摘要：
A novel two-degree-of-freedom ultrasonic motor with a single stator was designed, which required a single-phase power to drive rotary and linear motions. A SIDM was proposed which was close to the resonant frequencies. The inertial drive models of the motor was established based on motor construction mechanism and driving principles. The influences of square wave signal parameters on motor performances were analyzed quantitatively. The simulation examples show that the stator surfaces may output suitable sawtooth waves using the asymmetric square wave excitations near the resonant frequencies. The optimum drive frequencies and duty cycles of the square waves are also given. The simple and efficient drive method may eliminate the influences of the phase differences on multiple degree-of-freedom motor performances totally. © 2018, China Mechanical Engineering Magazine Office.
