ISSUE OF ENERGY EFFICIENCY ASSESSMENT OF ELEVATORS ELECTRIC DRIVES

ELECTRICAL AND COMPUTER SYSTEMS
Abstract. The work deals with the possible assessment of the energy efficiency of modern passenger elevators. Special attention is paid to the issue of recuperation, as the most energy-efficient type of braking. A method is proposed that allows you to qualitatively and roughly estimate the possibility of recuperation in arbitrary elevator electric ...
