Latest Patents

One of his latest inventions is the vibration wave linear motor, which features a unique configuration. In this motor, coupled driving contacting parts are positioned on the top and bottom of a vibrator unit. The mechanism includes two guide shafts that contact concave parts of the driving contacting elements, supported by erecting parts of a supporting structure. The design incorporates a lower guide shaft that is pressed upward by spiral springs, effectively sandwiching the vibrator. By applying alternating current voltages of different phases to the vibrator unit, the motor generates a vibration wave, enabling the creation of elliptical rotation vibrations in the driving contacting parts. This results in coordinated movement between the vibrator, guide shafts, and supporting framework, allowing for enhanced relative motion in the shaft direction where either the guide shafts or the vibrator can be fixed, driving an attached object.
