摘　　要：该文将Matlab的仿真技术应用于三相笼型异步电动机反接制动特性的电机学教学过程中,通过由三相交流电压源、三相配电变压器、匹配并联电容器和三相笼型异步电动机构成的主电路在负载转矩随转速变化的负载条件下的起动特性、反接制动特性仿真,呈现其电压、电流、转矩、转速的波形变化趋势,提供一种电机学理论形象化、直观化的教学手段。In this paper,the simulation technology of Matlab is applied to the electromechanical teaching process of reverse braking characteristics of three-phase cage asynchronous motor.The starting characteristics and reverse braking characteristics of the main circuit composed of three-phase AC voltage source,three-phase distribution transformer,matching shunt capacitor and three-phase cage asynchronous motor under the load condition of load torque varying with speed are simulated,which presents the changing trend of the waveform of voltage,current,torque and rotational speed,and provides a visual teaching method of motor theory.
