Servo motors, dav siv actuators hauv kev tswj tsis siv neeg, ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm txhua hnub vim lawv qhov kev tswj xyuas zoo heev thiab qhov tseeb ntawm qhov chaw. Lawv precisely hloov voltage signals rau torque thiab ceev, zoo tsav tsheb thiab tswj ntau yam khoom. Lub rotor ceev ntawm servo lub cev muaj zog yog tswj hwm los ntawm cov teeb liab tawm tswv yim thiab teb sai heev. Tsis tas li ntawd, lub cev muaj zog no muaj cov yam ntxwv zoo xws li lub sijhawm me me electromechanical tsis tu ncua, siab linearity, thiab qis pib voltage, zoo hloov tau txais hluav taws xob teeb liab mus rau qhov tseeb angular displacement los yog angular tshaj tawm tawm ntawm lub cev muaj zog ncej. Servo motors feem ntau muab faib ua ob pawg: DC thiab AC. Ib tus yam ntxwv zoo tshaj plaws yog tias lawv tsis tig thaum lub teeb liab voltage yog xoom, thiab lawv qhov nrawm nrawm dua li qhov torque nce.
Thaum stepper motors feem ntau muaj lub kaum sab xis ntawm 1.8℃(ob-theem) lossis 0.72℃(tsib-theem), qhov tseeb ntawm AC servo motors nyob ntawm qhov raug ntawm lub tshuab encoder. Siv lub servo lub cev muaj zog ua piv txwv, nws cov encoder yog 16-ntsis. Tus tsav tsheb tau txais 2^16=65,536 pulses ib kiv puag ncig. Cov mem tes sib npaug rau ib lub kiv puag ncig lub cev muaj zog yog 360'/65,536=0.0055. Qhov no ua tiav txoj haujlwm kaw-loop tswj, hauv paus kov yeej lub stepper lub cev muaj zog cov kauj ruam poob teeb meem.
Torque-Frequency Characteristics: Cov zis torque ntawm lub stepper lub cev muaj zog txo nrog kev nce ceev, thiab poob siab ntawm qhov nrawm dua. Nws kev khiav hauj lwm ceev yog feem ntau kaum mus rau pua pua ntawm revolutions ib feeb. Hauv qhov sib piv, AC servo lub cev muaj zog muab qhov tso zis tas li mus txog nws qhov ntsuas ceev (feem ntau 2000 lossis 3000 r / min), thiab lub zog tsis tu ncua ntawm nws qhov ntsuas ceev (E).
Muaj Peev Xwm Tshaj Tawm: Siv Panasonic AC servo lub cev muaj zog ua piv txwv.
Acceleration Performance: Thaum lub cev muaj zog stepper yog unloaded, nws yuav siv sij hawm 200-400ms kom ceev los ntawm ib tug standstill mus rau ob peb puas revolutions ib feeb; AC servo lub cev muaj zog muaj kev ua haujlwm nrawm dua.
