POSITION DETECTION DEVICE FOR MOVABLE MAGNET TYPE LINEAR MOTOR |
摘要 |
The present invention provides a position detector which can detect the position of a mover on the side of a stator, and which realizes detection with high accuracy in a moving magnet type linear motor. In a moving magnet type linear motor including: a stator 2 with a plurality of coils placed in one direction; and a mover 3 with a permanent magnet so placed as to be opposed to the stator 2, a position detector according to one embodiment of the present invention detects the position of the mover 3. The position detector includes a magnetic body 5 fixed to the mover 3. One or two or more coils are selected and a voltage is applied to the selected coil while a current or a voltage induced in a coil adjacent to the selected coil is measured, and the position of the magnetic body 5 that changes in response to the position of the mover 3 is determined based on the measured current or the measured voltage. |
