Patent ID: 8896179

Claim:
A motor comprising: a stator having a plurality of magnetic poles disposed in a circumferential direction along an outer periphery thereof; a rotor disposed rotatably around the outer periphery of the stator; and a magnet disposed in a circumferential direction along an inner periphery of the rotor, wherein: the stator has a laminated body formed with sheet-like plates laminated in an axial direction; sheet-like plates of the laminated body located on one axially outermost side comprise a flat portion substantially perpendicular to the axial direction, an extended portion extending outwardly in substantially parallel to the axial direction and a boundary portion connecting the flat and extended portions, wherein the extended portion is formed with two or more sheet-like plates laminated together on the one axially outermost side which terminate correspondingly with each other; and the outermost sheet-like plate of the sheet-like plates comprises a magnetic flux impeding section made thinner than a remaining section of the outermost sheet-like plate, wherein the magnetic flux impeding section is extensive with the boundary portion.
