Ma LED ibudiriro mukuvheneka kwemotokari, sezvaive zvakaita waya dzemagetsi mukutanga kwezana ramakore rechi20. Marambi pakutanga aishandiswa mumaraiti ekumashure uye mumashure. Shanduko yenzira yakasainwa nemarevhisi anotsvedza akaunzwa mumaXNUMXs.

Apo kufamba mumaguta kwakawedzera zvikuru muma20, mitemo yakadzikwa munyika imwe neimwe kudzivirira nyongano yomumigwagwa. MuGermany, panguva iyoyo zvaidiwa kuti mutyairi aratidze chinangwa chake chokuchinja kwaakananga uye mabhureki, kuitira kuti motokari dziri shure dzigone kuita saizvozvo nokukurumidza. MuPoland, matanho ekutanga ekugadzwa kwemitemo yemigwagwa akaonekwa muna 1921, apo mitemo yakawanda yekufamba kwemotokari mumigwagwa yevanhu yakabudiswa.

Masaini ekutendeuka aratidza kubatsira zvakanyanya mukutevera mitemo yemumigwagwa uye, zvakanyanya kukosha, mukudzivirira kudhumhana kwakawanda. Mushure mekudzvanya bhatani rinoenderana, iyo electromagnet yakaburitsa iyo yekunongedza lever inenge 20 cm kureba kubva paimba, ichiratidzira chishuwo chekuchinja nzira. Gare gare, index lever yakavhenekerwa, iyo yakapa kuti ionekwe zviri nani.

Vagadziri vemotokari vakashandisa zvishandiso zvekunze-pasherufu zvakagadzirwa nevechitatu mapato. MuGermany, chiratidzo chekutendeuka kubva kuBosch, chakaunzwa pamusika muna 1928, chakave chakakurumbira; muUSA, mafemu eDelco aive akakurumbira. Electromagnetic kutungamira zviratidzo zvakangotsiviwa neiyo kusvika zvino inozivikanwa masaini masaini muma50s.
