Abstract
The invention relates to control device and control process for motors. In order to prevent phase distortion and the like in controlled systems, a sensor (250) for detecting the state of movement of a motor (200) is provided directly on or in the force transmission interface (270) of the motor. The sensor can, for example, determine the position, speed or acceleration directly. The invention is particularly suitable for controlling linear motors in high-precision applications, such as machine tools, milling machines or pick-and-place robots.
