Abstract

The invention discloses a radial and axial multi-vibrator ultrasonic linear motor, which mainly comprises a motor stator with a central hole and a motor rotor which penetrates through the central hole, wherein the motor stator mainly comprises a stator shell as well as a radial vibrator groove and an axial vibrator groove on the stator shell; the radial vibrator groove and the axial vibrator groove are arranged in a radial direction and an axial direction respectively along the central hole; one end of the radial vibrator groove is communicated with the central hole, and the left side or right side of the radial vibrator groove is provided with a spring groove which is communicated with the radial vibrator groove; the axial vibrator groove is arranged at the right side or left side of the radial vibrator groove, and communicated with the radial vibrator groove; and the radial vibrator groove is internally provided with radial vibrators, the axial vibrator groove is internally provided with axial vibrators, and the spring groove is internally provided with springs. The invention also discloses an operating method based on the radial and axial multi-vibrator ultrasonic linear motor. The invention has the advantages that the thrust is high, the efficiency is high, the loss is low, the speed is quick, and the service life is long.

Description

technical field [0001] The invention relates to a radial and axial multi-vibrator ultrasonic linear motor and its working method, which are suitable for positioning and driving in various occasions such as precision measurement, metering, office automation equipment, industrial appliances, household appliances, robots, automobiles, aerospace equipment, etc. . Background technique [0002] Ultrasonic linear motor is a motor that uses piezoelectric material crystals to deform under the action of an external electric field as a driving force to generate linear motion. This ultrasonic linear motor has the following characteristics: [0003] 1. It does not need to be like other types of linear motors. It converts electrical energy into mechanical energy for linear motion based on the principle that the current-carrying conductor receives electromotive force in a magnetic field. [0004] 2. There are no coils and iron cores in the stator and mover parts, and the structure is sim...
