Abstract

To increase the torque of a travelling wave type ultrasonic motor (USM), a special $Gamma$-shaped support structure is proposed and studied. Its effect on the transverse amplitude and the contact area of the stator and rotor has been studied by FEM. In addition, to enhance the motor torque further, a twinvibrator structure is equipped. Experimental results indicate that some significant improvement in the torque performance characteristic can be achieved.
