Abstract In this paper, a new rotating standing wave ultrasonic motor with multiple driving teeth is proposed. Using the method of adding additional teeth, the correction of the B06 surface of the ultrasonic motor vibrator is expected, the design of the optimum position of the drive tooth is realized. At the same time, a method of reducing the stiffness of the rotor is proposed, and the flexibility is met, the integrated design of the rotor and the pressure device can be realized by removing the disc spring. The accuracy of the finite element analysis is verified by the vibration test of the prototype oscillator. The finite element analysis of the main structure parameters of the influence oscillator mode and natural frequency is carried out. It provides theoretical basis for the design and machining of vibration.

Working Parameters

This paper presents a rotary standing wave ultrasonic motor using single flexural vibration ring transducer. The motor consists of three main components, the stator, rotor and housing unit. The stator is a piezoelectric transducer ring. The rotor is designed of a compact driving wheel and shaft. The housing unit is made of a transparent thermoplastic Perspex material and is part of the motor working mechanism. The motor design, structure, working principles and modelling using finite element analysis is discussed and presented in this paper. A prototype of the motor was fabricated and its characteristics measured. Experimental tests showed that the motor electrical working parameters are: Current: 100 m-amps, Voltage: 100 volts, Frequency: 41.7 kHz, typical speed of 32 revolutions per minute, a resolution of less than 50μm and maximum load of 1.5 Newton.
