交流电机转子铜端环与导条整体感应钎焊加热器研制

摘要

AC motor rotor end ring and conducting bar welding,the whole induction heating by induction heater on the end ring bar,realize induction brazing,therefore,to realize the welding of rotor end ring copper bar,the induction heater is a key link of development This article through several aspects of rotor end ring bar welding induction heater design principle,induction heater composition,induction heater and end ring assembly form,application of induction heater evaluation to develop a reliable induction heater,to solve the problem of AC motor rotor copper end ring and guide bar welding integral induction heating,guarantee the motor rotor end ring bar welding quality.%焊接交流电机转子铜端环与导条时,通过感应加热器对端环导条进行整体感应加热,实现感应钎焊;要实现交流电机转子铜端环与导条的焊接,感应加热器的研制是关键环节.从转子端环与导条焊接感应加热器的设计原则、感应加热器的组成、感应加热器与端环的装配形式、感应加热器应用效果评估等几方面着手,研制了一种可靠的感应加热器,解决了交流电机转子铜端环与导条焊接整体感应加热问题,保证了电机转子端环与导条焊接质量.
