What are the necessary conditions for the stable operation of electromechanical drive systems?
1. The mechanical characteristic curve of the motor n = f (Tm) and the characteristic curve of the production machinery n = f (T) have the intersection point (ie, the balance point of the drag system); 2. When the speed is greater than the equilibrium point corresponding to the speed, Tm & lt; T, that is, if the interference speed is increased, when the interference should be eliminated after the Tm-T <0; and when the speed is less than the equilibrium point corresponding to the speed, Tm> T, that is, if the interference rate of decline, when the interference is eliminated Should have Tm-T> 0
