Inkqubo ye-AC servo ye-motor ye-DC engenabhrashi iphuhla ngokukhawuleza ngenxa ye-inertia yayo encinci, i-torque enkulu yokukhupha, ulawulo olulula kunye nempendulo elungileyo ye-dynamic. Inamathuba amaninzi okusetyenziswa. Kwicandelo le-servo drive esebenza kakuhle kunye ne-servo drive echanekileyo, iya kuthatha indawo yenkqubo ye-servo ye-DC yendabuko kancinci kancinci. Nangona kunjalo, i-torque ripple isekhona kwi-BLDC, engenakukwazi ukufikelela kulawulo oluphezulu lwesikhundla kunye nolawulo oluphezulu lwesantya sokusebenza. Ukutshintsha kwe-phase current yenye yezizathu eziphambili ze-torque ripple.

Kwinkqubo ye-AC servo enempendulo yamandla esigaba esingahambiyo, i-torque ejikelezayo ekhawulezayo ingalawulwa, kodwa ayinakulawulwa kwimeko yesantya esiphezulu, i-torque yesigaba esingahambiyo ayinakulawulwa. Ke ngoko, kuyimfuneko ukufumana iskimu sokutshintsha esilungisiweyo ukuze kufezekiswe ukusebenza ngcono kwe-torque ejikelezayo.

Imeko esebenzayo yokutshintsha i-inverter kwinkqubo yokutshintsha kufuneka ikhethwe ngokwemigaqo.

Umthetho 1: Landela indawo yerotor yangoku, oko kukuthi, cima iswitshi ehambelanayo kufuneka inyamalale, kwaye iswitshi ehambelanayo kufuneka imiselwe.

Umthetho 2: phantsi koMthetho 1, ulawulo olulodwa nolwe-bipolar lungasetyenziswa.

Umthetho 3: vumela ukuba ukulibaziseka kweswitshi okufanelekileyo kucinywe.

Iingenelo kunye neempazamo zesicwangciso solawulo lotshintsho phantsi kwemeko yokutshintsha zivavanywa ngezi zikhokelo zimbini zilandelayo:

1. i-torque pulsation ebangelwa kukutshintsha kwamandla incinci kangangoko kunokwenzeka (i-non commutation current pulsation incinci kangangoko kunokwenzeka).

2. nciphisa ixesha lokutshintsha indlela yokusebenza kangangoko kunokwenzeka.

Ngesiqinisekiso se-ETL, CE, ROHS, REACH, ama-60% eemveliso zeWonsmart zithunyelwa eMntla Melika, EU, Japan naseKorea. Abathengi abavela kula mazwe banelisekile kakhulu ngumgangatho ozinzileyo weWonsmart, ukuhanjiswa ngokukhawuleza kunye nexabiso elifanelekileyo.

Siyamkela neeprojekthi ze-ODM kunye ne-OEM kunye neenkcukacha ezenziwe ngokwezifiso.

Siyakuqinisekisa ukuba kufuneka ufake iodolo kuphela, kwaye iya kukhupha iimveliso ezisemgangathweni.

Nceda uzive ukhululekile ukuqhagamshelana nathi.
