| Abstract: | The article puts forward a new experiment system for testing the running characteristic of electric motor at four quadrants at different frequency and analyses the influence of the value of the torque and the sign of frequency to the running characteristic of electric motor under different frequency. The article gives up the principle of system structure, control principle and experiment results. Compared with traditional method, this system is easy to change the wiring and it can also save energy remarkably. |
