[0042] Example 1
[0043] Such as figure 1 , figure 2 , image 3 with Figure 4 As shown, the single-drive bidirectional disc-shaped linear piezoelectric motor of the present invention includes a stator and a mover 3 slidable relative to the stator. The stator is composed of a vibrating body and two circular piezoelectric ceramic sheets 2a and a circular piezoelectric The vibrating body is composed of a circular ring-shaped fixed bracket 1a and two identical pot-shaped ring pieces 1b and a pot-shaped ring piece 1c. The pot-shaped ring piece 1b is provided with a protrusion 4a, and the center of the protrusion 4a is provided Through hole, the bowl-shaped ring piece 1c is provided with a protrusion 4b, and the central part of the protrusion 4b is provided with a through hole. The protrusion 4a and the protrusion 4b are in opposite directions; the two bowl-shaped ring pieces 1b and the bowl-shaped ring piece 1c are symmetrically pasted On both sides of the fixed bracket 1a and matc...

[0045] Example 2
[0046] Such as Figure 5 , Image 6 , Figure 7 with Figure 8 As shown, the single-drive bidirectional disc-shaped linear piezoelectric motor of the present invention includes a stator and a mover 3 that can slide relative to the stator. The stator is composed of a vibrating body and 8 arc-shaped piezoelectric ceramic sheets 2a. 2b, arc piezoelectric ceramic sheet 2c, arc piezoelectric ceramic sheet 2d, arc piezoelectric ceramic sheet 2e, arc piezoelectric ceramic sheet 2f, arc piezoelectric ceramic sheet 2g, arc piezoelectric ceramic sheet 2h , The vibrating body is composed of a ring-shaped fixed bracket 1a, two identical pot-shaped ring pieces 1b, and a pot-shaped ring piece 1c. The protruding directions of the pot-shaped protrusions of the two pot-shaped ring pieces are opposite. The central part of the shaped protrusion is provided with a through hole; the protrusion part and most of the ring of the bowl-shaped ring piece 1b are divided into equal ring se...
