Sunday 1st July 2001

The motor and drive technology in the lift industry have changed quite rapidly within the last three years. The great success of lifts without a machine room has also brought a great number of gearless machines into the field. As a consequence, gearless machines are replacing more and more hydraulic and geared applications. This paper is to highlight today's state of the art gearless technology and it is to introduce a brand-new concept of a small gearless machine with integrated drive.
