1. Motor design and manufacturing: As a company with rich experience in electric vehicle development, BYD has in-depth research and mastery of motor design and manufacturing. They may have adopted efficient motor design, including optimized magnetic field distribution, suitable current control and high-quality materials, thus achieving higher speed.
2. Magnetic field control technology: The axial flux motor adopts advanced magnetic field control technology. Through reasonable magnetic field adjustment, the speed and efficiency of motor can be improved. BYD may have optimized the magnet selection, magnetic field distribution and magnetic field adjustment to make the motor reach a higher speed.
3. Control system optimization: In addition to the design of the motor itself, the control system also plays an important role in the speed of the motor. BYD may have optimized the control algorithm and controller hardware, so that the motor can run stably and reach a higher speed.
It should be noted that the rotational speed of the motor not only depends on the design and technology, but also is influenced by factors such as power supply voltage, load and temperature. Therefore, in practical use, it is necessary to consider the influence of these factors on the motor speed and make appropriate control and adjustment.
