ZQ—650_(-1)型700千瓦脉流牵引电动机用于韶山1型电力机车。原设计由于磁极引线及磁极绕组与磁极铁芯间没有适当固定措施,因而当电机运行时,受机车振动的影响在疲劳应力作用下造成磁极引线断裂,据运用部门初步统计,此故障率占电机总故障率的30％左右。这一质量事故会导致电机烧损、换向不良甚至环火。为了防止磁极引线断裂,其主要途径是将 ZQ-650 _ (- 1) 700kw pulse traction motor for Shaoshan Type 1 electric locomotive. The original design due to the magnetic pole leads and pole winding and pole core is not properly fixed between the measures, so when the motor is running, the impact of locomotive vibration caused by fatigue stress under the action of lead poles fracture, according to preliminary statistics department, the failure rate of motor The total failure rate of about 30%. This quality accident can lead to motor burnout, poor commutation or even ring fire. In order to prevent the pole lead fracture, the main way is to be
