Abstract
Provided is a motor capable of having an improved output while keeping the mechanical strength of the stator core. A motor includes: a stator including a stator core including an annular yoke having an outer part and an inner part and teeth extending inwardly from the inner part of the yoke, and a coil wound around the teeth; and a rotor rotatably disposed inside of the stator. The stator core includes the lamination of sheet members made of a soft magnetic material. Each sheet member has a binding part to bind the sheet members in the lamination at a first part corresponding to the outer part of the yoke. At least the binding part of the first part is made of an amorphous soft magnetic material. The sheet member has a second part other than the first part, and the second part is made of a nanocrystal soft magnetic material.
