ULTRASONIC MOTOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 18603443 titled 'ULTRASONIC MOTOR
The abstract describes an ultrasonic motor with a unique case structure and bearing configuration.
- The motor includes a case with a plate-shaped first case member and a cup-shaped second case member.
- A first bearing portion supports the shaft and is attached to the first case member.
- The second case member has support portions that protrude inward to support the first case member and fixing portions to secure the two case members together.
- A second bearing portion attached to the second case member supports the shaft.
Potential Applications: - Robotics - Automotive systems - Industrial machinery
Problems Solved: - Improved stability and support for the motor shaft - Enhanced efficiency in converting ultrasonic vibrations into rotational motion
Benefits: - Increased precision and accuracy in motor operation - Reduced maintenance and wear on motor components
Commercial Applications: Title: Advanced Ultrasonic Motor for Precision Applications This technology can be utilized in precision instruments, medical devices, and automation systems, enhancing performance and reliability in various industries.
Prior Art: Researchers can explore prior patents related to ultrasonic motors, bearing configurations, and case structures to understand the evolution of this technology.
Frequently Updated Research: Researchers are continually exploring new materials and designs to further enhance the efficiency and performance of ultrasonic motors.
Questions about Ultrasonic Motor Technology: 1. How does this ultrasonic motor differ from traditional electric motors?
- The ultrasonic motor operates on a different principle, using ultrasonic vibrations to generate motion instead of electromagnetic fields.
2. What are the key advantages of using an ultrasonic motor in precision applications?
- Ultrasonic motors offer higher precision, lower noise, and smoother operation compared to traditional motors.
Original Abstract Submitted
An ultrasonic motor that includes a case having a first case member having a plate shape portion including a first main surface and a second main surface and a side surface connecting the first main surface and the second main surface; a first bearing portion attached to the first case member and that supports the shaft; a second case member disposed on a second main surface side of the first case member, and having a cup shape portion including a bottom portion and a side wall portion, wherein the side wall portion has a plurality of support portions that protrude toward an inside of the case and support the second main surface of the first case member, and a plurality of fixing portions that fix the first case member to the second case member; and a second bearing portion attached to the second case member and that supports the shaft.
