Abstract
Provided is a stator of a motor which is capable of reducing an iron loss generated in a motor and thereby attaining a high-efficient motor. A stator of a motor comprises a yoke of a tubular shape; and teeth each of which includes an extending portion extending inward in a radial direction of the yoke from the yoke and an increased-width portion formed at a tip end of the extending portion so as to have a greater width than the extending portion in a circumferential direction of the yoke; wherein the extending portion has a narrower portion having a smaller width than a remaining portion of the extending portion.
