Abstract
A position detection system includes: two magnet rows including a plurality of magnets arrayed cyclically and repeatedly with an array pattern as one cycle in a detection direction, a magnet in the magnet row and a magnet in the magnet row facing each other at surfaces having different polarities at a specific position in the detection direction; a magnetic sensor disposed between the two magnet rows, a relative position of the magnetic sensor relative to the two magnet rows in the X-axis direction being variable; and a determiner that determines a position of the magnetic sensor in an predetermined direction relative to the two magnet rows based on a detection value of the magnetic sensor.
