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.
摘要翻译：一种用于刷换换电动机的电枢，其具有用于减少刷电弧和电磁干扰（EMI）的分布式线圈绕组装置。绕组模式包括将第一线圈卷绕到衔铁的第一对槽中。然后，具有第一子线圈部分的第二线圈被缠绕到与第一线圈相同的狭槽中，而第二线圈的第二子线圈部分被卷绕成一对狭槽，该一对狭槽由与第一对线槽的一个槽位置偏移。两个线圈部分具有相同的匝数，并且两个线圈部分的总匝数等于第一线圈的匝数。然后将第三线圈缠绕在与第二线圈的第二子线圈部分相同的狭槽中。第三线圈具有与第一线圈相同的匝数。电枢周围重复这种模式。在每个时隙电枢的两个线圈中，这种图案使得每个线圈的磁轴能够相对于与其耦合的换向器条保持在恒定的角度位置，而不需要使用两个线圈的两个线圈部分的不均匀匝数每个分段线圈。

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 segmenting each coil into first and second subcoil portions with differing pluralities of turns. Each subcoil portion is wound around separate pairs of spaced apart slots of a lamination stack. Adjacent coils are wound such that one subcoil portion of each is wound in a common slot to therefore form an overlapping arrangement of each pair of adjacently coils. The winding pattern serves to “shift” the resultant magnetic axes of each coil in such a manner so as to significantly reduce brush arcing and the EMI resulting therefrom. The reduction in EMI is sufficient to eliminate the need for EMI reducing components, such as chokes, which have typically been required to maintain EMI to acceptably low levels. Commutation efficiency is also improved by the distributed winding pattern described above because of the reduction in the unevenness of the magnetic coupling between adjacent coils.
