Kodi Servo Drive Imagwira Ntchito Motani?
Mfundo yogwirira ntchito ya servo drive ndi chowongolera chomwe chimagwiritsidwa ntchito kuwongolera servo mota, ndipo ntchito yake ndi yofanana ndi ya frequency converter yomwe imagwira pa mota wamba ya AC.Ndi gawo la servo system ndipo imagwiritsidwa ntchito makamaka pamakina apamwamba kwambiri.
1. Kodi servo drive ndi chiyani komanso momwe imagwirira ntchito?
Kodi mukudziwa momwe servo drive imagwira ntchito?Pakalipano, ma servo amayendetsa onse amagwiritsa ntchito ma processor a digito monga chiwongolero chowongolera, chomwe chimatha kuzindikira zovuta zowongolera zovuta ndikuzindikira ma digito, maukonde ndi luntha.Zida zamagetsi nthawi zambiri zimagwiritsa ntchito mabwalo oyendetsa okhazikika pama module anzeru.Dera loyendetsa galimoto likuphatikizidwa mu IPM ndipo liri ndi maulendo owonetsera zolakwika ndi chitetezo, monga overvoltage, overcurrent, overheating and undervoltage.Dera loyambira lofewa limawonjezedwa ku chipika chachikulu.
Pofuna kuchepetsa chikoka cha njira yoyambira pa dalaivala, gawo loyendetsa magetsi limakonza zolowera magawo atatu kapena mphamvu ya mains kudzera pagawo lagawo lachitatu la mlatho wodzaza mlatho kuti mupezeko komweko.Pambuyo pa magawo atatu a AC kapena kukonzanso mains, chosinthira chamagetsi chamagetsi chapagawo atatu cha sine wave PWM chimagwiritsidwa ntchito kuyendetsa magawo atatu okhazikika maginito synchronous AC servo motor.Njira yonse yagawo loyendetsa mphamvu imatha kunenedwa kuti ndi njira ya AC-DC-AC.
Ndi kugwiritsa ntchito kwakukulu kwa machitidwe a servo, kugwiritsa ntchito ma servo drives, servo drive debugging ndi servo drive kukonza ndizofunikira zonse zaukadaulo zamagalimoto zamagetsi zamafakitale pamagalimoto amasiku ano a servo.

Ma servo drives a AC servo motors amagwiritsidwa ntchito kwambiri
Ma servo drives ndi gawo lofunikira pakuwongolera koyenda kwamakono ndipo amagwiritsidwa ntchito kwambiri pazida zamagetsi, makamaka ma servo drives omwe amagwiritsidwa ntchito kuwongolera ma AC okhazikika maginito synchronous motors akhala malo otentha pano.
