Core Viewpoint - The future of electric motors will be dominated by flat wire motors, as emphasized by Long Weiguo, the chairman of Mawi Power, during a media communication [2]. Group 1: Electric Motor Technology Development - Major automotive manufacturers are actively researching and developing next-generation electric drive technologies, with BMW starting its electric drive research as early as 2003-2004 [2]. - Mawi Power has been involved in the joint development of electric drive technology with BMW since its establishment in 1999, leading to the mass production of its hybrid magnetic motor technology in 2010 [2]. - The hybrid magnetic motor technology has been adopted by several high-end brands, including Tesla, Ferrari, and Aston Martin [2]. Group 2: Hybrid Magnetic Motor Characteristics - The hybrid magnetic motor differs from traditional permanent magnet synchronous motors by not pursuing the highest speed at rated power, but still meeting performance requirements under extreme conditions [4]. - Tesla's latest Model S and Roadster models have adopted hybrid magnetic motor technology, indicating a shift in industry focus [3][4]. - Mawi Power has developed a patented asymmetric magnetic isolation bridge technology to address vibration issues associated with hybrid magnetic motors, significantly reducing overall vibration amplitude [5]. Group 3: Performance and Cost Considerations - The industry trend is towards high-speed motors, with speeds reaching 25,000 to 35,000 RPM, but practical applications in domestic road conditions may not require such high speeds [6]. - Mawi Power emphasizes that the key to electric motor performance lies in improving power density using existing materials rather than merely increasing RPM [6]. - The automotive industry is facing intense cost pressures, necessitating extreme cost control across all components, including electric motors [6]. Group 4: Key Performance Indicators - The four simple standards for evaluating electric motors are power, torque, efficiency, and weight, with safety and reliability being paramount [7]. - Achieving an energy density of over 10 kW/kg is considered leading in the industry [7]. Group 5: Technological Breakthroughs - Mawi Power has developed a new immersion oil cooling solution that can double the rated torque and power of electric motors, representing a significant advancement in performance [8][9]. - The company’s hybrid magnetic motor has achieved a power density of 17.4 kW/kg without using special materials, showcasing its potential for future electric drive development [9]. - The immersion oil cooling technology enhances thermal efficiency and reduces losses, leading to improved overall performance [9][10]. Group 6: Industry Competition and Research - The automotive industry is entering a critical phase of competition, with suppliers needing to innovate and improve performance without increasing costs [10]. - Long Weiguo advocates for deeper research and development within the industry, emphasizing the importance of foundational research rather than merely following foreign innovations [10].
