PURPOSE:To obtain strong and smooth thrust by providing armature coil group in a core and making a field magnet face the core having the armature coil group. CONSTITUTION:A stator armature 11 is formed by providing armature coil 9 group having the first conductor 9a which contributes to a thrust and the second conductor 9b which contributes to a thrust in opposite direction to the first conductor 9a. Field magnets 5-1, 5-2 are respectively opposed on the stator armature 11 on both upper and lower surfaces of the armature 11. N-poles or S-poles of the field magnet 5-1 or 5-2 are detected by a position sensor which is provided in the armature 11, and a current of the prescribed direction is flowed to the coil 9 through a semiconductor rectifier by the output of the position sensor. |
