                         piezoelectric transducer used for ultrasonic motors

With the development of society, Ultrasonic motors have become more and more indispensable.electromechanical energy equipment of hifu ultrasound piezo is used for human beings. Piezo ceramic cylinder is a common important equipment in the industry, agriculture, transportation, national defense engineering, and daily life. With the continuous development of ultrasonic motor technology, the ultrasonic motor manufacturing industry has developed in three directions.

First, for the traditional small and medium-capacity ultrasonic motor, this motor is basically a low-voltage 380V power supply, power is not too large, piezo ceramic ring is often used in small pumps, light industry and other occasions; the second is to develop large-capacity direction, such as water turbine generator, mine hoisting, ventilation And large mechanical drive and control occasions, this kind electric power supply of piezoelectric plate sensoris often 660V, 690V, even 6KV, 10KV power supply; The third is toward the direction of miniaturization, that is, micro-motor.

Micro-motor refers to the principle, structure, performance, role and others are different from the conventional motor, and the volume and output power of the motor is very small. Its outer diameter is generally less than 130 mm, and the power is from several hundred milliwatts to several hundred watts. piezo plates vibration sensor is widely used in military and civilian modern equipment and its control systems, such as artillery control, missile guidance, aircraft autopilot, CNC machine tools, shuttleless loom control, industrial sewing machine control, telemetering and remote control, audio and video equipment, automation instruments and Computer peripherals, etc., all piezo ceramic sphere use a variety of micro-motors. At present, a application of representative and practical is an ultrasonic motor.
