Introduction of Robot Development Business
Encounter with ultrasonic motors
Piezo Sonic Motor: Piezo Sonic's representative, Mr. Tada, tells the story of the development of long-life ultrasonic motors.
Um 1995, als ich die Universität betrat, waren viele Forscher in der Entwicklung von Robotertechnologien tätig, die Schaltungsentwurf, Softwareentwicklung, Bildverarbeitungstechnologie und Mechanik umfassten. Während meines letzten Studienjahres war ich an einem Projekt zur Entwicklung eines Monderkundungsroboters in Zusammenarbeit mit JAXA beteiligt. Dabei wurde ein Ultraschallmotor aufgrund seiner geringen Größe und des begrenzten Stromverbrauchs als vielversprechender Kandidat ausgewählt. Die Entwicklung eines Ultraschallmotors für den Einsatz in einem Vakuum wurde zu einer wesentlichen Aufgabe für die Entwicklung eines leichten, stromsparenden und dennoch vielseitigen Erkundungsroboters. Seit meiner Kindheit beschäftige ich mich als Hobby mit funkgesteuerten Fahrzeugen, was mein Interesse an Ultraschallmotoren weckte. Mein Forschungsthema war die "Entwicklung von Ultraschallmotoren für den Einsatz in einem Vakuum", was meine erste Begegnung mit dieser Technologie markierte.
Through joint development with JAXA
In collaboration with JAXA, I was fascinated by the versatility of ultrasonic motors, capable of operating in magnetic fields like MRIs and radiation-exposed environments such as nuclear plants. They are lightweight, robust, and maintain their posture even when power is off.
With Mr. Sashida's collaboration, we conducted rigorous tests, including heat, vacuum, radiation endurance, and simulated rocket launch vibrations, resulting in a prototype ultrasonic motor suitable for space.
Motivated to commercialize superior ultrasonic motors, I joined Mr. Sashida's company and contributed to their development.
Piezo Sonic is launched
One year after joining a manufacturer of ultrasonic motors, I was promoted to Director of Engineering and Development. Over the past decade with the company, I've continuously advanced ultrasonic motors, control circuits, and application technologies, accumulating 20 years of experience since my student days. Along the way, I've fostered relationships with clients and collaborators beyond the company's boundaries. Fuelled by a growing aspiration to innovate, I founded Piezo Sonic—a venture aimed at creating groundbreaking ultrasonic motors and related products, serving unmet needs in the market.
Solving Ultrasonic Motor Challenges
Piezo Sonic developed a patented technology that significantly enhances the lifespan of ultrasonic motors by redesigning the motor mechanism and materials. Following this breakthrough, we trademarked the new long-life ultrasonic motor as the Piezo Sonic motor and launched it into the market.
The PSM series of Piezo Sonic's ultrasonic motors not only offer extended lifespan but also feature a 20% increase in maximum torque and controllable speed range compared to conventional products. Additionally, they have been downsized by 25%.
Our product lineup includes the PSM-S series for general environments and the PSM-N series for magnetic field environments, with customization options available for shaft size and length.
Winner of the 2018 Monozukuri Award
For the PSM60 series, the Japan Society for Precision Engineering, which has a long history as an engineering society, recognized our technology and awarded us the "2018 Monozukuri Award". In addition, the PSM series has significantly extended the service life, which has been a disadvantage of ultrasonic motors, making it possible to be newly selected as a candidate motor for higher torque, smaller size, and quieter operation for products that currently use DC motors and stepping motors. Piezo Sonic will continue to support the further development of Piezo Sonic motors and the future of Japanese manufacturing through technology, ideas, and "co-creation" with partner manufacturers.
