Tuned driving of piezoelectric resonators: impedance matching

Autor: Pons, J. L., Fernández, J. F., Villegas, M., Ochoa, P., Ceres, R., Calderón, L., Rocon, E.

Publikováno v: Boletín de la Sociedad Española de Cerámica y Vidrio, Vol 45, Iss 3, Pp 178-183 (2006)

For optimal operation of piezoelectric resonators, the electrical impedance of electronic drivers and the resonator itself must be matched. Lack of matching results in a non smooth transmission of electrical power between the drive and the load which

Comparación entre sistemas electrocerámicos de desplazamiento mecánico. Motores y actuadores piezoeléctricos

Autor: Mesonero-Romanos, D., Fernández, J. F., Villegas, M., Ceres, R., Rocon, E., Pons, J. L.

Publikováno v: Boletín de la Sociedad Española de Cerámica y Vidrio, Vol 43, Iss 4, Pp 725-731 (2004)

Piezoelectric motors can be classified as resonant or forced response motors. As to resonant motors, travelling wave motors, either rotary or lineal must be highlighted. These devices have several features that make them different as compared to any

Modelling of the travelling wave piezoelectric motor stator: an integrated review and new perspective

Autor: Rodríguez, H., Ceres, R., Calderón, L., Pons, J. L.

Publikováno v: Boletín de la Sociedad Española de Cerámica y Vidrio, Vol 43, Iss 3, Pp 698-705 (2004)

Articles from different areas which are closely related to the modelling of the stator of travelling wave ultrasonic motors (TWUMs) are reviewed in this work. Thus, important issues relevant to this problem are identified from the areas of vibration
