Umzobo 1: I-Servo motor yinxalenye engundoqo yenkqubo ye-servo.
Ngophuhliso lolwazi, unxibelelwano kunye nobuchwepheshe obuzenzekelayo, iintlobo ezininzi zezixhobo zokulawula ezizenzekelayo zisetyenzisiwe kwimveliso yoshishino kunye nobomi bemihla ngemihla behlabathi lanamhlanje. Njengesinye sezona zixhobo ziqhelekileyo zolawulo oluzenzekelayo, inkqubo ye-servo, eyenziwe yi-servo motor kunye ne-servo drive isetyenziswe ngokubanzi kubomi bethu bemihla ngemihla.
Ngenqaku lethu apha, unokufumana ukuqonda okunzulu apho inokuthi isetyenziswe khona i-servo motor kunye ne-servo drive.
1. Yintoni iServo System?
Inkqubo ye-Servo, yinkqubo yokulawula impendulo esetyenziselwa ukulandela ngokuchanekileyo okanye ukuvelisa inkqubo.
Njengenye yezinto eziphambili zenkqubo ye-servo kunye nenxalenye yokuphunyezwa kwayo, i-servo motor itshintsha indawo yento, i-orientation, i-state kunye nezinye iziphumo ezilawulwayo ubuninzi obulandela igalelo (okanye ixabiso elinikiweyo).
Umsebenzi wayo kukukhulisa, ukuguqula nokulawula amandla ngokweemfuno zomyalelo wolawulo, ukwenzela ukuba i-torque ephumayo, isantya kunye nolawulo lwendawo yesixhobo sokuqhuba luguquguquke kwaye lulungele.
2. Amacandelo eServo System
Inkqubo ikakhulu yenziwe yi-HMI touch screen, i-PLC, i-servo drive, imagnethi esisigxina ye-servo motor. I-servo motor yindlela yokulawula ukuhamba. Iyenza indawo, isantya kunye nolawulo lwangoku, ukuze ihlangabezane neemfuno zokusebenza komsebenzisi.
Umfanekiso 2:Inkqubo ye-Servo yenziwe nge-PLC, i-drive, i-motor, isinciphisi kunye ne-interface.
3. Iimpawu, usetyenziso kunye neentlobo zeServo System
3.1 IIMPAWU ZENKQUBO YE-SERVO
Ifuna isixhobo sokubona esichanekileyo ukuqamba isantya esivaliweyo kunye nelophu yendawo.
IiNgxelo ezahlukeneyo kunye nemigaqo yokuthelekisa
Kukho iintlobo ngeentlobo zemigaqo yokuthelekisa impendulo kunye neendlela. Ngokwemigaqo eyahlukeneyo yesixhobo sokufumanisa ukufezekisa ingxelo yolwazi kunye neendlela ezahlukeneyo zokuthelekisa ingxelo, kukho ukuthelekiswa kwe-pulse, ukuthelekiswa kwesigaba kunye nokuthelekisa i-amplitude ekusebenziseni okuqhelekileyo.
Ukusebenza okuphezulu kweServo Motor
Kwizixhobo zoomatshini be-NC zokulungiswa komphezulu osebenzayo kunye nobunzima, inkqubo ye-servo iya kuhlala ikwinkqubo yokuqalisa rhoqo kunye nokuqhawuka. Ke umyinge wetorque yemoto ukuya kumzuzu we-inertia uyafuneka ukuba ube mkhulu ngokwaneleyo ukuvelisa isantya esikhulu okanye i-braking torque. Kwaye kwakhona i-servo motor iyafuneka ukuba ibe ne-torque enkulu eyaneleyo kwisantya esisezantsi kunye nokusebenza kakuhle, ukuze kuncitshiswe ikhonkco eliphakathi kuqhagamshelo kunye nenxalenye yomatshini ehambayo.
Inkqubo yoLawulo eQheke kakuhle enezantya ezahlukeneyo
Inkqubo enoluhlu olubanzi lolawulo lwesantya, oko kukuthi inkqubo ye-servo yesantya. Ukususela kwisakhiwo solawulo lwenkqubo, indawo yokuvala i-loop yezixhobo zomshini we-CNC inokubonwa njengenkqubo yolawulo oluzenzekelayo oluvaliweyo oluphindwe kabini olunokulungiswa kwendawo kwi-loop yangaphandle kunye nokulungelelaniswa kwesantya kwi-loop yangaphakathi.
Eyona nkqubo yangaphakathi yokusebenza kukuguqula igalelo lesikhundla libe sisiginali yesantya esihambelanayo, emva koko umqondiso uya kuqhuba i-servo motor ukuqaphela eyona ndawo ifudukayo. Intshukumo ephambili yezixhobo zomatshini we-CNC zifuna ukusebenza kokulawulwa kwesantya esiphezulu, ngoko ke inkqubo ye-servo iyadingeka ukuba ibe yinkqubo yolawulo eyenziwe kakuhle enesantya esibanzi.
3.2 UKUSETYENZISWA KWENKQUBO YE-SERVO
Lawula umthwalo wamandla aphezulu kunye nomqondiso womyalelo wamandla aphantsi.
Ilawulwa yi-shaft yokufaka ukufikelela kwi-remote synchronous transmission.
Yenza i-output mechanical displacement ngokuchanekileyo ulandelele umqondiso wombane, njengokurekhoda kunye nokubonisa isixhobo, njl.

5. Iindlela ezizayo zeSicelo seNkqubo yeServo
Inkqubo yokulawula ngokuzenzekelayo ayiphuhli ngokukhawuleza kwithiyori, kodwa iphinda itshintshe ngokukhawuleza kwizixhobo zayo zokusebenza. Kuyo yonke i-3 ~ 5 iminyaka, kukho iimveliso ezintsha kwimarike.
Uphawu lwemoto ye-AC servo yemveli ithambile kwaye imveliso yayo ayiloxabiso elinye.
I-Stepper motor ngokubanzi lulawulo oluvulekileyo lwe-loop kwaye ayikwazi ukuyifumana ngokuchanekileyo. I-motor ngokwayo inommandla we-velocity resonance.
Inkqubo yokulawula isantya se-PWM inomsebenzi ombi wokulandela indawo. Ulawulo lwesantya sokuguqulwa kwamaxesha lulula kodwa ngamanye amaxesha ukuchaneka akwanelanga.
Inkqubo ye-DC motor servo, kunye nokusebenza kwayo okugqwesileyo, isetyenziswe ngokubanzi kwinkqubo ye-servo yendawo. Kodwa izinto ezingeloncedo, ezinje ngolwakhiwo oluntsonkothileyo, ukuchasana okubalulekileyo kwindawo efileyo kwisantya esisezantsi kakhulu, Kwaye ibhrashi ebuyela umva iya kuzisa ingxolo kunye nengxaki yokulungisa.
Imagnethi entsha esisigxina ye-AC servo motor ikhula ngokukhawuleza, ngakumbi xa itshintshile indlela yokulawula ukusuka kwi-square wave ukuya kwi-sine wave. Ukusebenza kwenkqubo kubhetele, kwaye uluhlu lwesantya lwayo lubanzi, lusebenza ngokugqwesileyo kwisantya esicothayo.
