Abstract

Much of the time lifting-transport machines operate in transient modes, mostly acceleration and deceleration. There is no doubt that the reasons for the reduction of the efficiency of the machines are instabilities in speed and workloads on these modes, deviations from the optimum values of engine power, and speed and increase of energy losses. Another reason for the increase of energy losses when operating lifting-transport machines is the process of forced braking in case of a necessary stop. Currently, a new class of lifting-transport machines has appeared which can produce regenerative braking. Significant advantages among them have been balanced by the machine having high reliability and service life. However, the methods of calculating the optimum transfer functions in managing the recovery of braking energy up to the end is not yet developed. Below, we consider a mathematical models balanced with the counterweights of elevator systems, the analysis of which reveals the possibility to reduce their energy consumption.
