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.
Claims23
A control device for a motor having at least two motor parts which interact with each other via a force transmission interface and are movable relative to each other, said control device comprising a sensor for determining a state of movement of the motor parts;
- and a controller for controlling the state of movement of the motor in response to signals of the sensor, said sensor being associated with the force transmission interface of the motor and determining at least one state parameter of the force transmission medium of the motor.
A process of controlling a motor of a type including at least two motor parts which interact with each other via a force transmission interface and are moveable relative to each other, said process comprising the step of registering a state of movement of the motor at the force transmission interface of the motor through determination of state parameters of a force transmission medium of the motor.
