The armature may include a coil having inner and outer winding portions separated by an insulator, each of the winding portions comprising a plurality of sheet metal conductors, and a commutator having a plurality of sheet metal commutator segments each being integrally formed with one of the conductors. In one embodiment of the armature, the commutator may have a smaller outside diameter than the outside diameter of the coil. In the same or different embodiment of the armature, the commutator segments may have a width greater than the width of the conductors. The armature may be fabricated from a pair of conductive sheets by forming in each of the conductive sheets a plurality of conductive bands each having first and second conductor portions, shaping the conductive sheets into inner and outer cylinders, positioning the inner cylindrical conductive sheet inside the outer cylindrical conductive sheet, forming a coil from the first conductor portions of the inner and outer cylindrical conductive sheets, and forming a commutator from the second conductor portions of the inner and outer cylindrical conductive sheets.

摘要： An armature for a brush commutated electric motor having a distributed coil winding arrangement for reducing brush arcing and electromagnetic interference (EMI). The winding pattern involves winding a first coil into a first pair of slots of the armature. A second coil having a first subcoil portion is then wound into the same slots as the first coil, while a second subcoil portion of the second coil is wound into a pair of slots that is offset by one slot position from the first pair of slots. The two subcoil portions have the same number of turns, and the total turns of the two subcoil portions equals the number of turns of the first coil. A third coil is then wound in the same slots as the second subcoil portion of the second coil. The third coil has the same number of turns as the first coil. This pattern is repeated around the armature. In a two coil per slot armature, this pattern enables the magnetic axis of each coil to be maintained at a constant angular position relative to the commutator bars to which it is coupled without the need for using uneven numbers of turns for the two subcoil portions of each segmented coil.

摘要： An arc length in contact with a commutator of two brushes in a rotational direction of a motor is defined as not more than 5% of an outer rim length or circumference of the commutator, i.e., not more than πA/2O, where A is an outside diameter of the commutator. A number of shorted segments of the commutator, which short is caused by the brush, can be minimized so that reduction in output of the motor can be prevented. As a result, the motor employed in a car product or an electric tool can be downsized and made lighter.
摘要翻译：与电动机的旋转方向上的两个电刷的换向器接触的电弧长度被定义为不大于换向器的外缘长度或周长的5％，即不大于piA / 2O，其中A是换向器的外径。换向器的多个短路段，其由电刷引起的短路可以最小化，从而可以防止电动机的输出的减小。因此，汽车产品或电动工具中使用的电动机可以被小型化并且变得更轻。
