Title: Masahisa Tsuchiya: Innovator in Spindle Motors and Brushless Motors
Introduction
Masahisa Tsuchiya is a prominent inventor based in Isesaki, Japan. He has made significant contributions to the fields of spindle motors and brushless motors. With a total of 2 patents to his name, Tsuchiya continues to push the boundaries of innovation in his industry.
Latest Patents
Tsuchiya's latest patents include a spindle motor and a disk drive unit. This invention features a simple configuration that allows the rotor of the spindle motor to be eccentric in the pickup moving direction. This design improves axial run-out caused by clearance between a rotating shaft and bearing. Additionally, an arc-shaped magnetic body is disposed on the base of the spindle motor opposite a drive magnet, generating an attractive force on the outer periphery side of the rotor.
Another notable patent is for a brushless motor. This invention includes a lubricating oil scattering prevention arrangement provided near a bearing. It effectively prevents the outward scattering of lubricating oil that may leak from between a stator and rotor due to tilting or impact. The design features a plate-shaped rotor case with a descending portion, a step portion, and an outer peripheral portion. A magnet is positioned on the inner side of the outer peripheral portion, while a lubricating oil absorption member is placed between the magnet and the step portion. This arrangement ensures that the lubricating oil absorption member effectively absorbs any leaked lubricating oil, preventing it from leaking outwardly.
