Abstract

A Sinusoidal Modulation technique is proposed for the synthetic loading of induction machines at full load based on power electronics control. The sinusoidal modulations are based on the two axis method and reference-frame theory. The method applies specifically to induction machines for which physical load testing is unadvisable or unattainable. This allows motor manufactures to fully test their products while utilizing current motor production as the basic setup of their test system decreasing costs.

Previous modulation technique methods are either too costly or incur high oscillation currents rendering the systems impractical. The Sinusoidal Modulation technique computer simulations show the ability of the method to suppress power fluctuations on the driver motor of the system. Experimental and simulation results are analyzed and compared to prove simulation accuracy and system viability. Experimental data gathered at half rated load show maximum fluctuations on the driver motor in the range of 2%.
