Piezoelectric vibration wave motor with multiple traveling wave generating members |
摘要 |
In a vibration motor, electrostrictive elements arranged or polarized phase-differentially are bonded to a plurality of concentric ring-shaped vibration members arranged on at least one of a stator and a rotor, voltages are applied to the electrostrictive elements to generate travelling vibration waves in the vibration members and the rotor contacting to the vibration members is friction-driven by the travelling vibration wave.
