Muaj ob lub ntsiab ntawm servo motors: rotary motors thiab linear motors.
Rotary Servo Tsav
Rotary servo motors yog cov neeg feem coob xav txog thaum lawv xav txog servo motors. Muaj ntau ntau hom servo motors: AC servo motors, stepper servo motors, brushed DC servo motors, ruaj khov hlau nplaum synchronous servo motors, thiab brushless DC servo motors. Cov lus tsa suab ntawm lub servomotor teb feem ntau yog hloov mus rau cov lus tsa suab los ntawm kev siv cov xov (pob screws lossis leadscrews) los yog siv txoj siv sia thiab rub.
Txhua lub cev muaj zog uas muaj lub voj kaw lus tawm tswv yim uas teb rau kev cuam tshuam hauv cov lus tsa suab yog categorized li servomotor.
Feem ntau, lub servo amplifier (los yog tsav tsheb) yog txuas mus rau ib qho chaw ruaj khov hlau nplaum synchronous lub cev muaj zog thiab muab kev tawm tswv yim ntawm kev ceev thiab txoj hauj lwm ntawm tus encoder mounted ntawm lub ncej. Lub amplifier kuj tseem tuaj yeem tau txais cov lus qhia tawm tswv yim los ntawm cov encoders mounted ntawm lwm qhov chaw hauv daim ntawv thov, xws li ntawm cov ntsia hlau los yog tsav rub, kaw lub voj ntawm cov lus tsa suab.
Cov lus qhia tawm tswv yim hloov pauv tus nqi tam sim no lub cev muaj zog tau txais los ntawm lub tshuab hluav taws xob kom ntau qhov tam sim no xa tawm thaum lub cev muaj zog xav tau ntau dua torque thiab tsawg dua tam sim no xa thaum lub cev tsis muaj zog. Nyob rau hauv hom tswj torque, lub servo lub cev muaj zog nce thiab txo qhov voltage kom ceev thiab ib txwm xa cov torque teev.
Linear Servomotors
Linear servomotors yog cov servomotors tiaj tus nyob qhov twg lub rotor nyob rau hauv thiab cov coils nyob rau sab nraud ntawm U-shaped channel tshem tau. Ob qho tib si ntawm cov servo lub cev muaj zog no tau dhau los ua neeg nyiam dua li cov nqi servo lub cev muaj zog txuas ntxiv mus.
