According to the brush motor 41 of the second example, similar effects as those of the first example can be obtained. For example, downsizing can be performed more easily or higher torque can be achieved with the same size as compared with an existing brush motor. In addition, higher torque can be obtained as compared with the brush motor 1 of the first example. Meanwhile, the number of winding steps decreases with a concentrated-winding structure, and labor and cost required for manufacturing can be reduced as compared with an existing brush motor (for example, a brush motor with six poles and twelve slots) in which the number of magnet magnetic poles 5 is identical to that of the brush motor 41 of the second example and the number of coils is larger. Further, a coil end can be reduced with the concentrated-winding structure, and winding resistance can be reduced. In addition, the pulsation of a current can be increased as compared with the first example, and the use of the pulsation of the current enables sensorless control that does not require an additionally required sensor magnet.
