Example Embodiment
[0028] Example 1
[0029] combine figure 1 and figure 2 , the structure of the motor winding skeleton of the present invention will be described in detail. The winding skeleton includes a body 11 with a cylindrical structure. Preferably, the material of the body 11 is any one of aluminum alloy, magnesium-aluminum alloy and titanium alloy, all of which have the advantages of light weight and high mechanical strength, When the winding skeleton moves along the motor stator 2 in a high frequency and fast linear motion, it can provide sufficient supporting force and tensile and torsional strength. The top surface of the main body 11 is provided with an upper cover 12 for position limiting, and a terminal 13 is installed on the upper plane of the upper cover 12 . On the outer surface of the main body 11, there are four blocking pieces 111 arranged around the circumference of the main body 11 and arranged in the axial direction. The blocking pieces 111 are higher than the side ...
Example Embodiment
[0032] Example 2
[0033] The present invention also provides another embodiment of the linear voice coil motor, which is different from Embodiment 1 in that the annular structure formed by splicing multiple discrete magnetic tiles 222 is replaced with a single annular magnetic tile, and two The above-mentioned single annular structure magnetic tile is connected to the outer magnetic yoke body 21 through an aluminum ring 221, and a pressure ring 223 is installed on the top of the single annular structure magnetic tile at the upper part. Using the above solution can greatly reduce the difficulty of processing and assembly, and make the overall structure of the linear voice coil motor simpler, thereby effectively reducing the failure rate and solving the problem of cumbersome replacement and maintenance caused by damage to the dispersed magnetic tile 222.
