Embodiment approach 1
[0037] 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 equal parts, and the six different positions of the mover 7 relative to the stator 8 determine the position of the mover winding. power-on state.
[0038] When the mover 7 moves to the right in the x direction, the winding sequence is as follows:
[0039] I, X C The phase mover winding 1 is energized, at this time the mover teeth 12 of phase A are aligned with the stator teeth 10, and the mover 7 moves to the right by 1 / 6 of the stator pole pitch 9, which is 2mm;
[0040] II, X C Phase mover winding 1 and X B The phase mover winding 2 is energized at the same time, at this time, the B phase mover teeth 13 are aligned with the stator slot 11, and the mover 7 moves to the right by 1 / 6 of the stator pole pitch 9, which is 2mm;
[0041] III, X B The phase mover winding 2 is energized, at this time th...
Embodiment approach 2
[0050] The displacement movement of the mover 7 changes periodically, and the movement cycle is equal to the stator pole distance 9, which is 18mm. Each cycle is divided into six equal parts, and the six different positions of the mover 7 relative to the stator 8 determine the position of the mover winding. power-on state.
[0051] When the mover 7 moves to the right in the x direction, the winding sequence is as follows:
[0052] I, X C The phase mover winding 1 is energized, at this time the mover teeth 12 of phase A are aligned with the stator teeth 10, and the mover 7 moves to the right by 1 / 6 of the stator pole pitch 9, which is 3mm;
[0053] II, X C Phase mover winding 1 and X B The phase mover winding 2 is energized at the same time, at this time the B phase mover teeth 13 are aligned with the stator slot 11, and the mover 7 moves to the right by 1 / 6 of the stator pole pitch 9, which is 3mm;
[0054] III, X B The phase mover winding 2 is energized, at this time the...
Embodiment approach 3
[0059] The displacement movement of the mover 7 changes periodically, and the movement cycle is equal to the stator pole distance 9, which is 24mm. Each cycle is divided into six equal parts, and the six different positions of the mover 7 relative to the stator 8 determine the position of the mover winding. power-on state.
[0060] When the mover 7 moves to the right in the x direction, the winding sequence is as follows:
[0061] I, X C The phase mover winding 1 is energized, at this time the A phase mover teeth 12 are aligned with the stator teeth 10, and the mover 7 moves to the right by 1 / 6 of the stator pole pitch 9, which is 4mm;
[0062] II, X C Phase mover winding 1 and X B The phase mover winding 2 is energized at the same time, at this time, the B phase mover teeth 13 are aligned with the stator slot 11, and the mover 7 moves to the right by 1 / 6 of the stator pole pitch 9, which is 4mm;
[0063] III, X B The phase mover winding 2 is energized, at this time the C...
