Title: Innovations of Yoshichika Fukuda
Introduction
Yoshichika Fukuda is a prominent inventor based in Kawasaki, Japan. He has made significant contributions to the field of electric motors and compressors, holding a total of 5 patents. His innovative designs focus on enhancing the efficiency and performance of electric motor technology.
Latest Patents
Fukuda's latest patents include a magnet embedded rotor, an electric motor utilizing the same rotor, and a compressor that operates with the same motor. The magnet embedded rotor features permanent magnets embedded in the iron core of the rotor at fixed intervals. Notch parts are formed at the first protruding part and on both sides of the first protruding parts on the outer face between salient poles in the iron core of the rotor, corresponding to multiple permanent magnets. Non-magnetic parts are designed to prevent the short circuit of magnetic flux at both edges of the permanent magnets. The bridge part between the non-magnetic parts and the notch parts is narrowed to induce magnetic saturation, and one or multiple second protruding parts extend towards the outer face at the notch parts. The permanent magnet rotor type electric motor incorporates different configurations and materials for the permanent magnets used for magnetic poles of opposite polarities, thereby increasing the selecting range for magnetic flux density and reluctance torque.
