Motors are one of the most important source of power. According to statistics, 46.2% of energy is consumped by motors worldwide. From household appliances to industrial machinary, motors powers every equipment. What kind of material forms a motor? More than 90% is metal. Here shows TECO high efficiency (IE3) 150 hp motor data:
Steel:54% Iron: 32% Copper: 6 % Aluminum:2 %
TECO has conducted a carbon footprint analysis of three high-efficiency motor models by "from cradle to gate" approach. Which calulated carbon emissions including raw material, manufacture process, direct manpower and waste generated. We found that 90% of carbon emissions come from the production of raw materials, and only 10% is from motor manufacture stage. This shows that the recycling of raw materials (metal parts) is important to reduce emission.

How does the raw material circulate? There are two cycles in TECO: "In-plant" and "Lifecycle"
TECO has own foundry in place, which means we have the ability to melt wastes from production process and re-manufacture it into motor frame bracket housing parts. We have now reached 27.3% of iron reusing rate.
Industrial motors typically have a design life of 10-15 years, and special designs can extend life up to more than 30 years. At the end of the motor life cycle, the motors are recycled and dismantled by the scrap hardware recycling service companies. 90% of motor total content, including steel, iron, copper and aluminum will be separated and returned to the raw material stage to be remelted and remanufactured. Steel is usually made into angled steel and other building materials that continue to exist in our lives.
