This invention employs the principle of driving an induction generator beyond its synchronous speed until it generates power fed back into the power supply. Thus, a test motor can be loaded to its full load potential and only the losses of the test motor, generator, and other components are supplied by the power distribution system. Consequently, a substantial savings in cost are obtained compared to other conventional motor testing apparatus. | |
