Abstract

MOTOR PIEZOELECTRICO CON ONDA PROGRESIVA CONSTITUIDO POR UN ESTATOR (1) DE FORMA ANULAR PLANA ASOCIADO A DOS GRUPOS DE ELEMENTOS PIEZOELECTRICOS CILINDRICOS (2,3,4) DE CERAMICA POLARIZADOS Y EXCITADOS POR UNA CORRIENTE ALTERNA CON UN DESFASE DE PI /2 ENTRE LOS GRUPOS PARA GENERAR EN LA SUPERFICIE DEL ESTATOR UNA DEFORMACION CON FORMA DE ONDA PROGRESIVA Y POR UN ROTOR CONFORMA DE DISCO. LOS ELEMENTOS PIEZOELECTRICOS ESTAN CONECTADOS AL ESTATOR MEDIANTE UNA PIEZA DE ACOPLAMIENTO AUXILIAR (5,6,7) DE FORMA TRONCOCONICA Y EN CONTACTO PERMANENTE CON EL ESTATOR POR SU EXTREMO DE PEQUEÑA SECCION. ESTA CONSTRUCCION TIENE COMO EFECTO SUPRIMIR, EN GRAN MEDIDA, LA FLEXION PARASITA DE LOS ELEMENTOS PIEZOELECTRICOS.
