Umgangatho ophezulu othembekileyo we-86mm stepper

Ngenxa yenkqubela phambili yetekhnoloji, ukudityaniswa kuhlala kwimarike yolawulo lweemoto.Iinjini ze-Brushless DC (i-BLDC) kunye neenjini ezisisigxina zemagnethi ezihambelanayo (PMSM) zobukhulu obahlukeneyo kunye noxinzelelo lwamandla zitshintsha ngokukhawuleza indawo ye-motor topologies efana nebrashi ye-AC/DC kunye ne-AC induction.
Ibrushless DC motor/imagnethi esisigxina motor synchronous inolwakhiwo olufanayo ngoomatshini, ngaphandle kokujija kwestator.I-stator windings yabo ithatha izakhiwo zejometri ezahlukeneyo.I-stator isoloko ichasene nemagnethi yemoto.Ezi motors zinokubonelela ngetorque ephezulu ngesantya esiphantsi, ngoko ke zikulungele kakhulu usetyenziso lweemoto ze-servo.
Iimotor ze-Brushless DC kunye nemagnethi esisigxina ye-synchronous motors ayifuni iibhrashi kunye nee-commutators ukuqhuba iimotor, ngoko ke zisebenza kakuhle kwaye zithembekile kuneemotor ezibrashwayo.
I-Brushless DC motor kunye nemagnethi esisigxina ye-synchronous motor yokulawula ukusetyenziswa kwe-algorithm endaweni yebrashi kunye ne-mechanical commutator ukuqhuba injini ukubaleka.
Ubume bomatshini be-brushless DC motor kunye nemagnethi esisigxina ye-synchronous motor ilula kakhulu.Kukho i-electromagnetic winding kwi-stator engajikeleziyo ye-motor.Yenziwe ngemagnethi esisigxina yerotor.I-stator ingaba ngaphakathi okanye ngaphandle, kwaye ihlala ichasene nemagnethi.Kodwa i-stator isoloko iyingxenye esisigxina, ngelixa i-rotor ihlala iyingxenye ehambayo (ejikelezayo).
Brushless DC motor inokuba 1, 2, 3, 4 okanye 5 izigaba.Amagama abo kunye nee-algorithms zokuqhuba zinokwahluka, kodwa azinabrushless.
Ezinye ii-motor ze-DC ezine-brushless zinezinzwa, ezinokunceda ukufumana indawo ye-rotor.I-algorithm yesoftware isebenzisa ezi zivamvo (i-Sensors zeHolo okanye ii-encoders) ukuncedisa ukuguqulwa kweemoto okanye ukujikeleza kwemoto.Ezi motor brushless DC kunye abenzi boluvo ziyafuneka xa isicelo kufuneka uqalwe phantsi komthwalo ophezulu.
Ukuba i-brushless DC motor ayinayo inzwa yokufumana indawo ye-rotor, imodeli yezibalo iyasetyenziswa.Le mifuziselo yemathematika imele i-algorithms engenazinzwa.Kwi-algorithm engenazinzwa, i-motor yinzwa.
Xa kuthelekiswa ne-brush motor, i-brushless DC motor kunye nemagnethi esisigxina ye-synchronous motor ineenzuzo zenkqubo ebalulekileyo.Banokusebenzisa isikimu sothungelwano lwe-elektroniki ukuqhuba i-motor, enokuphucula ukusebenza kakuhle kwamandla nge-20% ukuya kwi-30%.
Namhlanje, iimveliso ezininzi zifuna isantya semoto esiguquguqukayo.Ezi motors zifuna i-pulse width modulation (PWM) ukutshintsha isantya semoto.Ukumodareyitha kobubanzi bePulse kubonelela ngolawulo oluchanekileyo lwesantya semoto kunye netorque, kwaye inokuqonda isantya esiguquguqukayo.
