Umqhubi ulawula umbane wesigaba sesithathu se-U / V / W ukwenza intsimi ye-electromagnetic, kwaye i-rotor ijikeleza phantsi kwesenzo sommandla wamagnetic.Kwangelo xesha, i-encoder yemoto ibuyisela umqondiso kwi-drive.Umqhubi uthelekisa ixabiso lengxelo kunye nexabiso elijoliswe kuyo ukulungisa i-angle yokujikeleza kwe-rotor.Ukuchaneka kwe-servo motor kuxhomekeke ekuchanekeni (inani lemigca) ye-encoder.Yahlulwe kwi-DC kunye ne-AC servo motors.Inqaku layo eliphambili kukuba xa i-voltage yesignali i-zero, akukho nto yokujikeleza, kwaye isantya siyancipha ngokulinganayo kunye nokunyuka kwe-torque.Qonda isakhiwo esisisiseko se-servo motor, lawula umgaqo wayo wokusebenza, iimpawu zokusebenza kunye neempawu, kunye nezihlandlo zokusetyenziswa, ukuze ukhethe kwaye uyisebenzise ngokuchanekileyo.Ziziphi iimpawu zomgaqo wokusebenza we-servo motor?
1. Yintoni injini ye-servo?
Iinjini ze-Servo, ezikwabizwa ngokuba zii-actuator motors, zii-actuator kwinkqubo yolawulo eguqula imiqondiso yombane ibe ngama-engile okanye isantya kwi-shaft ukuqhuba into yokulawula.I-Servo motor, ekwabizwa ngokuba yi-emotor yesigqeba, yinto elawulayo kwinkqubo yolawulo oluzenzekelayo eguqula umqondiso ofunyenweyo wombane ube yindawo yokufuduswa kwe-angular okanye i-angular velocity output kwi-motor shaft.
Yahlulwe kwi-DC kunye ne-AC servo motors.Inqaku layo eliphambili kukuba xa i-voltage yesignali i-zero, akukho nto yokujikeleza, kwaye isantya siyancipha ngokulinganayo kunye nokunyuka kwe-torque.
2. Iimpawu eziphezulu ze-servo motor
Xa kukho igalelo lesignali yokulawula, i-servo motor iyajikeleza;ukuba akukho galelo lophawu lolawulo, lizakuyeka ukujikeleza.Isantya kunye nesalathiso se-servo motor sinokutshintshwa ngokutshintsha ubukhulu kunye nesigaba (okanye i-polarity) yolawulo lombane.Ukusukela ngeminyaka yoo-1980, ngophuhliso lweesekethe ezihlanganisiweyo, itekhnoloji ye-elektroniki yamandla kunye netekhnoloji yokulawula isantya se-AC, itekhnoloji yemagnethi esisigxina ye-AC servo drive yenze inkqubela ebonakalayo.Abavelisi beemoto abadumileyo kumazwe ahlukeneyo baphehlelele olwabo uthotho lweemoto ze-AC servo kunye ne-servo drives, kwaye bahlala bephucula kwaye behlaziya.
Inkqubo ye-AC servo iye yaba lelona khokelo lophuhliso lwenkqubo yangoku ye-servo esebenza kakhulu, eyenza ukuba inkqubo ye-servo ye-DC ijongane nengxaki yokupheliswa.Emva kweminyaka yoo-1990s, iinkqubo zorhwebo ze-AC servo kwihlabathi jikelele zaziqhutywa ziimotor ze-sine wave ezilawulwa ngokupheleleyo.Ukuphuhliswa kwe-AC servo drives kwintsimi yokudluliselwa kuyatshintsha ngosuku ngalunye oludlulayo.
3. Xa kuthelekiswa neenjini eziqhelekileyo, ii-motor ze-servo zinezi mpawu zilandelayo
(1) Uluhlu lolawulo lwesantya lubanzi.Njengoko i-voltage yolawulo itshintsha, isantya se-servo motor sinokuhlengahlengiswa ngokuqhubekayo kuluhlu olubanzi.
(2) I-rotor inertia incinci, ngoko inokuqala kwaye imise ngokukhawuleza.
(3) Amandla olawulo mancinci, amandla okulayisha ngaphezulu anamandla, kwaye ukuthembeka kulungile.
4. Ukusetyenziswa okuqhelekileyo kwe-servo motor kwinkqubo yokulawula ngokuzenzekelayo
Siemens, Kollmorgen, Panasonic kunye Yaskawa
Yeyiphi imigaqo yokusebenza yeemoto ze-servo?Ukushwankathela, iisistim ze-AC servo ziphezulu kwiimotor ze-stepper ngeendlela ezininzi.Nangona kunjalo, kwezinye iimeko ezingabalulekanga kangako, iimotor ze-stepper zihlala zisetyenziswa njengeenjini ze-actuator.Ngoko ke, kwinkqubo yoyilo lwenkqubo yokulawula, kuyimfuneko ukuqwalasela ngokubanzi iimfuno zolawulo, iindleko kunye nezinye izinto ukukhetha imotor efanelekileyo yokulawula.
