摘　　要：为研究燃料电池轿车驱动电机的电磁噪声,在调查了燃料电池轿车驱动电机的类型、功率和转矩等参数的基础上,选择感应电机为对象,测得了电机不同输入电压和转速下的电磁噪声频谱图,并进行对比分析。结果表明,在选定频率范围内,输入电压和转速对电机电磁噪声的均值和峰值均有影响,为采取降低燃料电池轿车驱动电机电磁噪声的措施提供了依据。For studying the electromagnetic noise of drive motors in fuel cell cars, induction motors are cho- sen as object based on a survey of the type, power, torque etc parameters of drive motors in fuel cell cars, and the frequency spectrograms of electromagnetic noise of drive motors are obtained by tests and comparatively analyzed. The results show that both input voltage and rotation speed have certain influence on＂ the mean and the peak electro- magnetic noise of motor, providing a basis for taking measures to reduce the electromagnetic noise of drive motors in fuel cell cars.
