Mumakumi emakore achangopfuura, maitiro emotokari uye mamwe maindasitiri akawedzera kudiwa kwezvinhu zvitsva zvemagineti.Nekuda kweizvozvo, pakati pe-1990s izvo zvekutanga zvikamu zvakagadzirwa kubvayakapfava magnetic compositevakazvarwa.Uye maitiro ekushandisa aya akapfava magineti composites (SMCs) anongoramba achikura.

Iwo ekutanga eSMC zvikamu aive emagetsi cores, aishandiswa zvakanyanya mumotokari zhinji dzeGM.Iwo akange akakomberedzwa kutenderera, uye hapana tepi inodzivirira yakashandiswa kuchengetedza yekutanga mhepo kubva kune coil.Nekukurumidza kusvika nhasi, uye simbi yehupfu -- uye SMC - tekinoroji yasvika kure.Ramba uchiverenga kuti udzidze izvo zvakapfava zvemagineti makombisi uye chii chinoita kuti zvive zvakakosha kune zvikamu zvemagetsi mumaindasitiri akawanda.
