The ultrasonic frequency adjustable generation power supply is taken as the research object, and based on the micro controller MKE06Z128VLK4 of NXP Semiconductors Corporation as the control core, the core component of ultrasonic motor piezoelectric ceramics is deeply studied, and several parameters affecting piezoelectric ceramics are discussed; The operating mechanism and overall performance of ultrasonic motors were studied On the basis of theoretical research on ultrasonic motors, starting from the stator design of ultrasonic motors, the design and production process of ultrasonic motors are introduced in detail. An experimental prototype of a traveling wave ultrasonic motor is designed and manufactured. Finally, the performance of the designed ultrasonic motor prototype is tested and analyzed through experiments, and several main parameters that affect its operating characteristics are discussed Using DDS technology to solve the problems of high-frequency driving power supply and digital control required for ultrasonic motors, a dual channel signal generator with adjustable phase relationship was designed. The frequency and phase difference control accuracy of the signal was high. Two signal generation schemes, namely changing the frequency division ratio and changing the phase accumulation step, were used to achieve the driving control of ultrasonic motors, and comparison and research were conducted In order to further study several factors that affect the operating characteristics of ultrasonic motors, a control system for ultrasonic motors was established through a combination of software and hardware. Real time control of motor operating parameters was carried out through computers, laying the foundation for the design of closed-loop control of ultrasonic motors in the future
