Title: **The Innovations of Eiji Yanai: Advancements in Fan Motor Technology**
Introduction
Eiji Yanai, a notable inventor based in Yonago, Japan, has made significant contributions to the field of motor technology. With two patents to his name, Yanai has demonstrated a commitment to enhancing the functionality and efficiency of fan motors.
Latest Patents
Yanai's two latest patents focus on innovative designs for fan motors. The first patent introduces a fan motor featuring a pair of ball bearings positioned near each end of the bearing race. This innovative design includes a series of projections placed around the center of the bearing race, which effectively axially locates both ball bearings. Additionally, low-profile projections are formed between the neighboring projections, extending from one installation point to another for the respective ball bearings. This structure ensures that the ball bearings are supported properly, enhancing performance and stability.
The second patent presents a fan motor that allows for improved contact with the thrust plate. By inserting a shaft through a sleeve bearing and attaching a stopper against the thrust plate, the design ensures that contact occurs solely on a circular contact area. This innovation guarantees uniform sliding of the thrust plate against the sleeve bearing, even if the stopper is slightly inclined. As a result, localized wear and mechanical noise are minimized, improving overall operational efficiency.
