The purpose of this paper is to develop a control method of the spherical ultrasonic motor with a magnetized rotor using the phase control method. This paper proposes a new measurement method to detect the orientation of the rotor. The orientation of the magnetized rotor is detected by three-hall devices embedded at the center of each stator. This paper will describe the magnetization method of the rotor, the mechanism and method for detecting the orientation of the magnetized rotor as well as the result of the experiment.
