Uburyo bwo gukora

1) Ingaruka ya Magnetoelectric

Dukurikije amategeko ya Faraday yerekeye kwinjiza amashanyarazi, ubunini bwingufu za electromotive zatewe muri coil biterwa nigipimo cyimihindagurikire yimikorere ya magnetiki inyura muri coil mugihe co-N-ihindagurika yimuka mumashanyarazi kandi igabanya umurongo wa magneti ( cyangwa magnetiki flux ihinduka yumurima wa magneti aho coil iherereye).

Imirongo igendanwa ya magnetoelectric sensor

Imirongo yimuka ya magnetoelectric sensor igizwe na rukuruzi ihoraho, coil hamwe ninzu ya sensor.

Iyo igikonyo kinyeganyeza hamwe numubiri uhindagurika kugirango bapimwe kandi inshuro yinyeganyeza iba hejuru cyane kurenza inshuro zisanzwe za sensor, kuko isoko yisoko yoroshye kandi ubwinshi bwigice cyimuka ni kinini, biratinda kubice byimuka kunyeganyega (guhagarara) hamwe numubiri unyeganyega. Muri iki gihe, umuvuduko ugereranije umuvuduko wa magneti na coil wegereye umuvuduko wo kunyeganyega wa vibrateri.

Ubwoko bwa rotary

Icyuma cyoroshye, coil hamwe na magneti ahoraho birakosowe. Ibikoresho byo gupima bikozwe mubikoresho bya magnetiki byashyizwe kumubiri wapimwe. Igihe cyose iryinyo rizungurutswe, imbaraga za rukuruzi zumuzunguruko zikora hagati yibikoresho byo gupima nicyuma cyoroshye gihinduka rimwe, kandi magnetiki nayo ihinduka rimwe. Inshuro (umubare wa pulses) zingufu zamashanyarazi zatewe muri coil zingana nibicuruzwa byumubare w amenyo kubikoresho byo gupima n'umuvuduko wo kuzunguruka.

Ingaruka ya Hall

Iyo icyuma gikoresha igice cyangwa icyuma gishyizwe mumashanyarazi, mugihe umuyoboro (mubyerekezo byindege ya fayili perpendicular kumurima wa magneti) utemba, imbaraga za electromotive zibyara mubyerekezo perpendicular kumurima wa magneti hamwe nubu. Iyi phenomenon yitwa Hall effect.

Ikintu cya salle

Ibikoresho bikoreshwa muri Hall ni germanium (Ge), silicon (Si), antimonide indium (InSb), indium arsenide (InAs) nibindi. N-germanium yoroshye kuyikora kandi ifite coefficient nziza ya Hall, imikorere yubushyuhe hamwe nuburinganire. Ubwoko bwa P-silicon ifite umurongo mwiza, kandi coefficient ya Hall hamwe nubushyuhe bwayo nubwa germanium yo mu bwoko bwa N, ariko moteri ya elegitoronike iri hasi kandi ubushobozi bwo gupakira bukaba ari bubi, ntabwo rero busanzwe bukoreshwa nka Hall imwe element.
