Title: Naoto Koshino - Innovator in Rotary Electric Machines
Introduction
Naoto Koshino is an inventor based in Toyota-shi, Japan. He has made significant contributions to the field of rotary electric machines. His innovative approach focuses on enhancing the design and functionality of stators used in these machines.
Latest Patent Applications
Naoto Koshino has filed a patent application for a "STATOR FOR ROTARY ELECTRIC MACHINE, AND ROTARY ELECTRIC MACHINE." This application describes a stator that includes a stator core, a stator winding, and insulation paper sheets. The stator winding is constructed by forming a Y connection of phase windings, which are created by inserting conductor segments into slots from the lower end side of the stator core. The distal end portions of the conductor segments protrude from the upper end side of the stator core. One of the insulation paper sheets is strategically placed between radially adjacent joint portions in the U-phase winding, which are closest to the U-phase terminal. Similarly, insulation paper sheets are arranged for the V-phase and W-phase windings. The surfaces of other joint portions are covered with insulation resin. This design ensures that insulation paper sheets are positioned between joint portions requiring long creepage distances, while the insulation resin covers surfaces of joint portions that do not require such distances.
Conclusion
Naoto Koshino's work in the field of rotary electric machines showcases his innovative spirit and dedication to improving technology. His patent application reflects a thoughtful approach to enhancing the efficiency and safety of electric machines.
