Embodiment Construction
[0022] The embodiments of the present invention are described in detail below: the present embodiment is implemented under the premise of the technical solution of the present invention, and detailed implementation and specific operation process are provided, but the protection scope of the present invention is not limited to the following implementation example.
[0023] This embodiment includes a stator and a rotor, wherein the stator includes a stator base body 31 and a longitudinal vibration piezoelectric sheet 11 and a torsional vibration piezoelectric sheet 21 pasted thereon, and the stator base body 31 is uniformly distributed on a hollow cylinder. The four planes are used to paste the longitudinal vibration piezoelectric sheet 11 and the torsional vibration piezoelectric sheet 21. The longitudinal vibration piezoelectric sheet 11 and the torsional vibration piezoelectric sheet 21 are installed symmetrically and used in pairs; the rotor 61 runs through the stator and pas...
