move from its path, and is directed upwards by the
positive polarization.
By reducing the flow of current through the coils, the
strength of the electromagnet reduces and the elevator
starts descending. Thanks to the built-in electromagnetic
brakes the elevator spends electricity only when it goes up,
and when it goes down it does not spend any energy. In
the case of a power failure as a safety measure there is a
synchronous motor on each guideway, that is powered by
a battery filled from a solar panel, and is sufficient to
descend the elevator to the ground floor until the power
supply is restituted.
