Scheme yejaja ye screwdriver. Sokujaira goroja circuitry

Zvimwe zvemazuva ano zvinogadzirisa zvinoshanda kubva pabhateri. Ivhareji yepamusoro ndiyo 12 mAh. Kuti uone kuti chigadziri chinogara chichishanda mumamiriro ekushanda, unoda goroja. Zvisinei, zvakasiyana zvakanyanya mumhepo.

Mazuva ano mitero inobudiswa pa12, 14 uye 18 V. Zvakakoshawo kuziva kuti vashandisi vanoshandisa zvikamu zvakasiyana-siyana zvejaja. Kuti uchinzwisise nyaya iyi, unofanira kutarisa dheji rejaji yakakwana.

Kutora dunhu

Izvo zviyero magetsi magetsi zvejaja yejasi rinosanganisira chipani chechitatu. Muchiitiko ichi, zvinyorwa zvemufananidzo weV 12 zvinoda mana. Nokugona, vanogona kunge vakasiyana chaizvo. Kuti urongwa hwekugadzirisa hukuru hwemaawa, ma-capacitors anonamatira chip. Izvo zvinoshandiswa pakubhadhara zvose zvemashure uye zvekare. Muchiitiko ichi zvakakosha kufunga nezvezvimwe zvikamu zvemabhatiriyoni chaiwo.

Directly thyristors inoshandiswa mumashandisirwo ekugadzikana kwezvino. Mune mimwe mienzaniso, tetodes yakazaruka yakaiswa. Dzinopesana mukuitisa kune mumwe. Kana tikatarisa kuchinja kwe 18 V, ipapo ikoko kazhinji pane zvinoshambadza dipole. Zvinhu izvi zvinokubvumira kuti utarise nyore nyore kusanganisa mumutambo.

Kuchinja kune 12V

Ijaja yeVV yevheteri (scirdriver batteries) (iyo mifananidzo inoratidzwa pasi apa) ichitsva chemufambisi uye ine simba kusvika kusvika 4.4 pF. Muchiitiko ichi, conductivity munharaunda inosimbiswa pamwero we 9 microns. Kuchengetedza kuti nguva dzemaawa dzisingasimuki zvakanyanyisa, zvinodzivirira zvinoshandiswa. Resistors for model inonyanya kushandiswa mumunda.

Kana tichitaura nezvekubhadhara tetrodes, ipapo pane kuwedzera kwechikamu chekudzivirira. Ane magetsi emagetsi anoputika, anoita zvakanaka. Kuvhiringidza kwakashata kwekubhadhara ne12 V kunoramba kuri 30 ohms. Iyo inoshandiswa kakawanda kuchengetedza mabheteri kwe 10 mAh. Kwemazuva ano ivo vanoshingaira vanoshandiswa muzvigadzirwa zvebazi "Makita".

14 V Vatsigiri

Chirongwa chejaja chekugadzirisa kwe 14 V transistors pachayo inosanganisira zvidimbu zvishanu. Pamwechete, ikozvino kutendeuka chip yakakodzerwa chete neyane-channel. Condensers ye 14 V vhidhiyo vanoshandisa zvinopisa maitiro. Kana tichitaura nezvemabhatiriyo ane simba re 12 mAh, ipapo kunezve tetrodes yakawedzerwa. Muchiitiko ichi, kune didi mbiri pa chip. Kana tichitaura pamusoro pemiganhu yekubhadhara, ikozvino kuitisa kweiyo ikozvino munharaunda, sekutonga, kunodhinduka kusvika ma 5 micrononi.
