Ukunyathela kwiiMoto kunye ne-Servo Motor Difference

Tulawula iindlela ezahlukeneyo

I-motor yokunyathela (i-angle ye-pulse, i-open-loop control): isignali ye-pulse yombane iguqulwa ibe yi-angular displacement okanye ukufuduka komgca we-open-loop control, kwimeko yokungagqithisi, isantya semoto, indawo ukumisa kuphela kuxhomekeke kwi-frequency yesiginali ye-pulse kunye nenani lee-pulses, ngaphandle kwempembelelo yokutshintsha komthwalo.

Iimotor zeStepper zihlelwa ikakhulu ngokwenani lezigaba, kwaye iimotor zenqanaba ezibini kunye nenqanaba lesihlanu zisetyenziswa kakhulu kwintengiso. Imotor enamanqanaba amabini anokwahlulwa abe ngamacandelo angama-400 alinganayo kwi-revolution nganye, kwaye inqanaba lesihlanu linokwahlulwa libe ngamacandelo ali-1000 alinganayo, ngoko ke iimpawu zenqanaba lesihlanu lokunyathela motor zingcono, ukukhawulezisa okufutshane kunye nexesha lokuthoba, kwaye zisezantsi. inertia eguqukayo. Inqanaba lenqanaba lemotor ye-hybrid steping motor ngokubanzi yi-3.6 °, 1.8 °, kwaye i-engile yenqanaba le-hybrid steping motor iyi-0.72 °, 0.36 °.

I-Servo motor (i-angle yeepulse ezininzi, ulawulo oluvaliweyo): i-servo motor ikwangolawulo lwenani lee-pulse, i-servo motor rotation angle, iya kuthumela inani elihambelanayo le-pulses, ngelixa umqhubi uya kufumana impendulo. umva umva, kunye ne-servo motor ukwenza uthelekiso lwee-pulses, ukuze inkqubo iya kulazi inani lee-pulses ezithunyelwa kwi-servo motor, kwaye kwangaxeshanye zingaphi iipulse ezifunyenwe ngasemva, ziya kuba nako ukulawula ukujikeleza injini ngokuchanekileyo kakhulu. Ukuchaneka kwemoto ye-servo kugqitywe ngokuchaneka kwe-encoder (inani lemigca), oko kukuthi, i-servo motor ngokwayo inomsebenzi wokuthumela i-pulses, kwaye ithumela inani elihambelanayo lee-pulses kwi-angle nganye. ukujikeleza, ukwenzela ukuba i-servo drive kunye ne-servo motor encoder pulses zenze i-echo, ngoko ke lulawulo oluvaliweyo, kwaye i-motor stepping yi-open-loop control.

Liimpawu ze-ow-frequency zahlukile

Ukunyathela i-motor: i-vibration ye-low-frequency vibration kulula ukwenzeka ngesantya esiphantsi. Xa ukunyathela kwemoto kusebenza ngesantya esiphantsi, ngokubanzi kufuneka kusetyenziswe itekhnoloji yokudambisa ukoyisa into eshukumayo ephantsi, njengokongeza isidambisi kwimoto, okanye ukuqhuba usebenzisa itekhnoloji yokwahlulahlula.

I-Servo motor: ukusebenza okugudileyo kakhulu, nakwizantya ezisezantsi aziyi kubonakala intshukumo yokungcangcazela.

Tiimpawu zakhe mzuzu-frequency ezahlukeneyo

Ukunyathela i-motor: i-torque ye-output iyancipha ngokunyuka kwesantya, kwaye iyancipha ngokukhawuleza kwisantya esiphezulu, ngoko ke isantya sayo esiphezulu sokusebenza sihlala si-300-600r / min.

I-Servo motor: i-torque eqhubekayo ephumayo, oko kukuthi, kwisantya sayo esilinganisiweyo (ngokuqhelekileyo i-2000 okanye i-3000 r / min), i-torque ephumayo inikwe i-torque, kwisantya esilinganiselwe ngaphezu kwemveliso yamandla eqhubekayo.

Dumthamo wokulayisha ngaphezulu

Ukunyathela i-motor: ngokubanzi ayinayo umthamo ogqithisiweyo. Ukunyathela i-motor ngenxa yokuba akukho mandla omthwalo onjalo, ukuze woyise ukhetho lwalo mzuzu we-inertia, kuye kufuneke ukuba ukhethe i-torque enkulu yemoto, kwaye umatshini awufuni i-torque eninzi ngexesha lokusebenza okuqhelekileyo, kuya kubakho. ibe yinkcitho yento yetorque.

Iinjini zeServo: zinomthamo owomeleleyo wokugcwala. Inomthwalo ogqithisiweyo wesantya kunye nesakhono sokulayisha itorque. I-torque yayo ephezulu iphindwe kathathu i-torque elinganisiweyo, engasetyenziselwa ukunqoba umzuzu we-inertial yemithwalo ye-inertial kumzuzu wokuqalisa we-inertia.

Dukusebenza okungafaniyo

Ukunyathela i-motor: ukunyathela ukulawulwa kwemoto kulawulo oluvulekileyo lwe-loop, i-frequency yokuqala iphezulu kakhulu okanye ikhulu kakhulu umthwalo uthambekele ekulahlekelweni ngamanyathelo okanye ukuthintela isenzeko sokumisa isantya esiphezulu kakhulu sithambekele kwinto yokudubuleka, ngoko ke ukuze kuqinisekiswe. ukuchaneka kolawulo lwayo, kufuneka kujongwe nengxaki yokunyuka nokuhla kwesantya.

I-Servo motor: Inkqubo ye-AC servo drive yokulawula i-loop evaliweyo, umqhubi unokuthe ngqo kwisampulu ye-encoder yengxelo ye-encoder, ukwakheka kwangaphakathi kwe-loop yendawo kunye ne-loop yesantya, ngokubanzi ayibonakali ekulahlekeni kwemoto yamanyathelo okanye isenzeko sokugqithisa, ukusebenza kolawulo kunokwethenjelwa ngakumbi.

Sukusebenza impendulo peed yahlukile

Injini yokunyathela: nyusa isantya ukusuka ekumeni ukuya kwisantya sokusebenza (ngokukodwa amakhulu aliqela otshintsho ngomzuzu) ifuna 200 ~ 400ms.

I-Servo motor: I-AC servo inkqubo yokukhawulezisa ukusebenza ingcono, ukusuka ekumiseni isantya ukuya kwisantya esilinganiselweyo se-3000 r / min, kuphela i-millisecond embalwa, ingasetyenziselwa iimfuno zokuqalisa ngokukhawuleza kunye neemfuno zokuchaneka kwendawo yokulawula okuphezulu. intsimi.
