With a total of 4 patents to his name, Yamada's work has had a substantial impact on the industry.
Latest Patents
Yamada's latest patents include a coil insulator designed for electrical rotating machines. This coil insulator serves as the main insulator for a bundle of conductors formed from multiple insulated wires, which create an armature coil within the rotor or stator core of an electrical rotating machine. The coil insulator features a mica layer, woven or unwoven cloth made from inorganic and organic materials, hexagonal crystal boron nitride particles, and a thermosetting polymer organic resin that connects these components. The orientation of the hexagonal crystal boron nitride particles is aligned with the longitudinal direction of the coil.
Another significant patent involves a coil for electric rotating machines, which is constructed from a conductor formed by bundling square strands and stacking them in a coil configuration. This design incorporates mica tape made from mica paper and glass cloth backing, wound around the conductor, along with an insulation wall created by impregnating and curing resin between the layers of mica tape. The mica tape is supported by inorganic particles using an adhesive that remains insoluble in the impregnated resin.
