降低串激电机包轴转子漆前耐压击穿失效率的试验研究

Experimental Study on Reducing the Voltage Resistance Test Failure Rate of Universal Motor Rotor

耐压测试击穿是导致包轴转子失效的主要原因,针对包轴转子滴漆前工序绝缘耐压失效,对串激电机转子的主要制造工序进行了大量的耐压试验测试,分析了其对失效率的影响。采取了增加绝缘环氧用量、成型压力、烘干时间等改进措施,并通过耐压试验验证了改进措施的有效性。

Voltage resistance test failure is the main cause of the rotor failure. To solve the insulation failure before the drop paint process, this paper tests the main manufacturing process of motor rotor, and analyzes its influence on the failure rate. We carry out some improvement measures such as increasing the amount of insulation epoxy, molding pressure and drying time. The effectiveness of the improved measure is verified by voltage resistance test.
