Isebenza njani injini?

Phantse isiqingatha samandla asetyenziswa ehlabathini lonke sisetyenziswa ziinjini. Ke ngoko, ukuphuculwa kobuchule beenjini kuthiwa yeyona ndlela isebenzayo yokusombulula iingxaki zamandla ehlabathi.

Uhlobo lwemoto

 

Ngokubanzi, ibhekisa ekuguquleni amandla aveliswa kukuhamba kwangoku kwintsimi yamagnetic ibe yintshukumo ejikelezayo, kwaye ikwabandakanya intshukumo yomgca kuluhlu olubanzi.

 

Ngokohlobo lonikezelo lwamandla oluqhutywa yimoto, lunokwahlulwa lube yi-DC motor kunye ne-AC motor.Ngokomgaqo wokujikeleza kwemoto, inokwahlulwa ngokurhabaxa ibe zezi ntlobo zilandelayo.(ngaphandle kweenjini ezikhethekileyo)

 

Malunga neMijelo, iMagnetic Fields, kunye neMikhosi

 

Okokuqala, ukulungiselela ingcaciso yemigaqo yemoto elandelayo, makhe sihlole imithetho/imithetho esisiseko malunga nemisinga, imagnethi, kunye namandla.Nangona kukho uvakalelo lwe-nostalgia, kulula ukulibala olu lwazi ukuba awuwasebenzisi rhoqo izixhobo zemagneti.

 

Sidibanisa imifanekiso kunye neefomyula ukubonisa.

 
Xa isakhelo esikhokelayo sixande, amandla asebenzayo ngoku athathelwa ingqalelo.

 

Amandla F asebenza kumacala a kunye no-c

 

 

Ivelisa i-torque malunga ne-axis esembindini.

 

Ngokomzekelo, xa uqwalasela imeko apho i-angle yokujikeleza ikhoyo kuphelaθ, amandla asebenza kwii-engile ezichanekileyo ku-b kunye no-d sisonoθ, ngoko ke itorque Ta yecandelo a ibonakaliswa ngale fomula ilandelayo:

 

Ukuqwalasela inxalenye ye-c ngendlela efanayo, i-torque iphindwe kabini kwaye ivelisa i-torque ebalwe ngu:

 

Umfanekiso

Kuba indawo yoxande ingu-S=h·l, ukuyibuyisela kule fomula ingentla ivelisa ezi ziphumo zilandelayo:

 

 

Le fomula ayisebenzi kuphela kooxande, kodwa nakwezinye iimilo eziqhelekileyo njengezangqa.Iimoto zisebenzisa lo mgaqo.

 

Ijikeleza njani imotor?

 

1) Imoto ijikeleza ngoncedo lwemagnethi, amandla omagnetic

 

Ukujikeleza umazibuthe osisigxina kunye neshaft ejikelezayo,① ujikelezisa umazibuthe(ukuvelisa umhlaba ojikelezayo wemagnethi),② ngokomgaqo we-N kunye ne-S izibonda ezikhanga izibonda ezichaseneyo kunye nokugxotha kwinqanaba elifanayo,③ umazibuthe oneshaft ejikelezayo iya kujikeleza.

 

Lo ngumgaqo osisiseko wokujikeleza kwemoto.

 

Umhlaba ojikelezayo wemagnethi (amandla omagnetic) wenziwa ujikeleze ucingo xa umsinga utyhutyha ucingo, kwaye umazibuthe ujikeleza, nto leyo eneneni ikwimeko efanayo yokusebenza.

 

 

Ukongezelela, xa ucingo luhlanjululwe kwi-coil shape, amandla amagnetic adibeneyo, i-magnetic field flux (i-magnetic flux) yenziwe, kwaye i-N pole kunye ne-S pole zenziwe.
Ukongeza, ngokufaka undoqo wentsimbi kucingo olubhijeneyo, kuba lula ukuba amandla omagnetic adlule kuwo, kwaye kunokuveliswa amandla anamandla emagnethi.

 

 

2) Eyona moto ijikelezayo

 

Apha, njengendlela esebenzayo yokujikeleza koomatshini bombane, indlela yokuvelisa umbane ojikelezayo ojikelezayo usebenzisa i-alternating current phase and coils iqaliswa.
(Isigaba esithathu se-AC sisignali ye-AC kunye nekhefu lesigaba se-120 °)

 

  • Umhlaba wokwenziwa kazibuthe kulo ungentla ① imeko ingqamana nalo mfanekiso ulandelayo ①.
  • Umhlaba wokwenziwa kazibuthe kwimeko ② ngasentla ihambelana ② kulo mfanekiso ungezantsi.
  • Umhlaba wokwenziwa kazibuthe kule meko ingasentla ③ ihambelana nalo mfanekiso ulandelayo ③.

 

 

Njengoko kuchazwe ngasentla, inxeba le-coil elijikeleze i-core lihlukaniswe ngezigaba ezintathu, kwaye i-coil ye-U-phase, i-V-phase coil, kunye ne-W-phase coil ihlelwe ngezithuba ze-120 °. Ikhoyili enevoltheji ephezulu ivelisa iN pole, kwaye ikhoyili enombane ophantsi ivelisa i-S pole.
Ekubeni isigaba ngasinye sitshintsha njenge-sine wave, i-polarity (i-N pole, i-S pole) eyenziwa yikhoyili nganye kunye nemagnethi yayo (amandla ombane) iyatshintsha.
Ngeli xesha, jonga nje ikhoyili evelisa i-N pole, kwaye utshintshe ngokulandelelana ngokuhambelana ne-U-phase coil→V-phase coil→W-phase coil→U-phase coil, ngaloo ndlela ujikeleza.

 

Ubume benjini encinci

 

Lo mzobo ungezantsi ubonisa ulwakhiwo jikelele kunye nokuthelekiswa kweenjini ezintathu: i-stepper motor, i-brushed current ngqo (DC) motor, kunye ne-brushless ngqo yangoku (DC) motor.Amacandelo asisiseko kwezi motor ikakhulu ziikhoyili, oomazibuthe kunye neerotors. Ukongeza, ngenxa yeentlobo ezahlukeneyo, zahlulwe zaba luhlobo olusisigxina lwekhoyili kunye nohlobo olusisigxina lwemagnethi.

 

Oku kulandelayo yinkcazo yesakhiwo esihambelana nomzobo womzekelo.Ekubeni kunokubakho ezinye izakhiwo kwisiseko segranular ngakumbi, nceda uqonde ukuba isakhiwo esichazwe kweli nqaku singaphakathi kwesakhelo esikhulu.

 

Apha, i-coil ye-stepper motor igxininiswe ngaphandle, kwaye imagnethi ijikeleza ngaphakathi.

 

Apha, iimagnethi zemoto ye-DC ebrashiweyo zilungiswe ngaphandle, kwaye iikhoyili zijikeleziswa ngaphakathi.Iibhulashi kunye ne-commutator zinoxanduva lokubonelela amandla kwikhoyili kunye nokutshintsha ulwalathiso lwangoku.

 

Apha, i-coil ye-brushless motor igxininiswe ngaphandle, kwaye imagnethi ijikeleza ngaphakathi.

 

Ngenxa yeentlobo ezahlukeneyo zeenjini, nokuba amacandelo asisiseko ayafana, isakhiwo sahlukile.Iinkcukacha ziya kucaciswa ngokweenkcukacha kwicandelo ngalinye.

 

ibhrashi yemoto

 

Ubume bemoto ebrashiweyo

 

Apha ngezantsi yile nto ibrashi yemoto ye-DC ehlala isetyenziswa kwiimodeli ezijongeka ngathi, kunye neskimu esiqhushumbayo sepali ezimbini eziqhelekileyo (imagnethi ezi-2) ezine-slot ezintathu (3 iikhoyili) uhlobo lwemoto.Mhlawumbi abantu abaninzi banamava okuqhaqha injini kunye nokukhupha umazibuthe.

 

Inokubonwa ukuba iimagnethi ezisisigxina zemoto ye-DC ebrashiweyo zilungisiwe, kwaye iikhoyili zemoto ye-DC ebrashiweyo inokujikeleza kumbindi wangaphakathi.Icala elimileyo libizwa ngokuba yi "stator" kwaye icala elijikelezayo libizwa ngokuba yi "rotor".

 

 

Oku kulandelayo ngumzobo weskim wesakhiwo esimele ingqiqo yesakhiwo.

 

 

Kukho abakhweli abathathu (amaphepha esinyithi agobileyo okutshintsha kwangoku) kumda we-axis ejikelezayo ephakathi.Ukuze ugweme ukudibanisa omnye nomnye, abakhweli bahlelwa ngexesha le-120 ° (360 ° ÷3 iziqwenga).Umhambisi uyajikeleza njengoko i-shaft ijikeleza.

 

I-commutator enye idityaniswe nesiphelo sekhoyili enye kunye nesinye isiphelo sekhoyili, kunye nabakhweli abathathu kunye neekhoyili ezintathu zenza yonke (isangqa) njengenethiwekhi yesekethe.

 

Iibrashi ezimbini zigxininiswe kwi-0 ° kunye ne-180 ° ngokuqhagamshelana nomhambisi.Unikezelo lwamandla lweDC lwangaphandle ludityaniswe kwibrashi, kwaye iqukuqela yangoku ngokwendlela yebrashi → isihambisi → ikhoyili → ibrashi.

 

Umgaqo wokujikeleza wemoto ebrashwayo

 

① Jikelezisa ngokunxamnye newotshi ukusuka kwimeko yokuqala

 

Ikhoyili A iphezulu, qhagamshela unikezelo lwamandla kwibrashi, vumela ekhohlo ibe (+) kwaye ekunene ibe (-).Umsinga omkhulu uqukuqela ukusuka kwibhrashi yasekhohlo ukuya ku-A kwikhoyili yesihambisi.Esi sisakhiwo apho inxalenye ephezulu (icala elingaphandle) lekhoyili A iba yi-S pole.

 

Ekubeni i-1/2 yangoku yekhoyili A ihamba isuka kwibhrashi yasekhohlo ukuya kwikhoyili B kunye nekhoyili C kwicala elichaseneyo ukuya kwikhoyili A, amacala angaphandle ekhoyili B kunye nekhoyili C iba zizibonda ezibuthathaka ze-N (ezibonakaliswa ngoonobumba abancinci kancinci umfanekiso).

 

Amandla kazibuthe adalwe kwezi khoyili kunye neziphumo ezinyanyekayo nezinomtsalane zemagnethi zithobela iikhoyili kumandla ajikelezayo achasene newotshi.

 

② Ngaphezu koko, jika unxamnye newotshi

 

Emva koko, kucingelwa ukuba i-brush efanelekileyo idibene nabahambisi ababini kwimeko apho i-coil A ijikelezwe ngokuphambene ne-30 °.

 

I-current coil A iyaqhubeka nokuhamba ukusuka kwibrashi ekhohlo ukuya kwi-brush yasekunene, kwaye ngaphandle kwekhoyili igcina i-S pole.

 

Ikhoyili A efanayo iqukuqela kwiKhoyili B, kwaye umphandle weCoil B uba yeyona N pole inamandla.

 

Ekubeni zombini iziphelo zekhoyili C zifutshane-zijikelezwe ngamabhulashi, akukho ukuhamba kwangoku kwaye akukho mandla ombane avelisiweyo.

 

Nakule meko, amandla okujikeleza okuchasene newotshi anamava.

 

Ukusuka ③ ukuya ④, icoil ephezulu iyaqhubeka ifumana amandla ukuya ngasekhohlo, kwaye icoil esezantsi iyaqhubeka nokufumana amandla ngasekunene, kwaye iyaqhubeka nokujikeleza ngasekunene.

 

Xa ikhoyili ijikeleziswa ukuya ku-③ kunye ④ rhoqo ngama-30 °, xa ikhoyili ibekwe ngaphezu kwe-axis esembindini ethe tye, icala elingaphandle lekhoyili liba yi-S pole; xa ikhoyili ibekwe ngezantsi, iba yi-N pole, kwaye le ntshukumo iyaphindwa.

 

Ngamanye amazwi, i-coil ephezulu iphoqeleka ngokuphindaphindiweyo ngakwesobunxele, kwaye i-coil ephantsi iphoqeleka ngokuphindaphindiweyo ngakwesokudla (zombini kwi-counterclockwise direction).Oku kugcina i-rotor ijikeleza ngasekunene ngalo lonke ixesha.

 

Ukuba udibanisa amandla kwicala lasekhohlo (-) kunye ne-right (+) iibhrashi, iindawo ezichaseneyo zemagneti zenziwe kwiikhoyili, ngoko ke amandla asetyenziswa kwiikhoyili nawo akwicala elichaseneyo, ajika ngasekunene.

 

Ukongezelela, xa amandla ecinyiwe, i-rotor ye-motor brushed iyayeka ukujikeleza ngenxa yokuba akukho ndawo yamagnetic ukuyigcina ijikeleza.

 

Inqanaba lesithathu elipheleleyo-wave brushless motor

 

Imbonakalo kunye nolwakhiwo lwenqanaba lesithathu elipheleleyo-wave motor brushless

 

Umfanekiso ongezantsi ubonisa umzekelo wokubonakala kunye nesakhiwo se-motor brushless.

 

Ngasekhohlo ngumzekelo wenjini yokusonta esetyenziselwa ukujikelezisa idiskhi ye-optical kwisixhobo sokudlala kwakhona kwediski.Iyonke inqanaba lesithathu × i-3 iyonke ye-9 iikhoyili.Ngakwesokudla ngumzekelo we-spindle motor kwisixhobo se-FDD, kunye neekhoyili ze-12 zizonke (isigaba sesithathu × 4).Ikhoyili igxininiswe kwibhodi yesiphaluka kwaye inxeba malunga nentsimbi yentsimbi.

 

I-disk-shaped part ukuya ngasekunene kwekhoyili yi-rotor yemagnethi esisigxina.I-periphery yimagnethi esisigxina, i-shaft ye-rotor ifakwe kwindawo esembindini yekhoyili kwaye igubungela inxalenye yekhoyili, kwaye umazibuthe osisigxina ujikeleze i-periphery yekhoyili.

 

Umzobo wolwakhiwo lwangaphakathi kunye noqhagamshelo lwekhoyili olulinganayo lwesekethe yenqanaba lesithathu elipheleleyo-wave brushless motor

 

Okulandelayo ngumzobo oqingqiweyo wesakhiwo sangaphakathi kunye nomzobo oqingqiweyo wesiphaluka esilinganayo soqhagamshelwano lwekhoyili.

 

Lo mzobo wangaphakathi ngumzekelo we-2-pole elula kakhulu (imagnethi ezi-2) i-3-slot (iikhoyili ezi-3) zemoto.Iyafana nesakhiwo semoto esixutywe nenani elifanayo leepali kunye neendawo zokubeka, kodwa icala lekhoyili lizinzile kwaye imagnethi inokujikeleza.Kakade ke, akukho iibrashi.

Kule meko, i-coil i-Y-ixhunyiwe, isebenzisa i-semiconductor element ukubonelela i-coil ngoku, kwaye i-inflow kunye ne-outflow yangoku ilawulwa ngokwendawo yemagnethi ejikelezayo.Kulo mzekelo, indawo yeHolo isetyenziselwa ukubona indawo yemagnethi.Indawo yeHolo ilungiselelwe phakathi kweekhoyili, kwaye i-voltage eveliswayo ifunyenwe ngokusekelwe kumandla ombane kwaye isetyenziswe njengolwazi lwendawo.Kumfanekiso we-FDD spindle motor enikwe ngaphambili, kunokubonwa ukuba kukho into yeHolo (ngaphezulu kwekhoyili) yokukhangela indawo phakathi kwekhoyili kunye nekhoyili.

 

Izinto zeholo zizaziwa kakuhle zoluvo lwemagnethi.Ubungakanani bommandla wamagnetic bunokuguqulwa bube ngubukhulu be-voltage, kwaye isalathiso semagnethi sinokubonakaliswa njengento enhle okanye embi.Apha ngezantsi kukho umzobo weskim obonisa umphumo weHolo.

 

Izinto zeholo zithatha ithuba lento ethi “xa i-I yangokuI-H iqukuqela kwi-semiconductor kunye ne-magnetic flux B idlula kwii-engile ezichanekileyo ukuya kwixesha langoku, i-voltage V.Hiveliswa kwicala le-perpendicular yangoku kunye nemagnethi", Isazi saseMelika u-Edwin Herbert Hall (u-Edwin Herbert Hall) wafumanisa le nto kwaye wayibiza ngokuba yi "Hall effect".Isiphumo sombane weVHimelwe yile fomula ilandelayo.

VH= (KH/ d) · MnaH・B ※KH: Umlinganiso weholo, d: ubukhulu bomphezulu wokungena wemagnethi

Njengoko ifomyula ibonisa, iphezulu yangoku, iphezulu i-voltage.Olu phawu luhlala lusetyenziselwa ukubona indawo yerotor (umazibuthe).

 

Umgaqo-nkqubo wokujikeleza wesigaba esithathu esipheleleyo-wave motor brushless

 

Umgaqo ojikelezayo wemoto engena brush uya kuchazwa kula manyathelo alandelayo ① ukuya ⑥.Ukuqonda lula, iimagnethi ezisisigxina zenziwe lula ukusuka kwizangqa ukuya kumaxande apha.

 

 

Phakathi kweekhoyili zesigaba sesithathu, kucingelwa ukuba i-coil 1 igxininiswe kwicala le-12 yewotshi, i-coil yesi-2 igxininiswe kwindlela ye-4 yewotshi, kwaye i-coil yesi-3 igxininiswe kwi-clock. ulwalathiso lwentsimbi yesi-8 yewotshi.Vumela i-N pole ye-2-pole yemagnethi esisigxina ibe ngasekhohlo kunye ne-S pole ngasekunene, kwaye inokujikelezwa.

 

I-Io yangoku igeleza kwi-coil 1 ukuvelisa i-S-pole field magnetic ngaphandle kwekhoyili.I-Io / 2 yangoku yenziwa ukuba ihambe ukusuka kwi-Coil 2 kunye ne-Coil 3 ukuvelisa i-N-pole magnetic field ngaphandle kwekhoyili.

 

Xa imimandla yamagnetic yekhoyili yesi-2 kunye ne-3 i-vectorized, i-N-pole magnetic field yenziwa ezantsi, ephindwe ka-0.5 ubukhulu bemagnethi eyenziwe xa i-Io yangoku idlula kwikhoyili enye, kwaye i-1.5 amaxesha amakhulu xa yongezwa. ukuya kumhlaba wemagnethi wekhoyili 1.Oku kudala umphumo wemagnethi kwi-engile ye-90 ° ukuya kwimagnethi esisigxina, ngoko ke i-torque ephezulu inokuveliswa, imagnethi esisigxina ijikeleza ngasekunene.

 

Xa i-current ye-coil 2 iyancipha kwaye i-current ye-coil 3 inyuswa ngokuhambelana nesimo sokujikeleza, i-magnetic field enesiphumo iphinda ijikeleze i-clockwise kwaye i-magnet esisigxina iyaqhubeka nokujikeleza.

 

 

Kwilizwe elijikelezwe ngu-30 °, i-Io yangoku igeleza kwi-coil 1, okwangoku kwi-coil 2 yenziwe zero, kwaye i-Io yangoku iphuma kwi-coil 3.

 

Umphandle wekhoyili 1 uba yi-S pole, kwaye umphandle wekhoyili 3 uba yiN pole.Xa ii-vectors zidityanisiwe, i-magnetic field isiphumo ngu-√3 (≈1.72) amaxesha ombane owenziweyo xa i-Io yangoku idlula kwikhoyili.Oku kwakhona kuvelisa indawo yemagnethi enesiphumo kwi-engile ye-90 ° ukuya kumhlaba wemagnethi osisigxina kwaye ijikeleziswa ngasekunene.

 

Xa i-Inflow yangoku ye-Io ye-coil 1 iyancipha ngokwendawo yokujikeleza, i-current inflow ye-coil 2 inyuswe ukusuka kwi-zero, kwaye i-outflow yangoku ye-coil 3 inyuswe ukuya kwi-Io, i-magnetic field iphinda ijikeleze i-clockwise, kunye nemagnethi esisigxina nayo iyaqhubeka ukujikeleza.

 

※ Kucingelwa ukuba isigaba ngasinye sangoku sisisinusoidal waveform, ixabiso langoku ngu-Io × sin(π⁄3)=Io × √3⁄2 Ngokudityaniswa kwe-vector yendawo yemagnethi, ubukhulu bemagnethi bubonke bufunyanwa njenge ( √ 3⁄2)2× 2 = 1.5 amaxesha.Xa isigaba ngasinye sangoku sisimaza esine, kungakhathaliseki ukuba ithini na indawo yemagnethi esisigxina, ubukhulu bendawo yemagnethi ehlanganisiweyo yi-1.5 yamaxesha ombane owenziwe yicoil, kwaye umhlaba wemagnethi ukwi-angle engama-90 ngokuhlobene. ukuya kumhlaba wemagnethi wemagnethi esisigxina.

 


 

Kwimeko yokuqhubeka nokujikeleza nge-30 °, i-Io / 2 yangoku igeleza kwi-coil 1, i-Io / 2 yangoku igeleza kwi-coil 2, kwaye i-Io yangoku iphuma kwi-coil 3.

 

Umphandle wekhoyili 1 uba yi-S pole, umphandle wekhoyili 2 uphinde ube sisibonda se-S, kwaye umphandle wekhoyili 3 uba yiN pole.Xa ii-vectors zidityanisiwe, i-magnetic field yi-1.5 yamaxesha ombane owenziweyo xa i-Io yangoku ihamba ngekhoyili (efana ne-①).Apha, kwakhona, isiphumo semagnethi senziwa kwi-engile ye-90 ° ngokubhekiselele kumhlaba wemagnethi wemagnethi esisigxina kwaye ijikeleza ngasekunene.

 

④~⑥

 

Jikelezisa ngendlela efanayo ① ukuya ③.

 

Ngale ndlela, ukuba i-current equkuqelayo kwikhoyili itshintsha ngokuqhubekayo ngokulandelelana ngokwendawo yemagnethi esisigxina, imagnethi esisigxina iya kujikeleza ngendlela echanekileyo.Ngokunjalo, ukuba ubuyisela umva ukuhamba kwangoku kwaye ubuyisele umva isiphumo semagnethi, siya kujikeleza ngokuphambeneyo.

 

Lo mzobo ungezantsi ubonisa ngokuqhubekayo umjelo wekhoyili nganye kwinqanaba ngalinye ① ukuya ku-⑥ ngasentla.Ngentshayelelo engentla, kufanele ukuba kwenzeke ukuqonda ubudlelwane phakathi kotshintsho lwangoku kunye nokujikeleza.

 

i-motor ye-stepper

 

I-stepper motor yimoto enokulawula ngokuchanekileyo i-angle yokujikeleza kunye nesantya sokulungelelaniswa nomqondiso we-pulse. I-stepper motor ikwabizwa ngokuba yi "pulse motor".Ngenxa yokuba ii-motor stepper zinokufikelela kwindawo echanekileyo kuphela ngolawulo lwe-loop evulekileyo ngaphandle kokusetyenziswa kwezinzwa zendawo, zisetyenziswa ngokubanzi kwizixhobo ezifuna indawo.

 

Ulwakhiwo lwe-motor stepper (isigaba ezibini se-bipolar)

 

La manani alandelayo ukusuka ekhohlo ukuya ekunene ngumzekelo wenkangeleko yenjini yokunyathela, umzobo weskimu solwakhiwo lwangaphakathi, kunye nomzobo oqingqiweyo wengqiqo yesakhiwo.

 

Kumzekelo wenkangeleko, inkangeleko yohlobo lweHB (Hybrid) kunye nePM (Permanent Magnet) uhlobo lwemoto yokunyathela inikwa.Umzobo wesakhiwo phakathi kwakhona ubonisa isakhiwo sohlobo lwe-HB kunye nohlobo lwe-PM.

 

I-motor steping sisakhiwo apho ikhoyili igxininiswe kwaye imagnethi esisigxina ijikeleza.Umzobo wengqiqo wesakhiwo sangaphakathi se-stepper motor ngakwesokudla ngumzekelo we-PM motor usebenzisa izigaba ezimbini (iisethi ezimbini) zeekhoyili.Kumzekelo wesiseko esisisiseko senjini yokunyathela, iikhoyili zicwangciswe ngaphandle kwaye iimagnethi ezisisigxina zihlelwe ngaphakathi.Ukongeza kwiikhoyili zesigaba ezibini, kukho iindidi ezintathu kunye nezigaba ezintlanu ezinezigaba ezininzi.

 

Ezinye ii-motor stepper zinezinye izakhiwo ezahlukeneyo, kodwa isakhiwo esisisiseko se-stepper motor sinikwe kweli nqaku ukuququzelela ukuqaliswa komgaqo wayo wokusebenza.Ngeli nqaku, ndiyathemba ukuqonda ukuba i-motor yokunyathela ngokusisiseko ithatha ubume bekhoyili esisigxina kunye nemagnethi ejikelezayo ejikelezayo.

 

Umgaqo osisiseko wokusebenza we-stepper motor (uvuselelo lwenqanaba elinye)

 

Lo mzobo ulandelayo usetyenziselwa ukwazisa umgaqo osisiseko wokusebenza we-motor stepper.Lo ngumzekelo we-excitation kwisigaba ngasinye (iseti yeekhoyili) ye-bipolar coil yesigaba ezibini apha ngasentla.Isiseko salo mzobo kukuba imeko iyatshintsha ukusuka ku-① ukuya ku-④.Ikhoyili iqulethe iKhoyili 1 kunye neKhoyili yesi-2, ngokulandelanayo.Ukongeza, iintolo zangoku zibonisa indlela yokuhamba ngoku.
