Txoj Cai Kev Ua Haujlwm ntawm AC Servo Motors

AC servo motors (feem ntau yog cov hlau nplaum ruaj khov synchronous hom) tsav lub rotor los ntawm kev tsim thiab tswj lub rotating magnetic teb.

 

Tiam sis Rotating Sib Nqus Field: Lub stator yog nruab nrog ob lub windings uas yog sib cais los ntawm 90℃hluav taws xob degrees- lub excitation winding thiab tswj winding. Thaum AC voltages nrog 90℃theem sib txawv yog siv rau ob lub windings no, ib tug rotating magnetic teb yog tsim nyob rau hauv lub cev muaj zog.

 

Rotor Tsav thiab Tswj: Lub rotor ntawm AC servo lub cev muaj zog feem ntau yog cov hlau nplaum ruaj khov (synchronous lub cev muaj zog) lossis ib qho tshwj xeeb tsim squirrel - tawb / hollow khob rotor (asynchronous motor). Lub rotating magnetic teb tsav lub rotor ua raws nws cov kev sib hloov. Los ntawm kev hloov lub amplitude, theem, los yog ob qho tib si (amplitude thiab theem tswj) ntawm kev tswj voltage, qhov kev siv los yog cov yam ntxwv ntawm rotating magnetic teb yuav hloov, yog li precisely tswj lub cev muaj zog ceev thiab kev taw qhia.

 

Cov yam ntxwv thiab kev ua tau zoo: Kom ua tiav cov lus teb sai thiab ntau qhov ceev, lub rotor ntawm AC servo lub cev muaj zog feem ntau muaj kev ua haujlwm siab thiab tsis tshua muaj kev sib hloov inertia. Qhov no tso cai rau nws pib tam sim ntawd thaum tswj hluav taws xob siv thiab nres sai sai thaum tswj qhov hluav taws xob poob (tsis muaj ntug dej hiav txwv), ua rau nws tsim nyog rau cov ntawv thov uas yuav tsum tau pib sai thiab nres thiab qhov chaw meej . ...
