Recently, a new type of green steel has been put into mass production on a large scale in Taiwan Province. This kind of electromagnetic steel sheet is of high grade, has the characteristics of high efficiency, low energy consumption, etc., and can be widely used in the production of electric vehicle drive motors.
New electromagnetic steel sheet is more "green" to help the motor significantly improve efficiency
According to Gasgoo.com, the electric vehicle drive motor produced with this new type of electromagnetic steel sheet has the characteristics of high torque and high efficiency. Therefore, it is considered by the industry to be a new wave of power to promote the global electric vehicle industry, and the prospects are promising.
At present, the world’s major automakers are fiercely competing in the field of electric vehicles, and all companies are active in the research and development of electric vehicles. They all hope to develop electric vehicle products that meet market needs, and use drive motors instead of fuel engines to reduce The purpose of automobile exhaust emissions. Gasgoo.com learned that because of the fast speed and high power of the drive motor of electric vehicles, the requirements for manufacturing materials are also extremely strict. In order not to limit the efficiency of the motor, which ultimately affects the mileage of the vehicle, it is very important to develop new electromagnetic steel materials.
The ratio of output power to input power is the efficiency of the motor. When the input power is fixed, the more the loss, the lower the output power, and the efficiency of the motor decreases. Therefore, to improve the efficiency of the motor, it should be the starting point to reduce its loss. According to Gasgoo.com, the loss of a motor is reflected in two aspects: electromagnetic loss (including iron loss and copper loss) and mechanical loss. The electromagnetic loss is approximately 70% of the total loss, which is the main source of motor loss.
Since the electromagnetic loss has a direct relationship with the electromagnetic characteristics of the electromagnetic steel sheet, the use of suitable electromagnetic steel sheet to reduce iron loss and copper loss can significantly improve the efficiency of the motor.
Based on this, Taiwanese enterprises have made great efforts in the research and development of electromagnetic steel sheets. After more than four years of hard work, the new green electromagnetic steel sheet has been put into mass production, and its iron loss is only 1.9 watts per kilogram, which is a significant breakthrough compared with similar products on the market. Gasgoo.com learned that this new type of electromagnetic steel sheet has been supplied to motor manufacturers.
China attaches great importance to the research and development of new energy vehicle motors and core materials
As a key component, the drive motor has already been included in one of the key breakthroughs in China's new energy vehicle research and development from the policy level. The "Energy-saving and New Energy Automobile Industry Development Plan (2012-2020)" released in 2012 clearly pointed out that "strengthen the research and development of key components of new energy vehicles, and focus on supporting the research and development of drive motor systems and core materials and other electrified accessories", "development A group of key component companies that meet the requirements of industrial chain aggregation and have strong technological innovation capabilities have cultivated 2-3 key companies in the fields of drive motors."
Electric vehicles use electric drive systems instead of mechanical propulsion systems, and power batteries instead of traditional fuel engines. Under the premise of reducing emissions or zero emissions, they can achieve the same requirements as fuel vehicles in terms of performance and indicators. Therefore, the motor drive system of an electric vehicle should meet the following requirements when designing: large torque below the base speed to meet the requirements of rapid start, acceleration, load climbing, frequent start and stop, etc., small torque above the base speed, constant power, and relatively Wide speed adjustment range; efficiency optimization in the entire torque/speed operating range to achieve the longest possible cruising range after a single charge of the power battery; small size, light weight, and tight structure of the motor and electronic control device; low cost.
In order to develop drive motors that meet the above requirements and have higher energy efficiency, motor design and manufacturing companies should not only increase R&D efforts in terms of structure, but also closely integrate upstream material suppliers and actively explore new motor materials. Very meaningful.
Has been favored by well-known electric vehicle manufacturers, and is expected to accelerate mainland new energy vehicles
This new type of electromagnetic steel sheet has the characteristics of excellent flatness, low energy consumption, and high efficiency, and can be used in high-end fields such as pure electric vehicles, hybrid electric vehicles, and high-speed rail vehicles. At present, Tesla, a world-renowned electric car manufacturer, has become a user of this material.
According to Gasgoo.com, Taiwanese companies that produce this new material have already put into production their first project in the mainland as early as 2011. The annual production capacity of the new electromagnetic steel in Taiwan Province is planned to reach 150,000 tons. As a result, the company has become a world-class supplier of high-standard electromagnetic steel sheets.
As an important global market, China's new energy vehicle production and sales have risen rapidly this year, showing strong market demand. Electromagnetic steel sheet is one of the direct factors that determine the operating efficiency of the motor, which indirectly affects the mileage of electric vehicles. The new high-grade electromagnetic steel sheet put into mass production in Taiwan Province this time is believed to attract the attention of domestic motor manufacturers and be applied on a large scale, thereby "speeding up" the development of China's new energy vehicles.
