ABSTRACT:
An ultrasonic motor with a stator uniformly made of a material that can convert electrical energy to mechanical energy. The stator includes a first part having two corresponding electrodes for applying a signal to the first part, and a second part, uniformly configured to the first part, having an area adjacent to the first part where the material does not exist. The second part does not exist between the electrodes. A moving element is in contact with the second part and driven by progressive oscillation waves generated in the second part due to the signal applied to the electrodes.
