Abstract
In a method for controlling three single-phase motors and moving a platform in a direction of the normal, the motors are controlled by one three-phase converter, so that a first motor is operated between a first phase and a second phase of the converter, and a series connection or parallel connection of a second and third motor is operated between a second phase and a third phase of the converter. A platform is adapted to perform this method.
