| Zusammenfassung: | The utility model belongs to the technical field of piezoelectric motors, and discloses a piezoelectric ultrasonic motor and a laser galvanometer system, a piezoelectric module of the piezoelectric ultrasonic motor is arranged on a mounting seat and made of piezoelectric materials, the piezoelectric module is annular, the axis of the piezoelectric module is parallel to a first direction, the piezoelectric module comprises a first positive electrode, a first motion conversion module is connected to the first positive electrode, and a second motion conversion module is connected to the second positive electrode. The rotor is annular and is rotatably arranged on the mounting base, the axis of the rotor is parallel to the second direction, the first direction is perpendicular to the second direction, the first motion conversion module can abut against the end face of the rotor to drive the rotor to rotate, and the first motion conversion module can be driven to vibrate by applying alternating voltage to the first |
