摘　　要：该文将MATLAB的仿真技术应用于三相笼型异步电动机能耗制动特性的电机学教改过程中。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正比变化及随转速正比和平方变化的负载条件下的起动特性、能耗制动特性仿真,呈现其电压、电流、转矩和转速的波形变化趋势,提供一种电机学理论形象化、直观化的手段。In this paper,MATLAB simulation technology is applied to the electromechanical teaching process of energy-consuming braking characteristics of three-phase cage asynchronous motors.Through the simulation of starting characteristics and energy-consuming braking characteristics of the main circuit composed of a three-phase AC voltage source,a three-phase distribution transformer,a matched parallel capacitor and a three-phase cage asynchronous motor under the load conditions where the load torque changes in proportion to the speed and changes in proportion to the square of the speed,the waveform change trends of the voltage,current,torque,and speed are presented.This provides a means to visualize and intuitively visualize electrical engineering theory.
