PROBLEM TO BE SOLVED: To provide the commutator motor of a vacuum cleaner which can combine high efficiency and high productivity.SOLUTION: The ratio of the number of segments 18 of a commutator 13, and the number of slots 20 in which a wire 31 is housed radially in one row is set to 1/n (n is an integer of 2 or more). One coil is formed by winding the wire 31 a predetermined number of turns across a pair of slots 20 spaced apart a predetermined slot interval from each other. An armature winding is formed by connecting one wire 31, forming n coils by being wound at one slot interval, between adjoining segments 18. |
