通过电机高转速对电机轴承的影响、电机在安装后轴承受力情况以及机车时速与电机转速对应情况等几方面对电机高转速下空转情况进行分析,提出电机不以最高转速进行空转考核的观点
Through the influence of motor high speed on motor bearing, bearing force of motor after installation and corresponding situation of locomotive speed and motor speed, this paper analyzes the idling situation of motor under high speed and puts forward the viewpoint that motor does not idling at the highest speed
