A linear piezo-electric ultrasonic motor using a single flexural vibrating bar for electro-discharge system industrial applications
The development process of a linear piezoelectric ultrasonic motor using a single flexural vibrating bar was developed. The process covers the conceptual design, methodology, modelling and analysis, principle of operation, testing and evaluation. The motor comprises: the stator, rotor and sliding element. It provides a linear motion that can be driven by a common driving system with electrical signal of invariable frequency. The test results of EDS industrial applications showed that this prototype is able to provide a reversible directional of motion, no-load travelling speed equal to 28mm/s, maximum load of 0.78N, a resolution <50μm and a dynamic response <10ms.
