Abstract： |
This invention relates to a vibration linear supersonic motor in a piezoelectric ceramic metal composite plate composed of a stator, a runner outputting moment and a pre-press unit pressing the runner, among which, the stator is composed of eight ceramic plates and a metal plate, a driving foot is set at the side of the metal plate, the ceramic plates are adhered to both surfaces of the metal plate to be polarized along the thickness direction of the stator, an outer electrode is coated on the surface of ceramic plates to excitation electrode for applying electric field along the direction vertical to the ceramic polarized direction and composite vibration is excited on the stator. |
