    • In a 4-pole, 6-slot, 18-segment electric motor, one forward winding coil (91) and two reverse winding coils (92, 93) are wound on each tooth (12). When the forward winding coils are formed of coils corresponding to a U phase, a V phase, and a W phase and the reverse winding coils are formed of coils corresponding to a “−U” phase, a “−V” phase, and a “−W” phase, the coils, which correspond to a U phase, a “−W” phase, a “−W” phase, a V phase, a “−U” phase, a “−U” phase, a W phase, a “−V” phase, and a “−V” phase, are electrically connected in this order between the adjacent segments. When the number of turns of the coils (91) corresponding to a U phase, a V phase, and a W phase is denoted by T1, the number of turns of the coils (92), which correspond to a “−U” phase, a “−V” phase, and a “−W” phase and first come into sliding contact with a brush, is denoted by T2, and the number of turns of the coils (93), which correspond to a “−U” phase, a “−V” phase, and a “−W” phase and later come into sliding contact with the brush, is denoted by T3, “T2>T1>T3” is satisfied.
    • 在4极6槽18段电动机中,在每个齿(12)上缠绕有一个正向绕组线圈(91)和两个反向绕组线圈(92,93)。 当正向绕组线圈由对应于U相,V相和W相的线圈形成时,反向绕组线圈由对应于“-U”相位的线圈,“-V”相位和 “-W”相位,对应于U相,“-W”相,“-W”相,V相,“-U”相,“-U”相,W相的线圈 相位,“-V”相位和“-V”相位在相邻段之间以这种顺序电连接。 当对应于U相,V相和W相的线圈(91)的匝数由T1表示时,与“-U”相对应的线圈(92)的匝数 ,“-V”相位和“-W”相位,并且首先与电刷滑动接触,由T2表示,并且对应于“-U”的线圈(93)的匝数 相位,“-V”相位和“-W”相位,随后与电刷滑动接触,由T3表示“T2> T1> T3”。
