Abstract
A device and method using the electromechanical properties of piezoelectric materials to generate and deliver electrical power to a high speed electrically powered rotatable shaft. The device has a stationary module that is connected to an electrical source; and has a rotatable module, which is mechanically connected to the electrically powered rotatable shaft. The rotatable module rotates relative to the stationary module. When the stationary module is electrically energized, the stationary piezoelectric component expands and causes the rotatable piezoelectric component to compress. When the rotatable piezoelectric component compresses, it generates electrical power transferred to the electrically powered rotatable shaft. Thus, electrical energy can be delivered to the electrically powered rotatable shaft without a direct electrical connection. The present invention is particularly useful in applications requiring large diameter through-hole dimensions.
