摘要： In an electric motor, magnets (4) have two pairs of poles, the number of teeth (9) is 18, and the number of segments (14) of a commutator is 18. Winding wires (12, 25) for forming an armature coil (7) are formed by a first conductive wire (110) or a second conductive wire (120). The winding wire (25) has a first coil winding wire (7A) and a second coil winding wire (7B). The coil winding wires are each wound around four teeth (9) adjacent to each other. An end (31) of the second coil winding wire is connected to a segment (14) adjacent to a segment arranged at a position which is point symmetric with respect to a segment to which an end (30) of the first coil winding wire is connected. According to the invention, in the electric motor capable of changing the rotational speed of the armature by switching application of an electric current among three brushes, vibration and operating noise can be reduced, and mounting of the connecting wires and the winding wires can be facilitated.
