PROBLEM TO BE SOLVED: To provide a commutator motor achieving high efficiency.SOLUTION: The commutator motor including an armature and a commutator provided coaxially with the armature is provided with a turbulent flow prevention member at the connection between the commutator and an armature winding to thereby reduce the windage loss and high efficiency of the commutator motor is achieved. The turbulent flow prevention member of a resin 73 constituting a molded structure is disposed. The turbulent flow prevention member of the resin 73 covers a convex and concave shape of a hook portion 41 in which the commutator 40 and the armature winding 13 are electrically connected to each other, jumper wires and an area adjacent to the edge portion on the outer circumference, and a core of the armature at the armature side. |
