WIPO Patent Application WO/2019/181963
Kind Code:
Japanese Patent No. 6085753 discloses an innovative so-called magnetless motor in which a (torque, output/weight) is larger by roughly one digit than a conventional motor due to an innovation in a coil configuration and an iron core structure. In this iron core structure, both end surfaces of a tooth iron core are made to be opposing surfaces in order to reduce the weight, yoke portions are eliminated, and the iron core is epoxy molded in combination with a coil. Therein, a problem exists in the method for retaining the tooth iron cores during a manufacturing step. In the present invention, a mold body having strength based on the principles of steel-framed concrete can be produced by: boring holes (7-1),(7-2),…,(7'-1),(7'-2),… into which tooth iron cores 10 are to be fit in a support substrate (7) made of a non-magnetic high-strength light metal such as a hard aluminum material so that the holes match up with the positions at which the tooth iron cores are arranged; and then tightly fitting the tooth iron cores into the holes and epoxy molding to match the opposing surfaces of the tooth iron cores. Heat generated in the coil is concentrated in the support substrate, and cooling can be achieved by cooling the support substrate.
