Title:
NON-CONTACT RUNNING TYPE ELEVATOR
Document Type and Number:
WIPO Patent Application WO/2008/029764
Kind Code:
A1
Abstract:
Running of an elevator cage is guided with a small power supply capacity and in
a non-contact way while suppressing the maximum power required upon start of
guidance. The elevator includes guide devices (5a to 5d) for running-guiding
the cage (4) by a magnetic force function in a non-contact way. That is, the cage
floats over guide rails (2a, 2b). The guide devices (5a to 5d) are controlled
so as to generate a magnetic force associated with at least two operation axes
(x, y, θ, ξ, ψ axes) of the cage (4). Here, upon guidance start,
control is performed only for some of the operation axes and control for the other
operation axes is started when a predetermined time has elapsed after the guidance
start.
