Embodiment 1
[0046] Such as figure 1 and 2 As shown, the present invention is mainly composed of a motor stator with a central hole and a motor mover 1 penetrating through the central hole. The motor stator is mainly composed of a stator housing and a radial concave The stator housing is mainly composed of the stator housing A33 and the stator housing B34 buckled together, and the radial groove and the axial groove are arranged radially and vertically along the central hole respectively. Axial setting; one end of the radial groove communicates with the central hole, and the left or right side of the radial groove is provided with a spring groove communicating with it; the axial groove is located on the right side of the radial groove Or the left side, and communicate with the radial groove; the radial piezoelectric strip is arranged in the radial groove, the axial piezoelectric strip is arranged in the axial groove, and the spring one is arranged in the spring groove.

Embodiment 2
[0062]Due to the existing piezoelectric materials or components used to manufacture piezoelectric strips, the displacement (stretch) of each power-on and power-off cycle can only be a few thousandths of the device size at most, but can be a few percent The device is still under development, and the technology is very difficult; and the cost of the piezoelectric strip is high. If the displacement (stretching) of each power-on and power-off cycle is to be increased, the usage of the piezoelectric strip will inevitably increase, which will increase the manufacturing cost of the motor. In order to overcome the above shortcomings, increase the displacement stroke of each action cycle, thereby increasing the speed of the motor, making up for the speed of this type of motor and reducing the manufacturing cost, such as Figure 4 and 5 As shown, the present invention is provided with a radial hydraulic displacement amplifying mechanism between the radial piezoelectric strip and the mot...
