Sechinhu chedigital execution, stepper motor inoshandiswa zvakanyanya mu motion control system. Vazhinji vashandisi neshamwari mukushandisa stepper motors, vanofunga kuti mota inoshanda nekupisa kukuru, moyo hauna chokwadi, havazivi kana chiitiko ichi chakajairika. Kutaura zvazviri, kupisa chiitiko chinowanzoitika kune stepper motors, asi chiyero chekupisa chinoonekwa sechinowanzoitika, uye nzira yekuderedza kupisa kwe stepper motors?
Kuti tinzwisise kuti sei mota yestepper ichipisa.
Kune mhando dzese dzemamota estepper, mukati mayo mune iron core newinding coil. Kuramba kutenderera, simba rinoburitsa kurasikirwa, kukura kwekurasikirwa uye resistance uye current zvinoenderana nesquare, izvi ndizvo zvatinowanzodaidza kuti copper loss, kana current isiri standard DC kana sine wave, ichaburitsawo harmonic loss; core hysteresis eddy current effect, mu alternating magnetic field ichaburitsawo kurasikirwa, saizi yezvinhu, current, frequency, voltage related, iyo inonzi iron loss. Kurasikirwa kwemhangura uye kurasikirwa kwesimbi zvicharatidzwa muchimiro chekuburitsa kupisa, nokudaro zvichikanganisa kushanda zvakanaka kwemota.
Mota dzinotsika dzinowanzo tevera kurongeka kwenzvimbo uye kubuda kwetorque, kushanda zvakanaka kwakaderera, magetsi anowanzo kuve makuru, uye zvikamu zvine harmonic yakakwira, frequency yemagetsi ichichinjana nekukurumidza uye shanduko, saka mota dzinotsika dzinowanzo kuve nemamiriro ekupisa, uye mamiriro acho akakomba kupfuura mota yeAC.
Uyezve, stepper motor kupisa kudzora mukati memhando yepamusoro.
Kupisa kwemota kunobvumirwa kusvika papi, kunonyanya kuenderana nedanho remukati memota. Kupisa kwemukati hakuparadzwi kusvika pakupisa kwakanyanya (kupfuura madhigirii 130). Saka chero bedzi mukati memota isingapfuure madhigirii 130, mota haizokuvadzwi, uye tembiricha yepamusoro ichave pasi pemadhigirii 90. Saka, tembiricha yepamusoro yemota inokwira ye70-80 degrees yakajairika. Nzira iri nyore yekuyera tembiricha nethermometer, unogona zvakare kutonga zvine hungwaru: neruoko unogona kubata kwemasekondi anopfuura 1-2, kwete kupfuura madhigirii 60; neruoko unogona kubatwa chete, anenge madhigirii 70-80; madonhwe mashoma emvura anopwa nekukurumidza, anopfuura madhigirii 90; zvechokwadi, unogona zvakare kushandisa pfuti yekupisa kuona.
Uyezve, stepper motor inodziya nekuchinja kwekumhanya.
Kana uchishandisa tekinoroji yekufambisa magetsi inoramba iripo, mota yestepper iri kumhanya kwakadzika uye kwakadzika, magetsi acharamba akasimba kuti arambe achiburitsa torque nguva dzose.
Kana kumhanya kwacho kwakwira kusvika pamwero wakati, simba rekudzokera shure mukati memota rinokwira, simba remagetsi rinodzikira zvishoma nezvishoma, uye torque inodzikirawo. Saka, kugadzirwa kwekupisa nekuda kwekurasikirwa nemhangura kune chekuita nekumhanya kwacho.
Kugadzirwa kwekupisa kunowanzo kuve kwakakwira pakumhanya kwakadzika uye kwakadzika uye kwakaderera pakumhanya kwakakwirira. Asi kurasikirwa kwesimbi (kunyangwe chikamu chidiki) kuchinja hakusi iko, uye kupisa kwemota yese ndiko kuunganidzwa kwezvose zviri zviviri, saka zviri pamusoro apa ingori mamiriro ezvinhu akajairika.
Kupisa kunokonzerwa nekupisa
Kupisa kwemota, kunyangwe kazhinji kusingakanganisi hupenyu hwemota, vatengi vazhinji havafanirwe kuiteerera. Zvisinei, kupisa kwakanyanya kunounza mhedzisiro yakaipa.
Zvakadai sezvikamu zvemukati zvemota zvinoderedza kupisa kwemhepo zvine kushushikana kwakasiyana-siyana kunokonzerwa nekuchinja kwemukana wemhepo yemukati uye shanduko diki dzichakanganisa mhinduro yemagetsi yemota, kumhanya kwakanyanya kuchave nyore kurasikirwa nedanho.
Mumwe muenzaniso ndewekuti dzimwe nguva hazvibvumidze kupisa zvakanyanya kwemota, zvakaita semidziyo yekurapa uye michina yekuyedza yakanyatsogadzirwa. Saka, kupisa kwemota kunofanira kudzorwa.
五、 kuderedza kupisa kwemota.
Kuderedza kupisa, ndiko kuderedza kurasikirwa kwemhangura uye kurasikirwa nesimbi. Kuderedza kurasikirwa kwemhangura kune nzira mbiri, kuderedza kuramba uye simba remagetsi, izvo zvinoda kusarudzwa kwesimba remagetsi diki uye simba remagetsi rakaongororwa zvakanyanya sezvinobvira mukusarudza mota diki, mota dzematanho maviri, dzinogona kushandiswa mumota dzakatevedzana hadzifanirwe kuenderana nemota.
Asi izvi zvinowanzopesana nezvinodiwa zve torque uye kumhanya kwakanyanya.
Nekuti mota yakasarudzwa, inofanira kushandisa zvizere basa rekudzora hafu yemagetsi otomatiki uye basa rekunze kwemhepo, yekutanga inoderedza otomatiki magetsi kana mota iri mumamiriro asina kusimba, yekupedzisira inongodzima magetsi.
Pamusoro pezvo, dhiraivha yakakamurwa zvakanaka nekuda kwechimiro chemagetsi chiri pedyo ne sinusoidal, harmonics shoma, kupisa kwemota kuchava kushoma. Hapana nzira dzakawanda dzekuderedza kurasikirwa kwesimbi, huwandu hwemagetsi hunoenderana nemota yedhiraivha ine simba guru, kunyangwe ichizounza hunhu hwekumhanya kwakanyanya, asi zvakare ichaunza kuwedzera kwekupisa.
Saka, tinofanira kusarudza mwero wakakodzera wedhiraivha yedhiraivha, tichifunga nezvekumhanya kwakanyanya, kupfava uye kupisa, ruzha nezvimwe zviratidzo.
