  • PERSONAL ESCAPE DEVICE WITH EDDY CURRENT BRAKING
    Publication number: 20180296860
    Abstract: A personal escape device includes a main housing, a shaft, a magnet housing, and a plurality of magnets. The shaft is rotatably coupled with the main housing and is rotatable about a rotational axis. The magnet housing is positioned in the main housing and is coupled with the shaft such that the magnet housing rotates together with the shaft. The plurality of magnets is coupled with the magnet housing such that the plurality of magnets rotates together with the magnet housing. The stator assembly is coupled with the main housing and surrounds the magnet housing. The stator assembly and the magnet housing are radially spaced from each other to define an air gap therebetween.
