Hunhu hweStepper Motors

01

Kunyangwe kune imwechete stepper mota, iyo nguva-frequency maitiro anosiyana zvakanyanya kana uchishandisa akasiyana dhiraivha zvirongwa.

2

Kana iyo mota yekutsika iri kushanda, masaini ekupuruzira anowedzerwa kune mahwindi echikamu chimwe nechimwe achichinjana mune imwe kurongeka (nenzira yekuti mamhepo anopihwa simba uye anodzikiswa neanogovera mhete mukati memutyairi).

3

Kutsika mota kwakasiyana nemamwe mamotor, ayo ezita akatemerwa voltage uye yakayerwa ikozvino inongori mareferensi maitiro; uye nekuti mota yekutsika inofambiswa nema pulses, magetsi ekupa magetsi ndiyo yakakwira voltage, kwete avhareji yevoltage, saka mota inotsika inogona kushanda kupfuura iyo yakatemerwa huwandu. Asi sarudzo haifanire kutsauka zvakanyanya kubva kune yakayerwa kukosha.

4

Mota yekutsika haina chikanganiso chaunganidzirwa: kazhinji iko kurongeka kwekutsika mota matatu kusvika mashanu muzana yeiyo chaiyo nhanho kona, uye haina kuunganidzwa.

Yakakura inotenderwa tembiricha yekutsika mota chitarisiko: tembiricha yepamusoro yekutsika mota inotanga demagnetise iyo magineti emota, iyo inotungamira kudonha kwetorque kana kunyange kunze kwenhanho, saka iyo yakanyanya tembiricha inobvumidzwa yekutaridzika kwemota inofanirwa kuenderana neiyo demagnetisation point yeiyo magineti zvinhu zvakasiyana motors; kazhinji, iyo demagnetisation point yeiyo magineti inodarika 130 madhigirii Celsius, uye mamwe acho anotosvika kupfuura 200 madhigirii Celsius, saka, zvakajairika kuti mota inotsika iite tembiricha ye80-90 degrees Celsius muchitarisiko. Naizvozvo, tembiricha yekutsika mota yekunze ndeye 80-90 degrees Celsius yakajairika.

Iyo torque yemota inodzikira nekuwedzera kwekumhanya kwekutenderera: kana mota inotsika ichitenderera, inductance yemhepo yechikamu chimwe nechimwe chemota inoumba reverse electromotive simba; iyo yakakwirira frequency, yakakura reverse electromotive simba. Pasi pechiito chayo, chikamu chemota ikozvino chinodzikira nekuwedzera frequency (kana kumhanya), zvichikonzera kudzikira kwe torque.

Mota yekutsika inogona kumhanya zvakajairika nekumhanya kwakaderera, asi kana yakakwira kupfuura imwe frequency haigone kutanga, uye ichiperekedzwa nekuridza muridzo. Kutsika mota ine tekinoroji parameter: hapana-mutoro wekutanga frequency, ndiko kuti, iyo inotsika mota mune isina-mutoro mamiriro inogona kutanga iyo pulse frequency, kana pulse frequency yakakwira kupfuura kukosha, mota haigone kutanga zvakajairika, inogona kuitika nhanho kurasikirwa kana kuvharika. Muchiitiko chemutoro, nguva yekutanga inofanira kunge yakaderera. Kana iyo mota ichizosvika pakumhanya kwakanyanya, iyo pulse frequency inofanirwa kukurumidza, ie iyo yekutanga frequency inofanira kunge yakaderera, uye yobva yawedzera kune inodiwa yakakwirira frequency (motor kumhanya kubva pasi kusvika kumusoro).

Iyo yekugovera voltage ye hybrid stepper mota madhiraivha anowanzo yakafaranuka, uye magetsi ekupa anowanzo kusarudzwa zvichienderana nekushanda kwemota kumhanya uye mhinduro zvinodiwa. Kana kumhanya kwekushanda kwemota kwakakwira kana chinodiwa chekupindura chiri kukurumidza, saka kukosha kwevoltage kwakakwirawo, asi chenjera kuti ripple yemagetsi ekupa haifanire kudarika iyo yakanyanya kupinza voltage yemutyairi, zvikasadaro mutyairi anogona kukuvara.

9

Iyo magetsi emagetsi ikozvino inotarwa zvichienderana neinobuda chikamu ikozvino I yemutyairi. Kana mutsara wemagetsi unoshandiswa, magetsi ekugadzirisa magetsi anogona kutorwa se 1.1 kusvika 1.3 nguva yeI. Kana kushandiswa kwemagetsi kunoshandiswa, magetsi ekugadzirisa magetsi anogona kutorwa se 1.5 kusvika 2.0 nguva dzeI.

10

Kana iyo yemahara chiratidzo MAHARA yakadzikira, yazvino kubuda kubva kumutyairi kuenda kumota inogurwa uye mota rotor iri munzvimbo yemahara (isina mhepo). Mune mimwe michina yeautomation, kana kutenderera kwakananga kwemota shaft (manual modhi) ichidikanwa pasina dhiraivha ichipihwa simba, iyo YEMAHARA chiratidzo inogona kusetwa yakaderera kuti itore mota kunze kwenyika kuti ishandiswe nemaoko kana kugadzirisa. Mushure mekushanda kwemanyorero kwapera, iyo YEMAHARA chiratidzo inoiswa kumusoro zvakare kuti uenderere mberi neotomatiki kutonga.

11

Nzira iri nyore yekugadzirisa mafambiro ekutenderera kweaviri-phase stepper mota mushure mekunge yasimbiswa ndeyekuchinjanisa iyo A+ neA- (kana B+ neB-) yemota uye mutyairi wiring.
