摘　　要：电动工具作业期间,串励电机转子换向器与碳刷之间产生的火花过大可引发噪声和电磁干扰等不良现象。换向器表面质量欠佳时,不仅促使电机产生机械火花,同时也影响碳刷与换向器表面氧化膜的形成。针对影响换向器车削质量的诸多因素,探讨换向器表面车削方法、质量要求以及相应的检验方法,旨在有效地提升电机综合使用寿命。During the operation of electric tools,excessive sparks between the rotor commutator of series motor and the carbon brush may cause undesirable phenomena such as noise and electromagnetic interference.When the surface quality of the commutator is poor,it not only makes the motor produce mechanical sparks,but also affects the formation of oxide film on the carbon brush and commutator surface.In view of many factors affecting the turning quality of commutator,the turning methods of commutator surface,quality requirements and corresponding inspection methods are discussed in order to effectively improve the comprehensive service life of the motor.
