Abstract (en)
The lift system (100) has a cage (10) and a counterweight (12), where the cage and the counterweight are connected with each other via cables (14) that is guided by a drive pulley (16). The drive pulley is coupled with an electric machine (20) which is configured to operate as an electric motor for driving the drive pulley and for moving the cage and the counterweight. The electric machine is configured to operate as a generator for recovering the electrical energy as a result of rotation of the drive pulley.
