Abstract

Inventia se refera la un tahogenerator de curent alternativ ca traductor analog, al carui semnal de iesire are amlitudinea si frecventa dependente liniar de turatie. tahogeneratorul este de frecventa medie si de precizie mare, de constructie simpla si sigur în functionare. Recunoasterea sensului de rotatie se obtine în domeniul punctului zero cu limite foarte restrînse ale erorii. Aceasta se realizeaza conform inventiei prin aceea , ca bobinajul indus multipolar este ondulat si montat în întrefier pe materialul nemagnetic, imobil, fiind excitat de catre un flux magnetic cu intensitate variabila. Modificarea fluxului magnetic se realizeaza prin cuplaj maxim si minim-care alterneaza continuu cu bobinajul, latimea bobinei corespunzînd pasului polar. cuplajele magnetice alternate se obtin prin crestaturi corespunzatoare ale circuitului de excitatie, rotativ.
