bumsound Posted March 24, 2011 Share Posted March 24, 2011 mi-am luat din targ o bormasina cu acumulator si s-a stricat butonul de pornire, adica nu mai regleaza turatia progresiv cu apasarea acestuia,ci merge doar la maxim. aveti idee cum as putea rezolva problema?

dan cod Posted March 24, 2011 Share Posted March 24, 2011 Daca-i luata din targ cei care le vand (daca este noua)vand si butoate cel putin la noi in oradea e plin de asemenea butoane de masini de gaurit etc. Link to comment Share on other sites More sharing options...
luk81 Posted March 24, 2011 Share Posted March 24, 2011 Merita sa incerci sa-i desfaci butonul sa vezi cu ce variaza tensiunea. De obicei se pot repara Link to comment Share on other sites More sharing options...
blazeu Posted March 30, 2011 Share Posted March 30, 2011 Parca a scris un coleg pe forum ca la astea pe accu se regleaza cu un PWM care comanda un MOS-FET cu rds-on mic...Cel mai adesea se buleste potentiometrul.... Link to comment Share on other sites More sharing options...
