Latest Patents

Muneo Chiba holds a patent for an ultrasonic motor and its driving mechanism. This electrostrictive revolution type ultrasonic motor features a piezoelectric ceramic disk-shaped stator and a rotor. The stator exhibits eccentric movement through excitation by two-phase pulse-like voltage. The rotor, which is fitted around the circumference of the stator, transmits rotating torque due to the eccentric movement via frictional contact. The rotor is made from a plastic material through injection molding, which helps reduce size variation and ensures stable contact with the stator. This design achieves high and stable rotating torque while minimizing production costs. Additionally, the driving device for the ultrasonic motor varies the frequency of the applied voltage in a stepped manner, optimizing motor currents and enhancing efficiency.
