Title: Hiromi Ohshita: Innovator in Resolver Technology

Introduction

Hiromi Ohshita is a prominent inventor based in Nagano-ken, Japan. She has made significant contributions to the field of resolver technology, holding a total of five patents. Her innovative designs focus on improving the efficiency and functionality of resolvers, which are essential components in various electrical systems.

Latest Patents

One of her latest patents is an improved resolver that allows the outer periphery of a ring-shaped stator and the inner periphery of a ring-shaped rotor to be directly exposed. This design eliminates the need for a case and a hollow rotating shaft, thereby reducing the overall outside diameter of the resolver. This advancement addresses the challenges faced in reducing the size of prior art resolvers, which were hindered by the presence of a case and hollow shaft.

Another notable patent is related to a stator winding method and structure. In this innovation, the ends of the windings are designed to become entangled with terminals through a longitudinal rod member. When the rod is removed, slack portions are formed, which enhance the vibration and impact resistance of the windings, ultimately preventing breakage.
