Experimental results on a 450 kW active stator machine in a regenerative test rig

A dedicated four-quadrant regenerative experimental test rig was built to perform various tests on a 15-phase Active Stator machine and its associated drive system. Machine no-load characteristics were investigated and a number of on-load tests were conducted for both motoring and generating modes of operations. The machine stator winding commutating inductance was calculated using voltage and current data from tests under load conditions and compared with inductance measurements at standstill. Calculated and measured values were in good agreement. Various voltages and currents waveforms were captured on both the network bridge and the machine´s electronic commutator.
