Abstract

Dispozitivul de comanda a motoarelor eletrice pas-cu-pas, uzilizabil în actionari electrice de pozitionare precisa cu diverse tipuri constructive de motoare, are la baza metoda alimentarii cu tensiuni sinusoidale a fazelor motorului si prin aceasta o mentinere la valori ridicate a cuplului motor chiar si la viteze mari de deplasare, realizând în acelasi timp o miscare lina si o pozitionare foarte precisa a motorului. Dispozitivul de comanda a motoarelor electrice pas-cu-pas transforma n impuls de tact exterior în tensiuni de comanda sinusoidale, de frecventa proportionala cu frecventa impulsului de tact, care este functie de viteza de deplasare dorita, si defazate între ele în mod adecvat, functie de numarul de faze ale motorului. Dispozitivul este universal putând fi comandat manual sau prin calculator, putându-se programa valoarea curselor, a vitezelor si a legii de variatie a acestora.The step-by-step electric drive control device, usable in precise positioning electric drives with various engine types, is based on a method of feeding sinusoidal motor phase voltages and thereby maintaining high torque values even at high travel speeds, while achieving a smooth motion and a very precise positioning of the engine. The step-by-step power control device transforms the external clock pulse into sinusoidal command voltages, the frequency proportional to the clock pulse frequency, which is a function of the desired traveling speed, and faded appropriately between them by the number of phases of the engine. The device is universal and can be ordered manually or by computer, and can be programmed for the value of the races, speeds and variation laws.
