I-Servo motor iyinjini elawula ukusebenza kwezingxenye zemishini ohlelweni lwe-servo. Kuyi-axiliary motor indirect transmission device. I-servo motor ingakwazi ukulawula isivinini, ukunemba kwesikhundla kunembile kakhulu, ingaguqula isignali ye-voltage ibe yi-torque kanye nesivinini sokushayela into yokulawula. Isivinini se-Servo motor rotor silawulwa isignali yokufaka, futhi ingaphendula ngokushesha, ohlelweni lokulawula okuzenzakalelayo, njengengxenye yokuphatha, futhi inesikhathi esincane se-electromechanical esingaguquki, umugqa ophezulu, ukuqala kwe-voltage nezinye izici, isignali kagesi etholiwe ingaba iguqulelwe ku-motor shaft e-angular displacement noma ukuphuma kwesivinini se-angular. Ingahlukaniswa ngama-dc servo motors nama-ac servo motors. Izici zayo eziyinhloko ukuthi lapho i-voltage yesignali ingu-zero, akukho mkhuba wokujikeleza, futhi isivinini siyancipha ngokunyuka kwe-torque.

Ama-Servo motors asetshenziswa kakhulu ezinhlelweni ezahlukahlukene zokulawula, ezingaguqula isiginali ye-voltage yokufaka ibe yimishini ephumayo ye-motor shaft futhi ihudule izinto ezilawulwayo ukuze kuzuzwe inhloso yokulawula.

Kukhona ama-dc kanye ne-ac servo motors; I-servo motor yokuqala iyinjini ye-dc ejwayelekile, ekulawuleni ukunemba akuphakeme, ukusetshenziswa kwe-general dc motor ukwenza i-servo motor. I-dc servo motor yamanje iyinjini ye-dc enamandla aphansi esakhiweni, futhi injabulo yayo ilawulwa kakhulu yi-armature nenkundla kazibuthe, kodwa ngokuvamile ukulawula kwezikhali.

Ukuhlukaniswa kwe-motor ejikelezayo, i-dc servo motor ezicini zemishini ingahlangabezana nezidingo zohlelo lokulawula, kodwa ngenxa yokuba khona kwe-commutator, kuneziphambeko eziningi: i-commutator ne-brush phakathi kwezinhlansi ezilula ukukhiqiza, umsebenzi womshayeli wokuphazanyiswa, awukwazi. kusetshenziswe esimweni segesi evuthayo; Kukhona ukungqubuzana phakathi kwebhulashi kanye ne-commutator, okuholela endaweni enkulu efile.

Isakhiwo siyinkimbinkimbi futhi ukugcinwa kunzima.

I-Ac servo motor empeleni iyinjini enezigaba ezimbili engavumelaniyo, futhi kunezindlela ezintathu zokulawula: ukulawula i-amplitude, ukulawulwa kwesigaba nokulawula i-amplitude.

Ngokuvamile, i-servo motor idinga isivinini se-motor ukuthi ilawulwe yisignali ye-voltage; Isivinini sokujikeleza singashintsha ngokuqhubekayo ngokushintsha kwesiginali ye-voltage. Impendulo ye-motor kufanele isheshe, ivolumu kufanele ibe mncane, amandla okulawula kufanele abe mancane. Ama-Servo motors asetshenziswa kakhulu ezinhlelweni ezahlukahlukene zokulawula ukunyakaza, ikakhulukazi uhlelo lwe-servo.
