けたことを特徴とする超音波モータ。 Two sets of piezoelectric parts are bonded to the outer periphery of one surface of the stator, and a traveling wave can be generated by applying driving high frequency voltages having a phase difference of 90 degrees to the two sets of piezoelectric parts, In an ultrasonic motor in which the rotor is pressed against the other surface of the stator via a spring material, and the rotor is driven and rotated by a traveling wave generated in the stator, the radial center portion of the stator is fixed to a substrate, A first magnet is attached to the substrate side of the stator at an intermediate position between the radial center and the outer circumference, and a second magnet that repels the first magnet is attached to the substrate at a position opposite to the first magnet. Ultrasonic motor.
