Title
(EN) ELEVATOR MACHINE WITH COUNTER-ROTATING ROTORS
(FR) MACHINERIE D'ASCENSEUR AVEC ROTORS CONTRE-ROTATIFS
Abstract
(EN)
An elevator drive machine having two counter-rotating rotors provides a lightweight, efficient machine that eliminates reaction torque on surrounding structures by directing reaction forces and driving forces to the elevator car being lifted.
(FR)
Cette invention se rapporte à une machinerie d'entraînement d'ascenseur comportant deux rotors contre-rotatifs, qui est constituée par une machinerie légère et efficace éliminant le couple de réaction sur les structures environnantes en dirigeant les forces de réaction et les forces d'entraînement sur la cabine d'ascenseur devant être mise en mouvement.
