The Experimental Research of a Piezoelectric Linear Motor
The working principle and driven approach of a piezoelectric linear motor which uses axial stretching vibration of cascading piezoelectric elements is introduced. The prototype of that motor is designed and fabricated. Its performance is also tested. The motors vibrator is a stick and moving object is a cylindrical ring which contacts with vibrating stick in the shape of cylindrical surface. The forward and backward movements of moving object are achieved by utilizing the axial stretching vibration of vibrating stick. The moving direction is altered by changed the frequency of driving signal. The structure of the motor is simple and the power supply is single sine phase. So that it is easy to be smaller. In addition, the thrust force is increased by cylindrical surface contact between moving object and vibrating stick so that it is easy to be practical also. This kind of piezoelectric linear motor is very suitable for precise positioning of objects, fine material handling, and vibration cutting tools.
