摘　　要：利用中频电机的特性,把单台发电机供电给单台电动机时,可以直接改变发电机的输出频率来改变电动机的转速的理论,应用到电传动汽车设计上来变频节能,通过控制原动机转速,带动无须稳压装置的稀土永磁无铁芯盘式三相交流发电机发电,发电机输出电压、频率与原动机转速成正比变化,输出特性较变频器更好,直接供电给中频电动机来实时驱动车辆,制作实验模型,录取实验数据,其结果表明,该装置符合设计原理,改善电传动车辆的缺陷,能广泛应用到所有道路车辆上,同时为专用电机设计提供新的思路。The characteristics of intermediate frequency motor, and the theory that when a single generator is supplied to a single motor, the output frequency of the generator can be changed directly to change the speed of the motor, can be used to design electric drive vehicle and save energy. By controlling the speed of prime mover, with no voltage stabilizing device of rare earth permanent magnet coreless disk type three-phase AC generator, the generator output voltage, frequency and prime mover speed is proportional to the change, the output characteristics of inverter is better. To directly supply power to the motor and driving the vehicle in real time, create an experimental model, and record the data, results showed that the device conforms the design principles and improve the defects of the electric drive vehicles, which can be widely applied to all vehicles, and provide a new idea for the design of special motor.
