Abstract: Disclosed is a stator capable of reducing stress generated in the resin mold of the stator. A stator is provided with a coil formed by coiling a flat conductor, a split stator core provided with a teeth unit for inserting the coil, and a resin mold, which has resin covering the coil ends of the coil inserted into the split stator core. In the stator, an insulator is formed between the split stator core and the coil by way of insert molding, and the resin mold has a cavity, formed in the radial direction of the stator, in between the coil and the end face of the split stator core.

Abstract: A stator structure and a stator manufacturing method which are configured so that the stress occurring in resin-molded sections or insulators of the stator can be reduced. The structure of the stator is provided with coils formed by winding conductors, and also with stator cores provided with teeth to which the coils are mounted through the insulators. The coils mounted to the insulators are resin-molded and integrated with the insulators. Spaces which continue in the radial direction of the stator cores are formed between the insulators and end surface of the stator cores in the axial direction thereof. The insulators and the side surfaces of the teeth of the stator cores are adhered or welded (fusion bonded) to each other.

Abstract: A resin composition includes 0.1 to 40% by mass of a carbon-based nanofiller, 5 to 90% by mass of a resin, and 5 to 90% by mass of calcium fluoride.
