As the global automotive industry accelerates towards electrification and intelligence, BYD’s latest model, the DENZA Z9GT, made a strong debut, capturing widespread attention with its distinctive hunting-style design and outstanding performance. The DENZA Z9GT is equipped with BYD’s self-developed “Yi San Fang” triple motor technology, achieving a maximum power output of nearly 1000 horsepower. Technically, it also achieves comprehensive coverage of both pure electric and hybrid platforms, meeting the diverse needs of different consumers.
The "Yi San Fang" platform is the world's first integrated intelligent control technology platform that realizes the independent driving of three motors and the independent steering of dual rear motors. It fully integrates top-notch technological advantages such as the fifth-generation DM technology and the e-Platform 3.0Evo, creating a "master of BYD technology" that builds the world's leading dual-platform for plug-in hybrid and pure electric vehicles. It perfectly integrates the power architecture of the plug-in hybrid and pure electric on the same platform, the world's first triple-motor independent driving + dual rear motor independent steering control architecture, and the intelligent fusion of the whole vehicle's intelligent architecture. This allows the car to boast formidable power, agile control, and a safe and comfortable driving experience.
Innovative Rear-Wheel Dual-Motor Independent Steering Technology of DENZA Z9GT
BYD’s new model - DENZA Z9GT, is equipped with an original rear-wheel dual-motor independent steering technology, with a maximum steering angle of 20 degrees, making it the model with the largest steering angle among mass-produced cars in the world. Moreover, it has pioneered the adjustment forms of “inward eight” and “outward eight” for the rear axle tires, making a significant technological breakthrough. The inward eight form increases forward friction, reducing braking distance, while the outward eight form enables new forms of vehicle movement.
The innovative technology enables independent steering control for the dual rear motors, allowing for more agile vehicle steering with a maximum steering angle of 20 degrees, significantly reducing the vehicle’s turning radius. This makes the DENZA Z9GT capable of easily turning or making U-turns on narrow roads or in complex road conditions. Additionally, the rear-wheel steering technology enhances the vehicle’s handling stability and safety, providing better stability and control during high-speed driving or emergency avoidance.
BYD’s significant technological breakthrough, the “Yi San Fang” and the dual-motor independent steering technology for the rear wheels are not only focused on their technological breakthrough but also on their impact on the future development trends of electric vehicles. With continued technological breakthroughs and innovations, electric vehicles are inevitably moving towards being smarter, more energy-efficient, more environmentally friendly, and more convenient. This also serves as a dynamic indication of the direction for research and development and innovation for enterprises in the intelligent manufacturing of electric motors.
The Burgeoning Electric Vehicle Industry has Infused Momentum into the Development of Electric Motors
Global EV Growth and Policy Support
Amidst the global fight against climate change, the electric vehicle sector is flourishing, emerging as a pivotal force in energy conservation, environmental protection, and sustainable development. This rapid growth is also attributed to the increased policy support from governments worldwide. For instance, the Norwegian government offers incentives such as tax breaks, free parking, and the use of bus lanes; the U.S. government provides tax credits for EV buyers; the Thai government exempts electric vehicles from import duties; and the Chinese government has implemented a range of measures including financial subsidies and tax incentives, directly propelling the rapid development of the new energy vehicle industry and making China the world's largest market for new energy vehicles. These policies have not only stimulated market demand for electric vehicles but also provided a boost to the electric motor industry.
Rising Demand: The Expanding Electric Motor Market
As a key component of electric vehicles, the electric motor industry is facing new development opportunities, with its market demand and industry scale expanding accordingly. Statistics show that as early as 2021, the installed volume of drive motors for new energy vehicles in China reached 3.415 million units, a year-on-year increase of 142.3%[1]. This significant growth not only reflects the strong market demand for electric vehicles but also indicates a broad prospect for the electric motor industry. Moreover, the demand for electric motors in the new energy passenger car market accounts for 94.7%, making it the largest segment, while the demand for new energy buses and special vehicles accounts for 2.5% and 2.8% respectively[2].
Technological Advancements in Electric Vehicle Motors
Technological innovation is a key factor driving the development of the electric vehicle industry. The application of advanced technologies such as permanent magnet synchronous motors (PMSM) and switched reluctance motors (SRM) not only enhances the performance of electric vehicles but also strengthens their market competitiveness. These technologies provide a more reliable and comfortable driving experience by improving energy efficiency, reducing noise, and extending motor life. PMSMs use high-performance permanent magnets to achieve more efficient electrical energy conversion, with the advantages of high efficiency, high power density, and high reliability. SRMs, with their energy-saving effects and wide speed range, have broad application potential in areas such as transportation vehicle drives and forging equipment.
To meet the market demand for high-performance, reliable motors, motor manufacturers are facing fierce market competition. Therefore, they need to seek out higher-quality suppliers of automotive motor production equipment to upgrade motor performance and capture market share.
Companies in the industry are mainly divided into two categories: one is new energy vehicle manufacturers with the capability for integrated development and production of electric drive systems; the other is third-party motor system suppliers with profound technical accumulation. These companies continuously improve their market competitiveness through technological innovation and product upgrades.
