starting torque

The synthesis of the structure of the automatic control system of direct current motors is carried out, and the methodology of the study of the duration of the transient process during the control of the direct current motor is presented. A study of the influence of the regulator parameters on the duration of the transition process was carried out, which allowed to choose the optimal ones for the criterion of the minimum duration of the transition process

The expediency of use of slow-speed (multiblade) wind-wheels with sail-type blades on the territories with low wind potential is substantiated. The structure of experimental prototype of horizontal-axis wind0wheel with sail-type blades is proposed. The technique of determination of blades inclination angles influence on the starting torque of the wind-wheel is presented.
