1. Ayizizo Zonke Iintshukumo Ezidalwa Ngokulinganayo: Umahluko Ophambili Phakathi Kwee-LRA NeeMoto Zemveli

Xa sicinga "ngokungcangcazela," uninzi lwethu lucinga ngeemoto zerotor ezikhalayo kwiifowuni ezindala—ezifana neemoto kwiimoto zokudlala zabantwana, ezivelisa ukungcangcazela ngokujikelezisa irotor engaqhelekanga. Kodwa le ndlela yokungcangcazela "engacacanga" ayisakwazi ukuhlangabezana neemfuno eziphezulu zezixhobo zanamhlanje zamava okuchukumisa: impendulo ecothayo, impendulo ecothayo, kwanengxolo engafunekiyo evela kumzimba wesixhobo.

Ukuvela kwe-Linear Resonant Actuators (LRAs) kutshintshe ngokupheleleyo umdlalo. Ingqiqo yabo ephambili ayikokujikeleziswa kodwa "yi-resonance"—ngoyilo olunobuchule lwesakhiwo, izinto zangaphakathi zivelisa ukungcangcazela okuphezulu kwiifrikhwensi ezithile, zibonelela ngempendulo "emfutshane, enamandla, nechanekileyo" enokuthi i-motors zemveli zingakwazi ukuyifanisa.

Ukuze siqonde umahluko, masithelekise ii-LRA nee-motor ze-Eccentric Rotating Mass (ERM) ezisetyenziswa kakhulu:

Umgaqo Wokusebenza: Ii-ERM zixhomekeke kwiisisindo ezijikelezayo ezingaqhelekanga ukuze zenze amandla angalinganiyo kunye nokungcangcazela; ii-LRA zisebenzisa i-resonance yenkqubo ye-spring-mass, eqhutywa yi-voice coil esebenzisana ne-magnetic field ukuvelisa intshukumo ethe tye (akukho malungu ajikelezayo).

Isantya sokuPhendula: Ii-ERM zifuna ixesha lokukhawulezisa/ukunciphisa isantya, nto leyo ekhokelela ekuqaleni/ekumiseni okulibazisekileyo kunye nempendulo engacacanga; ii-LRA zifikelela kwisantya esivakalayo ngoko nangoko, kunye ne-latency ephantse ibe zero—ifanelekile kwiindlela ezikhawulezayo zokunxibelelana njengokuthayipha okanye ukudlala imidlalo.
