摘要： A stator includes a stator core and an insulator. The insulator includes a main body and a wall. An adhesive is attached to a portion of a triangular gap between the wall of the insulator and a yoke of the stator core. The adhesive is expandable, and adheres and fixes the insulator to the stator core by expanding to fill in the gap by being heated. Also, a stator manufacturing method includes attaching an adhesive to the wall of the insulator or an inside wall of the yoke, installing the insulator on a tooth, and heating the stator core and the insulator.

摘要： A stator includes an annular stator core, a stator winding, and an insulating sheet member. In the stator core, slots are circumferentially arrayed. The stator winding includes conductor segments having oblique portions formed by open end portions being circumferentially twisted. The open end portions are inserted into the slots from one of two axial-direction sides and extend towards another one. The insulating sheet member is interposed between an inner wall surface of the slot and the conductor segment. The insulating sheet member is rolled into a cylindrical shape along the inner wall surface of the slot, and includes an overlapping portion and a slack portion. In the overlapping portion, two circumferential-direction end portions overlap each other. The overlapping portion is disposed on one of two radial-direction sides of each of the slots. The slack portion is disposed on another one of two radial-direction sides of each of the slots.

摘要： Molded devices are made by a molding method comprising use of magnetic fields to place magnetic particles into optimal configurations. The optimal configurations are set in place by the curing of a continuous solid-forming mixture that surrounds the particles. An example system uses urethane monomers to set iron powder mixtures into an inner and outer core of an electromagnetic coil. In addition to attractive forces to concentrate ferromagnetic particles, repulsive forces may be used to concentrate diamagnetic particles of aluminum or copper.

摘要： A coreless electromagnetic machine includes a dual rotor and a stator. The dual rotor is adapted to rotate about an axis, and includes inner and outer rotor segments. The outer rotor segment is spaced radially outward from, and axially aligned to, the inner rotor segment. The inner and outer rotor segments radially define an annular chamber. The stator is disposed, at least in-part, in the annular chamber.

摘要： An object of the present disclosure is to provide a production method for a stator in which a breakage of the stator core can be prevented when coils are mounted thereon. The present embodiment is a production method for a stator that includes a stator core having a tooth and includes a coil wound around the tooth. The method includes: a step of preparing a stacked body which has the tooth and in which a plurality of plate-like soft magnetic materials each including an amorphous structure are stacked; a step of mounting the coil on the tooth; and a step of, after the coil is mounted, heating the stacked body to a temperature equal to or higher than a crystallization temperature of the soft magnetic materials.
