Title: Toru Takeda: Innovator in Rotary Actuation Technology

Introduction

Toru Takeda is a notable inventor based in Azumino, Japan. He has made significant contributions to the field of rotary actuation technology, holding two patents that showcase his innovative approach to engineering.

Latest Patents

One of his latest patents is a rotary actuator that incorporates a PWB motor and a wave gear drive. This design features an axial gap motor, where the motor rotor includes a rotor disk that is coaxially affixed to a hollow motor shaft, along with a rotor magnet attached to the rotor disk. The motor stator is composed of a printed wiring board, which includes an insulating substrate and a motor coil defined by printed wiring. This innovative design allows for a reduction in shaft length and an increase in hollow diameter compared to conventional rotary actuators that utilize SPM motors.

Another significant patent is a magnetic type rotation transmitting mechanism. This mechanism consists of a rotating plate made from a magnetic material and a magnet that transmits the rotational movement of the plate through magnetic coupling. As the rotating plate turns, its oblique edge portions sequentially pass through a magnet-facing area, causing the magnet to rotate about its center axis line due to the magnetic force generated between the magnet and the edge portions. This invention enables the realization of a small and compact mechanism for extracting rotation.
