Title: Masahiro Jyono: Innovator in Spindle Motor Technology
Introduction
Masahiro Jyono is a prominent inventor based in Ozu, Japan. He has made significant contributions to the field of motor technology, holding a total of 7 patents. His innovative designs have advanced the functionality and efficiency of various devices.
Latest Patents
Among his latest patents is a spindle motor, which features a stator core comprising a plurality of salient pole portions. These portions are formed in a radial shape, wound with a stator coil, and disposed at a uniform angle, except for a non-equiangular pitch region. The design includes a circular outer peripheral yoke that is continuous with the outer peripheral side of the salient pole portions. Additionally, a cut-out is formed by cutting out part of the outer peripheral yoke in an approximate sector shape, except in the non-equiangular pitch region. A compensating pole plate is provided in the cut-out along the ends on the inner peripheral side of the non-equiangular pitch region where the salient pole portions are formed.
Another notable patent is for a dynamic pressure bearing motor. In this design, a magnet for trapping abraded powder is disposed in a connecting passage between an opening of a sleeve and an opening of a hydrodynamic bearing motor. The components, including a shaft, sleeve, thrust flange, and thrust main plate, are made of austenitic stainless steel. This configuration enhances the cleaning process by preventing the flow of abraded powder to the outside of the motor.
