発明の名称 (英語) SPHERICAL ULTRASOUND MOTOR AND CONTROL METHOD FOR A SPHERICAL ULTRASOUND MOTOR
発明の概要(英語) In order to be able to control an approximately spherical rotor precisely even at low rotation velocities, the disclosed control method for a spherical ultrasound motor (1) designates an axis of rotation of a rotor (3) by deciding the phase of a voltage applied to three stators (9a - 9c) when controlling three rotational motions of the spherical ultrasound motor (1). Furthermore, said motor (1) is configured to control the rotational velocity of said rotor (3) by means of adjusting the frequency of the voltage applied to the three stators (9a - 9c). As a result, highly precise control at low rotation velocities is possible.
