Ingani nzira dzekuyedza dziripo dzePCB electromagnetic zvikamu?

Kuedza PCB electromagnetic zvikamu chikamu chakakosha chePCB bvunzo. Saka, ingani nzira dzekuyedza dziripo dzePCB electromagnetic zvikamu?

1.Zvakajairika coil test

Kuyedza coil, bhiriji redhijitari rinogona kushandiswa kuyedza inductance online. Nekuti iyo frequency yekushanda kweiyoinductor coilkazhinji haina kuderera, iyo inductance inogona kuedzwa pane frequency pamusoro pe10kHz.

2. Transformer coil bvunzo

Nekuyedza inductance D kukosha kweiyo coil huru yetransformer, tinogona kuona kana iyotransformerine inter-turn short circuit. Iyo chaiyo nzira ndeye: isa dhijitari bhiriji ku0.3V kana pazasi, 10kHz kana pamusoro, uye kuyera kukosha kweD kweiyo huru coil inductance. Kana iyo D yakakosha kupfuura 0.1, inotongwa kuti shanduri yakakuvadzwa uye haigone kushandiswa.

3. Kuonekwa kweHoro zvishandiso

Horo sensors inowanikwa mune imwe chete magetsi uye maviri maviri magetsi emagetsi, pamwe neazvino kubuda mhando uye voltage inobuda mhando. Imwe magetsi emagetsi sensor haione zvazvino, uye chiratidzo chekubuda chinowanzo 1/2 yesimba rimwe chete. Kana yazvino iri 0, chiratidzo chinobuda chinotsauka zvakanyanya kubva pakukosha kwepakati. Iyo sensor inogona zvakare kuyedzwa kuwanda kuti uone kana iyo Imba sensor yakakuvadzwa. Iyo Hall sensor ine mbiri mbiri magetsi ekupa inobuda 0 voltage painonzwa 0 ikozvino; painonzwa kunze kwe 0 ikozvino, iyo yakanaka, yakaipa uye ukuru hwemhepo inobuda inoshanduka nehukuru uye kutungamira kweiyo induced ikozvino.

4. Kuedzwa kwerelays

Zvikanganiso zvakajairika zverelays zvinosanganisira kubviswa kwecoil, macontacts asiri kuvhara, kukwirira kuonana kuramba, uye kutsva mabatiro. Nzira yakanakisa yekuyedza kuti relay yakajairika ndeyekupa simba relay, shandisa iyo yakayerwa voltage kune coil, uye wozoyedza kuenderera mberi kwekubata.

Pamibvunzo yechigadzirwa, ndapota tarisa iyochigadzirwa peji, unogamuchirwawotaura nesukuburikidza neruzivo rwekusangana pazasi, isu tichakupindura iwe mukati me24.
