Title: Ryoji Saneshige: Innovator in Brushless Motor Technology

Introduction

Ryoji Saneshige is a notable inventor based in Yonago, Japan. He has made significant contributions to the field of motor technology, holding a total of 6 patents. His innovative designs have paved the way for advancements in brushless motors and bearing devices.

Latest Patents

One of Saneshige's latest patents is a brushless motor that features a stator core with multiple salient poles arranged in a circumferential direction. This design includes a winding wire wound around the salient poles through an insulator. The rotor of the motor is equipped with a tubular rotor yoke that surrounds the stator, along with an annular magnet for detent torque positioned in the inner peripheral portion of the winding wire. Additionally, a magnetic member is coupled to the interior surface of the ceiling portion of the rotor yoke, opposing the magnet for detent torque.

Another significant invention is a bearing device that comprises a slide member and a holding member, both made of porous-sintered metal. The slide member supports a rotational shaft, while the holding member secures the slide member. The unique construction allows for a greater density in the slide member compared to the holding member, enabling continuous lubrication through capillary action. This design enhances abrasion resistance and extends the service life of the bearing device, while also allowing for a smaller and thinner construction.
