Iimpawu zeStepper Motors

01

Kwanakwimotor efanayo ye-stepper, iimpawu zomzuzwana-zexesha ziyahluka kakhulu xa usebenzisa izikimu zokuqhuba ezahlukeneyo.

Xa i-motor stepping isebenza, izibonakaliso ze-pulse zongezwa kwii-windings zesigaba ngasinye ngokulandelelana ngendlela ethile (ngendlela yokuba i-windings inikwe amandla kwaye ingabi namandla ngumsasazi weringi ngaphakathi komqhubi).

I-motor yokunyathela yahlukile kwezinye iinjini, i-voltage yayo ye-nominal rated kunye ne-rerated current kuphela ngamaxabiso okubhekisela; kwaye ngenxa yokuba i-motor enyathelayo inikwe amandla ziipulses, amandla ombane ombane ngowona mbane uphezulu, ingeyiyo i-voltage ephakathi, ngoko ke i-motor step inokusebenza ngaphaya koluhlu olulinganisiweyo. Kodwa ukhetho akufanele luphambuke kakhulu kwixabiso elilinganisiweyo.

Imoto yokunyathela ayinayo impazamo eqokelelweyo: ngokubanzi ukuchaneka kwemoto yokunyathela sisithathso ukuya kwisihlanu ekhulwini sokwenyani i-engile, kwaye ayiqokelelwanga.

Ubushushu obuphezulu obuvumelekileyo bokunyathela inkangeleko yemoto: ubushushu obuphezulu bemoto yokunyathela iya kuqala demagnetise imathiriyeli yemagnethi yemoto, eya kukhokelela ekwehleni kwetorque okanye nokuba iphume inyathelo, ngoko ke ubushushu obuphezulu obuvumelekileyo bembonakalo yemoto kufuneka buxhomekeke kwindawo yokukhupha imagnethi yezinto ezizibuthe zeenjini ezahlukeneyo; ngokubanzi, indawo demagnetisation yezinto zemagnethi ingaphezulu kwe-130 degrees celcius, kwaye ezinye zazo zide zifikelele ngaphezu kwama-200 degrees Celsius, ngoko ke, kuyinto eqhelekileyo ukuba i-motor yokunyathela ibe nobushushu obungama-80-90 degrees Celsius ngenkangeleko. Ke ngoko, iqondo lobushushu lemoto yangaphandle yi-80-90 degrees Celsius iqhelekile ngokupheleleyo.

I-torque ye-motor iya kuncipha ngokunyuka kwesantya sokujikeleza: xa i-motor stepping ijikeleza, i-inductance of winding yesigaba ngasinye semoto iya kwenza i-reverse electromotive force; Okukhona iphezulu i-frequency, kokukhona inamandla e-reverse electromotive. Ngaphantsi kwesenzo salo, i-motor phase yangoku iyancipha ngokunyuka kwamaxesha (okanye isantya), okubangela ukuhla kwe-torque.

Imoto yokunyathela inokubaleka ngokwesiqhelo ngesantya esiphantsi, kodwa ukuba iphezulu kune frequency ethile ayinakuqala, kwaye ikhatshwa sisandi somlozi. I-motor yokunyathela ine-parameter yobugcisa: akukho mthwalo wokuqalisa ukuhamba, oko kukuthi, i-motor yokunyathela kwimeko yokungabikho komthwalo inokuqalisa i-pulse frequency, ukuba i-pulse frequency iphezulu kunexabiso, i-motor ayikwazi ukuqalisa ngokuqhelekileyo, ingenzeka ilahleko yenyathelo okanye ukuthintela. Kwimeko yomthwalo, i-frequency yokuqala kufuneka ibe ngaphantsi. Ukuba i-motor ifikelele kwizantya eziphezulu, i-pulse frequency kufuneka ikhawuleziswe, okt i-frequency yokuqala kufuneka ibe phantsi, kwaye emva koko ikhawuleze ukuya kwi-frequency efunwayo ephezulu (isantya semoto ukusuka ezantsi ukuya phezulu).

Amandla ombane obonelelo kubaqhubi beemoto ze-hybrid stepper ngokubanzi luluhlu olubanzi, kwaye amandla ombane ahlala ekhethwa ngokwesantya sokusebenza kwemoto kunye neemfuno zokuphendula. Ukuba isantya sokusebenza semoto siphezulu okanye imfuno yokuphendula ikhawuleza, ke ixabiso le-voltage liphezulu, kodwa qaphela ukuba i-ripple ye-voltage yokubonelela akufanele idlule ubuninzi begalelo lomqhubi, ngaphandle koko umqhubi unokonakala.

Unikezelo lwamandla lwangoku lugqitywe ngokubanzi ngokwesigaba semveliso yangoku yomqhubi. Ukuba unikezelo lwamandla ombane lusetyenzisiwe, umbane wombane ungathathwa njenge-1.1 ukuya kwi-1.3 amaxesha e-I. Ukuba umbane otshintshileyo usetyenziswa, umbane wangoku unokuthathwa njenge-1.5 ukuya kwi-2.0 amaxesha e-I.

Xa isignali engaxhunyiwe kwi-intanethi i-FREE iphantsi, imveliso yangoku esuka kumqhubi ukuya kwi-motor iyanqunyulwa kwaye i-rotor ye-motor ikwi-free state (i-offline state). Kwezinye izixhobo ze-automation, ukuba ukujikeleza ngokuthe ngqo kwe-motor shaft (imowudi ye-manual) iyafuneka ngaphandle kokuba i-drive inikwe amandla, umqondiso we-FREE unokusetwa phantsi ukuze uthabathe i-motor ngaphandle kwe-intanethi ukuze usebenze ngesandla okanye uhlengahlengiso. Emva kokuba umsebenzi owenziwe ngesandla ugqityiwe, uphawu SIMAHLA lusetwa phezulu kwakhona ukuze uqhubeke nolawulo oluzenzekelayo.

Indlela elula yokulungelelanisa indlela yokujikeleza kwemotor yesigaba ezibini emva kokuba inikwe amandla kukutshintsha i-A + kunye ne-A- (okanye i-B + kunye ne-B-) ye-motor kunye ne-wiring yomqhubi.
