Die Cast Copper Rotors Market Size, Trends & Forecast [2031]

Report Description

Market Outlook:

The global die cast copper rotors market size was valued at USD 347.6 Million in 2022 and is anticipated to reach USD 820.1 Million by 2031, expanding at a CAGR of 10.7% during the forecast period.

The rotor refers to the rotating part of an electric machine, such as an electric motor or generator. It is the component that spins or rotates within the machine. The rotor is either wound or contains permanent magnets. Rotors are made from various materials; however, copper is widely used to manufacture die cast rotors. These rotors are made by pouring molten copper into a mold to create the desired shape. Copper rotors have higher electrical conductivity than aluminum rotors, which results in lower energy losses and improved motor efficiency. The use of copper in the conductor bars and end rings of induction motors in place of aluminum results in improved motor efficiency. Copper die cast rotors require 10-120C lower temperature to operate than aluminum die cast rotors, resulting in doubling the life of the insulation, thus increasing the service life of the motor.

Macro-economic Factors

Rising Industrialization

The industrial sector plays a key role in fostering socioeconomic resilience. Industrialization is driven by many factors, such as government policy, labor-saving inventions, entrepreneurial ambitions, and demand for goods and services. Industrialization has a significant impact on the mass production of goods and services across the globe. Thus, industrialization contributes to economic growth by enhancing productivity, innovations, and exports throughout the globe. This has surged the production of various essential materials, such as food and beverage, chemicals, and pharmaceuticals. Die cast copper rotors are used in electric motors, such as AC & DC motors. The rising demand for AC motors from the electric vehicle manufacturing and wastewater management industries influences the demand for die cast copper rotors. Thus, industrialization impacts the manufacturing sector and significantly influences the market.

Raw Materials Availability

The availability of raw materials is an important part of the manufacturing process for manufacturing any product. Die cast copper rotor manufacturers ensure the availability of raw materials inventory to ensure the flow of the production process with good quality, proper time management, and effective cost. Copper is heavily used to manufacture die cast rotors. Die cast copper rotor manufacturers often plan their procurement logistic process to ensure adequate raw material inventory to create finished products and cater the industrial demand.

Chile, China, and the US are the major producers of copper across the globe. China is at the forefront of manufacturing electric motors. The abundant availability of copper in China streamlines die cast copper rotor production for China-based manufacturers. However, manufacturers outside China are required to import raw materials to make enough inventory. Thus, the availability of raw materials is an important factor that influence the market.

Government Regulations

Government regulations affect business structure, location, environmental practices, employee practices, and advertising practices among others. In the case of die cast copper rotor production, energy efficiency concerns are the prime factors considered by the government. The International Standard IEC ensures a common base for electric motor designing and classification, as well as for national legislative activities, increasing the level of harmonization in MEPS (Minimum Energy Performance Standard) across the globe. This limits the capacity of the manufacturing units, which directly impacts the die cast copper rotors market.

Market Dynamics

Market Driver – Rising demand for electric motors in wastewater management

Electric motors with copper rotors play an important role in wastewater management to provide the power to operate various critical equipment. Electric motors used for water pumps include submersible motors, which are designed to be submerged in the water and are commonly used in deep well pumps and sewage pumps. The demand for proper wastewater management increases with the increasing various industrial activities, which further propels the demand for die cast copper rotors.

Market Driver - Increasing demand for electric vehicles with improved efficiency

Electric vehicles (EVs) have gained significant traction as a viable and sustainable transportation option, with advancements in technology, increasing environmental consciousness, and supportive government policies. Consumers and industries are rapidly shifting to electric vehicles to reduce their carbon footprint and contribute to a green future, as concerns over climatic change and air pollution intensify. Furthermore, the performance of electric motors used in EVs needs to be optimized to obtain high efficiency. Thus, electric vehicle manufacturers are adopting copper rotors to obtain maximum efficiency, thereby boosting the market

Market Restraint – Availability of substitute product

One of the major restraints of the die cast copper rotor market is the availability of substitute products, such as aluminum rotors, for electric motors. Rotors made of aluminum melt with low impurity contents, and hence high electrical conductivity results in enhanced motor efficiency. Moreover, the aluminum rotors used in motors are cheaper as compared to die cast copper rotors. Thus, wide availability of aluminum rotors affects the market of die cast copper rotors.

Market Opportunity - Rising inclination toward energy efficient products

Improving energy efficiency of products reduces individual utility bills and help stabilize electricity prices and volatility. Based on product energy efficiency, the IEC International Efficiency 60034-30-1 standard classified motors into four International Efficiency (IE) classes: IE1, IE2, IE3, and IE4. IE3 and IE4 motors design differs than IE2 motors to achieve higher efficiency. IE3 and IE4 motors feature a high amount of copper and steel, which makes a significant difference in efficiency. These motors possess a wide power range and improved protection standards. For instance, the government mandated that three-phase electric motors ranging from 75 to 200 kW required IE4 for two, four, and six-pole single speed motors when used within the EU. The new regulations for IE are based on the EU eco design. The goal is to reduce CO2 emissions from the industrial sector, where around 8 billion electric motors account for 45% of the total electrical energy consumption. The rising inclination to improve the energy efficiency of motors boosts the production of IE4 motors, which further fuels the die cast copper rotors market.
