In this paper, the following key problems in the ultrasonic motor of longitudinal and torsional vibrator combination type are discussed: mechanism of the motor, polarization and position of piezoelectric ceramic, selection of the shape of the stator, and the optimum design of structural parameters of the motor. A 20mm diameter motor is designed and fabricated. The motor's stalling torque is 2.5 kgf·cm, and the noload speed is 35 r/min. Some problems that demand our attention in the assembly of the mechine are presented. Experiment results show that the frequencies and modes fulfil design requirements.
