Hall firikwensin: manufa da kuma aikace-aikace

Hall sakamako samu da sunan da godiya ga E.G.Hollu masanin kimiyya ya gano shi a 1879 a lokacin da yin aiki tare da bakin ciki zinariya faranti. A sakamakon haka ne bayyanar danniya da ajiye conductive faranti a wani Magnetic filin. Wannan irin ƙarfin lantarki yana da kyau mai suna - da Hall ƙarfin lantarki. Industrial aikace-aikace na wannan sakamako da aka sanya yiwu ne kawai bayan 75 years bayan da aka gano, a lokacin da suka fara a iya samar semiconductor fim da wasu kaddarorin. Saboda haka akwai wani Hall haska manufa na aiki dogara ne a kan eponymous sakamako. Wannan haska ne a na'urar ga aunawa da halin maganaɗisu filin ƙarfi. A ta da asali suna da yawa da wasu na'urorin: na'urori masu auna sigina na kusurwa da kuma mikakke kawar da Magnetic filin, yanzu, ya kwarara, da dai sauransu Hall haska yana da yawan abũbuwan amfãni, godiya ga wanda aka yi amfani da ko'ina. Na farko, da ba-lamba aiki gusar inji lalacewa. Abu na biyu, shi ne mai sauki don amfani a fairly low cost. Uku, da na'urar yana da kananan size. Fourth, canja mitar martani ba ya haifar da wani motsi a cikin minti na ji. Biyar, da lantarki Na'urar haska alama bai fashe yanayi da switched nan da nan dials m. Sauran pluses: siginar watsa ba tare da ikazheniya, wadanda ba lamba yanayin da siginar da kanta, kusan Unlimited sabis rayuwa, Big kewayon mitoci, da dai sauransu Duk da haka, shi ya aikata da ta drawbacks, babban abin da masu kula electromagnetic kutse a cikin wutar lantarki kewaye da wani canji a zazzabi.

The aiki manufa na wani Hall haska. Hall haska - a Slotted zane, gefe daya daga wanda yake shi ne semiconductor, da kuma a kan wasu - wani m maganadisu. Lokacin da na yanzu gudana a cikin Magnetic filin a kan electrons da wani karfi vector wanda shi ne perpendicular zuwa biyu na yanzu da kuma filin. Kamar wancan sasanninta, farantin akwai wani m bambanci. A rata haska wani allo ta hanyar abin da na filin Lines aka rufe. Yana hana samuwar kan farantin m bambanci. Idan da rata ba allon, a karkashin mataki na Magnetic filin da semiconductor farantin an cire m bambanci. Idan allon nassi (na'ura mai juyi ruwan wukake) ta hanyar da rata a shigar da na hadedde kewaye zai zama sifili, da kuma fitarwa ƙarfin lantarki bayyana.

Hall haska kuma na'urorin dogara ne a kan shi ake amfani da ko'ina a cikin jirgin sama, mota, instrumentation da kuma wasu masana'antu. Su ake samar da irin wannan sanannun kamfanoni, irin su Siemens, Micronas Intermetall, Honeywell, Melexis, Analog Na'ura, da kuma waɗansu da yawa.

Mafi na kowa ake kira core na Hall haska fitarwa wanda ya musanya dabaru jihar a lokacin da Magnetic filin wuce wani daraja. Musamman, wadannan na'urori masu auna sigina suna yadu amfani da brushless Motors a matsayin matsayin masu auna sigina na'ura mai juyi (DWP). Dabaru Hall na'urori masu auna sigina suna amfani da aiki tare na'urori, da ƙonewa tsarin, Magnetic katin masu karatu, keys, a contactless canji, da dai sauransu Yadu amfani na game mikakke na'urori masu auna sigina suna amfani da su domin auna mikakke ko kusurwa hijirar da wutar lantarki yanzu.
