The cast copper rotor from Shanghai Metal Corporation is a new type of motor rotor with copper as the conductive matrix. 

The electrical conductivity of copper is about 40% higher than that of aluminum. The cast copper rotor is used to replace the 

cast aluminum rotor widely used in the squirrel cage three-phase asynchronous motor. The total loss of the motor will be 

significantly reduced, thus improving the overall efficiency of the electric machine.

Features of Copper Rotor:
1. Energy Efficient
2. Long Life
3. Smoother operation
4. Lower manufacturing cost
5. Allows better momentary overload
6. Higher torque
7. Sleek design
8. Lower noise level

Copper high pressure die casting requires a high purity of the melted mass and a casting temperature of approx. 1,150 °C. These prerequisites are in place and therefore cost-effective series production is possible. In order to further improve the efficiency of energy-saving motors, the cage cast in the motor’s rotor can be manufactured using copper instead of aluminium high pressure die casting.
