From HEIDENHAIN Corporation
The semiconductor industry and automation technology increasingly require more precise and faster machines in order to satisfy growing
demands on miniaturization, quality, and manufacturing cost reduction. Linear motors are gradually becoming more important in such
highly-dynamic applications with one or more feed axes. The benefi ts of this direct drive technology are low wear, low maintenance, and
higher productivity.
However, this increase in productivity is possible only if the control, the motor, the machine frame, and the position encoder are optimally adjusted to one another. Direct drives place rigorous demands on the quality of the measuring signals. Optimum measuring signals reduce vibration in the machine frame, stop excessive noise exposure from velocity-dependent motor sounds, and prevent additional heat generation, so allowing the motor to realize its maximum mechanical power rating.
