    • A brush motor includes a stator with 2P magnetic poles and a rotor which includes a rotor core, a commutator and windings wound on the rotor core. The rotor core includes N teeth with a slot formed between adjacent teeth. The commutator includes M segments represented by Z1 . . . ZX . . . ZY . . . ZM, wherein M, N, P, Y and X are integers and M is odd and greater than N. Each winding includes a start connected to a segment ZX and an end connected to another segment ZY. Each winding includes at least one coil wound about a corresponding tooth or set of teeth. Some of the windings include a plurality of coils wound on different teeth. The total number of turns of the coils for each winding is substantially the same. A winding unit consisting of a plurality of windings is connected between each pair of adjacent segments. ZX and ZY satisfy the following equation: |Y−X|=(M±1)/P.
    • 电刷电动机包括具有2P磁极的定子和包括转子芯,换向器和缠绕在转子芯上的绕组的转子。 转子芯包括N个齿,其中相邻齿之间形成有槽。 换向器包括由Z1表示的M段。 。 。 ZX。 。 。 ZY。 。 。 ZM,其中M,N,P,Y和X是整数,并且M是奇数并且大于N.每个绕组包括连接到段ZX的起始端和连接到另一段ZY的端。 每个绕组包括缠绕在相应的齿或一组齿上的至少一个线圈。 一些绕组包括缠绕在不同齿上的多个线圈。 每个绕组的线圈的总匝数基本相同。 由多个绕组组成的绕组单元连接在每对相邻的段之间。 ZX和ZY满足下列公式:| Y-X | =(M±1)/ P。
