Patent ID: 7019430

Claim:
An electric motor, wherein a plurality of conductive segments formed from flat copper wire are inserted in slot portions formed in a core of a stator, and a coil is constructed by joining different conductive segment leg portions that are brought into contact by folding leg portions of the conductive segments protruding from the slot portions, characterized in that notches are formed in positions facing edge portions of the flat copper wire of the slot portions in stator end plates laminated as part of the core of the stator, and wherein an insulation paper is inserted between the conductive segments and the slot portions formed in the core of the stator including the stator and plates, and wherein at corner portions, in the direction wherein the conductive segments are folded, of the corner portions of the slot portion, notches are formed to extend to at least one of a first position radially outward from an outer edge of the slot portions and a second position radially inward from an inner edge of the slot portions.
