Abstract :
A dynamometer capable of emulating linear, nonlinear and discontinuous loads for rotating systems is described. The controllable load is produced by a servo drive system. Applications for the dynamometer are steady state load tests and dynamical load tests with linear, nonlinear or discontinuous loads for testing of electrical machines in variable speed drive systems. The configuration of the dynamometer is presented, together with simulation models and simulation results. The simulated torque and speed time responses show that the dynamometer tracks the required torque with a high degree of accuracy, for both linear, nonlinear and discontinuous loads
