Abstract:Based on the piezoelectric and wave equations, the theory of rectangular piezoelectric torsional transducers is established, with the electro-mechanical equivalent circuit and the frequency equation being derived. A satisfactory agreement is obtained between the computed results and experimental.
Keywords:rectangular torsional piezoelectrical transducer  torgue  angular speed  electro-mechanical equivalent circuit
