Inkqubo ye-Brushless DC motor AC servo ikhula ngokukhawuleza ngenxa ye-inertia yayo encinci, i-torque enkulu yemveliso, ulawulo olulula kunye nokuphendula okulungileyo okuguquguqukayo. Inamathuba abanzi okusebenza. Kwintsimi yokusebenza okuphezulu kunye nokuchaneka okuphezulu kwe-servo drive, iya kuthatha indawo kancinane inkqubo ye-servo ye-DC. Nangona kunjalo, i-torque ripple isekhona kwi-BLDC, engakwaziyo ukufikelela ngakumbi kulawulo lwendawo kunye nolawulo lwesantya esiphezulu sokusebenza. Isigaba sokuhamba ngoku sesinye sezizathu eziphambili zetorque ripple.

Kwinkqubo ye-AC servo enempendulo yesigaba esingatshintshiyo ngoku, i-low-speed commutating torque ripple inokulawulwa, kodwa ayikwazi ukulawulwa kwimeko ye-speed-speed, i-non-commutating phase current is uncontrollable. Ke ngoko, kuyafuneka ukufumana iskimu sohlengahlengiso oluphuculweyo ukufezekisa ukusebenza ngcono kwetorque.

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

Umgaqo 1: Landela indawo ye-rotor yangoku, oko kukuthi, cima umtshini ohambelanayo kufuneka unyamalale, kwaye utshintsho oluhambelanayo kufuneka lusekwe.

Umgaqo 2: phantsi koMthetho 1, ulawulo olulodwa kunye ne-bipolar lunokusetyenziswa.

Umthetho wesi-3: vumela ukulibaziseka kokutshintsha okuhambelanayo ukuba kucinywe.

Ukufaneleka kunye neempazamo kwisicwangciso solawulo lokutshintsha phantsi kwemeko yokutshintshwa kuvavanywa ngezi zalathisi zimbini zilandelayo:

I-1.torque pulsation ebangelwa ukutshintshwa kuncinci kunokwenzeka (i-non commutation current pulsation incinci kangangoko kunokwenzeka).

2. ukunciphisa ixesha lokuhamba kangangoko kunokwenzeka.

Nge-ETL, CE, ROHS, REACH Certification, 60% yeemveliso zeWonsmart zithunyelwa ngaphandle kuMntla Melika, EU, Japan naseKorea. Abathengi abasuka kula mazwe baneliseke kakhulu ngumgangatho ozinzileyo weWonsmart, ukuhanjiswa okukhawulezayo kunye nexabiso elifanelekileyo.

Sikwamkele iiprojekthi ze-ODM kunye ne-OEM kunye nokucaciswa okulungiselelweyo.

Siyakuqinisekisa ukuba udinga kuphela ukufaka iodolo, kwaye iya kukhupha iimveliso ezisemgangathweni.

Nceda uzive ukhululekile ukuqhagamshelana nathi.
