Example Embodiment
[0017] Example 1:
[0018] The invention relates to a linear oscillation motor, see figure 1 , Which includes an outer stator, an inner mover, and a hollow winding slot on the outer stator, wherein the outer stator is a hollow structure, the inner mover is sleeved in the hollow structure, and the hollow winding slots are along the outer stator The axis is arranged in the extending direction. There are multiple hollow winding slots. Each hollow winding slot is an independent ring structure. They are formed around the axis of the outer stator. Each independent hollow winding slot is A coil winding is wound. Of course, if the coil winding is wound with multiple turns of wire, the winding direction of the wire in at least one hollow winding slot is the same direction. The above-mentioned hollow winding slot provides winding space for the coil winding, and can fix or position the coil winding.
[0019] The above-mentioned inner mover includes an inner cylinder and a permanent magnet f...
Example Embodiment
[0036] Optionally, the magnetically permeable block can be a complete ring, sleeved in the stator jacket, or it can be a plurality of independent arrangements along the circumference, for example, it can be six. It is understandable that the groove of the magnetically permeable block is used In order to accommodate the fixed coil winding, no matter whether it is complete or not, as long as it can perform a fixed function on the coil winding, it can be seen that it can be complete or several discrete individuals. The following specifically describes the implementation of "multiple independent arrangements along the circumference":
[0037] There can be six magnetic conductive blocks, and the six magnetic conductive blocks are arranged along the circumference and welded and fixed in the stator jacket, and the winding slots on both sides are used to place the coil windings. In order to facilitate understanding, these six magnetic conductive blocks are called magnetic conductive unit...
Example Embodiment
[0043] Example 2:
[0044] Compared with Example 1, the difference is that in the arrangement of the inner ring layer and the outer ring layer, the inner spacer magnet and the outer spacer magnet are integrated, such as image 3 As shown, they can be the same magnet. This is more convenient and quicker in manufacturing. Other aspects are the same as Example 1.
