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.
