ULTRASONIC MOTOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 18450121 titled 'ULTRASONIC MOTOR
Simplified Explanation
The patent application describes an ultrasonic motor that consists of a stator and a stator fixing member.
- The stator has a plate-shaped vibrating body with two opposing main surfaces and a through-hole that goes through the body.
- A piezoelectric element is placed on one of the main surfaces of the vibrating body.
- The stator fixing member includes a rotor that contacts the other main surface of the vibrating body.
- The stator fixing member also has a main body portion on the same side as the piezoelectric element and a whirl-stop portion that extends from the main body portion towards the vibrating body.
- The whirl-stop portion and the through-hole of the stator have a polygonal shape when viewed from above.
- The number of vertices of the whirl-stop portion and the through-hole is the same, and they are fitted to each other.
Original Abstract Submitted
An ultrasonic motor is provided that includes a stator having a plate-shaped vibrating body with first and second opposing main surfaces and a through-hole penetrating in a direction in which the first and second main surfaces face each other, and a piezoelectric element on the first main surface. Moreover, a stator fixing member is provided having a rotor in contact with the second main surface, a main body portion is disposed on the first main surface side, and a whirl-stop portion extends from the main body portion toward the vibrating body side. The whirl-stop portion and the through-hole of the stator have a polygonal shape in a plan view. The number of vertices of the whirl-stop portion and the through-hole is the same, and the whirl-stop portion and the through-hole are fitted to each other.
