  5. 接通电源后,电机会发出“嗡嗡”声,不能靠外 力旋转
  5. When the power is turned on, the motor will make a "buzzing" sound and cannot rotate by external force
  失效原因 :(1)定子铁心与转子铁心的相位摩擦:轴承磨损严重,轴承铁心弯曲冲孔变形明显 。(2)转子笼损坏
  Failure reasons: (1) phase friction between stator core and rotor core: bearing wear is serious, bearing core bending and punching deformation is obvious. (2) Rotor cage damaged
  消除方法:(1)转子铁心大修:更换铁心轴检查铁心轴是否弯曲检查铁心冲头,并抛弃铁心冲头凸出部分 。(2)检查转子
  Elimination methods: (1) rotor core overhaul: replace the core shaft, check whether the core shaft is bent, check the core punch, and discard the protruding part of the core punch. (2) Check the rotor
  6. 通电后,电机不“嗡嗡”,但电机无法启动
  6. After power on, the motor does not "buzz", but the motor cannot be started
  故障原因 :(1)电源断开或电源插座松动 。(2)绕组开路(3)绕组短路或过热
  Fault reason: (1) the power is disconnected or the power socket is loose. (2) Winding open circuit (3) winding short circuit or overheating
