Abstract: To keep pace with the times, the basic teaching experimental system of electric machines is developed based on virtual instrument under traditional motor laboratory conditions. The whole paper focuses on the classic experimental software and hardware design of both asynchronous motor and synchronous generator , p-q theory, the event structure. The experimental results show that the purpose of simultaneous and real-time fast and accurate measurement and processing of various physical quantities such as voltage, current, active power, reactive power, torque, speed of electric machines is achieved.
