DC servo motors txais yuav cov qauv sib tw, nrog rau kev sib hloov inertia tsuas yog 1/3 txog 1/2 ntawm cov DC zoo tib yam, thiab lawv cov cuab yeej siv zog tuaj yeem tiv taus qhov cuam tshuam nrawm. Cov qauv hlau nplaum tas mus li siv cov khoom siv hlau nplaum ruaj khov rau kev ua kom zoo siab, sib txuas cov hlau nplaum siab zog thiab qis hysteresis poob. Cov qauv qis inertia txo qis inertia rotational thiab txhim kho cov lus teb ceev los ntawm optimized rotor tsim. Txhuam yog precisely muab tso rau ntawm lub dav hlau geometric nruab nrab kom paub meej symmetrical rau pem hauv ntej thiab thim rov qab cov yam ntxwv.
Lub hauv paus ntsiab lus: Lub zog rotor tig nyob rau hauv Lorentz quab yuam hauv stator magnetic teb. Tus qauv torque yog:
$$T=K_t \\cdot I$$ qhov twg $K_t$ yog lub torque tas li (tus nqi raug 0.01 ~ 0.1 N·m/A), thiab $I$ yog lub armature tam sim no.
Kaw- txheej txheem tswj lub voj: Tus maub los sib piv lub hom phiaj txoj hauj lwm nrog cov teeb liab tawm tswv yim tiag tiag (xws li cov ntaub ntawv encoder); PWM tsav voltage yog hloov kho los ntawm PID algorithm kom kho lub cev muaj zog thiab kev taw qhia dynamically; Lub sij hawm teb tuaj yeem ua luv luv li 1ms, thiab qhov tseeb qhov chaw ncav cuag ± 0.01℃(cov ntaub ntawv qhov chaw: Yaskawa Electric cov ntaub ntawv).
