Display

Linear motors in display manufacturing. The manufacturing of displays requires a machine that can move high masses, regularly in a vacuum environment to prevent contamination of the display. This requires one or multiple motors with a high force output, especially when the vacuum limits the performance.

The amount of time that we spend looking at an electronic screen is significant. Televisions, smartphones, and computer screens all have one thing in common, the screen is typically a flat-panel display. The manufacturing of these flat-panel displays is challenging due to the high moving mass and the patterning steps of the display take place inside a vacuum.

Outside placement

For some applications it is useful to use iron core vacuum magnet plates in combination with a standard iron core motor to perform better movement. In this case, the motor is placed outside the vacuum and the magnet plates inside the vacuum. The airgap between the two will be bigger than normal, resulting in some force loss. However, the iron core motor outside the vacuum can still generate more force than the ironless vacuum motor. Also, the iron core motor has better cooling possibilities outside the vacuum environment.
