Ukuhlelwa kwemveliso
Imodeli yasekuqaleni ye-stepper motor yaqala ngasekupheleni kweminyaka yoo-1930 ukusuka kwi-1830 ukuya kwi-1860. Ngophuhliso lwezixhobo zemagnethi ezisisigxina kunye neteknoloji ye-semiconductor, i-motor stepper yakhula ngokukhawuleza kwaye yavuthwa.Ngasekupheleni kweminyaka yoo-1960, iTshayina yaqalisa ukuphanda nokwenza iimotor ezizihambelayo.Ukusukela ngoko kude kube sekupheleni kweminyaka yoo-1960, yayilinani elincinci leemveliso eziphuhliswe ziiyunivesithi kunye namaziko ophando ukufunda ezinye izixhobo.Kuphela ekuqaleni kweminyaka yee-1970 kwabakho impumelelo kwimveliso nakuphando.Ukususela phakathi kwiminyaka yama-70 ukuya phakathi kwiminyaka yoo-1980, yangena kwinqanaba lophuhliso, kwaye iimveliso ezahlukeneyo ezikumgangatho ophezulu zaphuhliswa ngokuqhubekayo.Ukusukela phakathi kwiminyaka yee-1980s, ngenxa yophuhliso kunye nophuhliso lweemotor hybrid stepper, itekhnoloji yeemotor ze-hybrid stepper zaseTshayina, kubandakanya itekhnoloji yomzimba kunye netekhnoloji yokuqhuba, ngokuthe ngcembe baye basondela kwinqanaba lamashishini angaphandle.Iimotor ezahlukeneyo ze-hybrid stepper Izicelo zeMveliso zabaqhubi bayo ziyanda.
Njenge-actuator, i-stepper motor yenye yeemveliso eziphambili ze-mechatronics kwaye isetyenziswa ngokubanzi kwizixhobo ezahlukeneyo ezizenzekelayo.Imoto yokunyathela yinto yokulawula i-loop evulekileyo eguqula imiqondiso ye-pulse yombane ibe yi-angular okanye i-linear displacement.Xa umqhubi wokunyathela efumana umqondiso wepulse, uqhuba i-motor yokunyathela ukuba ijikelezise i-angle esisigxina (oko kukuthi, i-angle yokunyathela) kwicala elimiselweyo.Ukufuduka kwe-angular kunokulawulwa ngokulawula inani lee-pulses, ukuze kufezekiswe injongo yokubeka ngokuchanekileyo.I-Hybrid stepper motor yi-stepper motor eyilwe ngokudibanisa izibonelelo zemagnethi esisigxina kunye ne-reactive.Yahlulwe yaba zizigaba ezibini, izigaba ezithathu kunye nezigaba ezihlanu.Inqanaba lenqanaba lenqanaba ezibini liqhelekile kwii-degrees eziyi-1.8.I-angle yenqanaba lenqanaba lesithathu liqhelekileyo li-1.2 degrees.

Ingaba isebenza kanjani
Ubume be-hybrid stepper motor yahlukile kuleyo ye-reactive stepper motor.I-stator kunye ne-rotor ye-hybrid stepper motor zonke zidibeneyo, ngelixa i-stator kunye ne-rotor ye-hybrid stepper motor ihlukaniswe ngamacandelo amabini njengoko kuboniswe kumzobo ongezantsi.Amazinyo amancinci asasazwa kumphezulu.
I-slots ezimbini ze-stator zibekwe kakuhle, kwaye i-windings ihlelwe kubo.Kuboniswe ngasentla ngamanqanaba amabini eenjini eziziinjini ezi-4, i-1, 3, 5, kunye ne-7 zizipali zemagnethi ezijikajikayo, kwaye i-2, 4, 6, ne-8 zizipali zemagnethi ezijikajikayo.Amajiko-jiko epali emagnethi akufuphi kwisigaba ngasinye alinyazwa kumacala achaseneyo ukuvelisa isekethe yemagnethi evaliweyo njengoko kubonisiwe ku-x kunye no-y kumzobo ongasentla.
Imeko yesigaba B ifana nesigaba A. I-slots ezimbini ze-rotor ziphazamiseka ngesiqingatha se-pitch (jonga uMzobo 5.1.5), kwaye umbindi uqhagamshelwe ngentsimbi engapheliyo enomagnetic.Amazinyo amacandelo amabini e-rotor anezibonda ezichasene namagnetic.Ngokomgaqo ofanayo wemoto esebenzayo, okoko nje i-motor inamandla ngokulandelelana kwe-ABABA okanye i-ABABA, i-stepper motor inokuqhubekeka ukujikeleza i-counterclockwise okanye i-clockwise.
Ngokucacileyo, onke amazinyo kwinqanaba elifanayo le-rotor blades ane-polarity efanayo, ngelixa i-polarities yamacandelo amabini e-rotor yamacandelo ahlukeneyo achasene.Owona mahluko mkhulu phakathi kwe-hybrid stepper motor kunye ne-reactive stepper motor kukuba xa imathiriyeli enemagnethi esisigxina ikhutshiwe, kuya kubakho indawo ye-oscillation kunye nendawo yokuphuma.
I-rotor ye-hybrid stepper motor inomagnetic, ngoko ke i-torque eyenziwe phantsi kwe-stator yangoku inkulu kunaleyo ye-motor stepper esebenzayo, kwaye i-angle yayo yesinyathelo ihlala incinci.Ke ngoko, izixhobo zoomatshini boqoqosho be-CNC zihlala zifuna i-hybrid Stepper motor drive.Nangona kunjalo, i-rotor ye-hybrid inesakhiwo esiyinkimbinkimbi kunye ne-inertia enkulu ye-rotor, kwaye isantya sayo singaphantsi kuneso sinyathela esisebenzayo.

Ulwakhiwo kunye nokuqhuba ukuhlela
Baninzi abavelisi basekhaya bee-motor stepper, kwaye imigaqo yabo yokusebenza iyafana.Oku kulandelayo kuthatha inqanaba lasekhaya lesibini le-hybrid stepper motor 42B Y G2 50C kunye nomqhubi wayo SH20403 njengomzekelo ukwazisa ubume kunye nendlela yokuqhuba ye-hybrid stepper motor.[2]
Isigaba ezibini hybrid stepper isakhiwo motor
Kulawulo lwamashishini, isakhiwo esinamazinyo amancinci kwiipali ze-stator kunye nenani elikhulu lamazinyo e-rotor njengoko kuboniswe kuMzobo 1 kungasetyenziswa, kwaye i-angle yayo yesinyathelo ingenziwa encinci kakhulu.Umzobo 1 ezimbini

Umzobo wesakhiwo se-motor ye-hybrid stepping motor, kunye nomzobo we-wiring ye-motor stepping winding kwi-Fig. Umjikelezo westator.Iipali ezinozibuthe ezisi-7 zeze-A-phase winding, kwaye i-2, 4, 6, kunye ne-8 ye-magnetic poles zeze-B-phase winding.Kukho amazinyo ama-5 kumphezulu wepali nganye ye-stator, kwaye kukho i-windings yokulawula kumzimba wepali.I-rotor iqulethe intsimbi emise okwesangqa yamagnetic kunye namacandelo amabini e-iron cores.Intsimbi enozibuthe emile njengesangqa ifakwe kwi-axial direction yerotor.Amacandelo amabini e-iron cores afakwe kwiiphelo ezimbini zensimbi yamagnetic ngokulandelanayo, ukwenzela ukuba i-rotor ihlulwe ibe yizibonda ezimbini zamagnetic kwi-axial direction.Amazinyo angama-50 asasazwa ngokulinganayo kwi-rotor core.Amazinyo amancinci kumacandelo amabini engundoqo agxininiswe ngesiqingatha se-pitch.I-pitch kunye nobubanzi be-rotor esisigxina ziyafana.

Inkqubo yokusebenza yesigaba ezibini se-hybrid stepping motor
Xa amajiko-jiko olawulo ezigaba ezibini ajikelezisa umbane ngokolandelelwano, kuphela isigaba esinye sokuvunguza esinamandla ngokwebhithi nganye, kwaye iibhithi ezine zenza umjikelo.Xa umsinga ugqithiswa kwi-winging yokulawula, amandla e-magnetomotive ayenziwa, asebenzisana namandla emagnetomotive aveliswa yintsimbi esisigxina yamagnetic ukuvelisa i-torque ye-electromagnetic kwaye ibangele ukuba i-rotor yenze intshukumo ye-stepwise.Xa i-A-phase winding inikwe amandla, i-pole ye-S magnetic eveliswa ngokujikeleza kwi-rotor N ngokugqithiseleyo i-pole 1 itsala i-rotor N pole, ukwenzela ukuba i-pole magnetic 1 izinyo-to-izinyo, kwaye imigca yemagnethi iqondiswe. ukusuka kwi-rotor N pole ukuya kumphezulu wezinyo kwi-pole magnetic 1, kunye ne-pole magnetic 5 Izinyo ukuya kwizinyo, izibonda zemagneti 3 kunye ne-7 ziyi-tooth-to-groove, njengoko kubonisiwe kuMfanekiso 4
图 Isigaba se-A-isigaba se-rotor yamandla ye-N egqithisileyo ye-stator ye-stator ye-diagram yokulinganisela.Ngenxa yokuba amazinyo amancinci kumacandelo amabini e-rotor core aphazamisekile ngesiqingatha se-pitch, kwi-S pole ye-rotor, i-S pole magnetic field eveliswa yizibonda zemagneti 1 'kunye ne-5' igxotha i-S pole ye-rotor, leyo kanye izinyo-to-slot kunye rotor, kunye pole 3 'Kwaye 7′tooth umphezulu ivelisa i N-pali kazibuthe, leyo etsala S-pali ye rotor, ukuze amazinyo ubuso amazinyo.I-rotor N-pole kunye ne-S-pole rotor balance diagram xa i-A-phase winding inikwe amandla iboniswe kwi-Figure 3.

Ngenxa yokuba i-rotor inamazinyo angama-50 ewonke, i-angle yayo ye-pitch yi-360 ° / 50 = 7.2 °, kwaye inani lamazinyo ahlala kwi-pole pitch nganye ye-stator ayikho inani elipheleleyo.Ngoko ke, xa isigaba se-A se-stator sinikwe amandla, i-N pole ye-rotor, kunye ne-pali ye-1 Amazinyo amahlanu aphikisana namazinyo e-rotor, kunye namazinyo amahlanu e-pole magnetic 2 yesigaba B esijikelezayo ecaleni. amazinyo e-rotor ane-1/4 ye-pitch misalignment, oko kukuthi, i-1.8 °.Apho isangqa sitsalwa, amazinyo e-A-phase magnetic pole 3 kunye ne-rotor iya kufuduka i-3.6 °, kwaye amazinyo aya kulungelelaniswa kunye ne-grooves.
Umgca wommandla wemagnethi ligophe elivaliweyo ecaleni kwesiphelo sika-N serotha → A (1) S ipali yemagnethi → isangqa esiqhutywa nguzibuthe → A (3 ') Ipali yozibuthe → isiphelo serotha → i-rotor N-isiphelo.Xa isigaba A sivaliwe kwaye isigaba B sinamandla, i-pole ye-magnetic 2 yenza i-N polarity, kunye ne-S pole rotor 7 amazinyo asondeleyo kuyo, ukuze i-rotor ijikeleze i-1.8 ° clockwise ukufikelela kwi-pole magnetic 2 kunye namazinyo e-rotor kumazinyo. , B Ukuphuhliswa kwesigaba samazinyo e-stator of the phase winding kuboniswe kwi-Fig. 5, ngeli xesha, i-pole magnetic 3 kunye namazinyo e-rotor ane-1/4 ye-pitch misalignment.
Ngokufanisa, ukuba amandla aqhubeleka ngokulandelelana kweebhithi ezine, i-rotor ijikeleza inyathelo ngesinyathelo kwicala lewashi.Ngalo lonke ixesha amandla enziwayo, i-pulse nganye ijikeleza nge-1.8 °, oku kuthetha ukuba i-angle yesinyathelo yi-1.8 °, kwaye i-rotor ijikeleza kanye Ifuna i-360 ° / 1.8 ° = i-200 pulses (jonga iMifanekiso 4 kunye ne-5).

Kuyafana nakwisiphelo esigqithiseleyo se-rotor S. Xa amazinyo ajikelezayo aphikisana namazinyo, i-pole magnetic yesinye isigaba ecaleni kwayo iphosakele nge-1.8 °.3 I-Stepper motor driver I-Stepper motor kufuneka ibe nomqhubi kunye nesilawuli ukuze isebenze ngesiqhelo.Indima yomqhubi kukusabalalisa ii-pulses zokulawula kwindandatho kunye nokukhulisa amandla, ukwenzela ukuba i-windings ye-motor stepper inikwe amandla ngendlela ethile yokulawula ukujikeleza kwemoto.Umqhubi we-stepper motor 42BYG250C yi-SH20403.Kwi-10V ～ 40V DC amandla ombane, iitheminali ze-A +, A-, B +, kunye ne-B kufuneka ziqhagamshelwe kwiindlela ezine zenjini yokunyathela.I-DC + kunye ne-DC- iitheminali ziqhagamshelwe kunikezelo lombane lomqhubi we-DC.I-input interface circuit ibandakanya i-terminal eqhelekileyo (dibanisa kwi-terminal echanekileyo yonikezelo lwamandla ombane we-input terminal)., Igalelo lomqondiso wePulse (ukufaka uchungechunge lwee-pulses, ezabelwe ngaphakathi ukuze ziqhube i-stepper motor A, isigaba B), igalelo lesignali yesalathiso (inokuqonda ukujikeleza okulungileyo kunye nokubi kwe-motor stepper), igalelo lesignali engaxhunyiwe kwi-intanethi.
