A joining method for joining a first member having a hole that is opened on at least one surface, to a second member including a material of which a melting temperature is lower than that of a constituent material of the first member, includes: laminating the second member on the first member so as to cover an opening of the hole; and introducing that material of the second member which is softened or melted into the hole through the opening and curing the material of the second member.

Joining method

A joining method for joining together a first member in which fiber material is mixed into a first resin, and a second member that includes at least a second resin, includes abutting the first member and the second member together, and softening or melting the first resin of the first member and the second resin of the second member that are adjacent to abutting surfaces of the first member and the second member; and stirring a joint forming portion formed by the softened or melted first resin of the first member and the softened or melted second resin of the second member, and the fiber material included in the softened or melted first resin of the first member, in a direction inclined with respect to the abutting surfaces, and hardening the joint forming portion.

A stator structure comprises an edgewise coil molded with resin with long ends being exposed, a bus bar connected to both ends of the coil ends, and a pump and injection holes for directly cooling the bus bar.

Bus bar cooling unit for stator structure

In a reactor core, a gap section between a plurality of core material portions is fixed by adhesion through a spacer, and a resin is arranged vertical to the adhering surface between the core material and the spacer, for sandwiching at least a part of the core material. The resin material preferable a molded material.

Reactor core and reactor

Disclosed is a split stator manufacturing method, which is enabled to enhance a production efficiency and to charge a thermoplastic resin between an insulator and a coil by molding the resin. The split stator manufacturing method comprises a setting step of setting an insulator and a split stator core element in a stationary mold and setting an edgewise coil in a movable mold, a resin injecting step of injecting a resin into a cavity with the stationary mold and the movable mold being half-opened, and a clamping step of clamping the stationary mold and the movable mold.

Split stator manufacturing method

A split stator is arranged such that a formed edgewise coil is mounted on a teeth of a split stator core through an insulator, and a resin molded portion is formed excepting long ends of the edgewise coil.
