Injini yokunyathelasisixhobo sokulawula i-open-loop motor eguqula imiqondiso ye-pulse yombane ibe yi-angular okanye i-linear displacement, kwaye yeyona nto isebenzayo kwiinkqubo zolawulo lwenkqubo yedijithali yanamhlanje, esetyenziswa ngokubanzi. Inani lee-pulses lingalawulwa ukulawula ukufuduka kwe-angular ukufezekisa indawo echanekileyo; ngelo xesha, i-pulse frequency inokulawulwa ukulawula isantya kunye nokukhawuleza kokujikeleza kwemoto ukufezekisa injongo yokulawula isantya. Ngokubanzi, indlela eqhelekileyo yokufikelela kwindawo echanekileyo yomgca kukudibanisa i-motor stepper kunye ne-sliding screw vice ngodibaniso kunye nesixhobo esikhokelayo, esiguqula intshukumo ejikelezayo ibe yintshukumo yomgca ngokuzibandakanya kwemisonto kunye namantongomane.
I-motor stepper motor isebenzisa itekhnoloji ekhethekileyo yokudibanisa i-screw sub kunye ne-stepper motor kwiyunithi enye, ukuze abathengi bangadingeki bafakele i-couplings xa beyisebenzisa, engagcini nje ngokugcina indawo yokufakela, kodwa inokuphucula ngokufanelekileyo ukusebenza kwenkqubo yokuhlanganisa. Iimotor ze-linear stepper zinokwahlulwa zibe ziindidi ezine ngokwesakhiwo: uhlobo lwe-drive yangaphandle, uhlobo olungabanjwanga, uhlobo lwe-shaft esisigxina kunye ne-slider linear motor.
Eli nqaku lazisa umgaqo-siseko we-Non-captiveiinjini ze-stepper ezinemigcakwaye ekugqibeleni ichaza izibonelelo zayo zesicelo.
Umgaqo we-Non-captive linear stepper motor
Ongabanjwangaumgca stepper motoridibanisa i-nut kunye ne-motor rotor kwiyunithi enye, kunye ne-screw shaft edlula embindini we-motor rotor. Ekusetyenzisweni, intonga ye-filament igxininiswe kwaye yenziwe i-anti-rotation, kwaye xa i-motor inikwe amandla kwaye i-rotor ijikeleza, i-motor iya kwenza i-linear motion kunye ne-filament rod. Ngakolunye uhlangothi, ukuba i-motor ilungisiwe kwaye intonga ye-filament yenza i-anti-rotation ngaxeshanye, ngoko intonga ye-filament iya kwenza intshukumo yomgca.
Iingenelo zosetyenziso lweemotor ze-Non-captive linear stepper
Ngokuchasene neemeko zesicelo apho iimotor ze-stepper stepper eziqhutywa ngaphandle zisetyenziswa kunye nezikhokelo zomgca, ii-motor non-captive linear stepper motors zineenzuzo zazo ezizodwa, ezibonakaliswe kwiindawo ezi-3 ezilandelayo.
Ivumela impazamo enkulu yofako lwesixokelelwano.
Ngokuqhelekileyo, ukuba i-motor ye-stepper eqhutywa ngaphandle isetyenzisiweyo, kukho umngcipheko omkhulu wokumisa inkqubo ukuba i-filament kunye ne-guideway ayixhonywanga ngokufanayo. Nangona kunjalo, ngeenjini ze-non-captive linear stepper motors, le ngxaki ebulalayo inokuphuculwa kakhulu ngenxa yeempawu zesakhiwo soyilo lwazo, ezivumela impazamo enkulu yenkqubo.
Ukuzimela kwisantya esibalulekileyo sentonga yefilament.
Xa i-motor ye-stepper eqhutywa ngaphandle ikhethwa kwi-high-speed linear motion, idla ngokukhawulelwa ngesantya esibalulekileyo sentonga ye-filament. Nangona kunjalo, nge-Non-captive linear stepper motor, i-filament bar igxininiswe kwaye yenziwe i-anti-rotational, ivumela i-motor ukuba iqhube isilayidi sesikhokelo somgca. Ekubeni i-screw imile, ayikhawulelwanga ngesantya esibalulekileyo se-screw xa ufikelela kwisantya esiphezulu.
Ufakelo lokugcina indawo.
Injini ye-stepper engabanjwanga, ngenxa ye-nut eyakhelwe-ngaphakathi kuyilo lwesakhiwo semoto, ayizukuthatha indawo eyongezelelweyo ngaphaya kobude be-screw. Iinjini ezininzi zinokufakwa kwi-screw efanayo, kwaye ii-motor azikwazi "ukudlula" enye kwenye, kodwa ukunyakaza kwazo kuzimele omnye komnye. Ke ngoko, lolona khetho lulungileyo lwezicelo apho iimfuno zendawo zingqongqo.
