Ngaba uyayazi i-stepper motor

I-Stepper motor licandelo elivulekileyo lokulawula i-loop eliguqula umqondiso we-pulse yombane kwi-angular displacement okanye i-linear displacement.Kwimeko yokungathwali kakhulu, isantya semoto, indawo yokumisa ixhomekeke kuphela kwisantya sophawu lwepulse kunye nenombolo yepulse, kwaye ayichatshazelwa lutshintsho lomthwalo, oko kukuthi, ukongeza umqondiso wepulse kwimotor, imotor iya kujika. i-Angle yenyathelo.Ubukho bobu budlelwane bomgca, zidityaniswa ne-stepper motor kuphela impazamo yexesha kwaye akukho mpazamo yongezelekayo njalo njalo.Yenza kube lula kakhulu ukusebenzisa i-stepper motor ukulawula isantya, indawo kunye nezinye iindawo zolawulo.

Iimpawu ze-1.Stepper motor

< 1 > i-Angle yokujikeleza ilingana ne-pulse yokufaka, ngoko ke iimfuno ze-Angle ephezulu echanekileyo kunye nokubekwa ngokuchanekileyo okuphezulu kunokufezekiswa ngokusebenzisa ulawulo oluvulekileyo lwe-loop.
< 2 > isiqalo esihle, ukuyeka, ukuphendula okulungileyo kunye nokubi, ukulawula okulula.
< 3 > inyathelo ngalinye lemposiso ye-Angle incinci, kwaye akukho mpazamo yokongezelekayo.
<4> ngaphakathi koluhlu olulawulwayo, isantya sokujikeleza silingana nokuphindaphinda kwe-pulse, ngoko ke uluhlu lokudluliselwa lubanzi kakhulu.
< 5 > ekuphumleni, i-motor stepper ine-torque ephezulu yokubamba ukuze ihlale kwindawo yokumisa, ngaphandle kwesidingo sokusebenzisa i-brake ukuze ingajikelezi ngokukhululekile.
< 6 > ine-RPM ephezulu kakhulu.
< 7 > ukuthembeka okuphezulu, akukho kugcinwa, ixabiso eliphantsi lenkqubo yonke.
< 8 > lula ukulahlekelwa inyathelo ngesantya esiphezulu
<9> ivame ukuvelisa i-vibration okanye i-resonance phenomenon kwi-frequency ethile

2.Isigama kwiimotor stepper

* Inombolo yeSigaba: i-logarithm yeekhoyili ezivuselelayo ezivelisa iindawo ezahlukeneyo zemagnethi kwiipali i-N kunye ne-S. M zisetyenziswa ngokuqhelekileyo.
* Inani lamanyathelo: Inani lee-pulses ezifunekayo ukugqibezela utshintsho lwamaxesha athile kwi-magnetic field okanye i-conductive state imelwe yi-N, okanye inani le-pulses elifunekayo ukuze i-motor ijikeleze i-Angle pitch pitch.Thatha inqanaba ezine motor umzekelo, kukho inqanaba ezine-inqanaba lokuphumeza imowudi, ezizezi AB-BC-CD-DA-AB, isigaba sesine-inyathelo lokuphumeza imowudi, ezizezi A-AB-B-BC- C-CD-D-DA-A.
* I-Angle yeNyathelo: ehambelana nesignali ye-pulse, i-angular displacement ye-motor rotor imelwe.= 360 degrees (inani lamazinyo e-rotor J * inani lamanyathelo olawulo).Thatha i-motor yesigaba sesibini kunye nesigaba sesine kunye namazinyo e-rotor njengomzekelo we-50-tooth motor.Ukuphunyezwa kwamanyathelo amane, i-Angle yenyathelo = 360 degrees / (50 * 4) = 1.8 degrees (eyaziwa ngokuba linyathelo lonke), ngelixa ukuphunyezwa kwamanyathelo asibhozo, i-Angle yesinyathelo = 360 degrees / (50 *8)=0.9 degrees (eyaziwa ngokuba sisiqingatha senqanaba).
* I-torque yokumisa: xa i-motor ingenawo amandla, i-torque yokutshixa ye-rotor ye-motor ngokwayo (ebangelwa yi-harmonics ye-meoth shape ye-magnetic field kunye neempazamo zoomatshini).
* I-torque engatshintshiyo: umzuzu wokuvala weshafti yemoto xa i-motor ingajikelezi phantsi kwesenzo sombane esingatshintshiyo.Le torque ngumgangatho wokulinganisa umthamo (ubungakanani bejometri) yemoto kwaye izimeleyo kwi-voltage yokuqhuba kunye nokunikezelwa kwamandla.Nangona i-static torque ilingana nenani le-electromagnetic excitation ampere-turns kwaye inxulumene nomsantsa womoya phakathi kwe-rotor yegiya esisigxina, akucebisi ukunciphisa kakhulu isithuba somoya kunye nokunyusa ukujika kwe-ampere yokuvuselela ukuphucula i-static. i-torque, eya kubangela ukufudumeza kwemoto kunye nesandi soomatshini.
