Abstract

PURPOSE:To drive a wave motor in a small size and with low power consumption, by providing a GND for an electric signal to make a progress wave necessary for driving a wave motor. CONSTITUTION:A wave motor is constituted in sticking a piezoelectric oscillator group 504 to an electric conductor 503, the electric conductor 503 to an insulator 502, the insulator 502 to an oscillator 501 respectively in order to provide the GND as many as the number of electric signals. The drive circuit is composed of P-type and N-type transistors(Tr) 901-904 and an inverter 909, where the piezoelectric oscillator 1 is driven by the signal inputted to an signal line 905. The circuit thereby gets miniaturized and low in power consumption, so that the voltage applied to the piezoelectric oscillator will be twice as much as the power voltage.
