Latest Patents

Among Kawai's most recent inventions are two significant patents. The first, titled "Stator and Motor," involves a motor design featuring a rotor and a stator. This innovative stator is constructed by laminating multiple magnetic thin strips, each designed with various teeth parts. The unique feature of this design includes an elliptical-shaped inner diameter that aligns with the end portions of the teeth parts. In a clever engineering twist, at least one of the magnetic strips is strategically shifted by a specified angle relative to the others. This configuration effectively reduces cogging torque by ensuring that all teeth parts correspond perfectly with each other.

The second patent is for a "Magnetic Gasket and Cooling Apparatus." This apparatus comprises a thermal insulation box, a door, and a magnetic gasket featuring a magnet and a magnet retaining part. The innovative design incorporates a heat insulation sheet situated between the magnet and its retaining part. This arrangement enhances efficiency, particularly when the apparatus is in a closed state, with added functionality on the peripheral surface of the magnet.
