kanye nemidlalo ye-brushless motor, singaguqula ukuqondisa kwemoto ngale ndlela: shintsha i-A no-C yemoto engenamabhulashi nohola eholi wesilawuli se-brushless. ; Ngaleso sikhathi, imigqa ephambili yesigaba A no-B ye-brushless motor ne-brushless controller iyashintshwa.

Amabhayisikili kagesi eza ngezinhlobo ezintathu ezijwayelekile. 1. Dc hub motor, okungukuthi i-brashi motor, imigqa emibili emibili ephumayo, isilawuli se-PWM sangaphandle. I-Ac hub motor ene-sensor yehholo noma engenayo, okuholela ngaphezu kokuthathu, isilawuli sokuguqula imvamisa yangaphandle. 2. Brushless dc wheel hub motor, kufaka phakathi i-commutator kagesi namawaya amabili aphumayo. Isilawuli se-PWM sangaphandle. Qiniseka ukuthi ungadideki.
