客车5千瓦感应子发电机(以下简称5千瓦电机),经过10多年的运用,发现电机温升有偏高的现象,有必要加以改进。最近,通过走访一些车辆段并对电机作了一次全面的分析,找到了温升偏高的原因,制定了改进措施。温升偏高的主要原因有以下4点: 1.5千瓦电机装在转向架上,位于车辆下部,环境较恶劣。受雨水、灰尘的影响,再加上运行时的剧烈振动,以及目前电 Passenger 5-kilowatt induction generator (hereinafter referred to as 5-kilowatt motor), after 10 years of use, found that the motor temperature rise is high, it is necessary to be improved. Recently, by visiting some depots and making a thorough analysis of the electric motor, we found the reasons for the high temperature rise and formulated improvement measures. The main reason for the high temperature rise has the following four points: 1.5 kW motor mounted on the bogie, located in the lower part of the vehicle, the environment is harsh. Affected by rain and dust, coupled with severe vibration during operation, as well as current electricity
