Izici ze-Stepper Motors

01

Ngisho ne-stepper motor efanayo, izici ze- moment-frequency zihluka kakhulu uma usebenzisa izikimu zokushayela ezahlukene.

Lapho isitebhisi semoto sisebenza, amasignali e-pulse ayengezwa kumawindinging esigaba ngasinye ngokulandelana ngendlela ethile (ngendlela yokuthi ama-winding anikwe amandla futhi akhishwe amandla ngumsabalalisi weringi ngaphakathi komshayeli).

I-stepping motor ihlukile kwezinye izinjini, i-voltage yayo elinganiselwe kanye nesilinganiso samanje singamanani okubhekisela kuphela; futhi ngenxa yokuthi injini enyathelayo inikwa amandla ama-pulses, amandla kagesi angamandla kagesi aphezulu kakhulu, hhayi i-voltage ephakathi, ngakho-ke injini yokunyathela ingasebenza ngaphezu kobubanzi bayo obukaliwe. Kodwa okukhethiwe akufanele kuphambuke kakhulu kunani elilinganiselwe.

I-stepping motor ayinalo iphutha eliqoqiwe: ngokuvamile ukunemba kwemoto yokunyathela kungamaphesenti amathathu kuya kwayisihlanu e-engeli yesinyathelo sangempela, futhi ayiqoqiwe.

Izinga lokushisa eliphakeme elivumelekile lokubukeka kwemoto yokunyathela: izinga lokushisa eliphakeme lemoto enyathelayo lizokhipha uzibuthe kuqala izinto zikazibuthe zemoto, okuzoholela ekwehleni kwe-torque noma ukuphuma esinyathelweni, ngakho-ke izinga lokushisa eliphakeme elivumelekile lokubukeka kwemoto kufanele lincike endaweni yokukhipha kazibuthe yezinto zikazibuthe zamamotho ahlukene; ngokuvamile, iphuzu lokususa uzibuthe lezinto kazibuthe lingaphezu kuka-130 degrees Celsius, kanti ezinye zazo zize zifinyelele ngaphezu kuka-200 degrees Celsius, ngakho-ke, kuvamile ngokuphelele ukuthi isitebhisi semoto sibe nezinga lokushisa lama-80-90 degrees Celsius ngokubukeka. Ngakho-ke, izinga lokushisa langaphandle le-steping motor lingama-80-90 degrees Celsius lijwayelekile ngokuphelele.

I-torque ye-motor izokwehla ngokunyuka kwejubane lokujikeleza: lapho i-steping motor ijikeleza, ukungeniswa kwe-inductance yesigaba ngasinye se-motor kuzokwakha amandla e-electromotive reverse; ukuphakama kwefrikhwensi, kuyanda amandla e-electromotive ahlanekezelwe. Ngaphansi kwesenzo saso, isigaba samanje semoto siyancipha ngokukhula kwemvamisa (noma isivinini), okuholela ekwehleni kwetorque.

I-stepping motor ingagijima ngokujwayelekile ngesivinini esiphansi, kodwa uma iphakeme kunemvamisa ethile ayikwazi ukuqala, futhi ihambisana nokushaya ikhwela. I-stepping motor inepharamitha yobuchwepheshe: imvamisa yokuqalisa i-no-load, okungukuthi, i-stepping motor esimweni sokungalayishi ingaqala imvamisa ye-pulse, uma imvamisa ye-pulse iphezulu kunevelu, i-motor ayikwazi ukuqala ngokujwayelekile, kungenzeka ukulahleka kwesinyathelo noma ukuvinjwa. Endabeni yomthwalo, imvamisa yokuqala kufanele ibe ngaphansi. Uma i-motor kufanele ifinyelele isivinini esikhulu, imvamisa ye-pulse kufanele isheshiswe, okungukuthi imvamisa yokuqala kufanele ibe phansi, bese isheshisa imvamisa ephezulu oyifunayo (isivinini se-motor kusuka phansi kuya phezulu).

I-voltage yokuhlinzeka yabashayeli bezimoto eziyi-hybrid stepper ngokuvamile iyibanga elibanzi, futhi i-voltage yokunikezela ivamise ukukhethwa ngokuya ngesivinini sokusebenza kwemoto kanye nezidingo zokuphendula. Uma isivinini sokusebenza semoto siphezulu noma isidingo sokuphendula sishesha, khona-ke inani le-voltage nalo liphezulu, kodwa qaphela ukuthi i-ripple ye-voltage yokuhlinzeka akufanele idlule umthamo omkhulu wokufaka womshayeli, ngaphandle kwalokho umshayeli angase alimale.

Amandla kagesi ngokuvamile anqunywa ngokuya ngesigaba sokukhiphayo samanje somshayeli. Uma kusetshenziswa ugesi olayini, amandla akhona angathathwa njengezikhathi ezingu-1.1 kuya kwezingu-1.3 ze-I. Uma kusetshenziswa ukunikezwa kwamandla okushintshwayo, amandla amanje angathathwa njengezikhathi ezingu-1.5 kuya kwezingu-2.0 ze-I.

Uma isignali engaxhunyiwe ku-inthanethi MAHHALA iphansi, okukhiphayo kwamanje kusuka kumshayeli kuya enjini kuyanqanyulwa futhi i-rotor yemoto isesimweni esikhululekile (isimo sokungaxhunyiwe ku-inthanethi). Kweminye imishini ezishintshayo, uma ukuzungezisa okuqondile kwe-motor shaft (imodi yokwenziwa ngesandla) kudingekile ngaphandle kokuthi idrayivu inikezwe amandla, isignali YAMAHHALA ingasethwa ibe phansi ukuze ikhiphe imoto ku-inthanethi ukuze isebenze mathupha noma ilungiswe. Ngemuva kokuthi ukusebenza mathupha kuqediwe, isignali YAMAHHALA iphinde isethwe phezulu ukuze uqhubeke nokulawula okuzenzakalelayo.

Indlela elula yokulungisa isiqondiso sokuzungezisa kwe-stepper motor enezigaba ezimbili ngemva kokuba inikezwe amandla ukushintshanisa u-A+ no-A- (noma u-B+ no-B-) wezintambo zenjini nomshayeli.
