AbstractThis invention provides a unique system for measuring torque and speed characteristics of motors. 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.
