| Popis: | 93 A new type of piezoelectric linear motor by means of traveling wave is developed. The linear motor comprises of the stator and the carriage. The stator fundamentally consists of a meander-line structure and a gear teeth mounted on the meander-line structure is focused in this study. The meander-line structure with bimorph actuators laid in a line driven by two sets of AC power with phase difference can generate traveling wave. The traveling wave is transferred to the carriage by the gear teeth, and thus forms a linear motor. Modeling of the meander-line structure and the contact layer and the carriage is derived. Simulation by ANSYS and practical experiment are carried out to examine the function for several different key parameters and verify their approximation. Practical experiment is also carried out to show the performance of output speed and load bearing. Large load bearing is an advantage of the developed piezoelectric linear motor. |
