Development of a measurement system to test the efficiency of electrical generators for energy recovery on aircraft actuators

In this paper a measurement system for the characterization of electrical generators for the energy recovery from EMAs installed on airplanes is presented. The measurement system uses both mechanical transducers (position/speed/ — force) for the measure of mechanical power and electrical transducers (current — voltage) for the measure of electrical power. A test bench has been developed for the characterization and for the efficiency evaluation of the system for different values of speed, screw pitch and current supplied by the generator.
