Title: Innovations of Yoshihiko Yanai
Introduction
Yoshihiko Yanai is a notable inventor based in Aichi, Japan. He has made significant contributions to the field of actuator technology, holding 2 patents that showcase his innovative approach to engineering.
Latest Patents
One of his latest patents is a "Rotation controller for a differential actuator." This invention includes two induction motors and a differential mechanism designed to produce a constant torque on its output shaft based on the differential speed of the motors. The apparatus features two inverters, each positioned between one of the induction motors and a common power source. These inverters have individual voltage and frequency output characteristics, allowing for separate control of the motors' speeds. This innovation ensures that the output shaft maintains constant speeds, regardless of the load torque, by adjusting the setting frequencies on both inverters.
Another significant patent is the "Differential actuator," which comprises a pair of unit actuators enclosed in a housing. The rotational shafts of these unit actuators support bevel gears that are positioned in opposition to each other. These bevel gears work in conjunction with two differential gears, which are rotatably interconnected, to form a differential mechanism. The rotation of the differential gears around the axis of the bevel gears is utilized as the actuator's output.
