PURPOSE:To present an oscillation motor for enabling rotation output to be efficiently generated by enabling the motor to be rotated in the double direction with simple mechanism. CONSTITUTION:An oscillation motor has a stator section and a rotor section. The stator section includes piezo-electric elements 42, 44, electrode plates 46, 48, and first and second block bodies 50, 52. Then, respective members for composing the stator section by inserting a connecting rod 54 into the penetration hole of the stator section and by caulking the tip are fixed to be pressure- welded in the laminated direction. Then, in a state that the second electrode plate 48 is earthed, to split electrode plates 46U, 46V, 46W arranged on rings, three-phase AC voltage with the resonance frequency of bending oscillation is applied. AS a result, on the rotor contact surface 60 of the metallic block body 50, elliptic oscillation in the forward direction and reverse direction is arbitrarily generated, and the rotor section is driven to be forward rotated and reversely rotated. |
