Abstract

See full text

An elevator installation and method to passively and reliably generate electrical energy while the elevator installation is in operation utilizes piezoelectric layers. The elevator installation includes an elevator car, a tension member for supporting and moving the elevator car, and a pulley engaging with the tension member wherein the pulley has a piezoelectric layer positioned such that any force imparted to the pulley during engagement with the tension member compresses the piezoelectric layer. As the tension member is driven to move the elevator car up and down along an elevator hoistway it also engages with the rotating pulley. Force imparted to the pulley during this engagement with the tension member compresses the piezoelectric layer which consequently generates electrical energy.
