G & G Elevator - Gearless Engine:
It is a new technology that consists of using permanent magnets for its operation . This type of engines have no reducer, which results in a compact machine that does not take up much space, and that, moreover, is quite powerful. They are installed directly in the elevator shaft, reducing the points of friction and, therefore, the noise of the mechanism. It also allows you to save up to 40% in electricity consumption. Gearless engines are more recent than Geared, so their own invention derives from the goal of improving the performance and performance of these.
