Electric motor manufacturing

In 2006, Yunnan Copper Co. Ltd. and Nanyang Explosion Protection Group Co. Ltd. established the joint venture Yunnan Copper Die Casting Co. Ltd. to commercialized copper rotor motors.^[5]

The International Copper Association, in collaboration with Yunnan Copper Die Casting, launched a program in 2013 to remanufacture old electric motors by replacing their aluminum rotors with cast copper rotors. This process significantly improves motor efficiency, allowing older models to meet modern energy efficiency standards.^[6]
