1, maitiro ekudzora kutungamira kwekutenderera kwestepper motor?
Iwe unogona kushandura nhanho nhanho chiratidzo cheiyo control system. Iwe unogona kugadzirisa wiring yemota kuti uchinje mafambiro, sezvinotevera: Kune maviri-chikamu motors, imwe chete yezvikamu zvemota mutsetse wekuchinjana kuwana stepper mota mutyairi anogona kuve, senge A + uye A- kuchinjanisa. Kune matatu-phase motors, kwete imwe yenhanho yekuchinjana mutsara wemota, asi inofanirwa kuve yakatevedzana kuchinjana kwezvikamu zviviri, senge A + uye B + kuchinjanisa, A- uye B- kuchinjanisa.
2, ivostepper motorruzha rwakanyanya kukura, hapana simba, uye mota vibration, kuita sei?
Mamiriro ezvinhu aya anosangana nekuti iyo stepper mota inoshanda munzvimbo ye oscillation, mhinduro.
A, shandura iyo yekuisa chiratidzo frequency CP kudzivirira iyo oscillation zone.
B, kushandiswa kwekugovera dhiraivha, kuitira kuti nhanho yenhanho ideredze, ichimhanya zvakanaka.
3, apostepper motorinobatidzwa, mota shaft haitendeuki kuita sei?
Pane zvikonzero zvinoverengeka nei mota isingatenderere.
A, overload blocking rotation
B, ingave mota yakuvadzwa
C, ingave mota iri kunze kwenyika
D, ingave iyo pulse chiratidzo CP kusvika zero
4, stepper mota yekutyaira simba, mota iri kudedera, haigone kumhanya, kuita sei?
Sangana nemamiriro ezvinhu aya, tanga watarisa kutenderera kwemota uye kubatanidza mutyairi uye hapana kubatana kwakashata, senge pasina kubatana kwakashata, wobva watarisa iyo yekuisa pulse chiratidzo frequency yakakwira zvakanyanya, kunyangwe iyo yekusimudza frequency dhizaini haina musoro.
5, kuita sei basa rakanaka rekusimudza mota yekusimudza curve?
Iko kumhanya kweiyo stepper mota iri kuchinja neinopinza pulse chiratidzo. Nechepfungwa, ingopa mutyairi pulse chiratidzo. Imwe neimwe inopa mutyairi kupomba (CP), mota inotsika inotenderera nhanho yekona (kupatsanurwa kwechikamu chechikamu chedanho). Nekudaro, nekuda kweiyo stepper mota kuita, CP chiratidzo chinoshanduka nekukurumidza, iyo inotsika mota haizokwanise kuenderana nekuchinja kwemagetsi masaini, ayo anoburitsa kuvharira uye kurasika matanho. Saka iyo stepper mota kuti ive yekumhanya kwazvo, panofanirwa kuve nekumhanyisa-up process, pakumira panofanirwa kuve nekumhanya-pasi maitiro. General mhanyisa kukwira nekudzika mutemo mumwechete, unotevera mhanyisa semuenzaniso: mhanyisa maitiro ane kusvetuka frequency pamwe nekumhanyisa curve (uye zvinopesana). Iyo yekutanga frequency haifanirwe kunge yakanyanya kukura, zvikasadaro inoburitsawo kuvhara uye kurasika nhanho. The speed up and down curves are generally exponential curves or adjusted exponential curves, hongu, inogonawo kushandisa mitsetse yakatwasuka kana sine curves, etc. Exponential curve mune chaiyo software programming process inonyanya kunetsa, inowanzoverengerwa in advance nguva maconstindundumi akachengetwa mukombuta ndangariro iyo, maitiro ebasa akasarudzwa zvakananga.
6, stepper mota inopisa, ndeipi yakajairika tembiricha renji?
Kutsika mota tembiricha yakakwira zvakanyanya kunobvisa magineti emota, zvichikonzera kudonha kwe torque uye kunyangwe kurasikirwa kwenhanho. Naizvozvo, iyo yakanyanya kutenderwa tembiricha yemota yekunze inofanirwa kuenderana neiyo demagnetization point yezvinhu zvakasiyana magineti. Kazhinji kutaura, iyo demagnetization point yezvinhu zvemagineti iri pamusoro pe130 degrees Celsius, uye mamwe akatokwira. Saka stepper mota kutaridzika mu80-90 madhigirii Celsius zvakajairika.
7, maviri-chikamu stepper mota uye ina-chikamu stepper mota chii musiyano?
Maviri-phase stepper motors ane maviri chete windings pane stator ine mana anobuda waya, 1.8 ° yedanho rose uye 0.9 ° yehafu nhanho. Mukutyaira, zvinokwana kudzora kuyerera kwezvino uye kutungamira ikozvino kwemaviri-chikamu mhepo. Nepo mana-phase stepper mota mu stator ine ma windings mana, kune sere waya, iyo yese nhanho ndeye 0.9 °, hafu-nhanho ye 0.45 °, asi mutyairi anoda kudzora mana windings, dunhu rinenge rakaoma. Saka maviri-phase mota ine maviri-phase drive, ina-phase sere-waya mota ine parallel, nhevedzano, imwe-danda mhando nzira nhatu dzekubatanidza. Parallel yekubatanidza: ina-chikamu chinomonereka zviviri zviviri, mhepo kuramba uye inductance inodzikira exponentially, mota inomhanya nekuita kwakanaka kwekumhanyisa, kumhanya kwakanyanya ine torque hombe, asi mota inoda kupinza zvakapetwa kaviri yakayerwa ikozvino, kupisa, dhiraivha inobuda simba zvinodiwa zvakawedzera. Kana ichishandiswa munhevedzano, mhepo inopikisa uye inductance inowedzera exponentially, motokari yakagadzikana pamhepo yakaderera, ruzha uye chizvarwa chekupisa idiki, zvinodiwa zvekutyaira hazvina kukwirira, asi kurasikirwa kwepamusoro-kumhanya kwakakura. Saka vashandisi vanogona kusarudza iyo ina-chikamu sere-waya stepper mota wiring nzira zvinoenderana nezvinodiwa.
8, mota ine mana-chikamu mitsara mitanhatu, uye stepper mota mutyairi kureba semhinduro kumitsetse mina, sei kushandisa?
Kune ina-phase matanhatu-waya mota, pombi yepakati yewaya mbiri dzakarembera dzisina kubatana, dzimwe waya ina uye mutyairi zvakabatanidzwa.
9, mutsauko uripo pakati peiyo reactive stepper motors uye hybrid stepper mota?
Yakasiyana muchimiro uye zvinhu, mahybrid motors ane anogara magineti mhando yezvinhu mukati, saka hybrid stepper motors inomhanya zvakati tsvikiti, ine yakakwira inoyangarara simba uye yakaderera ruzha.
