The reasons for reducing the efficiency of hoisting-and-transport machines are the variations in speed and load, deviations of which from the optimum value cause an increase in energy losses. Currently, a new class of hoisting-and-transport machines appeared with hybrid power motors that can provide brake energy recuperation and thereby reduce the total energy consumption. However, the article describes a new perspective method for increasing the efficiency of hoisting-and-transport machines by changing the switch time in acceleration-deceleration cycle, the use of which does not require expensive equipment of Brake Energy Regeneration. The results of mathematical modeling showed that the method of reducing energy consumption by changing the time between switching from acceleration to deceleration or vice versa (a point of change) is effective in terms of efficiency and does not increase the cost of the use of energy storage devices.
