Iyo yakaderera sei mutengo stepper motors imwe nzira kune servo mota

Yakavharwa-loopstepper motorsvakashandura chiyero chekuita-kune-mutengo mune zvakawanda zvekufambisa zvikumbiro. Kubudirira kweVIC yakavharwa-loop inofambira mberi mota yakavhurawo mukana wekutsiva anodhura servo mota nemutengo wakaderera.stepper motors.Munhamba iri kuwedzera yepamusoro-standard maindasitiri otomatiki applications, tekinoroji kufambira mberi kuri kushandura reshiyo yekuita-kune-mutengo pakati pema stepper motors uye servo motors.
Stepper motors kurwisa servo mota
Zvinoenderana nehuchenjeri hwakajairika, servo control masisitimu anoita zvirinani mumashandisirwo uko kumhanya kunopfuura 800 RPM uye yakakwirira simba mhinduro inodiwa. Stepper motors dzakanyanya kukodzera maapplication ane yakaderera kumhanya, yakaderera kusvika yepakati kukwirisa uye yakakwirira kubata torque.
Saka chii hwaro hwehungwaru hwakajairika nezve stepper motors uye servo mota? Ngationgororei zvakadzama pazasi.

1. Zviri nyore uye mutengo
Stepper motors haisi kungochipa kupfuura servo mota, zvakare zvakareruka kutumwa uye kuchengetedza. Stepper motors dzakagadzikana pakumira uye dzinobata chinzvimbo chadzo (kunyangwe nemitoro ine simba). Nekudaro, kana kuita kwepamusoro kuchidikanwa kune mamwe maapplication, inodhura uye yakaoma servo motors inofanirwa kushandiswa.
2. Chimiro
Stepper motorstenderedza nenzira yenhanho, uchishandisa magineti coils kudhonza zvishoma nezvishoma magineti kubva pane imwe nzvimbo kuenda kune inotevera. Kufambisa mota 100 zvinzvimbo mune chero nzira, dunhu rinoda 100 stepping operations kuti iitwe pamota. Stepper motors dzinoshandisa pulses kuwana mafambiro ekuwedzera, zvichibvumira kunyatsomira pasina kushandisa chero masensa emhinduro.

Iyo servo mota nzira yekufamba yakasiyana. Iyo inobatanidza chinzvimbo sensor - kureva encoder - kune iyo magineti rotor uye inoramba ichiona iyo chaiyo chinzvimbo chemota. Iyo servo inocherekedza mutsauko pakati peiyo chaiyo chinzvimbo chemota uye chinzvimbo chakarairwa uye inogadzirisa ikozvino zvinoenderana. Iyi yakavharwa-loop system inochengeta mota iri mufambo chaiyo.

3. Kukurumidza uye torque
Musiyano mukuita pakati pe stepper uye servo motors unobva kune avo akasiyana mota dhizaini mhinduro.Stepper motorsvane nhamba yakakura kwazvo yemapango pane servomotors, saka kutenderera kwakazara kweanonyandura mota kunoda akawanda akawanda anomonereka azvino kuchinjanisa, zvichikonzera kudonha nekukurumidza mu torque pakuwedzera kumhanya. Uye zvakare, kana iyo yakanyanya torque yakasvikwa, iyo stepper mota inogona kurasikirwa nekumhanya kwayo kusanganisa basa. Nezvikonzero izvi, servo motors ndiyo inosarudzika mhinduro mune akawanda akakwira-kumhanya maapplication. Kusiyana neizvi, iyo yakakwira nhamba yemapango eanotsika mota inobatsira pakumhanya kwakaderera, kana iyo stepper mota ine torque mukana pane servo mota yakaenzana saizi.

Sezvo kumhanya kunowedzera, torque yeiyo stepper mota inoderera

4. Positioning
Pane misiyano yakakosha pakati pe stepper motors uye servo motors mumashandisirwo uko iyo chaiyo chinzvimbo chemuchina inoda kuzivikanwa nguva dzese. Mune yakavhurika-loop mafambiro maapplication anodzorwa nema stepper motors, iyo control system inotora kuti mota inogara iri mune chaiyo mamiriro ekufamba. Zvisinei, mushure mokunge dambudziko rasangana, rakadai semotokari yakavharwa nekuda kwechikamu chakanamatira, mutongi haakwanisi kuziva nzvimbo chaiyo yemuchina, izvo zvinogona kutungamirira pakurasikirwa kwechinzvimbo. Iyo yakavharwa-loop system ye servo mota pachayo ine mukana: kana yakajairwa nechinhu, inozviona nekukurumidza. Muchina unozomira kushanda uye hauzombofi wakabuda panzvimbo.

5. Kupisa uye kushandiswa kwesimba
Open-loop stepper motors anoshandisa yakagadziriswa ikozvino uye anopa kupisa kwakawanda. Yakavharwa-loop control inopa chete ikozvino inodiwa kune yekumhanyisa loop uye nekudaro inodzivirira dambudziko rekudziya kwemota.
Kuenzanisa pfupiso
Servo control masisitimu anonyatsokodzera kune yakakwirira-kumhanya maapplication anosanganisira anochinja emutoro shanduko, senge robhoti maoko. Matanho ekudzora masisitimu, kune rumwe rutivi, anonyanya kukodzera maapplication anoda yakaderera kusvika pakati kumhanyisa uye yakakwirira kubata torque, senge 3D printers, conveyors, sub axes etc. Nekuti stepper motors yakachipa, inogona kuderedza mutengo weotomatiki masisitimu kana ikashandiswa. Motion control masisitimu ayo anoda kutora mukana wehunhu hwe servo motors anozofanira kuratidza kuti aya emhando yepamusoro mota akakodzera huremu hwawo mugoridhe.

Stepper motors ine yakavharwa-loop control
Iyo stepper mota ine yakasanganiswa yemagetsi control yakaenzana neaviri-chikamu brushless DC mota uye inogona kuita chinzvimbo loop control, kumhanya loop control, DQ control, uye mamwe maalgorithms. Iyo single-turn absolute encoder inoshandiswa kuvharika-loop commutation, nekudaro kuve nechokwadi che torque yakakwana chero kumhanya.
Kuderera kwesimba rekushandisa uye kuchengetedza kutonhorera
VIC stepper motors ane simba rakawanda. Kusiyana neyakavhurika-loop stepper motors, iyo inogara ichishanda pane yakazara ikozvino kuraira uye kukonzera kupisa uye ruzha matambudziko, ikozvino shanduko zvinoenderana nemamiriro chaiwo ekufamba, semuenzaniso panguva yekumhanyisa uye kuderera. Zvakafanana ne servos, yazvino inopedzwa neaya ma stepper motors chero nguva yakapihwa inoenderana neiyo torque chaiyo inodiwa. Nekuti iyo mota uye yakasanganiswa yemagetsi control board inomhanya inotonhorera, VIC stepper motors inogona kuwana yakakwira peak torques inofananidzwa neservo motors.

Kunyangwe pakumhanya kwakanyanya, VIC stepper motors inoda zvishoma zvazvino

Inofambiswa nekufambira mberi muakavharika-loop tekinoroji, stepper motors inokwanisa kupinda mukati mekuita kwepamusoro, kumhanyisa maapplication ayo aimbove ari ega servo motors.
Stepper motors ine yakavharwa-loop tekinoroji
Ko kana mabhenefiti eakavharwa-loop servo tekinoroji achigona kuiswa kune stepper motors?
Tinogona here kuzadzisa kuita kwakafanana kune servo motors tichiri kuona mabhenefiti emitengo yema stepper motors?
Nekubatanidza yakavharwa-loop control tekinoroji, iyo stepper mota yaizove yakazara chigadzirwa ine zvakanakira ese ari maviri servo uye stepper motors pamutengo wakaderera. Nekuti yakavharwa-loop stepper motors inopa kuvandudza kwakakosha mukuita uye kushanda nesimba, inogona kutsiva inodhura servo mota muhuwandu huri kuwedzera hwepamusoro-standard application.
Iyi inotevera muenzaniso weVIC yakasanganiswa stepper mota ine yakavharika-loop control kutsanangura mashandiro uye zvakanakira uye zvakaipira zvema stepper motors ane yakavharwa-loop tekinoroji.

Zvakanyatsoenderana nekuita zvinodiwa
Kuti uve nechokwadi che torque yakakwana yekukunda nyonganiso uye kudzivirira nhanho dzakarasika, yakavhurika-loop stepper motors inowanzo fanirwa kuve nechokwadi chekuti torque inosvika makumi mana muzana kupfuura kukosha kunodiwa nekushandisa. Yakavharwa-loop toda stepper motors haina dambudziko iri. Kana aya ma stepper motors akamira nekuda kwekuremerwa, anoenderera mberi akabata mutoro pasina kurasikirwa torque. Vacharamba vachishanda mushure mekunge mamiriro ekuremerwa abviswa. Maximum torque inogona kuvimbiswa pane chero yakapihwa kumhanya uye iyo chinzvimbo sensor inova nechokwadi chekuti hapana kurasikirwa kwenhanho. Yakavharwa-loop stepper motors saka inogona kutsanangurwa kunyatsoenderana ne torque zvinodiwa zvechishandiso chakakodzera pasina kudiwa kweimwe 40% margin.
Iine yakavhurika-loop stepper motors, zvakaoma kuzadzisa yakakwira pakarepo torque zvinodiwa nekuda kwenjodzi yematanho akarasika. Kuenzaniswa neyakajairwa stepper mota, VIC yakavharwa-loop stepper motors inogona kuwana kukurumidza kukurumidza, yakaderera mashandiro eruzha uye yakaderera resonance. Ivo vanogona kushanda pakakwirira bandwidths uye kuwana kuita kwakanakisa.

Hapana cabinet
Toda inosanganisa dhiraivha yekudzora bhodhi nemota, kuderedza huwandu hwewaya uye kurerutsa mhinduro yekushandisa. Ne toda, unogona kuvaka michina isina makabati.

Kubatanidza magetsi ane stepper motors kunoderedza kuoma
Iine yakavharwa-loop tekinoroji, yakavharwa-loop stepper motors inopa vashandisi kunyatsojeka uye kunyatsoita, nekuita kwe servo mota uye mutengo wakaderera weinotsika mota. Yakaderera mutengo stepper motors zvishoma nezvishoma inopinda maapplication ayo angadai akatongwa nemutengo wakakwira servo motors.
