Embodiment approach 1
[0036] The displacement movement of the mover 7 changes periodically, and the movement cycle is equal to the stator pole distance 9, which is 12mm. Each cycle is divided into six operating intervals, and the six different positions of the mover 7 relative to the stator 8 determine the mover. energized state of the sub-winding.
[0037] See Table 2 for the energization sequence of the mover windings when the mover 7 moves to the right or to the left in the x direction.
