摘　　要：叙述了新型超声波电机的结构特点、振动子的构造、电极的配置、转子的给电和测量电机特性的实险方法。实验结果显示该电机的转速与理论数学模型很接近,进一步证明了电机的转速恰好等于定子和转子接触面上的两个行进波的相位速度差。这种电机的特点是负载不超过最大扭矩时转速只取决于相位速度差,而与负载无关。This paper presents the structure and characterof a new ultrasonic motor, vibrator constitution; electrodecollocation and measuring method. Our experiments showthat the rotation speed of the motor is equal to the phasevelocity difference between the two traveling waves on thecontact surfaces of rotor and stator. It is confirmed that therotor rotates so as to cancel the phase velocity differencebetween the traveling vibrations along the circumferencesof the rotor. If the load does not exceed the maximum torquethat is determined by the vibration amplitude the rotationspeed is only subject to the phase velocity difference.
