Hunhu hweStepper Motors

01

Kunyangwe kune mota imwe chete yestepper, hunhu hwemoment-frequency hunosiyana zvakanyanya kana uchishandisa zvirongwa zvakasiyana zvekutyaira.

Kana mota yekufambisa iri kushanda, masaini ekurova kwemoyo anowedzerwa kumawinding echikamu chimwe nechimwe nenzira yakatarwa (nenzira yekuti mawindings anowedzerwa simba uye anoderedzwa simba nemugovanisi weringi ari mukati memutyairi).

Mota yeStepping yakasiyana nedzimwe mota, voltage yayo yakayerwa nemazita uye current yakayerwa zvinongova chete mareferensi; uye nekuti mota yestepping inofambiswa nemapulses, voltage yemagetsi ndiyo voltage yayo yepamusoro, kwete voltage yeavhareji, saka mota yestepping inogona kushanda kupfuura huwandu hwayo hwakayerwa. Asi sarudzo haifanirwe kusiyana zvakanyanya nemutengo wakayerwa.

Mota yekutsika haina chikanganiso chakawanda: kazhinji kunyatsoita kwemota yekutsika i3 kusvika ku5 muzana yekona chaiyo yedanho, uye haina kuunganidzwa.

Tembiricha yepamusoro inobvumidzwa yekuonekwa kwemota inokwira: tembiricha yepamusoro yemota inokwira inotanga yabvisa magineti emota, izvo zvinozoita kuti torque iderere kana kutobuda padanho, saka tembiricha yepamusoro inobvumidzwa yekuonekwa kwemota inofanira kutsamira padanho rekubvisa magineti emota dzakasiyana; kazhinji, nzvimbo yekubvisa magineti yemota inokwira kupfuura 130 degrees Celsius, uye dzimwe dzacho dzinosvika kupfuura 200 degrees Celsius, saka, zvakajairika kuti mota inokwira ive netembiricha ye80-90 degrees Celsius pakuonekwa. Saka, tembiricha yekunze kwemota inokwira ndeye 80-90 degrees Celsius zvakajairika.

Torque yemota ichadzikira nekuwedzera kwekumhanya kwekutenderera: kana mota inokwira ichitenderera, inductance yekutenderera kwechikamu chimwe nechimwe chemota ichagadzira simba remagetsi rinodzokera shure; kana frequency yakakwira, simba remagetsi rinodzokera shure rinokura. Pasi pekushanda kwayo, simba remagetsi rinoderera nekuwedzera frequency (kana kumhanya), zvichikonzera kudzikira kwetorque.

Mota inotsika inogona kumhanya zvakajairwa nekumhanya kwakaderera, asi kana yakakwira kupfuura frequency yakati haigone kutanga, uye ichiperekedzwa nekurira kwemuridzo. Mota inotsika ine parameter yehunyanzvi: frequency yekutanga isina mutoro, kureva kuti, mota inotsika mumamiriro ezvinhu asina mutoro inogona kutanga frequency yekurova kwemoyo, kana frequency yekurova kwemoyo yakakwira kupfuura kukosha, mota haigone kutanga zvakajairwa, zvinogona kuitika kurasikirwa nenhanho kana kuvharika. Kana paine mutoro, frequency yekutanga inofanira kunge yakaderera. Kana mota ichizosvika kumhanya kwakakwirira, frequency yekurova kwemoyo inofanira kukurumidziswa, kureva kuti frequency yekutanga inofanira kunge yakaderera, uye yobva yakurumidziswa kusvika kune frequency yaunoda yepamusoro (speed yemota kubva pasi kusvika kumusoro).

Voltage yekugovera yevanotyaira mota dzehybrid stepper inowanzo kuve yakasiyana-siyana, uye voltage yekugovera inowanzo sarudzwa zvichienderana nekumhanya kwemota uye zvinodiwa pakupindura. Kana kumhanya kwemota kuri kwakakwira kana kuti kudiwa kwekupindura kuri kukuru, saka kukosha kwevoltage kwakakwirawo, asi chenjera kuti ripple yevoltage yekugovera haifanirwe kudarika voltage yepamusoro yekupinda yemutyairi, zvikasadaro mutyairi anogona kukuvara.

Simba remagetsi rinowanzo tsanangurwa zvichienderana ne output phase current I yemutyairi. Kana simba remagetsi rakashandiswa, simba remagetsi rinogona kutorwa se1.1 kusvika 1.3 times yeI. Kana simba rekuchinja rikashandiswa, simba remagetsi rinogona kutorwa se1.5 kusvika 2.0 times yeI.

10

Kana chiratidzo chemahara chisina kuvhurwa (offline signal) chiri pasi, simba remagetsi rinobva kumutyairi kuenda kumota rinobviswa uye rotor yemota inenge iri mu free state (offline state). Mune mimwe michina ye automation, kana kutenderera kwakananga kwemota (manual mode) kuchidikanwa pasina drive kupihwa simba, chiratidzo cheFREE chinogona kudzikiswa kuti mota isashande nemaoko kana kugadziriswa. Mushure mekunge kushanda nemaoko kwapera, chiratidzo cheFREE chinodzikiswa zvakare kuti chirambe chichidzora otomatiki.

Nzira iri nyore yekugadzirisa mafambiro ekutenderera kwemota ine maphase maviri mushure mekunge yapihwa simba ndeyekuchinjana A+ neA- (kana B+ neB-) yewaya yemota nemutyairi.
