In recent years, Russia has paid great attention to the theoretical and practical aspects of conservation. Since electric drives consume about 70% of electrici-ty generated, the most substantial savings achieved by using variable speed drives AC and DC. In this article, for the positional DC drive with speed-dependent resistance torque we have developed three energy-saving diagrams for large movements: with a speed limit of the drive; restricted maximum current anchor chain and speed electric motor; restricted maximum and minimum values of the current anchor chain of the motor and the speed of the drive. We have developed software to determine the parameters of energy saving diagrams for large movements of the executive body of the electric DC depending on the speed torque resistance. For the considered energy saving diagrams, which provide large movement of the executive body of the electric DC, depending on the speed of the moment of resistance, it is necessary to provide the following condition – the maximum speed of the executive body of the drive must be equal to the maximum allowable speed value. We have also defined analytical dependences, allowing calculating the consumption of the electric power drive by moving its executive body, in accordance with the proposed diagrams. Realization of the developed positional control DC motor with speed-dependent torque resistance will lead to energy savings

Developed energy saving chart on small movements of the executive body electric DC drive with speeddependen of the movement of resistance. The parameters presented diagrams and identified analytical dependences, allowing to calculate the consumption of electric energy

The optimum speed diagrams were developed for an electric drive actuator depending from speed limit and without speed limit. Ratio between cycle dura-tion and electric power consumption depending on specified movement was identified

In the article we have shown how to synthesize an automatic position control of the executive body of an electric drive with speeddependent moment of resistance
