Fig. 1 is an exploded view of a mover assembly according to an embodiment of the present utility model. Referring to fig. 1, a mover assembly provided by an embodiment of the present utility model includes a mover core 1.
The number of mover cores 1 may be plural. One mover core 1 has a first connection portion 11, the other mover core 1 has a second connection portion 12, and the first connection portion 11 of the one mover core 1 is connected with the second connection portion 12 of the other mover core 1 to splice the one mover core 1 with the other mover core 1 to form a mover core combination.
The first connection portion 11 may be inserted into the second connection portion 12.
The first connection portion 11 may be a protruding portion, and the second connection portion 12 may be a groove, in which the protruding portion is located. The convex part can be teeth, and the groove can be a buckling position; the teeth are inserted into the buckling positions, so that the two rotor cores 1 are stably spliced together, and rapid splicing can be realized.
Of course, the first connecting portion 11 may be a pin, and the second connecting portion 12 may be a pin hole.
The first connecting portion 11 and the second connecting portion 12 may be connected by overlapping. The first connecting portion 11 is, for example, a stepped structure, the second connecting portion 12 is also a stepped structure, and the two stepped structures overlap and are then fastened by a fastener.
It should be understood that in order to splice at least three mover cores 1 together, a portion of the mover cores 1 has not only the first connection portion 11 but also the second connection portion 12 to achieve connection with the other two mover cores 1. Taking three mover cores 1 as an example, the first mover core 1 has only the first connection portion 11, the second mover core 1 has the first connection portion 11 and the second connection portion 12, and the third mover core 1 has only the second connection portion 12.
In some embodiments, each of the mover cores 1 has the first connection portion 11 and the second connection portion 12, so that each of the mover cores 1 has the same structure, and can be mass-produced by using one mold, which can further reduce production costs.
As can be seen from the above, the first connecting portion 11 of one of the mover cores 1 is connected with the second connecting portion 12 of the other one of the mover cores 1, so that the two mover cores 1 are spliced together, a plurality of mover cores 1 with shorter dimensions can be spliced and assembled into a mover core assembly with longer dimensions, and the mover cores with shorter dimensions can be produced by using a smaller tonnage punching machine and a punching die, thereby reducing the production cost.
Referring to fig. 1, in some embodiments, for any adjacent two mover cores 1, one of the mover cores 1 has a first connection 11 and the other mover core 1 has a second connection 12; in this way, any two adjacent rotor cores 1 can be connected through the first connecting part 11 and the second connecting part 12, so that any two adjacent rotor cores 1 can be spliced, and a plurality of rotor cores 1 with shorter sizes can be spliced and assembled into rotor core combinations with different lengths.
Referring to fig. 1, in some embodiments, the first connection parts 11 are distributed along the thickness direction T of the mover core 1 (for example, elongated teeth), and the second connection parts 12 are also distributed along the thickness direction T of the mover core 1 (for example, elongated grooves), so that the first connection parts 11 and the second connection parts 12 are all connected in the thickness direction T, the connection between the first connection parts 11 and the second connection parts 12 is increased, and the connection between the first connection parts 11 and the second connection parts 12 is more sufficient, thereby enabling the two mover cores 1 to be reliably spliced together.
It should be understood that the foregoing thickness direction T may be the Y-axis direction.
Fig. 2 is an exploded view of a mover assembly according to another embodiment of the present utility model. Referring to fig. 2, the mover assembly may further include a coil winding 2.

Each bobbin 3 is located between one mover core 1 and one coil winding 2 to insulate one mover core 1 from one coil winding 2, forming a single mover core coil combination.
When the current linear motor rotor assembly is wound, because the rotor core comprises a plurality of rotor teeth, a single coil winding needs to be wound manually, and then a wire frame with the coil winding is assembled in the rotor teeth of the rotor core, so that the production efficiency is low.
The rotor assembly provided by the embodiment of the utility model has the advantages that the single rotor core coil combination comprises the rotor core 1, the coil winding 2 and the wire frame 3, the coil winding can be wound on an automatic winding machine, and then the coil winding and the other rotor core coils are combined and spliced together to form the rotor assembly, so that the production efficiency can be improved, and the production time can be saved.

The mounting portion 13 is used to mount the mover assembly to an external object (e.g., to a load).
The mounting portion 13 may be a hole or a boss, in particular.

Along the height direction H of the mover core 1, the mover teeth 14 are located below, and the first and second connection portions 11 and 12 are located above, that is, the first and second connection portions 11 and 12 are located above the mover teeth 14. The height direction H may be a Z-axis direction.
An open space 30 (or a semi-closed slot) for accommodating the coil winding 2 is formed between the mover teeth 14 of the adjacent two mover cores 1, so that the coil winding 2 can be conveniently placed. In practical application, the wire frame 3 may be placed on the rotor core 1, then placed on an automatic winding machine to wind the coil winding 2, and then the wound rotor cores 1 are spliced together, so that the coil winding 2 is located in the open space 30.
Referring to fig. 1, in the height direction H, the first connection portion 11 and the second connection portion 12 are located above the mover teeth 14, so that two mover cores 1 can be spliced together on one side and the coil winding 2 can be placed between the two mover teeth 14 on the other side, preventing installation interference from occurring, and facilitating operation.
It should be understood that the mover assembly formed by the plurality of mover cores 1 being spliced together includes a plurality of open spaces 30 and a plurality of mover teeth 14.
