Isebenza kanjani i-servo drive:
Njengamanje, amadrayivu e-servo ajwayelekile asebenzisa ama-digital signal processors (DSP) njengomongo wokulawula, angakwazi ukubona ama-algorithms okulawula ayinkimbinkimbi futhi abone ukwenziwa kwedijithali, ukunethiwekha kanye nobuhlakani.Amadivayisi kagesi ngokuvamile asebenzisa isekethe yedrayivu eklanywe nge-intelligent power module (IPM) njengomongo.Qala isifunda ukuze unciphise umthelela kumshayeli ngesikhathi senqubo yokuqalisa.
Iyunithi yedrayivu yamandla iqala ngokulungisa amandla okokufaka ezigaba ezintathu noma amandla amapayipi ngokusebenzisa isifunda sokulungisa ibhuloho eligcwele lezigaba ezintathu ukuze kutholwe amandla e-DC ahambisanayo.Ngemuva kokulungiswa kukagesi wezigaba ezintathu noma ugesi wamapayipi, i-AC servo motor enezigaba ezintathu unomphela uzibuthe iqhutshwa ukuguqulwa kwemvamisa kwe-inverter yohlobo lwe-sinusoidal PWM yezigaba ezintathu.Yonke inqubo yeyunithi yokushayela amandla kungathiwa nje inqubo ye-AC-DC-AC.Isekhethi ye-topological main yeyunithi yokulungiswa (AC-DC) iyisekhethi yokulungisa engalawulwa enezigaba ezintathu egcwele ibhuloho.
Ngokusetshenziswa okukhulu kwezinhlelo ze-servo, ukusetshenziswa kwamadrayivu e-servo, ukulungisa iphutha kwe-servo drive, nokugcinwa kwe-servo drive yizinkinga ezibalulekile zobuchwepheshe zamadrayivu e-servo namuhla.Abahlinzeki besevisi yobuchwepheshe bokulawulwa kwezimboni baya ngokuya benze ucwaningo olunzulu lobuchwepheshe kumadrayivu e-servo.
Amadrayivu e-Servo ayingxenye ebalulekile yokulawula ukunyakaza kwesimanje futhi asetshenziswa kakhulu kumishini ezishintshayo njengamarobhothi ezimboni kanye nezikhungo zemishini ze-CNC.Ikakhulukazi i-servo drive esetshenziselwa ukulawula i-AC unomphela uzibuthe motor synchronous isiphenduke indawo yocwaningo ekhaya naphesheya.Ama-algorithms amanje, isivinini, kanye nesikhundla sesi-3 sokulawula iluphu evaliwe esuselwe kulawulo lwe-vector ngokuvamile asetshenziswa ekwakhiweni kwamadrayivu e-AC servo.Ukuthi idizayini ye-loop evaliwe yesivinini kule-algorithm inengqondo noma ayidlala indima ebalulekile ekusebenzeni kwayo yonke isistimu yokulawula i-servo, ikakhulukazi ukusebenza kokulawula isivinini.
Izidingo zesistimu ye-Servo drive:
1. Ibanga elibanzi lejubane
2. Ukunemba kokuma okuphezulu
3. Ukuqina okwanele kokudlulisela kanye nokuzinza kwejubane eliphezulu.
4. Ukuze kuqinisekiswe ukukhiqiza kanye nekhwalithi yokucubungula,ngaphezu kokudinga ukunemba kokuma okuphezulu, izici ezinhle zokuphendula okusheshayo nazo ziyadingeka, okungukuthi, impendulo kumasiginali womyalo wokulandelela iyadingeka ukuba isheshe, ngoba uhlelo lwe-CNC ludinga ukuhlanganisa nokukhipha lapho uqala futhi ubhuleka.Ukusheshisa kukhulu ngokwanele ukuze kufinyezwe isikhathi senqubo yenguquko yesistimu yokuphakelayo futhi kunciphise iphutha lokushintsha kwekhonto.
5. Isivinini esiphansi kanye ne-torque ephezulu, umthamo oqinile wokulayisha ngokweqile
Ngokuvamile, umshayeli we-servo unamandla okulayisha ngokweqile izikhathi ezingaphezu kuka-1.5 phakathi nemizuzu embalwa noma isigamu sehora, futhi angalayishwa izikhathi ezi-4 kuya kweziyisi-6 ngesikhathi esifushane ngaphandle kokulimala.
6. Ukuthembeka okuphezulu
Kudingeka ukuthi uhlelo lokushayela okuphakelayo lwamathuluzi omshini we-CNC lunokwethenjelwa okuphezulu, ukuzinza okuhle kokusebenza, ukuguquguquka okuqinile kwemvelo kumazinga okushisa, umswakama, ukudlidliza, nekhono eliqinile lokulwa nokuphazamiseka.
Izidingo ze-servo drive yemoto:
1. Injini ingahamba kahle ukusuka ejubaneni eliphansi ukuya kwephezulu, futhi ukushintshashintsha kwetorque kufanele kube kuncane, ikakhulukazi ngesivinini esiphansi esinjengo-0.1r/min noma ngaphansi, kusekhona isivinini esizinzile ngaphandle kokukhasa.
2. I-motor kufanele ibe nomthamo omkhulu wokulayisha ngokweqile isikhathi eside ukuze ihlangabezane nezidingo zejubane eliphansi kanye ne-torque ephezulu.Ngokuvamile, ama-DC servo motors kudingeka ukuthi alayishwe kakhulu izikhathi ezi-4 kuye kweziyi-6 phakathi nemizuzu embalwa ngaphandle kokulimala.
3. Ukuze kuhlangatshezwane nezidingo zokusabela okusheshayo, i-motor kufanele ibe nesikhashana esincane se-inertia kanye ne-torque enkulu ye-stall, futhi ibe nesikhathi esincane esingaguquki kanye ne-voltage yokuqala ngangokunokwenzeka.
4. Injini kufanele ikwazi ukumelana nokuqala, ukubhuleka kanye nokuhlehla ukuphenduka.
