Abstract
An electromechanical stator includes an actuator section, a support section and a spring section. A continuous sheet of elastic material constitutes at least a part of each of these sections. The actuator section includes a vibration body and a moved-body interaction portion. The vibration body includes an electromechanical volume. The spring section is elastic, with a spring constant, enabling provision of a normal force in the vibration direction upon displacement of the fixation point. Also an electromechanical motor and a method of operating such an electromechanical motor are disclosed.
