Title: Toshio Ootani - Innovator in Electric Fan Technology

Introduction

Toshio Ootani is a notable inventor based in Hyogo, Japan. He has made significant contributions to the field of electric fan technology. His innovative designs have led to the development of efficient and effective electric fans that enhance user experience.

Latest Patents

Ootani holds a patent for an electric fan that features a unique design. The electric fan comprises a rotary shaft supported on a mounting base plate. The rotary shaft extends through a cylindrical stator, and at the tip of the rotary shaft, the bottom of a cup-shaped rotor yoke and an impeller are secured. The stator is enclosed in the rotor yoke, which has an anisotropic rotor magnet magnetized in reverse polarity alternately in its circumferential direction. This design allows the stator and rotor to form a DC brushless motor, enabling the impeller to rotate through the rotation of the rotor and the rotary shaft. Additionally, a hall integrated circuit (IC) is provided near the rotor magnet to detect the rotating position of the rotor. Based on the rotating position signal from the hall IC, a microcomputer controls the current flowing period, ensuring that the current flowing through the stator coil partly overlaps between each phase. Another microcomputer adjusts the voltage applied to the DC brushless motor and controls the wind velocity.
