Incazelo enemininingwane yesimiso sokusebenza, ukuhlukaniswa nezici zama-motor stepper

Yize indlela ejwayelekile yokushayela izimoto emakethe isuselwe kuma-Servo motors asetshenziswa kakhulu, kepha ezimweni 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.Kumelwe kusetshenziswe uhlelo lokulawula olwakhiwe isignali ye-double ring pulse, 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 bekhompyutha, 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 imvamisa ingu-7.5 degrees noma amadigri ayi-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-engeli encane yesinyathelo, 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.
