换向器是一个由许多燕尾状的梯形铜片间隔云母片绝缘排列而成的圆柱体，每片换向片的一端有高出的部分，上面铣有线槽，供电枢绕组引出端焊接用。所有换向片均放置在与它配合的具有燕尾状槽的金属套简内，然后用V形钢环和螺纹压圈将换向片和套筒紧固成一整体，换向片组与套筒、V形钢环之间均要用云母片绝缘。
（3）转轴 在转轴上安装电枢和换向器。
3．气隙
静止的磁极和旋转的电枢之间的间隙称为气隙。在小容量电机中，气隙为0.5～3mm。气隙数值虽小，但磁阻很大，为电机磁路的主要组成部分。气隙大小对电机运行性能有很大影响。

永磁直流无刷电机永磁直流无刷电动机的学名叫“无换向器电机”或“无整流子电机”，是一种的无级变速电机，它由一台同步电机和一组逆变桥所组成，具有直流电机那样良好的调速特性，但是由於没有换向器，因而可做成无接触式，具有结构简单，制造方便，不需要经常性维护等优点，是一种理想的变速电机。

直流电机具有响应快速、起动转矩较大、从零转速至额定转速可提供额定转矩的性能。但直流电机的优点也正是它的缺点，因为直流电机要产生额定负载下恒定转矩，则电枢磁场与转子磁场须恒维持90°，这就要藉由碳刷及整流子。碳刷及整流子在电机转动时会产生火花、碳粉，除了会造成组件损坏之外，使用场合也受到限制。交流电机没有碳刷及整流子，免维护、坚固、应用广，但特性上若要达到相当于直流电机的性能须用复杂控制技术才能达到。现今半导体发展迅速功率组件切换频率加快许多，提升了驱动电机的性能。
