Latest Patents

Igarashi holds a patent for a rotating electric machine. This invention improves cooling capacity by increasing the width and depth of a gas vent groove formed in a creepage block. The design prevents fractures near the face of the creepage block, which abuts against a magnetic winding. The creepage block is fabricated from a resin material containing reinforcing fibers, which are strategically disposed to form straight and curved lines along the contour of the gas vent groove. This configuration increases the area of the interlayer slip face, reducing the shearing force per unit slip area and preventing shearing slip fractures.
