Abstract

LA INVENCION SE REFIERE A UN MOTOR SUPERSONICO CON UN ACTUADOR APLICABLE, ESPECIALMENTE EN MOVIMIENTO LINEAL, MEDIANTE ELEMENTOS PIEZOCERAMICOS EXCITABLES EN MOVIMIENTO. SE HA PREVISTO QUE LOS ELEMENTOS (20,24) PIEZOCERAMICOS DISPONGAN AL MENOS DE UN OSCILADOR (14) DE FLEXION Y UN MOVIMIENTO ELIPTICO QUE RESULTA DE LAS OSCILACIONES LONGITUDINALES Y TRANSVERSALES, QUE SE ENCUENTRAN EN CONTACTO DE ROZAMIENTO CON EL ACTUADOR (12) A SER ACCIONADO.
