Flexible Mounting Fixtures for Miniature Mode Switching Ultrasonic Motors

Abstract

The invention discloses a flexible installation fixing apparatus for a minitype mode-conversion type ultrasonic motor. The minitype mode-conversion type ultrasonic motor comprises a rotor, a stator assembly and a motor base. A flexible installation sheet is configured to the stator assembly. A matrix of the flexible installation sheet is an annular thin metal sheet. Installation legs are formed by radial extension of the annular thin metal sheet on an outer ring surface. Outer ring diameter of the annular thin metal sheet is consistent with diameter of the minitype mode-conversion type ultrasonic motor. The flexible installation sheet is embedded in an annular notch opened on a wall surface of the stator assembly. An installation position of the flexible installation sheet on the stator assembly is near a position of a first longitudinal-vibration mode pitch plane generated by the stator assembly. The installation legs of the flexible installation sheet are connected with fixed upright columns fixed on the motor base. The flexible installation fixing apparatus provided by the invention can carry out flexible axial and longitudinal positioning to the motor, is small in effects on operation modes of the motor, can effectively satisfy requirements on fixing and normal operation maintenance of the motor.
