27/70 Dead Band


The reason of the low positioning accuracy of the permanent drive is existence of dead band, where the MMT does not move in spite of magnet movement. In this video, the MMT does not move until the center distance between the MMT and the magnet reaches 500 micrometer. This large amount of dead band deteriorates positioning accuracy of the MMT and thus, it is essential to figure out the dead band cause and counter it.
