Latest Patents
One of his latest patents involves a motor that includes a rotor and stator. The stator features a stator iron core with a substantially annular yoke and multiple teeth extending from the yoke toward the rotor. Each tooth has an extending portion with a winding wire wound in a concentrated manner to form a coil, along with flange portions extending circumferentially from the tip end of the extending portion. The design includes adjacent first and second teeth with coils having identical phases, and adjacent third and fourth teeth with coils having different phases. Notably, the first magnetic resistance from the tip end of the first flange portion to the center of the extending portion of the first tooth is higher than the second magnetic resistance from the tip end of the second flange portion to the center of the extending portion of the third tooth.
Another significant patent by Okuyama features a rotor with permanent magnets that have different coercive forces. This rotor includes an iron core and a series of permanent magnets housed in magnet slots, which are arranged magnetically in series. Additionally, a flux barrier is provided close to the end in a direction orthogonal to the main magnetic flux for at least two of the permanent magnets. The design ensures that two instances of the flux barrier corresponding to the permanent magnets communicate with each other, enhancing the overall performance of the motor.
