2.1 机械故障。
机械性故障包括电枢动平衡破坏、传动机械不良、安装不良松动、轴承不良、未灌润滑脂或润滑脂太少或太多等问题,主要通过重新校正平衡以及更换相应设备等措施进行故障排查。机械故障是难以避免的,正确解决机械故障可以有效保证电机的正常运行。
2.2 电气故障
直流电机运行的电气故障主要表现在以下几个方面:(1)运行过程中温度升高(2)电刷下火花强烈引起换向片烧黑(3)电机绝缘性能下降,绝缘老化速度加快等。
运行中的温度升高主要由电机过载、冷却系统工作不正常、电枢线圈短路等原因所致。处理过程中要找准引起温度上升的原因,并对相应部位进行检修维护。
电刷下火花强烈引起换向片烧黑的部分原因分析及处理措施如下表:
3结语
直流电机的维护保养决定其正常运行;直流电机结构的特殊性决定其故障的多样性和故障诊断的复杂性。电机的维护保养与故障诊断息息相关,合理的维护不但可以尽量避免故障的发生,延长电机的使用寿命,而且可转化为经济效益。只有正确维护,准确诊断,电机才能实现稳定地运行。

一直以来，冷轧薄板是目前主要短缺钢材品种，数量和质量都不能满足要求。大部分板材深加工生产原料供给不足，对于产品质量要求严格的普冷板及镀锌板，目前主要依赖进口，表面质量、强度级强要求严格的轿车面板进口的比例则更高，供需矛盾非常大。而广东省是冷轧薄板主要消费区域之一，且板材生产能力远不能满足市场需求，缺口尤其严重。数据显示，预计212年珠三角地区将消耗板材超1万吨；广州汽车工业将消耗高质量要求的普冷板及镀锌板超过1万吨、消耗轿车面板2万吨，缺口很大。

二、无刷直流电机的性
电动车辆主要用于城市交通，车辆大部分时间处于启动、加速、制动的工作状态，因此电机的起动性能、加速性能、低速时的效率、制动时的能量再生能力、电机的过载能力、电机的能量密度、电机可靠性对电动车辆尤为重要，是衡量电动车辆电机的重要指标。目前电动车辆还没有专用电机可选，只能选用通用电机，如直流串激电机、直流并激电机、永磁直流电机、异步电机等。通用电机的负载特性为恒负载特性，而电动车辆特性为变负载特性，两者特性不匹配，影响了电机出力，进而影响了电动车辆性能。另外，通用电机的效率点均设计在额定点附近，当负载偏离额定点时，电机效率急剧下降，影响了车辆的续驶里程。开关磁阻电机在低速时具有较大的转矩，但效率偏低，永磁同步电机具有较高的效率，但低速时转矩无法提升。只有无刷直流电机具备了以上电机的所有优点，它具有串激直流电机的低速转矩提升功能、并激直流电机的调速性能、永磁同步电机的特性和接近异步电机的可靠性，非常适合电动车辆的需要。
