Stator and motor

Abstract

A stator includes a stator core, a coil formed by winding an electric wire around the stator core, and a terminal electrically connected to the electric wire, wherein the terminal includes a first portion through which a current flows and a second portion formed by reducing a sectional area of a part of the terminal in a direction in which the current flows, and second Joule heat is larger than first Joule heat, and third Joule heat is smaller than the first Joule heat, where the first Joule heat is Joule heat generated in the electric wire when the current flows through the electric wire, the second Joule heat is Joule heat generated in the first portion when the current flows through the first portion, and the third Joule heat is Joule heat generated in the second portion when the current flows through the second portion.
