Patents by Inventor Shinji Koda

Shinji Koda has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 12003139
    Abstract: The rotating electric machine includes a stator having a stator winding and a rotor facing the stator in a radial direction. The rotor includes a carrier having a disk-shaped end plate section fixed to a rotating shaft and arranged coaxially with the rotating shaft, and an annular magnet unit arranged coaxially with the rotating shaft. The magnet has a cylindrical magnet holder whose one end in an axial direction is fixed to the end plate section, and a magnet fixed to a peripheral surface on a stator side in the radial direction in the magnet holder and having an alternating polarity in a circumferential direction. The magnet holder is made of a non-magnetic material. In the magnet, an orientation of an axis of easy magnetization on a q-axis is deviated from an orientation parallel to the q-axis.

  • Publication number: 20230299625
    Abstract: A rotary electric machine includes a rotor including a plurality of magnetic poles, a stator including a multi-phase stator winding, a power line that supplies power to the stator winding, and a rotation sensor that detects a rotational position of the rotor. The stator and the rotor face each other on the inner side and the outer side in the radial direction. The power line and a signal line that extends from the rotation sensor are provided so as to extend in the axial direction. Blocking portions that block an electromagnetic field generated by the power line are each interposed between the power line and the signal line.
