IE3-Motors | energy-saving motor with copper in the rotor
The specific conductivity of copper is approx. 60% greater than that of aluminium. By using copper as the conductor material for the squirrel cage instead of aluminium, rotor losses are considerably reduced. This results in the following differences compared with the aluminium motor: The slip under load, which is proportional to the rotor losses, is considerably less. The torque curve in the operating region is considerably steeper. The breakdown torque is attained with a lower slip. The staring torque, which is proportional to the rotor losses, is considerably lower. Compared to the aluminium motor, in the energy-saving motor with a copper rotor, an increase in the amount of iron is only necessary to a moderate extent, or can be dispensed with entirely. Here too, the exclusive use of copper is not sufficient. Stampings with lower specific core losses, larger conductor cross-sections in the windings and flux-optimised windings are important components of this design.
