摘　　要：传统的测功设备是以水力测功机或电涡流测功机为主,所消耗的燃油和电能较高。介绍了一种机电耦合系统内馈能电力拖动?测功机组,克服了上述测功机的不足。该系统属于多轴混合型电力拖动系统,电能在系统内部形成回馈及再利用。它主要由馈能电机、驱动电机、同步发电机及用于吸收机械功率发出电力的交流发电机、励磁控制器、主控制台、主频调速器等组成。Traditional dynamometers in which water power dynamometers and electric eddy-current dynamometers predominate consume more fuel and electric energy.One electromechanical coupling intrasystem energy-feedback electric dragging?power-measuring machine set which overcomes the above shortcomings is introduced in the paper.The system is one of multi-axle hybrid type electric dragging system,in which electric power feeds back inside and is recycled.It consists of the energy feedback electric motor,the drive electric motor,the synchronous generator,the alternator absorbing mechani-cal energy,the excitation controller,the main console,the dominant frequency governor.Topic words :Dynamometer,Energy consumption,Principle,Design
