Incazelo enemininingwane yesimiso sokusebenza, ukuhlukaniswa nezici zama-motor stepper

Yize indlela ejwayelekile yokushayela izimoto emakethe isuselwe kuma-Servo motors asetshenziswa kakhulu, kepha ezimeni ezithile, izinzuzo zama-stepper motors zikhulu kakhulu kunalezo zama-servo motors, ngakho-ke kuyadingeka ukuthi onjiniyela be-elekthronikhi baqonde ama-stepper motors, lesi sihloko sizoxoxa ngesimiso sokusebenza, ukuhlukaniswa kanye nezici ze-stepper motors ngokuningiliziwe.

I-Stepper motor iwuhlobo lwe-induction motor. Umgomo wayo wokusebenza ukusebenzisa isekethe ye-elekthronikhi ukuhlela isekethe ye-DC ukuze inikeze amandla ngokwabelana kwesikhathi. Ukulandelana kwezigaba eziningi kulawula okwamanje. Ukusebenzisa lesi samanje ukuhlinzeka amandla ku-stepper motor, i-stepper motor ingasebenza ngokujwayelekile. Ukunikezwa kwamandla okwabelana ngesikhathi kwe-stepper motor.

Nakuba ama-stepper motors asetshenziswe kabanzi, ama-stepper motors awafani nezejwayelekileDC motors, futhiIzinjini ze-ACzisetshenziswa ngokwejwayelekile. Kumele kusetshenziswe uhlelo lokulawula olwakhiwe isignali ye-pulse ephindwe kabili, i-power drive circuit, njll. Ngakho-ke, akulula ukusebenzisa kahle ama-motor stepper. Kubandakanya ulwazi oluningi lobungcweti olufana nemishini, izinjini, izinto zikagesi namakhompyutha.

Njenge-actuator, i-stepper motor ingenye yemikhiqizo esemqoka ye-mechatronics futhi isetshenziswa kakhulu ezinhlelweni zokulawula ezishintshayo.Ngokuthuthuka kobuchwepheshe be-microelectronics kanye nobuchwepheshe bamakhompiyutha, isidingo sama-stepper motors sikhula usuku nosuku, futhi asetshenziswa emikhakheni ehlukahlukene yomnotho wezwe.

Amamotho okunyathela asetshenziswa kakhulu ahlanganisa ama-motor stepping motors (VR), ama-permanent magnet stepping motors (PM), ama-hybrid stepping motors (HB), kanye namamotho okunyathela anesigaba esisodwa.

Unomphela uzibuthe stepper motor:

Imotho yokunyathela unomphela uzibuthe ngokuvamile inezigaba ezimbili, itorque nevolumu kuncane, kanti i-engeli yokunyathela ngokuvamile iba ngamadigri angu-7.5 noma angu-15; umshini wokunyathela unomphela uzibuthe unetorque enkulu ephumayo.Ukusebenza okunamandla kuhle, kodwa i-engeli yesinyathelo inkulu.

Amamotho we-stepper asebenzayo:

I-reactive stepping motor ngokuvamile inezigaba ezintathu, ezingafinyelela umphumela omkhulu we-torque. I-engeli yokunyathela ivamise ukuba ngamadigri angu-1.5, kodwa umsindo nokudlidliza kukhulu kakhulu. I-rotor magnetic routing ye-reactive stepping motor yenziwe ngezinto ezithambile kazibuthe. Kukhona ama-winding field ezigaba eziningi asebenzisa ushintsho ku-permeance ukukhiqiza i-torque.

Injini yokunyathela esebenzayo inesakhiwo esilula, izindleko eziphansi zokukhiqiza, i-angle yesinyathelo esincane, kodwa ukusebenza kabi okuguquguqukayo.

I-Hybrid stepper motor:

I-Hybrid stepping motor ihlanganisa izinzuzo zamamotho wokunyathela asebenza futhi unomphela uzibuthe. Ine-angle yesinyathelo esincane, okukhiphayo okukhulu nokusebenza okuhle okuguquguqukayo. Njengamanje iyinjini yokunyathela esebenza kakhulu. Kubizwa nangokuthi ukungeniswa kwamagnetic unomphela. I-sub-steping motor nayo ihlukaniswe izigaba ezimbili nezigaba ezinhlanu: i-engeli yezigaba ezimbili yokunyathela ingu-1.8 degrees, kanti i-engeli yokunyathela yezigaba ezinhlanu ngokuvamile ingu-0.72 degrees. Lolu hlobo lwenjini yokunyathela lusetshenziswa kakhulu.
