Ikushanda kwemashoko e yakakwira frequency kudzima michina

Uchishandisa musimboti weelectromagnetic induction, kutakura kunoiswa muinductor (coil), uye inochinjika ikozvino yeimwe frequency inopfuudzwa muinductor kuti igadzire inochinjana magineti. Iyo electromagnetic induction yealternating magnetic field inogadzira yakavharwa induced ikozvino muworkpiece-eddy current.

Kugoverwa kweiyo induced ikozvino pamuchinjikwa chikamu che workpiece haina kuenzana, uye ikozvino density pamusoro pechiso che workpiece yakanyanya uye zvishoma nezvishoma inoderera mukati. Chiitiko ichi chinodaidzwa kuti skin effect. Simba remagetsi repamusoro-soro rekushanda rinoshandurwa kuva simba rekupisa, iro rinowedzera kupisa kwepamusoro pepamusoro, kureva, kupisa kwepamusoro kunowanikwa. Iyo yakakwira iyo frequency yazvino, iyo yakakura yezvino density mutsauko pakati peyepamusoro layer uye mukati meiyo workpiece, uye iyo yakatetepa yekudziya layer. Kudzima kwepamusoro kunogona kuwanikwa nekukurumidza kutonhora mushure mekunge tembiricha yekudziya yekupisa yadarika tembiricha yakakosha yesimbi.
