This paper introduces the simulating method of circuit and motor using Power Systems Blockset in MATLAB. We not only build a model of circuit and make the simulated analysis of its sine steady state but also build a model of motor and get its work characteristic. The starting process of a rounding asynchronous motor by serially interconnecting a resistor into its rotor loop is simulated. The result is consistent with theory analysis and the way is simple. It shows the way is applicable for analyzing the sine steady state of circuits and dynamic simulation of asynchronous motors. This method can urge the students' understanding concepts and can also replace of the parts of real objects experiments.
