Die-casting copper rotor technology - A die-casting copper rotor technology for high efficiency motor

DIE-CASTING COPPER ROTOR TECHNOLOGY is an advanced process for die-casting copper rotor.

Copper rotor is the rotor for copper squirrel cage induction motors which is made of copper and copper alloy and is pressed by die casting machine under high pressure and velocity. Die-casting copper rotor technology is small weight and improves the performance of the motor in its efficiency and electrical conductivity mitigation (40% less). It gets even more efficient using coper rotors when the motor is smaller and higher the percentage of the rotor losses accounted for the total motor losses. Due to the decrease of motor losses less energy is converted into heat which means the decreasing of working temperature of rotor as well as stator. The low working temperature means higher reliability and longer working life of the motor.
