Electrical Steel help power the Revolution of Electric Motor Manufacturing

Electrical Steel help power the Revolution of Electric Motor Manufacturing

  • 2023/02/24

Electric motor manufacturing is an industry that has experienced steady growth over the years. With the push towards renewable energy and the need to reduce carbon emissions, there is an increasing demand for electric motors in various sectors, including automotive, industrial, and household appliances. As a result, manufacturers are investing heavily in research and development to improve the efficiency and performance of electric motors. One critical area of focus is the use of electrical steel, which is revolutionizing the industry.


Electrical steel, also known as silicon steel, is a type of steel that is optimized for use in magnetic applications. It has high magnetic permeability, low core loss, and low coercivity, making it ideal for use in electric motors and transformers. In electric motors, electrical steel is used to make the laminated cores of the stator and rotor. The laminations help reduce energy losses by minimizing eddy currents and hysteresis losses.


The use of electrical steel in electric motor manufacturing is not new. It has been in use for many years, but recent advancements in technology have led to the development of new grades of electrical steel that offer improved performance. One such example is the development of grain-oriented electrical steel, which has a highly oriented crystal structure that enhances magnetic properties. This type of electrical steel is now widely used in high-efficiency motors that require low energy losses.


The increasing demand for electric motors has led to a corresponding increase in demand for electrical steel. In response, manufacturers are investing in new production technologies that can produce electrical steel with better magnetic properties and higher efficiency. For example, some manufacturers are using advanced annealing techniques that create a more uniform crystal structure, resulting in lower energy losses and better performance.


Another area of focus is the development of thinner electrical steel laminations. Thinner laminations mean more laminations can be stacked together, resulting in a higher magnetic flux density and a more efficient motor. Manufacturers are also exploring the use of non-grain-oriented electrical steel in lower efficiency motors, which could help reduce costs.


The use of electrical steel is not limited to electric motors. It is also used in other applications such as transformers, generators, and inductors. However, the demand for electrical steel in electric motors is the largest, accounting for over 80% of the total electrical steel market.


As electric motor technology continues to evolve, the demand for electrical steel is expected to increase. According to a report by Grand View Research, the global electrical steel market is expected to reach $21.8 billion by 2027, growing at a CAGR of 6.2% from 2020 to 2027. The report cites the increasing adoption of electric vehicles and the push towards renewable energy as key drivers of the growth.


The adoption of electric vehicles is particularly significant. Electric vehicles require more electric motors compared to internal combustion engines, and each motor requires a significant amount of electrical steel. As the adoption of electric vehicles increases, so will the demand for electrical steel. In response, manufacturers are investing in new production technologies to increase capacity and improve efficiency.


One example is the development of new production methods that use less energy and produce less waste. For instance, some manufacturers are exploring the use of continuous annealing technology that can reduce energy consumption by up to 30%. Others are investing in advanced recycling techniques that can recover and reuse materials from end-of-life products, reducing waste and conserving resources.


The future of electric motor manufacturing is closely tied to the development of new and improved electrical steel. Advances in technology have led to the development of new grades of grain oriented electrical steel sheet and oriented electrical steel that offer improved performance, and manufacturers are investing in new production technologies to meet the increasing demand for electric motors. As the world shifts towards renewable energy and electric vehicles, the demand for electric motors and electrical steel is expected to continue to grow. This presents
