    • A permanent magnet D.C. electric motor includes a stator housing, permanent magnet structure, and an armature assembly. The armature assembly includes a shaft rotatably mounted in the stator housing, lamination structure, first and second coil windings associated with the lamination structure, a first commutator electrically connected with the first coil windings, and second commutator electrically connected with the second coil windings, each of the first and second commutators being generally cylindrical and having a plurality of commutator segments. Certain segments of the first commutator and certain segments of the second commutator are electrically connected. The motor also includes a brush card assembly including a high speed side having first brush structure associated with the first commutator, and a low speed side having a second brush structure associated with the second commutator, and switches for selectively connecting a D.C. voltage in such a way as to cause the armature assembly to rotate at a first speed and a second speed.
    • 永磁直流电动机包括定子壳体,永磁体结构和电枢组件。 电枢组件包括可旋转地安装在定子壳体中的轴,层压结构,与层压结构相关联的第一和第二线圈绕组,与第一线圈绕组电连接的第一换向器和与第二线圈绕组电连接的第二换向器 所述第一和第二换向器通常为圆柱形并具有多个换向片段。 第一换向器的某些段和第二换向器的某些段电连接。 电动机还包括刷卡组件,其包括具有与第一换向器相关联的第一电刷结构的高速侧和具有与第二换向器相关联的第二电刷结构的低速侧,以及用于选择性地连接这样的直流电压的开关 以使电枢组件以第一速度和第二速度旋转。
