Title: Akihiko Wakitani: Innovator in Spindle Motor Technology

Introduction

Akihiko Wakitani is a notable inventor based in Ozu, Japan. He has made significant contributions to the field of spindle motor technology, holding a total of 4 patents. His innovative designs have enhanced the efficiency and functionality of spindle motors, which are crucial components in various electronic devices.

Latest Patents

Wakitani's latest patents focus on advancements in spindle motor design. One of his key inventions involves a spindle motor where the teeth portions of a stator core, formed by laminating magnetic plates, are bent to increase the number of turns of the stator windings. This design avoids gaps in the teeth portions between the magnetic plates, allowing for precise attractive force adjustments. The stator core is engineered so that its teeth portions face the surface of a rotor magnet at right angles, ensuring that the teeth portions and salient pole arm portions, around which windings are wound, remain substantially parallel to each other. Additionally, the salient pole arm portions are strategically located approximately halfway between the lower surface of a hub and the upper surface of a base. The thickness of the magnetic plate is also optimized, set to be 0.5 to 0.9 times that of other portions.
