Motor TestsCopper rotor consistency? Copper rotor motors averaged 90.7% efficiencyRange: 90.6% – 90.8%? Copper rotor losses averaged 157 WattsRange: 153 Watts – 167 Watts? Stray load losses were down 23%? Process variables tested had no predictable affect onfinal test results? No balancing weights were required? This is a very robust process with consistencynot seen in current rotor die casting methods
Motor TestsMotor designed around a copper rotorTests of an “optimized” copper motor? Rotor losses - 40%? Total losses - 23%? Temperature rise - 41%? Efficiency + 1.6% 90.9% vs. 92.5%Stator windings and iron core were modified from standardmotor design to gain best possible results
