    • Disclosed is a motor in which a commutator (10) is provided with connecting wires which short-circuit equipotential segments; brushes (21) are constituted by a low-speed brush (21a), a high-speed brush (21b), and a common brush (21c) used in common by the low-speed and high-speed brushes, and are juxtaposed along the circumferential direction. The circumferential brush width (W2) of the high-speed brush is set to be smaller than the circumferential brush width (W1) of the low-speed brush. The high-speed brush and the low-speed brush are formed so that simultaneous sliding contact with equipotential segments (15) can be avoided. Additionally, armature cores (8) are provided such that a plurality of teeth (12) is point-symmetrical about a rotary shaft (3) at equal intervals in the circumferential direction, and the teeth and slots (13) are formed so as to exist alternately at intervals of 90 degrees in the circumferential direction. By virtue of the above configuration, vibration and noise can be reduced while achieving miniaturization and high performance of a motor.

    • 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.
    • 在电动机中,磁体(4)具有两对磁极,齿数(9)为18,换向器的分段(14)的数量为18.用于形成电枢的绕线(12,25) 线圈(7)由第一导线(110)或第二导线(120)形成。 绕组线(25)具有第一线圈绕组(7A)和第二线圈绕组(7B)。 线圈绕组线分别围绕彼此相邻的四个齿(9)缠绕。 第二线圈绕组线的端部(31)连接到与布置在相对于第一线圈绕组的端部(30)的点对称的位置处的段相邻的段(14) 连接的。 根据本发明,通过在三个电刷之间切换施加电流而能够改变电枢的转速的电动机中,可以减少振动和操作噪音,并且可以容易地安装连接线和绕组线 。
