The invention discloses a planar two-degree-of-freedom ultrasonic motor structure, and relates to the technical field of electromechanics. The motor structure comprises a motor shell, an output component and an elastic body; a mounting cavity is formed in the motor shell, a mounting port communicated with the mounting cavity is formed in one side of the motor shell, and an output port communicatedwith the mounting cavity is formed in the side, opposite to the mounting port, of the motor shell; one end of the output component penetrates through and extends out of the output port, and the otherend of the output component is connected with the elastic body; the bottom of the elastic body is connected with a friction material layer and the elastic body, the bottom of the elastic body is connected with the friction material layer, and the top of the elastic body is connected with a piezoelectric ceramic layer. According to the planar two-degree-of-freedom ultrasonic motor, the output formof the ultrasonic motor is expanded, the application field of the ultrasonic motor can be effectively expanded, and the planar two-degree-of-freedom ultrasonic motor is compact in structure, simple in process and convenient for market popularization and industrial production.
Description
technical field [0001] The invention relates to the field of electromechanical technology, and can be used in the fields of optical instruments, detection systems, precision machining, weapons and military industry, and more specifically relates to a planar double-degree-of-freedom ultrasonic motor structure. Background technique [0002] Ultrasonic motor is a kind of drive that uses mechanical vibration in the ultrasonic frequency domain as the driving source. It has the characteristics of low speed and high efficiency, compact structure, self-locking when power is off, and no electromagnetic interference. In recent years, with the acceleration of the development of intelligent weapons at home and abroad, the application of ultrasonic motors in the field of weapons has attracted more and more attention. At present, the common ultrasonic motors on the market mainly have two structural modes, one is a linear motor with single-degree-of-freedom motion, and the other is a rotar...
