Conception of a Piezoelectric Micromotor
Ultrasonic Motors are drive systems used in a lot of industrial applications notably because of their advantages i.e. no audible noise, compact size and fast response. Therefore, this technology has been chosen for the design of a new type of actuator for the electronic opening of doors. When the electronic identification system detects an authorized user, the coupling balls (lock) are removed from the stator by the motion of the rotor which opens the door.
