Title: Takuya Yoshizawa: Innovator in Rotor Technology

Introduction

Takuya Yoshizawa is a prominent inventor based in Saitama, Japan. He has made significant contributions to the field of rotor technology, holding a total of seven patents. His innovative designs focus on enhancing the performance and efficiency of rotary electric machines.

Latest Patents

Yoshizawa's latest patents include a unique rotor design that features a shaft allowing cooling oil to flow through it. This rotor consists of a substantially cylindrical rotor yoke fitted over the shaft, a magnet attached to the rotor yoke, and a first end plate that abuts one end of the rotor yoke. This configuration includes a cooling oil passage formed on the radially inner side of the magnet, enabling the cooling oil to flow in an axial direction. The rotor yoke receives a pressing force in the axial direction via the first end plate, creating a sealing part that effectively seals the cooling oil between the cooling oil passage and the magnet.

Another notable patent is the rotor structure of a rotary electric machine, which aims to provide higher cooling performance than existing designs. This rotor structure features a surface on the side of a rotor core with a plurality of radially extending grooves. Additionally, it includes a first annular groove that extends along the circumference of an insertion hole for the shaft. This annular groove connects to the radially inside end portions of the grooves and a refrigerant supply hole portion of the rotor core, with a depth greater than that of the grooves.
