Summary:Improved transportation comfort, energy efficiency and safety are the top priorities for the modernization of electric drives of the elevator industry. Promising is the transition from two-speed electric drives to frequency-controlled single-speed, which, in its turn, is associated with significant material costs. Therefore, the search for alternative variants of elevator electric drives reconstruction is relevant. Based on the experiments carried out on the mathematical model, it is determined that the developed method for identifying the loading degree of the elevator cabin allows to increase the accuracy of its positioning to ±5 mm due to the change start time of braking.
